How much energy is
inside your phone?
mAh is the familiar label, but watt-hours reveal the energy a power bank must actually replace. Choose the exact sourced model below.
Find your exact phone.
Every model has a regional English reference page for Canada, with source data and a transparent charge estimate. Retailer availability remains a separate check.

- ≈ 1.7 full charges
Galaxy S25 Ultra
Samsung's 2025 Ultra retains the same sourced rated energy as the S24 Ultra, so power-bank charge estimates remain almost unchanged.

“How many watts is my battery?” can mean two things.
Wh is stored energy
Watt-hours help estimate how many full charges another battery can provide.
W is charging speed
Watts describe the charging rate. A 30W adapter does not mean the phone contains a 30Wh battery.
