Pixel 7a
The smallest battery in this first Pixel reference set, but still larger than the site's old generic 15Wh assumption.The Pixel 7a battery stores 16.55 watt-hours.
Every calculation below uses the model-specific 4,300mAh figure. The separate typical value of 4,385mAh is labelled and not silently mixed with rated capacity.

How many full charges?
We take 75% of the power bank’s rated Wh and divide it by this phone’s 16.55Wh. 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) ÷ 16.55Wh16.55Wh 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 Canada.
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 Canadian retail availability or an included charger.
Keep energy and charging power separate.
How many Wh is the Pixel 7a battery?
The model-specific source lists 16.55Wh and 4,300mAh. Watt-hours are the useful figure when comparing it with a power bank.
How many times can a 10,000mAh power bank charge the Pixel 7a?
A power bank rated around 37Wh provides about 1.7 full charges in this planning calculation. We assume 75% of rated energy reaches the phone battery.
Does 16.55Wh mean the phone charges at 16.55W?
No. Wh is stored energy; W is charging power at a point in time.
