EB3A switch off randomly after a minute

Hello, I have had this problem with my device for some time.

It is charged to 75% and when I connect some device to charge AC or DC, regardless, after about a minute it turns off completely, goes out and cannot be turned back on.

It only turns on when I connect it to the charger in the car/solar/or a socket at home.

When it is charged, e.g. from the car, at that moment I can have e.g. a laptop connected and charge from the eb3a battery, however, as soon as I disconnect the charger from the eb3a from the car, it turns off again and cannot be turned on until the next time it is connected to charge, e.g. from the car.

I tried pressing 3 buttons, I have the latest update on the bluettii app

ARM v2063.03
DSP v2052.11

Thanks in advance

Are there any error codes displayed in the app or on the screen?
No error
What load was connected when the issue occurred, and what was the specific power?
Just smartphone charger
Did removing all loads and restarting resolve the problem? No
When connected to a grid power source, does the screen light up? Yes

@BLUETTI_CARE can you help? Thanks
