Question about Xiaomi MI TV Stick 4K

The stick should be used with the power adapter supplied, as stated in the instructions!
Connecting the stick to the TV via USB can lead to malfunctions, especially if the TV is completely de-energised via a power strip, as I usually do.
The USB socket simply supplies too little power for smooth operation, unlike the adapter.

Works perfectly with power via USB connection on the TV, even if the TV is completely disconnected from the power supply, tested in the camper.

This is also the case: the TV stick has a micro-USB connection for the power supply.
