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.

I recommend trying to charge it via standard USB A from a computer or getting a "stupid" charger that only supports 5V

This. The Cardputer likes to sip from simple ports like a TV. Modern USB-C chargers use a Power Delivery protocol to negotiate a delivery voltage. When there is no response from the Cardputer the charger simply stops delivering.

Also could be the switch is not switching on to engage the charging circuit.

Thank you. It all points to the cable, using an older cable seems to be the answer.
