If you guys are thinking of doing this be sure to get a power bank that Explicitly says Pass-Through Charging as the author of this video states. Most of the cheap USB powerbanks on eBay, Amazon, etc. do not have this feature because it requires more components to make and is more expensive. This is important because what the cheap ones do is always take power from the battery even when the powerbank is plugged in for charging. This means the battery is continuously being discharged and charged which will wear out the battery prematurely. Thanks for posting this video & Happy New Year !
Yes had a similar question for the uploader. I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously. However I want to be sure if it is actually pass through charger or is it just taking power from the battery and powering the router and then the power bank charging it self when the battery drops below 100. Pass through charging should simply connect the power input to the out of the power bank unit if the power bank itself is fully charged. If this doesn't happen then it will simply keep consuming battery cycles of the power bank as it will keep charging as soon as it drops below 100.
I'd like how he make simplified things especially this one that relates to UPS for wireless router. Not that I'm against those that made their own "mini UPS" say using lithium-ion with BMS but this one right here is practically easy to follow and cost-effective too. Cheers Gadget Addict
Something I forgot to mention is that ideally you want to use a USB cable with thick wires inside. If the wires aren't so thick, make the cable shorter.

A new (2020+) version of this trick is to use a USB-C PD power bank with passthrough charging, combined with a "PD emulator" or "PD decoy" adaptor, to create custom voltages (e.g. 9V or 15V or 20V) at high power (e.g. up to 100 watts). This can power some more beefy electronics!
This is a lot of electronics stuff i don't understand. Can you please specify which devices exactly to buy and recommendations, also maybe how to set it up, thanks
@@olukolatimidavid8318 I know I am late but, what this user wanted to say is that: 1)Nowadays most phones to charge quickly, they require larger amounts of power. So, what companies did was, they made it so that devices can receive and transmit more power through usb. Usually, the standard for usb is 5v 1a, but most phones can accept 12v 1.5a or more through usb. Coincidentally, that's the voltage most routers/modems run on. 2)Thus, most smartphone chargers and powerbanks have to communicate with the phone to agree on what voltage is acceptable. If you look at the specs on your phone charger/powerbank, you will see that it might say that it outputs a wide range/variety of voltages. 3)So, what some smart people have done is, they took the little chip that makes the agreement between the phone and the charger, they put it on a small board that can accept usb input and output with various other ways (ie usb, dc jack etc) and this way they managed to create their own ups out of a powerbank. You can usually find these boards really cheap on sites like aliexpress with various names (pd decoy, pd trigger, qc trigger etc). You can buy a board like this, find some old power brick that fits in your router's/modem's power jack, cut and strip the cable, wire it to the board's output (be careful with the polarity, the device you want to power (or the power brick of said device) should have an image that shows the polarity. Usually, red is positive and black is ground/negative), set it up to its correct voltage (the board should come with a manual. If not, consult the seller),connect your powerbank on the board and the other cable to your router/modem and boom you just made a ups for your router/modem. If you don't understand how this all works, I would suggest you consult a more electronically savvy person to help you build it.

thanks a lot you just saved me from paying 50$ , i was lucky i had this cable that you custom built it , first it did turn on with no internet connection , i tried your tip about using short cables and it worked !!! thanks a lot
This is a very good concept, but it doesn't always work. I tried this myself, and I didn't have much luck. 2 out of the 3 routers I tried failed to function. The first one I tried was my main modem/router combo, which didn't work. Then I tried my standard inexpensive Cisco router which also failed to function. The one that I got to work was an old Westwood modem/router combo from my old DSL connection. I checked and made sure the polarity was correct and I checked my multimeter to confirm my wiring was correct and it tested 5.1 volts positive on inside and negative outside of the barrel connector. I tried a couple different power banks too but the results were the same. If anyone wants to try this, I definitely recommend that you do NOT cut up your main wire, but instead buy that terminal he used in the video, or cut up an old one that you don't use anymore, because there is no guarantee that this will work for you.
What's the maximum output of your powerbank, 1A or 2A? Did you use a good quality USB cable with thick power wires inside? What were the power ratings on the 2 devices it didn't work with? And yes, cutting up an old unused cable would be better than cutting up your current one. Most people have an old power supply in a draw that has a matching DC barrel connector.
