The original 510 battery-box PTs are notoriously cheaply made, and all of mine died within a month or two, some taking USB ports out with them. I believe that their internal charger from the port draws too much current, both in terms of normal computer USB port ratings, as well as their own rating! I know Rocky Mountain Vapor stopped carrying them because of all the returns.

There are two PTs I really like and have used for quite a while now: the simple 5V straight-wire PT and the Hello Sit and Go, which is like a regular 510 battery with a USB port for charging. Its working voltage is 3.7V, and it seems to last off-line far longer than a regular 510 battery. The Sit and Go should work with any computer USB port rated for >300 mA, but I use a powered AC/USB converter. And the 5V PT needs an AC/USB converter rated to at least 2 Amps, but it is a great, and cheap, PT.

i got tired of the '5v' passthroughs out there, since if you're using a joye 510 atty (2.2-2.5 ohms, usually) you're pulling as much as 2.27 A, and there's just no way the chinese-made passthroughs are rated for that much (especially considering if your using a standard usb port you're lucky if you get 1 A). i took matters into my own hands and made my own passthrough out of a 5v 3A router power supply (very much like this: Genuine DELTA SWITCHING AC ADAPTOR ADP-15GH B 5V 3A - eBay (item 290372974728 end time Feb-15-11 04:34:30 PST)) and some parts from radio shack (atty connector from madvapes). EDIT: here's a crappy cell phone pic: http://twitpic.com/3pscgj

my only problem now is finding an atty that doesn't leak, but that's another issue all-together. my next build (or purchase) will have a juice reuptake well as a condition. i'm sick of wasting juice on paper towels, shirt sleeves, etc.
