- My take on the rumours thoughts that the Anker 737 power bank has a hugely limited lifespan compared to other batteries out there.

After putting out a video on the Anker 737 back in August 2022, I received the same comment quite a few times. People seem to believe that this power bank is completely useless after 300 charges.
I am personally unable to find any solid evidence of this online. As with so many things on the internet, speculation and rumour spread like wildfire, with a question from one person becoming a statement of fact by the next.
So I thought I would add to this by giving you my take on it as a user of the Anker 737 and someone with an opinion and the ability to make an educated guess.

One question I didn't get answered from your video.
Does it come with it's own UK compatible power brick?
No, at 300 cycles, it should be at 80%. lifep04 battery have well over 3k before 80%.
I have power Banks from anker that are 5 to 7 years old and they still work perfectly fine
As a small child, I heard from an adult that houses were built to last 100 years. From this, I concluded that the second the house reached 100 years, it would immediately collapse, with the inhabitants inside.
That's how they make lightbulb nowadays
I work in the car industry and some customer told me, "they can build older semitrucks to last a million miles but you think that exist now?"
Later everyone went the vw route and started making their parts out of plastic...
Plastic intake manifolds, plastic valve covers, etc.
And having the 2.0 liter turbo engine has the holy grace of power and fuel consumption.
VW had veen doing that since 2005
Harley Davidson has also been doing the european treatment for years making their bikes harder to work on
If its popular, theirs some millionaire douche wanting to make the most profit iff it
Why do you think most car dealerships charges over 150$ an hour for Labor, that car is made for you to come back in and spend more 💰 😉
I just bought one. This life cycle isn't bad at all. Also, after 3-5 years, I'd probably want the latest technology that would have been developed by then anyway.
Exactly. Things move on quickly. I think people get a kind of 'range anxiety' when it comes to this sort of stuff.
Well I love my eb3a with 2500 cycles but you certainly don't want to carry it in your backpack every day 😂😂
@@rickandmorty4-ever61years ago we have Nickel-Cadmium. Then to litium-polymer. To lithium-ion. Now we have Gan technology.
And years ago we don't have fast charging, wireless charging. USB C
@@rickandmorty4-ever61 Just a few years ago you'd call a powerbank fast or powerfull if it could output 2x10W or charge with 10W via Micro-USB. Now the new Anker Prime Powerbank can output 250W and charge with 170W over USB-C. It may not be a big step from 20W to 250W for all people, but i wouldn't say nothing changed
@@rickandmorty4-ever61it has, by a lot.
Thanks for posting this - as it was the video that finally put me over the edge to just get this backup battery! I've had some anker battery banks for 7-8 years now and while they still work fine, I need to upgrade to a USB-C setup!
I have been using 18650 battery's for 6 years now, still working great, all of them have no problems, They have been heavily used..... And i have old anker power banks from 5 years ago, still working well....
I've had Anker batteries I've bought in 2014 lasting up to 5-6 years. The issues that start to arise is the following: LED indicator saying how much battery is left stops working, it just cannot be charged anymore, it will charge but not discharge and the last culprit is that it will charge for 5 minutes and then suddenly stop even though the battery still has juice.
I had that same problem. I'm thinking of throwing it away and buying new one. It has served it purpose
That's what I;'ve done as well. I bought the Powerhouse II for when I'm out of my car and purchased their Anker 737 for when I'm out on long forages through the forest @@legendisme8693
it's chinese shit man, for the price it should last 15 years
I've had an Anker power core 20100 in regular use since 2017, with no noticeable drop in capacity. I ran a dash cam with it for months as well. It's a workhorse powerbank.
How did you took care of it?
I don't. I just use it. Charge it up when it's flat. If anything I just charge it slowly.
@@MyOnlyCommentIsI use mine at work and drop it a lot from high areas since I climb stuff sometimes, been a year and it still works great although it’s all scratched from dropping it. Love the product overall
I wish people will actually get a course in batteries and technology or something. Because 80% of the people out there or 85% of the people don't really know what they're talking about. This guy has a great.
