What batteries are used for box mods?
The batteries used for most mechanical and box mods are either 18650 or 26650. A batteries ability to discharge stored energy is measured in Amps. If you push the battery to its limits the chemicals inside will get hot and start to vent, hot chemicals exiting under high pressure is how a battery blows up!
What is the building block of vape coils?
The building block of most vape coils is Kanthal wire and organic cotton, and you can fund a year’s supply for the same as a pack of coils. Understanding how to measure the resistance (ohms) of the coil on your atomizer is the first step to safety.
How much efficiency does a mod chip have?
Just input how many batteries your device takes, how many watts it is being used at, and the mod's chipset efficiency. A default mod chip efficiency of 90% has been chosen if you do not know your efficiency, this is generally regarded as a conservative estimate.
How many digits are in percentage?
Percentage should be entered as 2 digits (for example, 90 for 90% efficiency).
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 many ohms does sub-ohming vape have?
Sub-ohming takes this further by vaping at a resistance of less than 1 ohm.
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 variable wattage?
A variable wattage device is different. Rather than telling the device how much power you want to flow through your atomiser, you tell it how much power (wattage) you want it to output.
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.
How to get the perfect vape experience?
