How many full charges?
We take 75% of the power bank’s rated Wh and divide it by this phone’s 17.77Wh. 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) ÷ 17.77Wh17.77Wh 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 Irish 230V 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 Irish retail availability or an included charger.
Keep energy and charging power separate.