Gadget Addict The power banks I tried were up to 2.4 amps, I tried the 1 amp port and the 2.4 amp port. The first All were 12 volt requirement and the 1st one had a 1.5 amp input and the other 2 had roughly 1amp input, one of the 1 amp ones did work
Yeah for higher power routers use a usb step-up cable to get 12V output. Or better, use a powerbank with Qualcomm quick charge and buy a 12V trigger cable.
I have a Mini DC UPS. But the manual is clearly translated from another language and not very helpful. 1) Do I leave the Mini DC UPS plugged in with its power cable? 2) Do I keep the Mini DC UPS powered on at all times? Struggling with constant loadshedding.4
Notice: for illustrate real ups functionality you should look for a powerbank that keeps discharging when in use. (some of them do "power reset" for 1 second when the main power stop charge the powerbank)
Really great detailed video. But I still have a question. Is it safe to keep powerbank charging all the time ? Won't it create heating issue or degrade of battery ?
Need ur help please man 🙏 Here is the problem All the internet system has to power adapters one says 9v - 500mA for router The other is 18v - 660mA for the internet dish i switched them and they work just fine but i want to power it from a bower bank i got two 9volt usb cables the dish led looks so dim so is it that there isn't enough power but why switching adpters works good
undervolting long term could potentially cause damage, not to mention on the router it may not be able to supply enough power to fully power the WiFi antena's. Would not recommend unless you have a small area for WiFi or using cat5 only.
Wouldn't the constant charging destroy the power bank since it has 500 charge cycles or does the USB wall charge does a trickle charge? Also how would one look for a pass trough charging I have a idea or a solar panel that charges a power bank that charges a rechargeable light
It depends on your powerbank. Some support pass through charging where the power from your AC supply bypasses the battery cells and goes straight into whatever you have connected to the powerbank. Of course it will still need to trickle charge the cells now and then to keep them topped up. The specs listed on the sales page usually indicate if this is possible.
Gadget Addict so pretty much the 500 charge cycles won't be affected? Or the life span of a power bank doing this for a "fail safe" in case of power outage?
A charge cycle is a full discharge and recharge. Most of the time it will stay trickle charged from the AC. Provided you buy an appropriate powerbank, there should be no longevity issue.
for fibre routers and ONT you can get 2 USB to DC cables with a step up power module to convert the USB 5v to a proper 12v 2.1A input. Li-on power banks are cheaper than ever, I can buy a 60 000mah power bank with multiple USB and USB-C ports with passthrough charging and fast charge capabilities for about $65. In countries like mine where we lose power from 2 to 4hrs at a time multiple times a day this works wonders and is cheaper than router UPS options with a lot less capacity.
Hello. If my internet connection has no bundled telephone, I will not be able to use this trick? I am using skycable broadband internet. What are my options? I hope you can help me
When you undervolt a device it may try to use the same power, which is current times voltage. As a result, there might be 2 or 3 times the current going through the wires with 5V compared to 12V. Would be good to make sure the connectors and wires are good to go for higher amperage.
I think your video is awesome. I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously.

sir my problem is , i have to make a ups using power bank... i just used 5v to 12v step up module.for my router. connected it with power bank and using router continuously. but the problem is i cant use the power bank while connected through power outlet... there is switching issue happens.. while powers off and power on.. time... approx 2 second.... how to prevent that power bank behavior? i am using mi powerbank
I have a question. When the powerbank is fully charged and it is still connected to the charger that is charging it, and the router is connected to the powerbank and switched on - in this scenario, does the router then end up drawing power from the current flowing in from the charger directly, and the battery in the powerbank is, well, inactive or something?
most Power banks come with adaptive circuitry to support 5/9/12 v outputs by default depending on the load you plug in. Because most modern fast charging devices demand them.
thanks for the vid man was planning to buy a 5 to 12v step up cable then i came across your vid and my lte wifi modem worked fine thenks a lot :) real helpfull keep up the good work :)
Cool idea and you don't have to butcher a USB cable or fiddle with an adapter at all. They make USB to DC cables, I actually bought one recently so I could charge my hand vacuum in my car with USB.
i have tried this....i used powerbank to power my zte 12v router but the problem is that only the red power light comes on and it doesnt go any further...need help
Can you confirm if all power banks that support pass though provide uninterrupted supply when main goes off ? Can you recommend brands which are uninterrupted regardless of power status changes ? I have 2 power banks xiaomi and another brand both interrupt output when main power status changes
Hi, I want to use your router/powerbank trick but I dont know how to check the polarity so that I can connect the right wires. I only have a clamp meter 266 and I have already severed the wire of the adapter. Can you help me identify which is the load wire and which one is earth/neutral?
