mAh stands for milliamp hours, which tells you how much charge a battery can hold, essentially reflecting how long it might last before it needs recharging. It is a small measurement unit, with a mAh equaling one-thousandth of an Ah (ampere-hour), generally used in portable electronic devices like smartphones, laptops, power banks, etc.
Think of a battery as an example. If that battery can maintain a current output of one milliamp for 1 hour, you could call it a 1 mAh battery. A milliamp is a tiny amount of power, so this battery wouldn't be very practical. Practically, we see mAh used in any electronic device with a battery, from phones to Bluetooth speakers.
mAh (milliampere-hour) indicates the charge capacity of a battery and how long it can power a device. The higher the mAh rating, the longer the battery is expected to last. How Does mAh Affect Battery Life? Now that we understand what mAh is, let’s take a closer look at how it affects battery life.
The higher the mAh, the larger the battery capacity and the longer the device can run. For example, a smartphone battery with 3,000 mAh means it can provide 3,000 milliamps of power for one hour. Similarly, a power bank with 10,000 mAh can recharge a 3,000 mAh phone battery approximately three times (allowing for some energy loss).
mAh is a measure of a battery’s capacity, not its voltage. However, the voltage of a battery does affect the charger’s output. For example, if you have a 5V charger and a 3.7V battery with a capacity of 2,000mAh, the charger will output 5V, but the battery will only receive 3.7V.
For example, a smartphone battery with 3,000 mAh means it can provide 3,000 milliamps of power for one hour. Similarly, a power bank with 10,000 mAh can recharge a 3,000 mAh phone battery approximately three times (allowing for some energy loss). A 20,000 mAh power bank, on the other hand, can provide around 6–7 full charges for the same phone.
Yes, you can use a battery with a higher mAh rating in your device, provided it is compatible with the device’s specifications. Using a battery with a higher mAh rating can potentially extend the device’s battery life, allowing it to run for longer periods before needing to be recharged.

Reason 1: Power banks output at 3.7 volts, while due to USB technical standards, smartphone batteries charge at 5 volts. This creates an imbalance between the output of the power bank and the ...
Milliampere-hour (mAh) is a unit of measurement that quantifies the energy capacity of a battery. It represents the amount of current (in milliamperes) that a battery can deliver over one hour. For example, a battery rated at 2000 mAh can theoretically provide 2000 milliamperes for one hour, or 1000 milliamperes for two hours.
Let''s see how many charges you might get from a 2500 mAh power bank with various smartphones: iPhone 13 mini: 2400 mAh battery. The power bank could charge it close to 100%. Samsung Galaxy S22: 3700 mAh battery. A 2500 mAh power bank might give it around two-thirds charge. Motorola Moto G Play (2021): 5000 mAh battery capacity.
Charging Power (in watts): Calculate . Introduction. In the era of portable devices and electric vehicles, understanding how long it takes to charge a battery is crucial. Whether you''re charging your smartphone, laptop, or electric car, the time it takes to reach a full charge can vary based on the battery capacity and charging speed. To simplify this process, a Battery Charge Time ...
mAh is a unit of measurement used to describe a battery''s capacity to store energy. The higher the mAh rating of a battery, the more energy it can store, and the longer it can power a device before it needs to be recharged. When choosing a charger for your device, it''s important to consider its voltage and amperage requirements. A higher ...
The SI unit to express stored electric charge is a coulomb (charge delivered by 1 amp for 1 second), but mAh (charge delivered by 1 milliamp for one hour) is the common unit for batteries. In fact, 1 mAh = 3.6 coulombs!
