Runs perfectly, only the plastics creak between each other, but that's a minor detail

Nice power bank for more energy-intensive laptops. I would certainly be happy with just 65W of output and would appreciate more efficiency or capacity. Overall, I am satisfied with it mainly for the price and I give 4 stars because of overheating and low efficiency.
The design looks fine
Capable of delivering up to 140W
Very tempting price under a thousand on sale
The display shows the delivered power
Multiple outputs, pulls everything and laptops
Low power mod charges even watches
It gets quite hot even when running at lower power (around 20W) - as someone wrote here, it will have low efficiency (I will test)
Feels heavy even at the claimed 25000mAh
The body of the power bank is plastic and easily scratched

Tested - very low efficiency 77%. The resulting capacity is only 70Wh. What to expect during the test: Top quality (85% efficiency): approx. 76.5 Wh Good quality (80% efficiency): approx. 72 Wh (common standard of better brands) Average quality (70% efficiency): approx. 63 Wh Minimum: If you measure less than 60 Wh (about 65%), the power bank is either of poor quality or the cells are defective.
Tested - Except for capacity, all parameters are met
Looks nice.
It's working properly
Low efficiency only 77%
Capacity only 70Wh (90Wh in parameters)
