"It is perfect!
Charger weight is 138g.
It adds 10mm thickness to the phone.
Camera views are not obstructed by the battery case.
To estimate battery capacity, I have first discharged powerbank to red LED (25% full), and then measured W*h to charge it to full. The result was 21.23 W*[email protected]
, which gives 5900mA*[email protected]
Provided this was charging from 25% to 100%, full charge should take 28.3W*h or 7900mA*[email protected]
, which is close to seller's claim."
