I am not sure it is ONLY on me or not :
Even play with cave story, the charging speed cannot catch up with the power consumption.
thus the device runs OUT of Power eventually. 
How many amps does your charger have?
Charging with gameshell powered OFF, 0.86A
Charging with gameshell powered ON, 0.28A
Weird, it draws more when powered off, it should be the opposite
Not necessarily, probably mean that the charger is not properly configured when on…
Once I have a battery I will check on my side
Use the 5V plug that came with my Pi.
No issues here
While using power bank for charging in gaming marathon,
(I am using a power bank made by QuanHan, type: PD1002, supports 5V 2.4A , 2.0A charging )
I think most of us will encounter this kind of problem if my case is not a minority report .
I tested out gaming for about 3 hours last night.
Plugged in a completely dead unit, and started to play.
The unit fully charged during use.

It’s the 5v one that came with my RPi
I have confirmed that this is a defect in the mainboard of game shell by switch to a new mainboard without this problem now.