I did try this idea with my binatone 9v modem, the power bank powers the modem. Only the PWR and the Wi-Fi LED glow. Neither the ADSL nor the internet LED glows. I also tried by keeping the USB cable shorter, the modem powers on but the internet doesn't come. Any kind of work around you would want to suggest such as using a power booster? If yes, then which is that instrument and how?
There's the occasional modem that it won't work with. You can buy a boost converter on eBay which can increase the voltage to 9V. Have you tried a cable with thicker wires and a higher output USB charger/powerbank?
Had a question about the power bank ups suggested by you. Is it a good idea to have this as a permanent solution? What are the chances of fire, due to continued charging of the power bank and the router? Have you used it for a long time and found any pointers that you can share. Thanks
Won't this damage the router in the long run? also If it requires a certain amount of power then with lower voltage the ampage will go up, won't that potentially burn the tiny USB wires?
With 16000mAh power bank input 5V/2A, output 5V/2.1A and cable 2 meters long, the router boots up. But router keep rebooting once wifi is active. Is it because router is not getting enough power? How to fix this?
What i observe about this method is it might work 50/50. Imagine you have 12v light bulb powering 5v only. Youll never get that bright power output of 12v so there is a performance lost here. In this case using 5v only in 12v gadget. Yes led will work cause it uses low voltage but some components in board might not work properly. It doesnt mean led light up at 5v will perform 100% of system. Like what i said in some gadget this might work. Good review.
Thankfully most budget routers provided by ISPs are dropping the voltage down to 3.3V for the internals. So the 5V works fine. But you're right, it wont work for every modem/router and some do require the higher voltage :)
Hi Gadget Addict. Great idea! Simple, cheap and works. I would like to contribute to your idea, with the suggestion of using a power bank with quick charge 2 or 3 capabilities, and connecting a quick charge trigger module in the USB port of the power bank. With this setup, you can configure the voltage the power bank deliver, from 3 volts to 12 volts.
Cool video to show off your power bank and router collection. Nice idea. I have my router on a UPS and the lead acid battery seems to be dead now so would need this alternative.
Brilliant! So these smaller power bricks have DC outputs, which is why you were cautioning us to check the voltage? And that's why you had to change the power cord to your modem/router to a USB to DC one, right? But I found ready made ones on Amazon, like this 3.28ft USB 5V to DC 12V Converter Step Up Voltage Converter Power Cable,for Camera, Desk lamp, Speakers, Blue Tooth Headset, and Other 5V Devices.(5.5 x 2.1mm). Wouldn't this do alright, provided 5V to 12V is what was needed? They had other similar cables and end pieces to fit any size DC. One last question: If I just used my Bluetti EB3A power station with UPS, and plugged into the AC outlet on it, I would accomplish the same thing, right? (Just not as inexpensively and cleverly as you.)
Unfortunately doest work on BT Hub 5 router or their Openreach modem :( ordered a RAVPower 27000mAh power bank with built in 220V AC Outlet, hopefully that'll work but it's costing me £180 :/
Did you try with a very short USB cable? I've found some routers only work with a 1-inch cable because of the voltage drop. And even then I had to use a cable with thick wires inside. Of course the other alternative is to buy a 5V to 12V USB cable which can be had for a few pounds and is generally much more reliable. The Rav will do the job, albeit at a higher price.
Weird, those numbers don't quite add up. 12V at 1.4A is 17W and 5V 2.4A is 12W. And I'm amazed to hear your BT router is consuming that much power.. incredible.
You said the output was 12V 1.4A and the input was 5V 2.4A. So that's 12W input with a 17W output. Many routers state a certain power input but often use much less. For example the one supplied by my ISP claims 12V 1A which is 12W but it actually consumes 3-4W.
tried this with Mi powerbank. On power outage, the powerbank stops for 1 second and then start powering my router - which is enough to reset the connection. Can help in this regard? I have Mi 10400 and it support pass through charging.
How do you know a power bank that can be charged when used? And also when there is light is there a way the power bank stopped working and starts using direct power?
Do you know the reason why most of them are rated in 12 and 9 volts if they can run at 5 volts? If there is no problem in running it in 5v for a long time then using 12v & 9v is a waste of energy.
