Pixel 8a

A smaller reference battery that still stores more energy than the 15Wh generic planning assumption.
Direct answer

The Pixel 8a battery stores 17.04 watt-hours.

Every calculation below uses the model-specific 4,404mAh figure. The separate typical value of 4,492mAh is labelled and not silently mixed with rated capacity.

Power-bank calculation

How many full charges?

We take 75% of the power bank’s rated Wh and divide it by this phone’s 17.04Wh. This is a planning estimate, not a charging guarantee.

5,000mAh class≈ 0.8×

18.5Wh rated → 13.9Wh planned delivery

10,000mAh class≈ 1.6×

37Wh rated → 27.8Wh planned delivery

20,000mAh class≈ 3.3×

74Wh rated → 55.5Wh planned delivery

(power-bank Wh × 0.75) ÷ 17.04Wh
Capacity is not speed

17.04Wh tells you how much.
Charging power tells you how fast.

Wired chargingFast USB-C charging; verify the charger profile

The phone, USB power adapter and cable must negotiate a compatible charging profile. Use certified equipment suitable for United States.

Wireless chargingQi wireless charging

Alignment, heat and charger certification affect real charging power.

Frequently asked

Keep energy and charging power separate.

How many Wh is the Pixel 8a battery?

The model-specific source lists 17.04Wh and 4,404mAh. 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 8a?

A power bank rated around 37Wh provides about 1.6 full charges in this planning calculation. We assume 75% of rated energy reaches the phone battery.

Does 17.04Wh mean the phone charges at 17.04W?

No. Wh is stored energy; W is charging power at a point in time.