Understanding of understanding of batteries. I've worked in cellular for 10 years. Dealing with the battery's reconditioning batteries. Sell on cell phones and working in wireless and being a trade engineer. This guy explains it quite well. I don't mean to be rude to people, but Jesus, come on. People stop panicking most of you will never even getting or meet, reach a full potential and using this device, you probably would drop and break it, or you'll lose it or something like that before you have even reached 300 cycles.
Great video with great information. I just got 2 of these batteries recently myself with a Black Friday deal. I've already got almost 1000wh on them because I mainly use them to power my laptop during peak rates here in California (about 30wh/hr). I am trying to extend their lifespan by utilizing 80-40% (because it is convenient for me to do so). Tempted to get the next generation of this battery that allows control with bluetooth but I'm going to hold onto these for a few years at the very least. I've been using Anker batteries for years and years, usually donating them to family/friends who then use them for many more years.
I just bought one myself and realized myself the 300 cycles. I knew of how the cycles worked on a battery but still was a little concerned. After watching your video it made me realize the biggest reason I got mine. And that was as a battery backup for my ROG Ally. (I've got plenty of lower power delivery battery banks for my other devices). But the use would be: if I'm ever a passenger going on a long trip and won't have access to a inverter in a car (not very often), a power outage (which happens more often then long trips but still not very often.) A camping trip (which is about as likely to happen as will). So the use will probably last me years. I still have an old Anker 20k mah 3x a-port with power iq bank that charges but the display is dead and another Anker 13k mah 2-a port with power iq that works fine for my other devices. I'm excited to get this battery bank and after watching your video it made me sit and realize that I, like others where probably zeroing in on that 300 cycle part just a little too much. There's nothing to worry about. :)
How long does it take to charge your rog ally to full, or do you use while playing it?
hi, friend. You still have it, how many more cycles did you get out of it after those 300 cycles? How long did those 300 cycles last? And I also wanted to know if you charged it almost every day?
i like this guy presenting style, it felt like top gear
True ✔️
Haha, Nah Fr
Depending on the specific duty cycle, results will vary. The trickle setting or only running the pack down to 50% before a recharge. It will last significantly longer. It comes down to stress and dendrite growth between the anodes and cathodes.
I've been using mine for 2-3 months, and it is only at 3 cycles. So if I guess this is going to last 30 years then it is not too bad...
Hello friend, how are you . When you published this, did you use them every day? And I wanted to know if you still have it and how it has hurt you and how many cycles has it taken?
I mean... your typical li-ion cell has a rated life of about 500 cycles, though that's usually quite conservative (80% of original capacity) compared to what most people will be OK with (closer to 50%, probably). Unless you reverse-charge them, they don't just quit on you, rather they gradually become useless.
Given the rated continuous load on that thing (which equates to over 6A per cell, if their marketing diagrams are to be believed), a reduced rated cycle life is not surprising in the least. I'm not sure what type of li-ion cell they're using, but it'd make sense if they're high-drain IMR cells, which would also have the 300 cycle rated life. That's the price we pay for being able to draw 140W from the thing. Probably best to stick to smaller loads, if longevity is a concern.
Mine is at 84 cycles right now and still rock solid at 100% battery health
Rav power 20,000 have performed well also I have 2 of them. One in 2018-19 still going strong. Powers off when not touched but still charges in trickle mode
sucks they got banned
My experience with their 20.000 has been that the capacity is down the drain after 3 years.
I can charge my iPhone 2.5 times with it.
Very interesting. Thanks. I have two of these. Love them.
Same here, got one, had to get another :D. Justified it by giving away several of my older Anker batteries. .
You're forgetting another big factor though, batteries have a shelf life too cycles is just one factor for longevity. The state of charge is another an power-banks are a backup form of power so they almost always sit at 100% the most stressed state.
