The PAX 3 Vaporizer is a powerful, discrete, and easy to use device. Pressing down on the mouthpiece is the only requirement for turning the device on or off and cycling through heat settings. The 3,500mAh battery allows for an average of 8-10 sessions on a single charge and can be completely recharged in about 90 minutes using the included charging dock. The complete kit also comes with a concentrate insert so you can switch between vaporizing dry herbs or concentrates with the same device. This device also comes with a 10 year warranty in the unlikely event that you have any problems.
