Hey depending on your weed it depends on temp.. not hard to figure out before your battery dies.. I start no lower than 365F.. I actually have a question for u.. I own a Mighty (My1st vape ever) & Plenty(2nd vape ever/ 1st desktop vaep, btw Plenty kicks ass).. I see you have a Dynavap, Im actually looking into the getting a vapcap...How would you compare the the vapcap to the mighty?