Hence you probably expect 2-3 years before the battery degrades to 80% regardless of the cycles. This isn't just Anker but lithium ion batteries in general.
We're on vacation and now it's broken. The display is black and doesn't do anything anymore. It was only charged with an Anker 45W charger. I love the display on the Anker 737 but will probably never buy such an expensive power bank again. And Anker's service is absolutely bad. They have a list of questions where the back and forth takes a week.
Any update on this power bank? I just got mine last week and charged it with an Anker 736 100w and after only 1 cycle my battery health dropped to 99% from 100%. Is this normal? I feel like I got a defective one. In one recharge it can’t lose health already… might contact Anker. Let me know what you recommend please. Thanks in advance!
After three cycles I’m at 98% this is worrying me it’s almost like I can only recharge it 100 times
Thank you! This is both reassuring and informative!
Really well made and informed video - kudos and cheers!
300 cycles? All you have to do is never let it run empty and charge it up to 85% and you'll be fine.
Will be back in a few years for the "replace batteries and reset charging cycles" video
I bought one a year ago and use it for EVERYTHING and charge it a lot yet I’ve only used 10 KWHs and 113 charge cycles
It’s normal for any battery that it will lose capacity over time while being used. I‘ve a 125 Ah LiFePo solar battery with detailed stats readable via Bluetooth and it started losing capacity ever so slightly over time. After 40+ cycles it has approximately 124,3 Ah left.
To reach 80 % SoC will take a while. Same with the Anker powerbank. And if some of the safety features will kick in, it would actually be a good thing! Does it have a hard lock at 80 %? Can‘t say yet, but I doubt it. Anker would need very good safety reasons to do something like that. In the EU there are regulations against deliberate obsolescence of products - and the fines are high for companies that disregard this. Anker as a renown brand probably don‘t want to risk it.
I think some people just don’t understand that batteries are consumables. Same as such things like tires, brake pads, wiper blades, and so on. They simply can’t be designed to last forever because of how they function.
Very true but exactly as with tyres (I'll go with the British spelling), brake pads etc, they vary enormously in quality. I guess I would personally expect better than 300 cycles from batteries in a device like this.
Battery banks of the price this one goes for should use the highest quality battery cells and honestly it should come with a 10 or 20 watt charging port for those times you dont need to charge it super fast but wanna help maintain the battery health a bit@@tdcattech
A lithium ion cycle is also considered full discharge and recharge. If you can keep your cycles from 100 to 60 and recharge you will get much more life. 80 to 50 to 80 is the most ideal for a these batteries but I mean we are here to use them not baby them.
In comparison, normal battery life for Macbooks is around 400-500 cycles. I've replaced 3 batteries on my MBPs over the years and found that 400 cycles equates to over 5 years of use. Usage of this device will be more intesive so I would expect 2-3 years of life should you use it regularly. So about $40/yr. Not bad.
If this is rated like other power banks, the cycle count is to 80% capacity which just means after 300 cycles, it’s only at 20% less capacity.
It would be pretty poor from a sustainability standpoint as well as customer satisfaction to physically limit a device. I'm sure you're right that it's just some 21700 cells being well used. I've just checked my device and I'm only up to 70 cycles. 🙂
Thank you Todd, was thinking the same.
300 charge cycles is about typical for most rechargeable batteries. Li-Ion do a bit better (I have a Mophie that is now about 8 years old and holds about 80% of it's original capacity, but I don't know how many times I've recharged it though, and it spend about 6 months unused). The only reason I now have to get rid of it is is the battery is starting to swell (no longer sits flat) otherwise I'd keep it, but it's kind of dangerous to use with a swelling battery obviously. Paid about $150 for that one (it was a 20,000 Mah charger with 3 USB-A ports -- no USB-C) but still think I got my money's worth out of it. Hopefully these Anker batteries will do the same.
