Product Description The O-Phos Evod series is our entry level oil vaporizer, it is based on the tried and true ego platform with evod enhancements with the additional Up Tech Modifications that further increase the reliability of the O-Phos battery, from the outside it looks like a standard battery but once you start taking it apart you will see the difference. The first difference is the button which is different then ego batteries but still same as all other evod batteries. The second difference is the self adjusting positive pin that other vaporizers do not have, while this is these differences sets us apart from the competition it is not the last one. Once you further go into the design you will see major differences in actual design and implementation. The O-Phos Evod incorporate upgraded electronics that help it stand out as one of the best and most reliable entry level devices in the essential oil market. This platform features a micro USB charger that allows you to use the unit while it charges and allows you to recharge it using battery packs and or with The Core. The O-Phos Evod Series units now include a non stick jar and a stainless steel dab tool along with our entry level Kiss cartridge. These new cartridges incorporate a ceramic wick that gives you more flavor then other silica wick type heaters, this allows the KISS platform to increase the taste of your essential oils. You can also purchase a Titanium Grade 2 Kiss cartridge to fully take advantage of the Kiss design and receive the cleanest vapor possible.
