Power Bank: How do you check the battery health of a power bank?

Thu, 26 Mar 2026 23:25:26 -0700

Is there a way to test the battery capacity? I have a couple Anker power banks, PowerCore 500 and 337/PowerCore 26K. Both are about 7 years old and been used very intermittently. I'm assuming the capacity has diminished with age, but want to get a better idea of how much since hoping to use them on an upcoming trip. The light indicator on both shows full though I can't recall the last time I charged them.

I'd also like to troubleshoot an Anker A1501 Jump Starter Portable Charger, which is about 8 years old. Noticed it seemingly stopped working 2-3 years ago. When plugged in it'll show as charging, but doesn't do anything if try to use the built-in flashlight or charging ports. Never used the feature to jump start a car.

Power Bank: 500 watt Aukey Portable Power Station won't charge via any input

Wed, 04 Mar 2026 00:46:50 -0700

I have a Aukey PowerZeus 500 power station — a 500 watt lithium-ion electric "generator" device. When I got it, I couldn't get it to charge. It turned on, and I could power devices off the small amount of electricity that it shipped with in the cells, but no matter what way i tried to power it, it wouldn't register an input and eventually drained to zero.

Aukey sent me a replacement charger, but it didn't change anything. So they sent me a new unit, but declined having me send this one back (I assume they didn't want to deal with shipping lithium batteries a second time). The new one worked fine.

So now I have two units, a good one and a bad one. And the bad one has been sitting in the closet for a while now. It's as big as a toaster oven.

I've wondered if this is something that might be worth looking at internally. Could it be a simple fix? My instinct says no, hence it still sitting intact. But I am not sure what else I might do with this. Send it to e-waste? Any thoughts?

Power Bank: battery poked accidentally, is it safe to use?

Wed, 28 May 2025 06:17:30 -0700

Beetle flix 20K power bank was working fine, except its switch on the side sunk inside, so i tried prying it open and accidentally poked the battery by a screwdriver, that spot is giving sparks even when touched with hand or screwdriver, gives out burning smoke. Power bank is working fine. Can i just apply tape and continue to use it? In fact sparks came out even while applying tape and burnt it a bit.

actually, the prompt forced me to use a "strong title." Sorry. Just really want to know if charging it from a 1mA charger will harm the device. I've searched and searched and best I can find it "input; up to 2mA." Thank you in advance!

Power Bank: How to open RoHS PC3 power bank

I found a RoHS power bank, the i/o board is dislodged - what tools are required to open the housing - secure the board back into place - seal it ready for use?

I am speculating I require a heat gun, and super glue.

Power Bank: Why is my battery pack self-discharging?

Sat, 09 Nov 2024 06:14:54 -0700

I have a 4Patriots D320 powerbank that was sitting unused and not charged for a couple of years. It would not charge, so I removed the battery pack that consists of 4 series connected groups of 6x 26650 cells in parallel with a charge/discharge PCB. One of the groups was totally dead. The other groups were all about 3.2V. I removed the dead group. The rest are still connected to the charge/discharge PCB.

I charged each group individually with a simple smart Li charger at its max of 1A. They all charged up to ~4.15V. After a day, the voltage on all the groups was down to ~3.5V. I recharged and after 8 hrs they are ~3.8V.

Is this what I should expect, or is something else happening?
