Top Questions

Rokin’s batteries all contain surge protection and have to be connected properly to charge.

For Nitro and Cyclone:
First plug in the USB wall charger to the power outlet.  Then plug in the battery charger to the USB wall charger that is plugged in to a outlet.  Make sure that the green light on the battery charger is lit up before you screw the battery on.  Once the battery charger is plugged in to the USB charger and the green light is on you are ready to screw the battery onto the battery charger.  The light on the battery charger will then change from green to red and the lights on the battery button will flash in all 3 colors.   It should take about 2 to 2 ½ hours to recharge the battery.

Be sure not screw the battery onto the charger before it has power and the green light is lit up.

For Thunder, Mini Tank, and Viper:
Connect the micro USB charger to either a wall charger or a charging port. Then connect your device to the micro USB charger.

The Thunder can be operated while charging.


The battery is out of power.  Please see the question “How do I charge my pen” on FAQ page

Remove the drip tip and drip cap.  Turn the pen to the blue (medium) temperature setting.  Hold the pen upside down over a damp disposable cloth and hold down the “R” button until the chamber is clear.  Wipe the threading if necessary.

The main cause for leaking atomizers is overloading of the atomizer chamber.  Make sure that the material is not up to and in the holes at the top of the atomizer while vaping.  Keeping your pen in the upright position will also help your pen to not leak onto the battery. The newer leak resistant side airflow atomizers should help reduce most leakage.

You can increase the life of your battery by doing the following:

– Don’t leave your device plugged in once it has finished charging.
– Try to keep your battery at room temperature and avoid leaving it in cold/hot places, like your car, for extended periods.
– Don’t run your battery completely down every time. Keeping your battery charged will increase its life.
– Turn the device off when you’re not using it.

The patent-pending Cyclone cooling technology works in multiple ways. First, it contains internal baffles that allow the vapor more time to cool off. Second, it is all made from metal that easily absorbs the extra heat and continues the cooling process. Lastly, the final path for the vapor is shaped specifically to slow down and expand the vapor, giving you the best tasting and satisfying vapor you expect!

The Cyclone battery has 4 different temperature Settings, green (lowest), blue, purple, and red (highest). You can switch through the settings by clicking the R button 4 times.

Cyclone can be turned on/off with 5 clicks and to begin Active Mode click the R button 2 times. Active mode will give you a continuous vapor experience for 14 seconds.

The kit comes with both Quartz and ceramic atomizers with patent-pending cooling technology that screw onto the battery.

We recommend that you replace your atomizer on the Cyclone or Nitro at least every 3 months depending on use. When you notice a significant decrease in performance with no improvement after cleaning, we recommend replacement.

The atomizers are considered consumable and will need to be replaced at some point.

Every cartridge has an expected life span of approximately 4-5 refills. After that point performance of the cartridge may not be as good and replacement of the cartridge is recommended.

Simply slide the front cover that is surrounding the cartridge area, screw in your larger cartridge to Mini Tank, and the slide the front cover back over the cartridge. The front cover is not needed to use the Mini Tank if it does not fit back over.

The EASY FILL oil cartridge makes filling your cartridge very simple. Just unscrew the top of the cartridge and the top along with the entire center pole will be removed. Using a syringe or dropper, fill the cartridge with your product up to or just right below the 0.5ml fill line. Then reassemble the cartridge by screwing the top and center pole piece back onto the cartridge.

Tip: it helps to jiggle the top portion a little when reassembling to make sure no air bubbles are trapped beneath the center pole.

Once the product has been restocked it will be shipped out immediately and you will receive an email. That email will contain your tracking number and order information. If you have any additional questions please contact us.

Make sure that the cartridge is fully ejected. If it’s not fully extended then pull up on it slightly to engage the cartridge, it will not produce vapor unless fully extended. If the Viper still is not working then please contact support.

The Viper will automatically shut off after while if not being used. Simply click the power button 5 times to turn the Viper back on.

To protect the battery and keep it fully charged the Mini Tank is designed to turn off once it has finished charging to 100%. To turn the Mini Tank back on simply click the button 5 times rapidly.
