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.

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!

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.

Thank you! This is both reassuring and informative!

Really well made and informed video - kudos and cheers!

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.

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 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.

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. :)

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 have been using 18650 battery's for 6 years now, still working great, all of them have no problems, They have been heavily And i have old anker power banks from 5 years ago, still working well....

[jesselam]

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.

[CaptainMarmite]

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

[stephenmcfarlane]

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

[thatfloridian]

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

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).

[TheStopwatchGod]

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

[autumnrose_tv]

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

[jaredwilmarth]

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
