I would like to return it
It gets so hot you can't even hold it in your hand and it charges up to 50%, then it cools down and stops charging.

Small
Cheap
Can charge and discharge via USB C.
Unfortunately, the capacity is just under 16Wh (equivalent to 4320mAh), charging consumes 23Wh (6216mAh), a relatively low efficiency.