I guess one benefit for the manufacturer is that they can use thinner wires on a 12v power supply, which saves money. Also the mass availability of AC to 12V DC converters probably drives down costs.
only tp-link and d-link routers are power hungry, they take 9v 600ma for running smoothly (in single power bank setup the lights were flickering and restarting continuously , --my router is tp link wrn841n-- ), i personally tested with 5v 2.1 amp (output) generic power bank for various router brands includes tenda, digisol, netgear etc all rated at 9v 600ma ,but they are working perfect with the single power bank setup. my query remains , will it work with a step up transformer from 5v to 12v circuit available at ebay . .?? any reply would be appriciable . .!! thanks
How does it work in the long term? Does it affect the functionalities of the router in, say, a few months or a year? I mean there must be a reason the routers say 12 V, isn't it?
i have limited electronics knowledge. Im sure my router is pretty power hungry (dual core wireless AC - Asus ac87u). from what I understand, i need to ensure that the wattage of my router is supported by powerbank right? if my router is 10watts, i need 2.4a 5v powerbank?
For sure there will be some hardcore routers that won't run (reliably) from a USB powerbank. I believe the average power consumption of the ac87u is ~10 watts and I think it uses a 19v power adapter. 10 watts at 5V would be 2A but you'd want to use a powerbank with a 2.4A output so you have some breathing room. But to be honest, I have a feeling it won't work at all since they chose to go the 19v route instead of 12v, there's likely something inside operating at a higher voltage. Unless they simply wanted to be able to use thinner cables due to the higher voltage. I have access to a friends ac87u, I can try it and let you know. I believe it also uses a different sized barrel jack than the standard.
Mmm I dunno if I can show more than what's in this video. Cut off the end of a USB cable and connect the red wire to the positive and the black wire to the negative of the DC jack. At least if you need a center positive cable like what I showed in this video :)
Neat. I actually have such a cable laying around that I was using to power a small LCD and driver board, correct polarity and short wires on top. I tested it with with a 802.11G Linksys router I had around, seemed to fire up fine. Though, sadly it doesn't seem to work with my Motorola NVG510 DSL modem/router, even plugged into a 2Amp output power bank output. Of course, that's what I actually need to power if I want internet for my laptop during a black-out. :/
it most certaily does not work with talk talk's super router! - This is so sensitive that it sometimes restarts itself if the supplied power supply drops out a little
you always have the nicest gadget (referring to usb watt meter 'cause I've been looking for a decent one for a long time) anw. where did you get or what do you exactly call that round adaptor? I'm definitely going to make this project. thanks for sharing this.
You can find the little connector by searching 'DC Barrel Jack terminal'. I can't remember where that specific watt meter came from. I think it's from eBay. The portapow advanced meter is still my fave.

Of course it will still need to trickle charge the cells now and then to keep them topped up. The specs listed on the sales page usually indicate if this is possible.
Gadget Addict so pretty much the 500 charge cycles won't be affected? Or the life span of a power bank doing this for a "fail safe" in case of power outage?
A charge cycle is a full discharge and recharge. Most of the time it will stay trickle charged from the AC. Provided you buy an appropriate powerbank, there should be no longevity issue.
Gadget Addict hmmm now to find a cheap pass trough charging power bank
for fibre routers and ONT you can get 2 USB to DC cables with a step up power module to convert the USB 5v to a proper 12v 2.1A input. Li-on power banks are cheaper than ever, I can buy a 60 000mah power bank with multiple USB and USB-C ports with passthrough charging and fast charge capabilities for about $65. In countries like mine where we lose power from 2 to 4hrs at a time multiple times a day this works wonders and is cheaper than router UPS options with a lot less capacity.
Hello. If my internet connection has no bundled telephone, I will not be able to use this trick? I am using skycable broadband internet. What are my options? I hope you can help me
been doing this for almost 2yrs. and it really works on my globe/prolink router
Thanks for sharing that :) I've had it going for just a couple of days but the principle is solid so I'm not surprised to hear it going for years :)
Gadget Addict i have 5 power bank, i use 1 dedicated to my router
john doe YOOBAO 10000MAH, napansin ko pag asus or mi powerbank gamit ko di stable ung internet
Works but only the modem turned on but it won't connect to the ips provider i think 5v is not enough to connect to the internet
I have a 12v Huawei Fibre router with a USB to DC cable running from my powerbank, but it does NOT work like in your video. Any suggestions???
