- Is it possible to use a USB power bank as a UPS for your router, modem and other 12v equipment?
During a power outage, your phone line continues to work because your provider maintains a battery backup. You can continue to surf if you have a way of powering your modem/router.
I tested several wifi routers, modems and a networking switch and all of them operated perfectly fine with a 5v input from a USB battery bank.
During a power outage, you can manually swap from the AC power supply to your USB powerbank supply or you can buy a powerbank which supports pass through charging and leave it permantly attached to an AC USB charger.
With a power bank that supports pass through power, the powerbank will be charged at the same time as outputting power for your modem. When the power goes out, the modem will operate purely from the powerbank and when the AC comes back, the powerbank will begin charging again. All of this works with no interupttion to your internet connection.
It's important to pay attention to the polarity of the connector. All of my devices have a positive center pin. But you may come across a device that has swapped them around.

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
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 !
Most of expensive ones does not allow Pass Through either as they claim it destroys your power bank quicker due to recharging cycles.
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
Almost 4 years and I found this to be a comprehensive video. I will try this thank you.
This man has a lot of power banks!
excellent i was searching for this type of solution from last few months and was ending up with big UPS, but this compact and smart idea is very great, thanks alot dear
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)
I needed something like this to save me some money on keeping my router plugged in all the time.
Use 12v ups battery
@@ankitpal9761 It is very expensive
there are usb converters thingys that you can buy that goes from usb 5v to the 12v barrel connector, it increases the voltage
idot
Dude's got enough battery's to power a city 😭😂😂😂
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
Works as mentioned.... Critically needed this during the lockdown time when i have to continuously work from home and internet used to go down during power fluctuation...Thanks..
I see u have commented a year ago did u use this routinely? How was the experience?
Below was concern about using this method
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.

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.
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 ?
I have a surplus of those Jack adapters from a rejected CCTV project. you are giving me ideas.
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 $65. In countries like mine where we lose power from 2 to 4hrs at a time multiple times a day this works wonders and is cheaper than router UPS options with a lot less capacity.
thanks a lot you just saved me from paying 50$ , 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
I also suggest you that If your device is not working properly with 5V, try to find a step-up converter and set the voltage that your device needs.
100% works. Thanks a lot bro making this video. Really useful 10 out of 10. Hats off to u❤️❤️❤️❤️❤️❤️❤️❤️
Hi please i need a recommendation of a pass through power bank,
Which one are you using thanks.
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.
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
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
Man,you just saved me soooo much money THANK YOU SO MUCH!!!!
yeah, true
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 it works with only below 12v 1a routers not new 5g/AC dual band 12v 2a routers
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.
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.
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.
Where I can buy this module?
Mat, you are just bloody easier then every one. Thank you
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.)
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
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 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.
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
Hello,
Very interesting idea/solution. One question to check, which Powerbank do you suggest? 10000 mAh Li-Polymer is okay? And is there any risk using it as permanent option? I mean if we connect it between power source and router for longer times? Please clarify.
Thanks again for you nice video...
How about a link to buy the Moyou.
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
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 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.
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.
Gadget Addict Great video 🖒🖒🖒🖒🖒. What Powerbank do you reccomend as I'm using a PLDT Fibr Modem DC 12V/2A? After watching I tried it but it's not working. I am using Royqueen Powerbank 20,000 Mah and it's working charging my phone the same time charging my powerbank.
Gadget Addict hey i was able to power up my modem with this method at full bar for the first time but suddenly my modem's indicator shows 1 bar only....looks like it doesn't have sufficient power 😅...what should I do?
I'm using YES Zoom 4g (input : 12v, 1.5A)
does power loss a lot if your cable is too long? like half a meter?
@@59977012 have you had a solution with a modem with 12V/2A also tried it and its not working. I saw someone using 2 powerbanks, but i haven't tried it yet
i think its not working cause the modem is 12V 1.5A-2A.. and the powerbank is only 5V .. i think the usb cable its produce 12V output.. and not 5V
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
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
yup i actually used a laptop battery 10 volts to power our internet modem 12v..& it works.. but the problem is our internet provider server no electricity too... useless & i dont know why they dont have a back up power.. very dissapointing..
I bought a step up cable 5v to 12v,1A isn't working on my Huawei b315 LTE router
I have power bank, Which is better for Fiber Optic router 12v or 24v power supply ❓
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. :/
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.
