What You Should Know

Skim this first for the short version: the main points, the questions people ask, and what to consider before you buy.

Overview

mAh, or milliampere hour, is the number that tells you how much charge your vaporizer battery can hold, and it plays a direct role in how long your device lasts between charges. Understanding it helps you compare batteries honestly instead of guessing based on size or price alone.

Here is what mAh actually measures, how it affects your sessions, and how to estimate how many puffs you will get out of a full charge.

Key Takeaways

mAh measures how much electrical charge a battery can store and deliver over time.
A higher mAh rating generally means longer battery life between charges.
Battery life also depends on your cartridge or atomizer resistance, not mAh alone.
You can estimate puffs per charge by dividing total session time by your average draw length.

How-To

Complete How-To

From here, the walkthrough gets specific: the product details and buying considerations that turn the summary above into an actual decision.

What is mAh and Why it Matters

So, What is mAh?

Sutra Auto full color

mAh describes the milliampere-hour and defines the total charge capacity of your device’s battery. As a unit for measuring electrical power over a length of time, mAh is used for explaining how much energy a battery can store at one time. For example, say a battery is rated at 1000 mAh, it can last about an hour delivering one amp of power (1,000 milliamperes= 1 amp) before it is completely drained.

This means when the battery is fully charged with a higher mAh rating, it can power the device for longer or stronger before it dies and needs to be re-charged.

How mAh Affects Your Device

Now that we have a better understanding of mAh let’s get into how it affects your device.

So, understanding mAh is necessary for calculating how much battery life you will get. First, you will have to know how much electrical current your battery and cartomizer use when engaged.

For beginners, this process can be a bit tricky. Start by dividing the voltage of your battery by the resistance level of your atomizer/cartomizer.

For example, a 2.5 ohm atomizer paired with a 3.7 volt battery would draw about 1.48 amps (or 1480 mAh). If your battery or atomizer has a different voltage or resistance, try using the Ohm’s Law Calculator to determine the electrical current drawn by your device (in amps). Once you get that, then multiply it by 1000 to arrive at your milliampere number.

Estimating Number of Puffs per Battery

The final step in utilizing your new knowledge of mAh is to estimate how many puffs or draws you get before recharging. To determine this, simply divide the total number of seconds you divide the total number of seconds you got to by the number of seconds your average draw lasts.

For instance, your average draw us about 3 seconds long, using the example above you could get approximately 265 puffs out of your battery.

Calculating the lifespan of your battery isn’t an exact science since resistance levels can vary by as much as 0.2 ohms up or down once when in use, but this will at least give you a close idea of how long your battery will last.

We hope this was both helpful as well as educational for our vape enthusiasts out there and hope to see you at our next blog!

Happy Vaping!

Frequently Asked Questions

How-To FAQs

Quick answers to what shoppers usually ask before putting this guidance to use.

What does mAh stand for?

mAh stands for milliampere hour, a unit that measures how much electrical charge a battery can store and deliver over time.

Does a higher mAh mean a longer lasting battery?

Generally yes. A higher mAh rating means the battery can power your device for longer before it needs a recharge.

Does mAh affect vapor production?

Not directly. mAh affects how long your battery lasts, while voltage and resistance affect the strength of each hit.

How do I estimate how many puffs I will get from a charge?

Divide the total number of seconds your battery can run by the length of your average draw to get an estimate of puffs per charge.

Why do resistance levels affect my battery estimate?

Resistance can vary slightly during use, so puff estimates are a close guide rather than an exact number.
