The Alternate from Vivant will change the way you think about vaping. Vivant designed the chamber to efficiently accept and diffuse heat. The result is a bowl that evenly heats, maintains a precise temperature, and is energy-efficient. With different temperatures often needed for loose leaf material precise temperature control allows you to customise your vaping experience effortlessly. Selecting the desired temperature can be achieved by using the two intuitive up/down buttons, heating will begin automatically until it reaches that temperature. Once the indication LED turns green the device is ready and will hold the desired temp steady for one minute. When the LED turns red please wait as the device is re-heating and will be ready again soon.The Alternate is powered by a 30 AMP, 18650 battery. Durable and powerful, these are the heavy duty batteries we trust to bring the Alternate to life. The USB port can be used for charging and updating firmware. The Alternate includes a very crafty modular hemp grinder producing a fine grind and attached directly onto the device. Genius!
