The perfect heating element for your Dynavap just got better...and portable. This plug-in heater has a built-in battery for portable use. The same sensor as the Apollo 2 activates even heat to your Vapcap, ready for use in 5-8 seconds. With a built-in cooling magnet, this device is perfect for sessions of .5 a rip or 5 bowls. Say goodbye to refilling your torch (or having to look for it between couch cushions).
