One of the most popular, well-known dry herb vaporizers around, is the Pax 3. This Pax 3 full kit comes with a half-pack oven lid, a raised mouthpiece, a concentrate oven attachment, and a multitool for maintenance. The charger is a dock that attaches to the back magnetically. The battery life is great for 7-10 sessions (about 3-4 hours of constant use).
