Only used 4% of my 30,000 mAh power bank to charge up my phone up to 71%

Just able to spare time to fully test my 30,000 mAh power bank.

It manage to charge up my Samsung Galaxy A11 phone 71% (from battery level 22% to 93%) within 3 hours and 25 minutes (from 12.15 pm to 2.40 pm). Despite I used my fast charging cable.

Screen shot of the process.

The power bank battery just 4% used (from 34% to 30%).

Still better than nothing.

The only cons of it is it is way heavier. 614.8 gm per power bank only.

Until then, have fun in using a heavy 30,000 mAh power bank.
