10pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions

great product and fast delivery.

They are cheap for a reason, they are very good and do what they are intended for but they dont last long, used regularly you will expect each one to last 2-3 weeks, hense coming in packs of 5 or 10.Little side note, you can tranfer components from one to another to fix a failed one, ive also found that mostly the components used are the same regardless of USB port used eg Usb-C or micro-Usb

Being a 'tinkerer' I have thoroughly enjoyed using these. Simple to set up & use. Would highly recommend.

I used these to modify a Game Boy Colour to have a rechargeable battery. I'm not sure if it was me, but for ages it wasn't providing a connection to the Game Boy. I ended up bridging the battery connection and the output solder pads and it all seemed to work fine afterwards. It may be my poor soldering skills thoughAfter that it works and charges the battery no problem.One thing to note, these boards don't work with fast or super fast chargers. A normal 1 amp plug will be just fine, like an older iPhone plug

I have used 7 out of 10 so far and they are all working just fine. They are also really easy to solder on

The ones I have used worked well. The onboard charging indicator lights are really special

Does exactly what it says on the tin...

Will NOT charge from a USB-c charger, but will charge from a USB-A charger via a USB-A to USB-c cable. What this tells me, is that they have omitted both the tiny chip that talks to USB-c chargers to tell them what voltage they need to supply, AND the pull up resistor between one of the data lines and +ve, that is supposed to provide a fallback option, to trigger the charger to supply 5V.