But 300 charge cycle is about normal. If you charge it say twice per week from fully dead, I mean that's still about 3 years of use (104 charge cycles per year). That's probably pretty aggressive usage IMO, and most people might only recharge it once a week if that, unless they're using it to contasntly charge multiple devices each day or week, and running it down, but even at 100 charge cycles per year, it's not too bad, and probably is still better value than a cheap one that lasts only 6 months and then starts to have charging issues.
My experience is that for most people, 300 charge cycles on anything will be more than you think, unless you routinely run down your battery every 2-3 days, which some people might, but most people won't, and that those numbers are probably worst case. You may get 350 or 400 charge cycles out of it. The other key is how you charge it. If you charge it when it's 80% full, you're wasting charge cycles in some cases, but if you also run it down to 0% then you're also going to put more strain on it and it may only get 300 charge cycles, but if you do what most people recommend with Li-Ion and recharge when the capacity is between 20-60% then you should get the maximum life out of it that you can, whether that's only 300 cycles or more (probably more). I've seen that some of these power banks and charge themselves while powering something else and while you can still do that, that may also decrease the recharge cycle too, so I would not advise doing that if you want the maximum number of charge cycles. It likely doesn't have a huge impact on overall charge cycles, but not something I would do regularly myself. I would probably just do what I mentioned and let it run down to 20-60% before recharging. Obviously running it down below 20% on occasions likely isn't going to harm much either, but routinely doing that will decrease the life of the battery overall. But even my Samsung Galaxy S10 has managed to survive 5 years of me letting it run down to 20% or less and powering off, and it still holds a decent charge (enough for 1 day at least) now 5 years later, and that's the original battery it had when it was new (5 years ago).
I got the 250 watt it’s a wonderful addition to the power bank collection
Is that the new line? Yes, I might take a look at one of those.
@@tdcattech currently shipping in a few weeks/months from anker, do it!!!!! Lol
Thank you for the video. It’s excellent and I’m happy that I learned that today.
I trust anker porducts.. i order anker 737 its look nice and good for outdoor use
I am still using the old anker 26800mah that charges by micro usb.
It last long because high capacity to low capacity devices , less battery stress. Im out and about almost everyday. Charges my phone twice(3300mah) still have 75% left. I rarely push it to below 25%.
Yeah, I use one of those. Great power bank. Slow to charge but it's fine if you're vaguely organised and just put it on overnight.
Yes! The dual micro usb charge still works on mine and it even spent the night in 3 inches of water (on accident) this happened years ago and I still use it to this day. Plenty of drops too, it’s a tank.
Its not hard limited.
Every powerbank will slow over time. The data on display is awesome to see.
Have you hit that limit already and gone over?
According to the spec sheet for the cells, it can retain 60% capacity after 300 cycles when charging at 1.5C to 4.2V with .1Amp cutoff (Full) and discharging at a whopping 8C (discharging the entire battery in about 7 minutes) down to 2.5V (empty).
Keep in mind that a lithium ion battery is still useful even below 50% capacity remaining. Also know that this type of usage is no where near real world for this battery bank with these cells, only discharging at my estimated average of 2C continuous assuming you always use 140W discharge.
Assuming you do slow charging (5 hours) and discharge at about 80-100W the spec sheet claims greater than or equal to 80% capacity remaining after 300 cycles. So yes you can get more than 300 cycles with over 80% capacity remaining if you don’t leave it fully charged for more than 15 minutes. You might even be able to push 500 cycles if you rarely charge to over 80%.
The capacity it retains after 300 cycles is a good thing to include and doesn't matter what it is, should be listed and other brands not listing it just makes anker look bad I suppose
@@rokiedecentra9656 not really. You still need a lot of context to determine remaining capacity. How long you leave a battery full, how fast you charge and discharge and many other factors can give you 50% after 300 cycles to 70% after 1000 cycles for the same lithium ion cell. Sometimes cell manufacturers don’t even have all that information publicly available.
