DIY 4x18650 Battery Charger, Battery Charger Case,Portable DIY Power Bank Box, 2 USB Output, Type-C Input and Output, Support PD/QC/SCP/FCP/AFC/PPS/PE, Not Include Battery (Black)

Good use for spare 18650s I had laying around. Would rather use it for a nice pwerbank than through them away and this does the trick pretty nicely

The item is made out of extremely flimsy plastic and probably weighs less than an oz. The 'LED screen' they advertise only turns on when you push 1 of the 2 unlabled buttons on the sides of the LED display, at which point it lights up, poorly, you can clearly see 1 point of the display has most of the light on it while the rest is dimmer, and all it says is 25 50 75 100 on it. No button presses, no plugging the thing in changes anything on the display, the second button on the thing does nothing at all.Probably a dropshipped item off alibaba for 5 cents each.

It works well but you have to have the right kind of batteries. I feel like some people do not read the full description and thought it was for standard AA batteries . It's lightweight and efficient for charging. It comes apart easily.

Easy to use

This amazing piece is a gift for your electronic stuffs. Imagine how many batteries you need for them, this piece is the solution.

Cool power bank for people with loose 18650 cells. I scavenge Ebike battery packs for 18650’s to test/sort. The good ones keep on delivering mobile USB power.The buttons don’t make much sense to me. Sometimes they turn ON the very basic 25 50 75 100 capacity meter.USB C port is bidirectional. I discovered the unit will work with 1, 2, 3 or 4 cells.Depending on the cells used it’s probably good for about 35-50Wh. And the good news is that when those cells start to fail they can be replaced.

Used this product 1 time. When charger hit 25% I pulled the batteries to recharge. Charger reads all batteries as fully charged, but doesn’t work in any devices I have.Hate to leave bad reviews but that’s over $60 I lost in all for 1 use.

I've purchased a few of these. Add your own 18650 battery chargers and this one is the absolute best hands down.Holds charge even. Compact. Buttons don't depress accidentally. Case stays shut.
