The Guide to Beat the G-Pen The EgoCron v1.0 First off we'll start with a little introduction as to what this is about. A few months I purchased the G-pen as a discreet way to medicate and consume BHO. I had been using a Healthstone Inner-Cooler vapor pipe previously before the G-pen for my out of home medicating. So after owning the G-pen for a decent amount of time I began to love it although one thing bothered me. The amount of BHO/wax/dabs it could hold/carry was very disappointing after one's tolerance grows. The point of the G-pen was to be discreet but attempting to load a G-pen is anything but discreet and or easy especially if you are working with crumble type wax. I made this vape pen combo in order to solve this problem of having to constantly reload the G-pen. My buddy had an omicron and I loved the fact it could hold a good amount of oil but the battery on it sucked! So here's a guide basically to build IMO one of the best vape pens around. Ego C twist battery. (adjusts all the way from 3.2-4.8) Joye eGo-C Twist Variable Voltage 1000mAh Battery Omicron Extract Cartridge â€¦. I've fit up to an 8th of oil in it and the 2.4ohm is ideal for the type of battery Vaporizer Extract Cartridge Single - PlanetVape The fill tool for the omicron cart (not needed but definitely recommended) Cartridge Fill Tool - PlanetVape I got my mouth piece from the local e cig store but they have them available on planet vape for a little more. And last is the thread adapter to make the cart and battery fit. Also remember to order SLOTTED for air flow. Adapter - 510 Battery to 601 Cartomizer (Omicron, Super Nova, Smoore) So its around 55$ ish without shipping costs. Not too bad seeing as the omnicron retails over 120$ and the Gpen 80$ oh and also idk if anyone vapes nicotine but there are nicotine carts with 100's of flavors. So i just switch the carts and keep the same battery and bingo. Hope this was interesting atleast...enjoy!