Thanks seems you are in the Philippines too im in Palawan and have been trying to get something and this looks perfect. I looked into the UPS but I didnt think it would last that long. They sell on Lazada for about 1700. Ill look for this thanks!
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
Hi the router uses 12v the power bank can only supply 5v wont this make my connection or internet slower
hello, nice informative video. :) I would also like to know if its bad for powerbank to use passtrough to power a device 24/7 ?
This opens my mind to a whole new level :D thanks for this info man appreciated it
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
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?
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.
long term review, did the battery pack last long? I think most of them uses the battery if the charging is not strong enough.
Does this affect the speed of the internet
Brilliant.
Thank you so much for this.
Simple and effective.
awesome Tip mate , Thanks for sharing this Knowledge
You have the biggest collection of modems and power banks I’ve ever seen 😄👍. Great info, thanks man 👍👍
how much time does a 10000mAh powerbank can give backup
Are there any safety issues here? Ie. Leaving it plugged in with pass through on charge?
*Is there a way to know if a power bank support pass through power?*
Hi, copied your procedure, modem turns on but no wifi (12v/1a)
You can go undervolt but the signal will be weaker
GA great video, I can use this in Catbalogan, the Brgy on Buri Island we have brown outs a lot for 6-8 hrs, Thank for sharing.
You're welcome :) You're really having a GA binge watching session haha :D
Yes I'm catching up as your videos are awesome and very informative. :P
Buri with dead airport.. damo magdate didto paggabi na..
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?
Your router is very low power then. Most routers tend to take about 10W, so your powerbank would have to handle 2A up and down - not every powerbank can do that. Good idea in theory and in rare practical cases, but it's not as easy as you make it seem.
Bright idea. But what if the powerbank has low mah and drain so fast
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???
Hi. Nice video.
Is there any way (or any circuit) to make a 'by-pass thing' to avoid the powerbank to function 24/7 and only work when power is off?.
Yeah same question here!! good video though
power outage only a couple of hours...where I am here in Australia, 18+ hours is pretty regular :(
hi, does all moyou brand supports pass through power? What model did you used on this video? Is it safe to plug it 24/7? I would like to use this to power my raspberry pi. Hope you can give me some insight.
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?
Thank you man !!! Detailed ,very good
This is a life saver. Thank your for this.
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?
But doesn't the powerbank overheat?
Risk of fire of powerbank used 24/7??
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 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?
The reason the 5v in 12v router works is a lot of routers actually run internally at 5 or 3.3 volts and use some kind of simple voltage regulator to bring the 12v down.
However, you may see some stability issues if the provided power is not quite sufficient, wifi radios are power hungry and may make the power bank's output sag.
Indeed :) So far I've not seen any problem operating the basic ISP provided modem/router combos, even under reasonable wifi load. Even my $2 powerbank seems to manage it okay. Although personally I'm using a good quality powerbank with 2A output to replace the lead-acid battery UPS that I showed in this video.
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.
I have this for long years, but in my village if I haven't power in house, also I haven't internet connection.
Really helpful video. I want to try this for my modem as well as cardless phone. What happens if i swap positive and negative by mistake? will it damage my modem or it simply does not boot until i connect it correctly? Please advise. I do not want to loose my modem.
+Kishore if you get the polarity wrong, you could damage your modem.
I have a power bank and now i bought the Internet SIM from one company Internet which supply service internet. and actually this SIM must put into the Router but i need to put into my Power Bank instead. So is it possible for this case ?
i dont think you need too proove soo much you haveallready done enought thanks again
hey bro nice video but i have a small problem is when u connect both port in and out simultaneously there is any battery problem beacuse when batterys are charging it is not gud to use simultaneously please help me out from this problem thanks..
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 :)
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.
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.
Gadget Addict hmmm now to find a cheap pass trough charging power bank
This is very clever Gadget Addict.Can one buy a 12v/usb cable or is it a diy cable only?TIA
I'm glad you like it :) You can find a pre-made cable on Amazon and eBay by searching '2.1mm USB cable'. Here's an example on Amazon UK - www.amazon.co.uk/GA/dp/B00SCBAE00
Awesome,thanks for the info.
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.
I have two devices (Router and modem) how to use both of them on a power bank?
Extremely Good Video!!
but what about the fiber box
Also mind current consumption as well as requirement of your router and also keep in mind how much can your powerbank deliver.
Was this shot in the Philippines? PLDT is a local ISP there.
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
Is a 10000ma enough for 2hr on fibre and router?
Does it work for fibre?
