How many full charges?
We take 75% of the power bank’s rated Wh and divide it by this phone’s 16.95Wh. This is a planning estimate, not a charging guarantee.
18.5Wh rated → 13.9Wh planned delivery
37Wh rated → 27.8Wh planned delivery
74Wh rated → 55.5Wh planned delivery
(power-bank Wh × 0.75) ÷ 16.95Wh16.95Wh tells you how much.
Charging power tells you how fast.
The phone, USB power adapter and cable must negotiate a compatible charging profile. Use certified equipment suitable for the UK 230V/50Hz supply.
Alignment, heat and charger certification affect real charging power.
Two sources with different jobs.
The manufacturer supports the phone and charging claims. The model-specific battery source supplies the figures used in the calculation. These technical figures do not prove UK retail availability or an included charger.
Keep energy and charging power separate.
