For instance, a vape battery that carries a 1000 mAh rating can provide 1000 milliamperes ...
What is the difference between Mah and Volt and amps?
mAh is the capacity rating of the cell. Volt is the difference of electrical potential between two points (i.e. the + and - ends of the battery) and is commonly expressed as the 'Nominal' voltage of the cell (3.7v for Lithium chemistry cells), and amps is the amount of current.
How many amps does a vape battery produce?
For instance, a vape battery that carries a 1000 mAh rating can provide 1000 milliamperes (which is one amp) for an hour until its energy is drained. A 3000 mAh-rated battery provides an hour of electricity delivered at three amps.
What does the “mAh” rating on e-cigarettes mean?
The “mAh” rating on e-cigarettes can be very puzzling for Vapers who are unfamiliar with electrical terms of measurement. In reference to vaporizer batteries, most people assume that a higher “mAh” rating indicates a more powerful battery.
Which is better mAh or amp?
Higher mAh ratings do not necessarily reflect on speed but more on runtime. For example a 2000 mAh pack will sustain a 2000 milli amp (2 amp) draw for one hour before dropping to a voltage level that is considered discharged.
What is a good mAh for a vape?
The GT Torrch dab rig has an mAh rating of 1500-200, making it the best vape pen for dabbing on the market.
Does mAh matter in vape?
The higher the mAh, the more energy a battery can store and therefore the longer it will last. So as much mAh as possible is great, right, so then you never have to worry about the unit dying in the middle of vaping. But the amount of mAh is completely correlated to the size of a battery.
How many amps should my vape battery be?
The amp limit (or the “maximum continuous current” rating) of a battery tells you how much current it can provide: anything 20 A or over is suitable for most vapers. The capacity (measured in mAh) tells you how long a battery can last between charges: bigger numbers are better!
How long does a 3000mAh vape battery last?
Even a small 300mAh battery should last you for a full day's worth of use, depending on how often you vape. As an example of how mAh works, a 3,000mAh battery gives you 3,000 milliamps for an hour or 1,000 milliamps for three hours.
What does 650mAh mean?
650mAh v 900 mAh - what's the difference? The mAh stands for milli Ampere hour or milli Amp hour. It&' the measure of a battery's energy storage capacity. Imagine your battery as a fuel tank in a car, the mAh is the measure of how much fuel the battery can hold.
Is high or low mAh better?
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. A higher number means that the battery can store more energy, so it has a higher capacity. Of course, this also means longer battery life for a given usage.

A higher quality vape battery is going to give you more charges, consistent power ratings and hold a charge for longer.
What Is mAh?
The term “mAh” is a measurement in milliampere-hours of a battery’s electrical charging capacity. More simply, it’s a unit of measurement that indicates just how much electrical power an item like an e-cigarette battery will provide over a one-hour period.
Calculating Battery Life With mAh
To determine the life span of an e-cigarette’s battery, you’ll need to use an Ohm’s Law or battery life calculator, which can be easily found for free online.
Coil Resistance and Its Relationship to mAh
One very important element that affects just how long a battery can operate in-between charging is whether you’ve got a low or standard resistance coil (commonly called an “atomizer”) that your battery is powering. Resistance in this case indicates the electrical resistance occurring inside the battery’s cells as it produces electricity.
What does mAh mean in battery?
mAh is short for "milliampere-hour" and coveys the total charge capacity of a battery. As a unit for measuring electrical power over a length of time, mAh is commonly used in describing how much energy a battery can store at one time. For instance, a battery rated at 1000 mAh can last for one hour delivering one amp of power ...
How to calculate battery life of a digital cigarette?
To calculate how long your digital cigarette will last with a particular battery, all you have to do is take a look at the Battery Life Calculator and enter the mAh rating of the e-cigarette battery in the first box ("Capacity Rating of Battery"). Then, in the "Consumption of Device" box, enter the value you came up with during the previous step and press calculate. You will probably end up with a decimal number. Simply multiply that value by 3600 (the number of seconds in an hour) to find out how many seconds your battery will last. (Example: .221 hour equals 795 seconds after making the calculations)
How many volts does a vape battery have?
They provide nominally 3.7 volts of power, 4.2 volts when fully charged and slowly discharge when used. Once the vape battery is discharged below approx 3 volts, they must be charged again.
How many charges does a vape battery need?