Even if a brand lists capacity after so many cycles, they can still claim using long life usage characteristics not representative of real world usage.
It would be more ideal for a brand to provide the spec sheet and the consumer determines what kind of cycle life they can expect with their usage.
@@battery_wattage i just noticed your username..... well many powerbanks actively hide the Wh rating so i dont have faith in them sharing that much info but yeah i also want them to be more transparent
The information about how many times the display was turned on give me more anxiety that the cycle of the cells. :P
Same😂😂😂
Mine stopped working at just 1 Cycle. Yeah, 1. I used it at over 100W power discharge for my laptop and charged it at 65W. and it just started failing to take a charge. It triggered Undervoltage alarm and would not charge, but kept discharging fine until it completely drained. Now it is completely dead and useless. So... I think we should be more worried about the circuit design than the cells lifespan here. I am blown away from the fact that this kind of failure came from a +120€ powerbank.
Funny you should say that. I have a video coming out today or tomorrow on the Anker Prime 200W which failed while I was filming some testing. I had to send it back.
Very informative. Thanks mate! 👍
Maybe a stupid question, but, why do you use a power bank? I mean, why not just plug your devices into the electric socket? Or, charge in the car, or when you get to a hotel when on trips? Just curious?
Is that really a serious question? You do realize some people go on long trips or hikes or maybe even camp somewhere. Literally lots of scenarios where you don't always have access to a wall socket or a car charger...
mine died just into the summer 3 months after I bought it.... Dont Buy Anker 737 Power bank.
Did they honor there 24 month warranty? Ove heard gpod things about there customer service.
Mines lasted over a year and I’ve dropped it from heights of 6ft plus numerous times while at work. Screen scratched up and battery health down only 3% but still works like a champ
Where is your warranty?
I doubt it's hard limited. I doubt it would go wrong after 300 cycles, other than it won't perform as rated anymore. That's why they say not to use it after 300 cycles are up.
I'm at 149 cycles on my Anker 737 and battery health is 94%. 12995wh total input, 12894wh total output. I usually charge it with a Dell 100w laptop charger and it's used to charge phones (maybe 15w output?)
One question I have is if it's a standard 18650 can I not just switch the batteries for new ones later?
Mine got zero cycles. :)
It arrived dead, would not charge....
I contacted support and they said they'd send me a solution by email and I never heard back.
I just did an amazon return on it.
So I think I got the record...
That’s good knowledge and it should be shared. Ty 😊
I have upgraded with a pair of these after many years (very pre covid) with a pair of "dumb" Anker powerbanks. I am not a power user and also do not need to charge the powerbanks at anywhere near the maximum capacity stated. My existing powerbanks have been passed on to grateful family kembers.
I charge an android tablet, an android phone and a Garmin smartwatch using the powerbank. I only bought these because 1, I am very happy with my Anker products (I have a larger pack with 2 240v sockets built in for camping with a solar panel, and two pocketable lipstick style packs too) and 2, having state of charge and charge rate info on the screen is incredibly useful.
The internet is definitely the place for stupid peopke to make ridiculous claims and hatch incredulous conspiracy theories. The tiring bit is that it takes longer and longer to filter out the chaff.
I prefer to buy quality. It tends to be better at what it is supposed to do and is usually far more reliable. And if it breaks the companies are generally better at dealing with these issues.
Also there is an option to open the unit and have the cells replaced new. Whether it’s done on your own accord or by a reputable repair facility
I'll come back to this video when mine reaches 300 cycles and ill let you know
@XXCV1 yes it doed
@XXCV1 does
Update?
@@Momosexual sorry to keep you waiting but im only at 175 cycles at the moment
One last thing to mention always discharging constantly at 140w is probably not ideal for the cells and also charging at 140w is not ideal either if you can use 60w pd charger it will be much better for the long term life.
i have a power bank with 10000mah from like 7 years ago still runs good. really thinking of getting this one.
