Vaping Terminology Tutorial: Re-wrapping a Battery Understanding Battery Capability/Capacity Why does my Tank Leak and what can I do about it? Why does my atomizer crackle&pop and spit hot juice on my tongue? Understanding the relationship between power and coil resistance Why do we...

The process for picking a coil and battery for a mech is pretty straight forward. 1. Choose a (realistic) power level 2. Use ohms law and/or steam-engine to choose a coil/s that provides this wattage 3. Calculate what amp draw this will generate. 4. Pick a battery that of a known and proven CDR...

You can measure the voltage drop (inefficiency) of an unregulated device by putting a resistance/volt meter across the positive and negative posts of a atomizer, loaded with a coil as it needs to be measured under load. Measure the voltage and subtract it from the voltage that was in the...

# 18350 – A battery with dimensions 18mm x 35mm in length 18500 - A battery with dimensions 18mm x 50mm in length 18650 – A battery with dimensions 18mm x 65mm in length 20700 – A battery with dimensions 20mm x 70mm in length 21700 – A battery with dimensions 21mm x 70mm in length 26650 – A...

Why does my damaged battery wrap need to be replaced? Before we even start re-wrapping it's vital to understand how the batteries we use are designed externally from an electrical perspective, and the inherent safety concerns. Apart from the positive terminal at the top, the entire outer...

mAh (milliamp-hour) - The run-time capacity of a battery. One mAh is equivalent to 1/1000th of an amp hour, 1000 milliamps is equal to one amp. So for example a 3000 mAh battery has 3 amp hours, meaning that it can provide 3 amps for 1 hour, 6 amps for half an hour etc. A real world example...

There are a number of reasons why your tank atomizer might leak, so it's helpful to understand the mechanics of how a tank works. The content of the tank is a column of juice suspended above a wick, which acts as a conduit to the coil. The flow resistance of the wick material and the negative...

The simple answer: Too much juice on your coil. Then when the coil is heated (crackle) bubbles of superheated vapor will violently expand outwards (pop) and in the process throw hot droplets of liquid into your mouth hole (spit). What do I do about it? The simple answer: Reduce the amount of...

A much asked question amoung new users specifically of regulated devices (variable wattage) is "what coil do I need" or "what resistance is best for wattage X, and what wire should I use?". The answer to the first question is, whatever coil works best for you as long as your device can supply...

This is not based on any kind of research, it is an educated guess based on circumstantial evidence and some science. As you pulse heat your coils, a layer of insulating oxide forms on the outside of the wire. This stops the electricity from taking a shorter path across any given loop where it...

1. Only buy quality batteries of known CDR (continuous discharge rate) and correct chemistry from reputable vendors. The CDR represents the number of amps that a battery can deliver continuously without safety issues. As well as creating a ‘green’ usage band, it is relevant in the case that your...

Ohms law can be confusing or even intimidating for those of us who are less than comfortable with maths. The good news is there are only three equations that are pertinent to vaping either mechanical or regulated devices. It is vital to how many amps your device and setup is drawing from your...
