Indeed. Quite convenient, except that of course it has a cable attached. But for driving, or sitting at your computer, it's great. Vape on, without using the battery up and charging it at the same time.

This battery will discharge to I believe 3.3 volts and then will not fire. That way, you don't deplete the battery completely, which I guess is not good. So what I've been doing when not in passthru mode is vape till it quits, then while charging use my old Twist as a backup. This one only takes about 2 hours to charge, so the twist doesn't get used as much, which should help it last longer as well.
