Mine is on order, they came up for $15 again. But I have this one I got off of Ebay and have been vaping for 5 days now and the battery is at 3/4 on the charge.
I tell you, you add one or two of these things with a few usb pass throughs (upt's) and a usb car adapter, the original batteries are used very little if at all. Plus, at home, I have the upt's plugged into a pc and laptop and can move around between all of them (once my power pack goes dead).
My original intention was to use this power pack 24/7, even when I'm out and about, just to see how long it lasts, but I just keep it in my pocket while shopping, working in the garage, fishing and everthing else.
I don't know when I would use the original battery again?????
Man, this thing is still going, what is it, 11 days now? And it's still at 1/2 charge?
I am waiting for it to go dead so I can use my APC to see how long that lasts.
Again, I'm sucking on this thing a couple of time every few minutes throughout the whole day, so I can't imagine that I'm vaping any less than a normal person.
So there's my update. I will let everyone know when it's dead.
