The Vapohead 12V Vaporizers are equipped with a special 12Volt plug that is put into a cigarette type lighter found commonly in cars, boats, RVs and other portable recreational vehicles.  This is sometimes called the Vapohead Vapo-to-Go.   We do not recommend this for use by the driver of any vehicle - but just your friends.   Try our Vapo Combo Pak!  Fantastic Value and Savings.  Enjoy your 12V Vapohead!