Yea I got 7 years old anker 10k, still working just fine. I bought this one because I believe I will get same quality products that will last as long if not more
Don’t store it at 100% and try to not discharge it below 10%. Try to store it at 80%. Tesla know how to look after 18650 cells and they do this. Their warranty on these packs is 8 years. If you can’t get 10 years from this which is not working nearly as hard as a car…. Then there’s an issue.
I wanted to get shargeek storm 2 but I heard their customer support sucks compared to ankler, and that Ankle 737 is better in terms of specs. If I were to experience any issues, I can send the ankler over to their store in my country, whereas for Storm 2 I need to pay for the delivery to the US if I need to return it (that is only if shargeek agreed to the return, I read that they don’t reply to customer after awhile).
Battery counter in tech product just give me range anxiety
My old 2016 macbook pro already in 5000+ cycles
But the battery is still fine, yes it doesn't has long standby time anymore
But it still usable
And they add battery health in iOS
My phone on 75% now. And it said 'battery poor'
Yes I charge it more frequently but I can still use it for my daily driver
Now I never open battery setting anymore
That’s good enough for me
excellent video
Remember our cell phones after four years dont charge hold a charge so well and also our car batteries will sometime be completely dead and we change those and those cost much more.
thank you for this video :)
If you really wanted too, those 18650s are extremely ubiquitous, so long as there isn't a soft lockout, you could probably replace those batteries. Provided you can open the thing without damaging the case or electronics
This battery actually use 2170 cells.
My 2017 20100mah anker is still working well!
You are really a good product reviewer
The Anker power core 20100 is great had it for nearly 10 years still running like it was the first time I got it probably batteries are now shorter from age but not noticeable
Excellent commentary
Mine is damaged after a year of use. After about six months months of use, it jumps from 50% to 0% and then one day I plugged it in to my Samsung 45w charger and it started popping and smoking. Never touched it back.
You get 300 full cycles from Panasonic or Samsung premium Li-Ion cells, if their temperature never exceeds 25 °C.
I doubt Anker uses premium cells. They spend way too much on advertising...
For everyday use that’s kinda true. For users who use it to charge laptops at 100W the scenario isn’t that nice(and also temperatures). Plus if you re using even 60W charger it still gets a little bit hot. And it causes to charge it every day. By that speculation, for a heavy user it won’t have even 80% SoC after one year
My 737 just fried my 45w samsung charger and my anker charger, luckily anker is replacing both chargers and my 737 but still kinda scary that it suddenly started killing my wall chargers
How
Bro didn't came with facts, bro came with a story
Very useful to know. Thank you.
Great video brother thanks
Damn now I want one
The 300 cycle life is only put out by Anker for liability purposes, it will still function after that. People seem to worry over nothing.
Mine just hit 50 cycles today still going strong.
Thought for sure those cells 21700 series.
what would be a good industry standard of delivering Watts to laptops at 65?
Thanks a lot
This is intresting. My powerbank shows 95% battery health after 27 cycles. I use Anker Nano II 65W for charging. What could be wrong?
Сколько сейчас показывает? Проблема решилась?
300 to 500 cycles? That’s pitiful.
I have two 18650 powered devices that have well over 1000 cycles in 6 years and they’re still going fairly strong.
What brand?
@@DoomTrooper710 LG, LGABHG21865. But now that I look up the spec sheet they are only rated for 300 cycles... Weird, I must have gotten some unicorn batteries.
Anker 737 uses 21700 batteries! Not 18650!
It does. I realised that after recording.
