I was at radioshack in the battery section looking for a rechargeable battery pack for my 510 passthrough. I found Duracell makes a compact rechargeable lithium battery pack in a nicely housed slim unit called the instant charger. I believe it's 5V 1150 mah. It has a female usb port on one end and a mini usb port on the other end with an on and off switch and power indicator led on top. Now I can carry this around and have the nice vape out of my passthrough. Radio shack has this on clearance for $20. It would also make a nice back up power for diy's with USB or mini USB connections.

Let us know how well it works with a passthrough. Most of these usually do a good job putting an emergency charge on a cell phone.
Not sure about the reference to a TP. It probably wouldn't give up much charge to a 2600mah 3.7 volt battery.

Well I charged it full, connected it to my pass through, tried an atomizer from my 510 and my new Riva ego and led kept flashing alas no vapor. I guess it's too much resistance. Oh well I'll use it what it was intended for as a back up power source for my iphone.
