What is a mAh and why does it matter to vapers

mAh is a term that you may have seen on the side of the new device or description on a vape that you are thinking about purchasing. You may have found yourself asking what this means and why is it important? Look no further than this blog, it will explain what that number means and will having a better understanding of it will help you make decisions on almost any product with a rechargeable battery including your smart phone. mAh means milliamp hour and is a unit that measures (electric) power over time. It is commonly used to measure the energy capacity of a battery. In general, the more mAh and the longer the battery capacity or battery life, for example a device that rates at 4000 mAh is more likely to last longer than a device that is rated 2000 mAh. mAh does not affect the battery power output, but it does represent how much energy is stored in the battery. However, it is not that simple, factors such as power settings, the type of coil and frequency of use will have a big impact on the amount of time your battery lasts.

How can I make my battery last longer?

As mentioned mAh is not the only factor determining how long your battery lasts. If you’re used to vaping at high wattage, you can try turning your device down to a lower wattage. This will help to make the battery last for a larger amount of time and could be the difference between it lasting the day while you’re out or not. Similarly, by changing the coil to a higher resistance will also make a difference. If you’re using a sub ohm coil now, try using a coil 1 ohm or above to help the battery last longer. While a higher mAh is a good thing for the battery capacity, it is still relative to the draw of milliamps placed on it. For example, For, instance, a 4000 mAh battery could power a device drawing 100 mA (milliamp) for 40 hours. A device drawing 200 mA would last only 20 hours. The higher the wattage and the lower the resistance of the coil the more mA that are being drawn from the device.

Why can’t science make the amount of mAh much larger?

Unfortunately for larger amounts of mAh to be possible it would require much larger devices in both size and weight. Typically, consumer items that are bigger and bulkier tend to not be popular as they are more cumbersome to carry around. This is particularly true with portable devices such as phones and vapes. An example of this is the VooPoo Argus Air comes with a 900mAh battery and only weighs 68 grams, whereas the Innokin Mini Proton Ajax kit comes with a 3400mAh battery and weighs 188 grams and is a much larger device overall. You can see that the increase in battery storage capacity has a direct affect on the weight.


Hopefully by now you have a better understanding of mAhs and battery capacity. It is something to consider when buying a new device, while more mAhs may equal a larger battery life, there are other factors to consider in extending battery life, as well as weight considerations."
