How It Works

The ProVari is a microprocessor controlled variable voltage e-cig that lets you adjust the amount of vapor quickly and easily. With the ProVari vapor cigarette you can always create the perfect setting for your atomizer, cartomizer, or e-liquid tank. Our technology keeps your vapor volume the same regardless of your remaining battery power, and you can adjust the voltage from 2.9 - 6.0 volts in 0.1 volt increments.

With its built-in display, you can also adjust your voltage and access additional functions in seconds. The ProVari e-cigarette is designed to be very simple and easy to use!

To adjust the voltage on the ProVari, simply press the button 5 times in a row. The digital display will turn on and you can flip through the voltage settings by pressing the button. Once you are done making changes, the ProVari will automatically save your settings and the display will turn off. You are now ready to vape!

Extend Your Experience

The optional extension cap replaces the stock end cap and allows you to use a single 18650 battery. This will extend the length of the device and offer you longer run times between charging. When purchasing this option you will still receive the original end cap so you can use both battery types.

We recommend only using AW IMR e-cig high drain batteries in your ProVari You must use batteries that have a positive button on the top. Flat top batteries will not work.

Battery Tip

The standard ProVari takes a single 18490/18500 battery. The ProVari uses a special boost circuit to adjust the voltage to your desired level and single battery devices are considered the safest you can own!

Batteries - We only recommend using approved 18490 and 18650 batteries in the ProVari. All of the batteries that we sell on our website have been tested to work with the ProVari and these are the only cells you should use. There is a big difference between all the different batteries on the market and a lot of testing has been done on these various batteries. The reason we recommend using high drain cells is because these cells can output more current providing the ProVari with the power it needs to operate properly. There are a number of batteries that will cause issues including the Trustfire, Ultrafire. These batteries cannot handle higher current output and the battery will turn off while in use or cause a low battery alert much sooner than it should because the ecig batteries have a high internal resistance. Please make sure you get the proper batteries to use in the ProVari to avoid problems.
