[@marinamarinx7655]

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.

[@bits2646]

I'd love to see additional testing of cells itself to see how consistent they are in specification, with 18650 I had lots of bad luck with chinese batteries, especially when introduced to temperature fluctuations, mostly outside use in winter it just dropped far below 3V

[@thetechlibrarian]

Not all chinese cells are bad. Anker is a reputable brand. I am pretty sure they are sourcing these 21700 cells from well known makers. The general bad 18650 cells are those ultra fire or similar named stupidly high capacity claimed cells..

[@ericklein5097]

These Lishen cells are pretty good quality, on par with Samsung 40T but expect a lot of 100/140W PD charging to really the life cycle count. Cells that are driven near their max will degrade much faster than standard 800-1200 cycle life. Check the datasheet to see if Lishen goes into detail or just gives one number

[@Buciasda33]

Looks huge, next time add a 0.5 liter Coca Cola bottle for scale. It would have been more useful for this thing to come with a 200W USB C charger. Anyway, I guess you can "charge it" at 140W while having another device draw 140W from it.

[@AnIn-xc4cv]

If I have a light with 45Wh and 12V, how long does it take to consume the power bank? thank you

[@H_ruma]

Can you attach more batteries to it pushing the battery capacity to 80,000mAh ? I am thinking of doing it and 3d print a new shell for it too.

just wondering, is there any batter management as far as balancing leads to help maintain the batteries health?

[@ericklein5097]

Yes, the lower board does all that. The cells must have balancing or they will eventually drift apart and give you less and less capacity as the charger stops working when the lowest cell hits a predetermined low voltage cutoff.

[@muhammadtaimoor9516]

Hi there, I have a favor to ask you for. I watched your video and opened up my defected anker 737 today, I didnt have a grinder so i had to pry it open with a spudger. I succesfully opened it up but in a process i broke its display lcd. I was wondering if you still have that display with you somewhere sitting and if its not in use can i buy it from you ? I'd really appreciate it and it might help me revive my powerbank, since I kind of figured out what's wrong with it, it's b2, b4 and b6 batteries are under voltage, rest of the 3 cells are around 4volts but these 3 are between 3.01-3.17. they discharge to less than 2.5 very quickly and the powerbank shuts down automatically. I was initially thinking it might be the firmware issue but um its not, Maybe just a BMS and these 3 cells are the main issue here which i'll try my best to fix on my own but i broke my display. Please let me know if you read my comment, if i could buy your tore down 737 display. i have very low hopes but um yeah. have a good day sir. :)

[@ChargerLAB]

Hi, I appreciate your message and the effort you've put into trying to fix your Anker 737 power bank. I'm glad to hear that you found my video helpful in your troubleshooting process. However, I must apologize because the display from the Anker 737 that I tore down in my video is no longer available. It was a part of a teardown done quite some time ago, and I don't have any spare components from that teardown. Best of luck with your power bank repair, and have a great day!

6A max cell current? That will be 6A at 18v when the cells are low and under load. 140W output will then be out of spec for the cells...

[@rubberduck8867]

Sounds abotu right, mine had ports cutting out and power delivery going down when 2 devices were plughged in no matter the ports used. It also had issues withthe steam deck and would require a full reboot (by leaving it for 10 mins unused) to try and get the right wattage. but as soon as you plug a 20w phoen in the 38 watt charge went down to 22w... Was an absolutely awful product, I showed the videos of the poor performance and anker's response was this is normal function. I find the 140w number extremely misleading

[@Atmel13]

There is "Continuous Discharge Rating (max): 35A / 45A with 80°C temperature cut" in the LR2170LA specs. It's strange that only 6A was announced in the video.

[@Stainless316L]

My 737 lasted a few weeks got it to about 7 cycle's. Put it on charge the other evening it said charging came back later to find 0% charge. I thought thats strange. Anyway it turns out that the battery thinks it's temp is -40 and it's basically given up saying it's got 5% battery and 0 cycles on the detail screen 5% on the other screen. Won't take a charge and won't give a charge. I'm really not impressed with such an expensive piece of kit doing this so quickly I wanted it to last me years at that price. Seems like they've overcomplicated things with the software and it has glitched displaying incorrect information. The next day the screen was completely dead as if the battery is thoroughly drained itself will not take a charge or anything. 👎

[@Erin-Thor]

@@run00n0 - Cool! So I can plug my iPad Pro directly into a wall socket with no adapter. Thanks!

[@deang5622]

@@run00n0 Nonsense. There is no communication for that purpose. Clearly the basics of electricity are not understood. I shall explain. When a power source specifies a watt figure, this is the maximum power that can be drawn from the power supply. It does NOT mean that the power source will always deliver 140 watts regardless of what you connect to it. For voltage sources, which this is (as opposed to a current source), a set voltage is output. Now, the load, the thing the power source is connected to, will draw current and how much current is drawn is entirely up to the load (within limits which are set by the power source). So the the power drawn is a combination of the voltage and current (P=V.I), therefore as the load or different loads draw different amounts of current, the power drawn from the source also changes. So if you connect a 140W charger to a 40W IPad, then as long as the power supply has the correct voltage for the IPad, then there is no problem, the IPad will draw the amount of current it needs, and the power source -the battery - can deliver it (because the requirement of 40W is less than the maximum power of 140W the power source can deliver). No need for any communication between battery and IPad. Now, USB-C supports multiple voltages, unlike earlier versions of USB which are all fixed at 5 volts, so there is a danger that too high a voltage could be delivered to the load, to the device being charged, and that is then where communication comes in, to ensure that the correct charging voltage is used.