When you undervolt a device it may try to use the same power, which is current times voltage. As a result, there might be 2 or 3 times the current going through the wires with 5V compared to 12V. Would be good to make sure the connectors and wires are good to go for higher amperage.
Hi, copied your procedure, modem turns on but no wifi (12v/1a)
I think your video is awesome.
I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously. However I want to be sure if it is actually pass through charger or is it just taking power from the battery and powering the router and then the power bank charging it self when the battery drops below 100. Pass through charging should simply connect the power input to the out of the power bank unit if the power bank itself is fully charged. If this doesn't happen then it will simply keep consuming battery cycles of the power bank as it will keep charging as soon as it drops below 100. Would like your views on this.
sir my problem is , i have to make a ups using power bank... i just used 5v to 12v step up module.for my router. connected it with power bank and using router continuously. but the problem is i cant use the power bank while connected through power outlet... there is switching issue happens.. while powers off and power on.. time... approx 2 second.... how to prevent that power bank behavior? i am using mi powerbank
Man,you just saved me soooo much money THANK YOU SO MUCH!!!!
yeah, true
*Is there a way to know if a power bank support pass through power?*
there must be a reason why these routers are rated as 12V and not 5V
have you tried this method with a router using all the Lan ports?
I have a question. When the powerbank is fully charged and it is still connected to the charger that is charging it, and the router is connected to the powerbank and switched on - in this scenario, does the router then end up drawing power from the current flowing in from the charger directly, and the battery in the powerbank is, well, inactive or something?
Phone line usually dead too 😔
Really? I've never experienced that. The telcos are required to have UPS and generators to keep those going.
how much time does a 10000mAh powerbank can give backup
Mat, you are just bloody easier then every one. Thank you
Are there any safety issues here? Ie. Leaving it plugged in with pass through on charge?
But doesn't the powerbank overheat?
I have two devices (Router and modem) how to use both of them on a power bank?
how are you powering up 12v routers with 5v usb, if really routers are happy with 5v, why not all of them just use 5v supply why 12v
most Power banks come with adaptive circuitry to support 5/9/12 v outputs by default depending on the load you plug in. Because most modern fast charging devices demand them.
thanks for the vid man was planning to buy a 5 to 12v step up cable then i came across your vid and my lte wifi modem worked fine
thenks a lot :) real helpfull keep up the good work :)
Cool idea and you don't have to butcher a USB cable or fiddle with an adapter at all. They make USB to DC cables, I actually bought one recently so I could charge my hand vacuum in my car with USB.
i have tried this....i used powerbank to power my zte 12v router but the problem is that only the red power light comes on and it doesnt go any further...need help
How about a link to buy the Moyou.
Risk of fire of powerbank used 24/7??
Can you confirm if all power banks that support pass though provide uninterrupted supply when main goes off ? Can you recommend brands which are uninterrupted regardless of power status changes ? I have 2 power banks xiaomi and another brand both interrupt output when main power status changes
Hi, 4 years later I believe you've gotten a good product.
Please i need recommendation from you as i want purchase a powerbank too
Hi, I want to use your router/powerbank trick but I dont know how to check the polarity so that I can connect the right wires. I only have a clamp meter 266 and I have already severed the wire of the adapter. Can you help me identify which is the load wire and which one is earth/neutral?
Dude's got enough battery's to power a city 😭😂😂😂
I did try this idea with my binatone 9v modem, the power bank powers the modem. Only the PWR and the Wi-Fi LED glow. Neither the ADSL nor the internet LED glows. I also tried by keeping the USB cable shorter, the modem powers on but the internet doesn't come. Any kind of work around you would want to suggest such as using a power booster? If yes, then which is that instrument and how?
There's the occasional modem that it won't work with. You can buy a boost converter on eBay which can increase the voltage to 9V. Have you tried a cable with thicker wires and a higher output USB charger/powerbank?
Thank you for your reply. I will try and will post back if further assistance is needed.
Had a question about the power bank ups suggested by you.
Is it a good idea to have this as a permanent solution? What are the chances of fire, due to continued charging of the power bank and the router? Have you used it for a long time and found any pointers that you can share. Thanks
Won't this damage the router in the long run?
also
If it requires a certain amount of power then with lower voltage the ampage will go up, won't that potentially burn the tiny USB wires?
no it will not damage your router has electric circute which prevent over volt and ampere and supply what router want
Does anyone have a link to buy the USB to router cable?
