Pixel 8 Pro
A large Pixel battery whose real charge count is lower than a generic 15Wh-phone estimate suggests.The Pixel 8 Pro battery stores 19.25 watt-hours.
The genuine replacement battery lists 4,950mAh at 3.89V. Google separately lists 5,050mAh as the typical capacity; rated and typical capacity should not be silently mixed.

How many full Pixel 8 Pro charges?
We multiply the power bank’s rated Wh by 0.75, then divide by the phone’s 19.25Wh battery. The result is a planning estimate, not a laboratory 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) ÷ 19.25WhThree useful sizes for the Google Pixel 8 Pro.
These are capacity classes, not paid rankings. The charge count uses this phone’s 19.25Wh battery and the same 75% delivered-energy allowance.

19.25Wh tells you how much.
Charging watts tell you how fast.
The phone, charger and cable must negotiate the same charging profile.
Alignment, heat and charger certification can reduce real wireless power.
Two sources, two different jobs.
The manufacturer page supports the phone and charging claims. The model-specific iFixit source supplies the battery figures used here; where voltage is not printed, it is explicitly labelled as derived. Replacement parts are labelled as genuine or aftermarket according to that source.
Keep energy and charging power separate.
How many Wh is the Google Pixel 8 Pro battery?
The genuine replacement battery lists 19.25Wh, 4,950mAh and 3.89V. Watt-hours are the most useful capacity figure when comparing it with a power bank.
What is the Pixel 8 Pro battery capacity in mAh?
The battery evidence lists 4,950mAh. Google separately lists 5,050mAh as typical capacity. Rated and typical figures describe different points, so this page labels them separately.
How many times can a 10,000mAh power bank charge the Pixel 8 Pro?
A 37Wh power bank gives about 1.4 full charges in our planning calculation. That assumes 75% of the power bank's rated energy reaches the phone battery; actual results vary.
What size power bank is useful for the Pixel 8 Pro?
A 10,000mAh-class power bank rated around 36–37Wh is a practical everyday class and gives about 1.4 full charges in this calculation. A smaller 18.5Wh pack gives only about 0.7 charge, while a 74Wh pack gives about 2.9.
Does 19.25Wh mean the Pixel 8 Pro charges at 19.25W?
No. 19.25Wh is stored energy. Charging power is a rate measured in watts; for this model the sourced charging description is Fast USB-C charging with a compatible PPS charger.
