The Pax 3 portable vaporizer is smaller, lighter, more durable and easily one of the most reliable vaporizers that you can currently buy. The Pax 3 comes with better battery life, a deeper oven for more even heating and four different heat settings now instead of three on the original. The new temp range is also a wider spectrum. 10 degrees lower and 10 degrees higher for a bit more control during your sessions. The Pax 3 also includes the ability to vape concentrates and the ability to pair via Bluetooth to your phone for more precise temperature control, down to the degree!