With 16000mAh power bank input 5V/2A, output 5V/2.1A and cable 2 meters long, the router boots up. But router keep rebooting once wifi is active. Is it because router is not getting enough power? How to fix this?
How much time would a 10amp powerbank will keep the router going?
Is a 10000ma enough for 2hr on fibre and router?
What i observe about this method is it might work 50/50. Imagine you have 12v light bulb powering 5v only. Youll never get that bright power output of 12v so there is a performance lost here. In this case using 5v only in 12v gadget. Yes led will work cause it uses low voltage but some components in board might not work properly. It doesnt mean led light up at 5v will perform 100% of system. Like what i said in some gadget this might work. Good review.
Thankfully most budget routers provided by ISPs are dropping the voltage down to 3.3V for the internals. So the 5V works fine. But you're right, it wont work for every modem/router and some do require the higher voltage :)
You're showing a video of already DYI but do recommend a power in the market that does the same.
You can find them on shopee, lazada, ebay, amazon etc. Just search for 12v usb cable.
Power rating of my Router is 12V - 2.5 A. Question is can i plug it to a USB with an output of 12V but only 1.5A? Thanks.
power outage only a couple of hours...where I am here in Australia, 18+ hours is pretty regular :(
Hi Gadget Addict. Great idea! Simple, cheap and works. I would like to contribute to your idea, with the suggestion of using a power bank with quick charge 2 or 3 capabilities, and connecting a quick charge trigger module in the USB port of the power bank. With this setup, you can configure the voltage the power bank deliver, from 3 volts to 12 volts.
Where I can buy this module?
how mach must we charge the ups?
After cutting the USB cable how would you know if which wire is the negative and positive? Thanks
Ideally you'd use a voltmeter/multimeter to check. But it's usually safe to assume red is positive and white/black is negative.
Ill be trying this one out. thanks for the reply, i appreciate it
long term review, did the battery pack last long? I think most of them uses the battery if the charging is not strong enough.
Cool video to show off your power bank and router collection. Nice idea. I have my router on a UPS and the lead acid battery seems to be dead now so would need this alternative.
Brilliant! So these smaller power bricks have DC outputs, which is why you were cautioning us to check the voltage? And that's why you had to change the power cord to your modem/router to a USB to DC one, right? But I found ready made ones on Amazon, like this 3.28ft USB 5V to DC 12V Converter Step Up Voltage Converter Power Cable,for Camera, Desk lamp, Speakers, Blue Tooth Headset, and Other 5V Devices.(5.5 x 2.1mm). Wouldn't this do alright, provided 5V to 12V is what was needed? They had other similar cables and end pieces to fit any size DC.
One last question: If I just used my Bluetti EB3A power station with UPS, and plugged into the AC outlet on it, I would accomplish the same thing, right? (Just not as inexpensively and cleverly as you.)
Unfortunately doest work on BT Hub 5 router or their Openreach modem :( ordered a RAVPower 27000mAh power bank with built in 220V AC Outlet, hopefully that'll work but it's costing me £180 :/
Did you try with a very short USB cable? I've found some routers only work with a 1-inch cable because of the voltage drop. And even then I had to use a cable with thick wires inside. Of course the other alternative is to buy a 5V to 12V USB cable which can be had for a few pounds and is generally much more reliable. The Rav will do the job, albeit at a higher price.
Gadget Addict I bought a USB 5v - 12v cable of Amazon, I tested the output with my multimeter and the outup was 12v but only 1.4 amps. Input 2.4 amps.
Weird, those numbers don't quite add up. 12V at 1.4A is 17W and 5V 2.4A is 12W. And I'm amazed to hear your BT router is consuming that much power.. incredible.
Why does it not add up? The plug says 12V=1500mA, the router is meant to be 9.2W.
You said the output was 12V 1.4A and the input was 5V 2.4A. So that's 12W input with a 17W output. Many routers state a certain power input but often use much less. For example the one supplied by my ISP claims 12V 1A which is 12W but it actually consumes 3-4W.
but what about the fiber box
tried this with Mi powerbank. On power outage, the powerbank stops for 1 second and then start powering my router - which is enough to reset the connection. Can help in this regard? I have Mi 10400 and it support pass through charging.
How do you know a power bank that can be charged when used? And also when there is light is there a way the power bank stopped working and starts using direct power?
Toyosi Adebola you must check that the power bank has pass-through charging feature.
