Milliamp-hours to kilowatt-hours
Type a value in mAh to get it in kWh instantly.
That's 1.23× as big as a phone battery, while a 10,000 mAh power bank is 2× bigger. That is about 1.233 full phone charges.
Convert the other way: kWh to mAh
What it means
How much energy is that?
Airlines limit spare batteries to 100 Wh without approval, which is why the Wh figure matters.
The math
How to convert mAh to kWh
Charge becomes energy only once you know the voltage: Wh = mAh × V ÷ 1000. The figures below use the voltage selected above.
Example: 5,000 mAh = 0.0185 kWh.
The table below assumes Phone cell (3.7 V). Change the voltage above and every number updates.