@@tdcattech i bought 4 power banks with about 25.000 mAh capacity and tested them well:
1. Anker 737 (24.000 6*4000 21700) with a consistent above 72 Wh actual capacity - and a great charging time;
2. Cuktech (25.000 5*5000 21700) with an average of 70,9 Wh delivered energy.
3. Inui (25.000) - best in class, but doesn’t change the steam deck;
4. Charmast (23800) - the worst…
But if I only need to recharge it once a week, worst case is 300 weeks, or nearly 6 years. But, I know my requirements for this device - at least at this point in time - so let's say I recharge it every 2 weeks. You get the idea. So unless I have catastrophic problem with this device, it may be the last bank I need, as I'm 67 now.
Remind me to ask "Does it still work?" in 2 years (because of mandatory 2-year warranty in Europe) 😄
It already comes with a two year warranty from Anker...

Could you post an update on this please? (if you haven't already, and i just can't find it!)
What happens is one cell goes bad and unit will shut down. When the voltage drops they don't allow charging I've found.
is there way to count charging cycles in other power bank brands.ex: Mi
I have the anker 747 haven’t used it for couple months went back to it and it not working
Mine is on 25 cycles and I bought it two years ago and when it gets to around 20% remaining, it'll bootloop and won't charge anything until its charged back up again. I dunno what happened to it. But it's a bit strange
Jackery explorer 100 plus, 2k cicles 120 euros, 128w delivery, lifepo4, the best solution for the money miles away from the rest.
If it's easy to remove the case, I'll replace the batteries, which I always do
If you intend to spot weld in new batteries, I’d probably go with the shargeek options. This is glue together and will likely break, the shark geek just has 4 screws.
hello, I have this powerbank and a macbook pro 16 from 2021 and an asus rog strix g15 and now the question is why this powerbank charges these laptops with me up to 50w if this powerbank has 140 of them?
Depends on how much power the laptop can take over the USB-C power delivery cable. Some are limited to 60W which is absolutely fine for almost all tasks. It also depends on the cable used as not all cables will support 140W, 200W etc.
I used a safe solution for the powerbank, so since they added it to the 140w powerbank, it should do the trick
how many cycles have you used to date?
what's the actual state of your
anker 737❓
Mine had 75 cycles before showing battery health of 5%. Although anker is honoring its warranty on the device
Failures will always occur I guess. Good to hear Anker customer service is working. Makes a change from many companies.
I'm getting a UVP warning and ot shutdown off. Can only use it as a passthrough if it is plugged in.
Dead cell in the pack most likely triggering UVP. The charge puts the cell up to normal voltage but the second you remove the charge current the voltage drops.
Espero que esta powerbank sea mejor que la basura del anker 737 26k que tenia una falla en las baterias LG. Fue buena bateria pero con un error fatal, fuera de que no estaba bien aseguradas las baterias y se desconectaban.
I mean, even if it was only 300 cycles then it just stops, you still get alot out of that for the price imo. Its 24 000 mAh, which means if you exclusively use it to charge your phone every day you get about a week worth of it, meaning 300 cycles = 6 years of life. If you use it to fully recharge a laptop once a day, its going to last about a year before you run into issues, but realistically noone does that every single day. If you were to completely empty it out and recharge it every single day, you obviously must have access to a wall outlet right? And of course, if you are such a heavy user that you use your power bank THIS much, chances are you have several and likely replace them more often than every 6 years anyway.
Now of course this isnt even the case, its just the worst case scenario which isnt even unreasonable. The standard for lifetime of batteries like this is the amount of cycles it can take before the cells are at 80% health. So even after you 300 cycles and 6 years of every day use, you still have 80% of the capacity left. It doesnt just stop working unless theres a catastrophic failure, it just degrades over time. And hey, thats if you are unlucky. Maybe you get lucky and you get 500 cycles before it reaches that point instead? Thats well over 9 years!
Yeah no this is a silly complaint imo. The only thing I hate about this power bank is that its very misleading that they plaster "140W" all over it since thats the rate it can take a charge, not its output and at least to me its the output that matters. The 18w this pumps out isnt nearly enough to charge my laptop while using it, which is what I mainly use power banks for.