Is there no problem with voltage? I mean the power bank is about 4 to 5 volt but router is 12.
You can go undervolt but the signal will be weaker
Does it work for fibre?
Was this shot in the Philippines? PLDT is a local ISP there.
Bright idea. But what if the powerbank has low mah and drain so fast
Do you know the reason why most of them are rated in 12 and 9 volts if they can run at 5 volts? If there is no problem in running it in 5v for a long time then using 12v & 9v is a waste of energy.
I guess one benefit for the manufacturer is that they can use thinner wires on a 12v power supply, which saves money. Also the mass availability of AC to 12V DC converters probably drives down costs.
only tp-link and d-link routers are power hungry, they take 9v 600ma for running smoothly (in single power bank setup the lights were flickering and restarting continuously , --my router is tp link wrn841n-- ), i personally tested with 5v 2.1 amp (output) generic power bank for various router brands includes tenda, digisol, netgear etc all rated at 9v 600ma ,but they are working perfect with the single power bank setup.
my query remains , will it work with a step up transformer from 5v to 12v circuit available at ebay . .??
any reply would be appriciable . .!!
thanks
My router is 12 volt and onu device is 5v is it possible tow run this two device equally with one power bank
This opens my mind to a whole new level :D thanks for this info man appreciated it
can i use my One power bank 5v
use my two router 9v and 12v together?
How does it work in the long term? Does it affect the functionalities of the router in, say, a few months or a year? I mean there must be a reason the routers say 12 V, isn't it?
Bro How about 12v but 3.0A?
hello, nice informative video. :) I would also like to know if its bad for powerbank to use passtrough to power a device 24/7 ?
Which powerbank has ups capability? ??
i have limited electronics knowledge. Im sure my router is pretty power hungry (dual core wireless AC - Asus ac87u). from what I understand, i need to ensure that the wattage of my router is supported by powerbank right? if my router is 10watts, i need 2.4a 5v powerbank?
For sure there will be some hardcore routers that won't run (reliably) from a USB powerbank. I believe the average power consumption of the ac87u is ~10 watts and I think it uses a 19v power adapter. 10 watts at 5V would be 2A but you'd want to use a powerbank with a 2.4A output so you have some breathing room. But to be honest, I have a feeling it won't work at all since they chose to go the 19v route instead of 12v, there's likely something inside operating at a higher voltage. Unless they simply wanted to be able to use thinner cables due to the higher voltage. I have access to a friends ac87u, I can try it and let you know. I believe it also uses a different sized barrel jack than the standard.
Gadget Addict that would be perfect!
Hey GA! will you make a video on how you make the cord?
Mmm I dunno if I can show more than what's in this video. Cut off the end of a USB cable and connect the red wire to the positive and the black wire to the negative of the DC jack. At least if you need a center positive cable like what I showed in this video :)
No Working in My Tenda D150 DSL WiFi router.... It need 9V.... USB booting up but DSL & WiFi not working
I tried it but i think i don't work for a 12v/2A modem. Any advice pls?
Isn't it dangerous to keep the power bank charging?🤔 Please enlighten me.
Rather, how would I know that the power bank supports pass through power?
Does this affect the speed of the internet
So, can this be used as a long term solution? If any, what component of the setup needs replacing?
There is 2 units, 1 router and 1 for wifi. Do I need 2 usb cord to connect it with my powerbank?
Neat. I actually have such a cable laying around that I was using to power a small LCD and driver board, correct polarity and short wires on top. I tested it with with a 802.11G Linksys router I had around, seemed to fire up fine. Though, sadly it doesn't seem to work with my Motorola NVG510 DSL modem/router, even plugged into a 2Amp output power bank output. Of course, that's what I actually need to power if I want internet for my laptop during a black-out. :/
it most certaily does not work with talk talk's super router! - This is so sensitive that it sometimes restarts itself if the supplied power supply drops out a little
you always have the nicest gadget (referring to usb watt meter 'cause I've been looking for a decent one for a long time) anw. where did you get or what do you exactly call that round adaptor? I'm definitely going to make this project. thanks for sharing this.
You can find the little connector by searching 'DC Barrel Jack terminal'. I can't remember where that specific watt meter came from. I think it's from eBay. The portapow advanced meter is still my fave.
Help, i bought usb to dc cable but its not working its like powerbank dont have that much Volt (5-A)
What should i do, please help
