Pocket one doesn’t recharge

Hey.

RAK Pocket One with Board One.

Anybody knows why it can’t be recharged by power bank?
Pocket starts after connecting.
Charging stops after a half minute. Power bank goes off.
Pocket one: Power on/ off doesn’t matter.

Power bank 10k mAh. Bank is good. Can recharge board 19007.

Thx

Welcome to the forum @Venditor

I have the same problem with some power banks.
The charging current pulled by the WisBlock boards is quite low (depending on the battery level) and might be ~200mA.

Some power banks shut off when such a small current is consumed.

Power Bank model Works?
Bavin PC182 5Ah yes
TDK X-103DX 10 Ah yes
ROMOSS sense 6 20 Ah no
no brand P88 10 Ah no
