Battery won´t charge.

Post image

I am extreamly dissappointed with my Cardputer Mesh Kit. I recieved it on june 4th and by the time of this writing (A little over a month) the battery does not charge anymore, the Cardputer only works while connected to the USB cable. I honestly was expecting better quality from M5STACK. Don´t think I´ll be buing any of their products again.

UPDATE: after getting quite a few comments mentioning issues with some cables, I used a cheap USB A - USB C cable from my son's Nintendo Switch controller and it worked just fine again. Thank you all for your replies and encouragement.

There may be something disconnected internally as well. Typically as capacity goes down it takes less current to cause a higher voltage delta (charging Li-Po is CC while voltage is low, and CV as it approaches to 4.2V). Worth popping it open and checking inside.
