You have to get yourself a Vapcap.
There are no batteries, no electronics, no chargers or wires of any kind. The Vapcap heats up to toking temps within 5 seconds and can be heated by just about any external heat source, be it a jet lighter, bic lighter, candle, solar heater, campfire or stove element.
There is nothing to breakdown or repair, unless you choose the glass model.
The design is simple genius, wonderfully engineered and a stunner from the aesthetic perspective. The Vapcap is modular so all the elements can be switched out for different looks or functionality, like a VonG body for example.
No stirring is ever required. It is extremely efficient with your herb, hash or concentrate of choice. You will not combust if you respect the temperature indicating click. Personally, I have never convicted using my Vapcap.
The Vapcap is the same size and shape of a cigarette and the ritual is similar, so it appeals to anyone who ever smoked joints or cigarettes.
Check out the thread and the website. IMHO, the Vapcap is the most attractive, efficient and easy to use vaporizer on the market.
A dugout called the Dynastash holds your herb and your Vapcap and measures 4"x2". It fits easily in a pocket.
