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*h@5Volts, which gives 5900mA*h@3.6V. Provided this was charging from 25% to 100%, full charge should take 28.3W*h or 7900mA*h@3.6Volts, which is close to seller's claim.
