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.

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!

Thank you! This is both reassuring and informative!

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.

Really well made and informed video - kudos and cheers!

Thank you for the video. It’s excellent and I’m happy that I learned that today.

Very interesting. Thanks. I have two of these. Love them.

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.

Very informative. Thanks mate! 👍

That’s good knowledge and it should be shared. Ty 😊

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 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. :)

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 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.

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.

Very useful to know. Thank you.

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 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).

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

Great video brother thanks

You are really a good product reviewer

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

Mine is at 84 cycles right now and still rock solid at 100% battery health

thank you for this video :)

My 2017 20100mah anker is still working well!

excellent video

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.

i like this guy presenting style, it felt like top gear

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...

I use the belkin 20,000mAh portable charger compatible with 20w input and output. If I had a 5w charger to charge it with, it could probably last about 6 years given that it goes through 1 charge cycle a week

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%.

I trust anker porducts.. i order anker 737 its look nice and good for outdoor use

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

Thanks a lot

Mine just hit 50 cycles today still going strong.

Excellent commentary

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 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.

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.

Of Anker chargers, so far only model 717 has PD 3.1 delivering over 100watts.

OK, that quite a good explanation.

Damn now I want one

i have a power bank with 10000mah from like 7 years ago still runs good. really thinking of getting this one.

What happens is one cell goes bad and unit will shut down. When the voltage drops they don't allow charging I've found.

how many cycles have you used to date?

I got the 250 watt it’s a wonderful addition to the power bank collection

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

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.

Thought for sure those cells 21700 series.

300 cycles? All you have to do is never let it run empty and charge it up to 85% and you'll be fine.

I'm getting a UVP warning and ot shutdown off. Can only use it as a passthrough if it is plugged in.

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.

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.

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.

Could you post an update on this please? (if you haven't already, and i just can't find it!)

what would be a good industry standard of delivering Watts to laptops at 65?

I have the anker 747 haven’t used it for couple months went back to it and it not working

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 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

Mine stopped charging after 8 cycles

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.

is there way to count charging cycles in other power bank brands.ex: Mi

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.

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!

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.

Remind me to ask "Does it still work?" in 2 years (because of mandatory 2-year warranty in Europe) 😄

Its not hard limited. Every powerbank will slow over time. The data on display is awesome to see.

Will be back in a few years for the "replace batteries and reset charging cycles" video

That’s good enough for me

Make a review on shargeek storm 2 cycles

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%.

If it's easy to remove the case, I'll replace the batteries, which I always do

21700 batteries are used there

The information about how many times the display was turned on give me more anxiety that the cycle of the cells. :P

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.

I do have a question I don't know if you have the answer I couldn't find it anywhere if I charge the battery to 80% and just leave it how long should it be before I need to recharge it again

Hi there, can it be taken in hand baggage in an international flight as per rules?

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

This is intresting. My powerbank shows 95% battery health after 27 cycles. I use Anker Nano II 65W for charging. What could be wrong?

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

This or Shargeek storm 2 slim for steam deck and oculus

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?

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.

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

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).

A question How the charging cycles calculated

Bro didn't came with facts, bro came with a story

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?

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.

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...

More worrying with this heavy monster is that it probably won't survive a single drop...😂

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.

Is this power bank allowed on any airlines traveling abroad?

You also lose power too as the battery gets used, people only talk about the capacity and totally ignore the power which is also a selling point. That 140W is probably going to become more like 80W.

I'll come back to this video when mine reaches 300 cycles and ill let you know

So lets entertain the matter that if one brought brand new and used the battery to 80% where Anker says that consumers shouldn't use due to battery swells or overheating and could potentially blow up or something and one's guarantee has not run out yet, does that mean Anker will give out a new one because still under guarantee??!!

Me watching this video on my 2500+ battery cycle iPhone plugged into my anker + 500 cycles no issues 😶

A 2nd gen version of this with LFP cells and GaNPrime would be epic!
