How Long Will It Last? – Anker 737 Power Bank
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.

Does it has a pass-through?
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 died after 8 cycles lol.
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.
I bought this power bank less then a year ago , put on 129 battery cycle and my battery health dropped to a 5% , now i dont abuse it but for god’s sakes someone tell me what the hell is wrong with it ?
Just snagged one for £79 on amazon for camping, considering also getting a 40-60 watt solar panel and having it as my little off grid system
I have the anker 747 haven’t used it for couple months went back to it and it not working
is there way to count charging cycles in other power bank brands.ex: Mi
I believe this is a lithium polymer battery….completely different than lithium ion.
what would be a good industry standard of delivering Watts to laptops at 65?
I personally have almost had this for a year and at 245 cycles and overall health is 90% and works like the day I got it love this device if you can get it on sale use it daily for my phone iPad and Lenovo Legion go
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.
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.
How is it now one year later?
For the animations alone… worth it
When power discharges to 45% it stops charging anymore. I have reached 70 cycles.
Anker support is sh*t
It’s actually shit it keeps losing power without even being connected 😢
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
I have 106 Cylces now.
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?
You don’t get the charger with it. No power Breck and it doesn’t seem to sell what you need to charge it. A complete mestery and almost like a secret what you need to charge it and were to purchase it.
Jackery explorer 100 plus, 2k cicles 120 euros, 128w delivery, lifepo4, the best solution for the money miles away from the rest.
Life cycle maybe short because it’s from Anker (made by Chinese company) I am sure you can find a higher quality portable charger at the same price if you’re careful enough you can find one Made in Taiwan
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 picked one up in the Oct Amazon Prime Days for $109 CAD, great price!
Mine is at 5% after 40 cycles
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.
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
any update on how many cycles now and how is the power bank? thanks
I have an 8 yo jackery 6000 mha power bank with an orange aluminum shell , 4 blue led’s for power level and a single led flashlight, it has lead tough life and is still the go to when my ICRAP 13 needs a quick charge
I am on my 4th now.
* First one the USB-A died after 100cycles
* Second one did not take charge anymore after 100cycles
* Third one did the second USB-C port start die after 200cycles.
300 cycles? All you have to do is never let it run empty and charge it up to 85% and you’ll be fine.
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.
300 cycles ain’t very good…. Lithium cells can last much longer
Then there are brands like Baseus that are claiming 20,000 cycles on their latest power bank the blade 2 which they claim To have EV grade LiC cells

I guess the more important question one should ask is : how many times am I going to charge my mobile phone or any other device with one cycle of this power bank? That’s the magic number to remember.
Anyone could tell me how many full charges you get out of this for iPhone 15 Pro or Samsung Galaxy S24?
I would guess your phone’s battery gets below 80% of its original capacity and has to be changed at least twice before this power bank dies.
These don’t come with a charger yet people never say a word. Beyond odd.
This is why i have a few power banks to rotate i use them for convenience and emergencies had mine for 2 weeks and only have 2 cycles and I went out of my way to get those two cycles just to test this bank if I use this how I plan on using it It will take me maybe a week and a half to drain this battery to where I have to charge it one charge lasts forever when your using here and there instead of stressing it and draining it completely every time you use it if you’re one of those people who really use it like every single day and it’s your main charging source I would recommend getting the bigger generator style power banks ALWAYS remember You DO NOT have to change to phone to full capacity every time you use the power bank its a waste of a cycle
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…
Mine died today after one year lol
80 cycle and i have 92% health
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.
The issue is, ppl don’t know what a full cycle is or how to slow down the cycle count.
One thing I noticed with this power bank it doesn’t stop charging your device even when device is fully charged. I charged my s9 tab ultra with this power bank and noticed it says 37% power left. S9 tab ultra took 50% of power to charge and yet s9 tab ultra has battery 11200mah so where did the rest go?
I noticed power bank was charging my Hauwei p50 phone even when it’s fully charged. Meaning I was losing power in bank.
Strange power bank indeed!
737 secure for asus laptops?
Charging with type c
Anker does not have their old quality anymore
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 barely lasted a 100 cycle then the battery life suddenly went down from 100 to 5 percent
lmao just call customer support
is there no proper non chinese brand that does QA, that makes a power bank for laptops? the market is full of these crap products that are either hit or miss, and longevity wise i bet they don’t last, as chinese things almost never do. So is there anything? Samsung makes one up to 20k but it’s low wattage.
