Milliamp-hours to amp-hours
Type a value in mAh to get it in Ah 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: Ah 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 Ah
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 = 5 Ah.
The table below assumes Phone cell (3.7 V). Change the voltage above and every number updates.