Approximate number of recharges a vape battery can undergo before it’ll no longer hold a charge. Duty cycles can be as high as 500 charges but will vary depending on the specific battery type.
What is the anode of a vape battery?
Most external vape batteries are Lithium Iron (li-ion) and consist of three parts: the cathode (+), the anode (-), and the electrolyte (bit in the middle). The anode of all 18650 li-ion batteries is basically the same; carbon/silicon and graphite.
What is the circuit board on a vape battery?
Batteries have a small circuit board, usually on the bottom of the vape battery, that stops the charging or discharge of the battery in certain circumstances, such as Over-Charge, Over-Discharge and Short-Circuit. These tend to be slightly longer because of the circuitry and are normally classed as ICR.
What is the difference between a mechanical and regulated mod?
A mechanical mod takes power DIRECTLY from the vape battery, which means it’s important to know that the battery is capable of providing the current required to fire the coil.
How long does a 3000mAh battery last?
A 3000mAh battery can run 3 Amps for 1 hour before full discharge.
Do vape batteries have higher discharge rating?
This makes them more suitable for lower wattage devices. On the flip-side, a vape battery with lower Milliamp Hours will tend to have a higher discharge rating (higher Amperage). And you guessed it, this makes them more suitable for higher wattage devices. There is always a compromise between the two.
What is a vape device?
Vape devices use simple circuits that contain a battery, a switch and a heating coil. The circuit is effectively a controlled short, with the power output from the battery used to create heat.
What does wattage mean in vaping?
To put it another way, watts is essentially how much power your vape produces and voltage is how much power is put through the device. So, as you increase the wattage the voltage also increases and vice versa.
How to get the perfect vape experience?
After all, with most entry-level vape kits, all you need to do is: Check what wattage you can use with the coil in your device. Adjust your wattage and airflow until you get the vapour, flavour and throat hit you need. Some people want to know more to get the perfect vaping experience.
Why do vapes burn out faster?
You will need to increase the voltage to increase the wattage and get a better vape. Because lower resistance coils use more wattage, they tend to generate more heat. This means they often burn out quicker than a higher resistance coil would.
What is the resistance of a sub ohm coil?
The term sub-ohm, while still used, is not as relevant as it used to be. Coils below 1 ohm are common, and coils with a resistance of 0.8 ohms are often used for Mouth-to-Lung vaping. Even lower resistance coils, such as 0.15 coils, are often used for cloud vaping.
How does variable wattage work?
The variable wattage device will then automatically adjust the power going through the atomiser (the voltage) to produce the power output you need (the wattage).
What is the difference between variable voltage and variable wattage?
The difference between variable voltage and variable wattage is a bit like the difference between an automatic and a manual car. With a variable voltage device, you manually control the amount of power (voltage) going through your device.

What is an amp used for?
Amps, or amperes, are used to measure the amount of current flowing through your device. As it relates to vaporizers, you want to know how many amps are being pulled from your batteries.
How many amps does a 12V ohm coil need?
To get the amperage, divide 12V/0.8 ohms = 15 Amps. In this case, you will need a battery of 15 Amps or higher to match the maximum draw from the coil. It is always recommended to get a higher capacity battery (at least by 2A) so you have enough headroom on the amperage.
How do mechanical mods work?
There are 2 main types of mods that are used in vaping. Mechanical mods work in a truly manual design, where there is no resistance between the coil and the battery. This means that the draw of electric current (amperes) that is exerted by the coil is directly transferred to the battery.
How much voltage does a 150W battery need?
For instance, a 150W device with two batteries means you have a 75W load on each battery. To determine your voltage you will need to figure out what the minimum voltage rating of your device is. Most of today’s devices have a minimum voltage of 3.2V per battery before they cut off.
Why does my e-juice vaporize?
The coil then heats up your favorite e-juice and causes it to vaporize. There needs to be a delicate balance between how much current the coil is pulling from the battery. If the coil pulls too much current, it can eventually become damaged.
What is Ohm's law?
Ohm’s law is a physical formula that is used to calculate various dimensions of an electric circuit. You can think of a vaporizer as an electric circuit in itself. During sub-ohm vaping, the total resistance in the circuit is normally less than 1 ohm.
What is the equation for Ohm's law?
Alternatively, there is an extension of Ohm’s Law that includes power as measured by wattage. This equation looks like this: P = I x E . It’s easy to remember, because everybody loves “PIE.”
