When shopping for portable power banks, smartphones, or laptops, you may have come across the term “10000mAh” or similar capacity ratings. But have you ever wondered what this number actually means? In this article, we’ll delve into the world of battery capacity, exploring the concept of milliampere-hours (mAh) and its significance in understanding the performance of your devices.
What Is MAh?
Milliampere-hours (mAh) is a unit of measurement that represents the capacity of a battery. It’s a way to express the amount of electric charge that a battery can hold. In simpler terms, mAh measures the battery’s ability to supply power over a certain period. The higher the mAh rating, the more energy the battery can store, and the longer it can power your device.
To break it down further, let’s consider the two components of the mAh unit:
- Milliampere (mA): This measures the flow rate of electric current. A higher milliampere rating indicates a faster flow of electricity.
- Hour (h): This represents the time over which the electric current flows. A higher hour rating means the battery can sustain the flow of electricity for a longer period.
How Is MAh Calculated?
The calculation of mAh involves multiplying the current (in milliamps) by the time (in hours) that the battery can supply that current. The formula looks like this:
mAh = Current (mA) x Time (h)
For example, if a battery can supply 2000 milliamps of current for 5 hours, its capacity would be:
mAh = 2000 mA x 5 h = 10000 mAh
What Does 10000mAh Mean In Practical Terms?
Now that we understand the concept of mAh, let’s explore what a 10000mAh rating means in practical terms. A 10000mAh battery can supply a current of 10000 milliamps for 1 hour, or 5000 milliamps for 2 hours, or 2000 milliamps for 5 hours, and so on.
In real-world scenarios, a 10000mAh battery can:
- Charge a smartphone with a 3000mAh battery 2-3 times
- Power a laptop with a 50Wh battery for 2-3 hours
