Power-bank calculation

How many full charges?

We take 75% of the power bank’s rated Wh and divide it by this phone’s 11.97Wh. This is a planning estimate, not a charging guarantee.

5,000mAh class≈ 1.2×

18.5Wh rated → 13.9Wh planned delivery

10,000mAh class≈ 2.3×

37Wh rated → 27.8Wh planned delivery

20,000mAh class≈ 4.6×

74Wh rated → 55.5Wh planned delivery

(power-bank Wh × 0.75) ÷ 11.97Wh
