Use this portable pen-style device to smoke or vaporize dry herbs... Let's skip the formalities and get straight to the point, though: the heating chamber is HUGE. Apparently in the world of vaporizer pens and electronic pipes, size matters. And the 94F can boast about 2 pipe-sized bowls worth. Well... Suppose that depends on the bowl. Quote us on that for now, and then let us know if you beg to differ. That sounds fair.How to vaporizer using glass screens:Place 1-3 glass screens directly onto the heating coil (works best with 2).Grind your herbs and place a pinch or two onto the glass screen. Packing less herbs makes producing vapor quicker and easier.If you're using just 1 glass screen: Begin heating the chamber and start slowly inhaling almost immediately. If you wait too long, you may combust.If using 2-3 glass screens, you'll lessen the risk of combustion, but it increases how long you must heat the chamber.Continuously heat the chamber for 10-20 seconds. You must bypass your battery's automatic shut-off (which occurs after about 7 seconds) by releasing the power button just before the battery shuts off, then rapidly press and hold it againAfter about 20 seconds, slowly inhale. You should inhale vapor (which you can taste and see when exhaling)If you produce combusted smoke, try using more glass screens or powering the device for less timeIf you don't produce any vapor, try using less glass screens or powering the device for longerFor help, check out the tutorial video belowAdd battery and chargerIf you're NOT the type of person that has spare 510-thread batteries littering your closets, this option is for you. Our batteries are longer lasting than most other shops, coming in at 1100 mAh vs 650. If that means nothing to you, that translates to roughly twice the usage time before you need to plug it in again.To charge your battery, screw it onto the USB adapter and insert the USB plug into the wall charger. While the battery is charging, the USB light should be red. When the device is done charging (usually after 4-5 hours), the USB light will be green.To turn your battery on and off, press the power button 5 times rapidly. Hold the power button to power your device.
