T-Beam turns off, even when powered by USB

I have tried to use meshtastic on a T-BEAM I still had.

Turns out everything works just fine, but after some time the device just powers off.
The only way to wake it up again then is to remove the USB power and plug it in again, or pong press the power button.

Is it a known issue?

Same issue. Did you find a fix for this yet?

If you’re using a power bank it could be turning itself off once the current drops below a certain level. Some power banks have a low current mode to ensure the power remains on.
