sorted byIn this case, 30,000 mah x 3.7v/1,000= 111Wh which is above the limit on a flight. 26.8k mah is 99Wh. (edited)
In this case 30,000 mah x 3.7v/5v = 22,200mah.
The average efficiency rate for a power bank is 85%. The rubbish ones closer to 70%.
If we assume this is 85%, the Real capacity for this power bank is:
3.7 x 30,000 x 0.85/5 = 18,870 mah
Add a bit more loss related to the cable you use, and a 30k decent power bank gets you about 18k mah real capacity, which is 40% less than the advertised capacity. A rubbish power bank will be 50% or less real capacity. (edited)
