need a usb tester. which one should i choose?

Yes

A working one

🤔

i think i broke my usb tester when i plugged it into a fancy samsung fast charger

its something like 9V 2A

TFW 12v

or 12

there are a lot of brands, thought someone could tell me a reliable one

oh fast charging can ruin the tester?

my huawei charger has that shit

there are probably fancy testers that don't break with that

Had this one, pretty shit

same

I can't find the other one I got

With mAh measurement

that last tester i linked looks neat

doesnt look like its available anywhere though

looks nice indeed

you mean the coloured ones right?

ye

🤔

they are expensive as shit

geezuz

yeah i think they're out of production

YZXstudio also makes a neat diy powerbank, but i think you can only get it via taobao

i have a xiaomi one

works pretty good

but it looks like they discontinued that too

rip YZXstudio
