Mine's usually on a cheap in-line timer, so it's ready to go when I get home and shuts down after I go to bed. The upside to the big heat exchanger is a steady temp. Heavy and quickly repeated hits don't faze it. The Vapolution battery pack will run it, but obviously you get more time if it's preheated at home and switched to the BP or car adapter.

I have the herbalAire too, and it does heat up fast, but the reality is that I can get home, sit down and vape a bowl in the PD before my wife can get the herbalAire turned on and a bowl loaded. And as efficient as the herbalAire is with processing herb, the PD blows it out of the water in that department. It's just amazing how much vapor you can get out of such a small bowl.

How long does the BP keep the PD warm if you preheat it at home?

I use my PD to vape before class, but some classes run up to 5 hours, and I'd love to have it hot and ready in my car for me for break-time, you know?
