The second generation of the O2 Vaporizer, the Vapir NO2 Vaporizer is truly the next generation in vaporization technology. The Vapir NO2 was designed and created based off the suggestions, comments and ideas that previous Vapir customer’s had indicated they wanted in their vaporizer. Now, the Vapir NO2 is seen to be at the top of its class in the portable Vaporizer market. The NO2 features a standard 1 year warranty. It is easy to use out of the box and heats up fast! It has an internal rechargeable battery. The Vapir NO2 has temperature memory so each time you turn it on it remembers your favorite vaporizing temperature! Unlike the older units, the NO2 now uses a stainless steel encased pure brass heating element that delivers cleaner and better testing vapors, which eliminates any bad taste. The digital temperature control allows you to control the temperature with an accuracy of 2-5 degrees for precise heat control and quality vaporization. The Vapir NO2 Digital Vaporizer allows you to use the unit while it charges! The digital temperature gauge can display both Celsius and Fahrenheit * Compact Size and Easily Portable for usage on-the-go (approx. 8 inches height x 1.5 inches wide) * Most Compact Vaporizers are well of $250.00! The Vapir NO2 is well below $200.00 making it wallet friendly! Most compact portable vaporizers available on the market employ a heating system which is powered either directly by flame (usually using a lighter) or through a butane heating mechanism; this is inferior for many reasons. The butane can be inhaled by the customer, which creates an acrid taste. With the clean flameless heat created by the portable unit customers can now enjoy the true flavor and essence of their favorite herbs without any foul aftertaste! From every perspective, the Vapir NO2 is the portable vaporizer of the future…available today! IMPORTANT: In order for the battery to charge the unit must be powered on (the heat does not need to be engaged just the unit power has to be on).
