The Dragon M401 Passthrough?

[citrusfawn]

Hi everyone! I've been using e-cigs since December 2nd! I love them and I haven't looked back. Now I'm buying one for my friend. Thing is, the chargers on truesmoker is sold out of the traditional usb chargers. How does the passthrough work?? Can it replace a charger?? I've been trying to figure out what the passthrough is exactly, but can't find any info. Thank you!!

A passthru is a battery that plugs into a USB port and draws power from it. No need to charge the battery as long as it is connected to a USB source like your computer. Whether or not it can replace a charger depends on what your needs are. Hope this helps.

My 401 pt doesn't have a battery. I pulls power directly from the USB port. It's definitely my preferred way of vaping. The no battery pt should be providing closer to 5V to your atty. A pt with a battery will only provide the standard 3.7V as your regular batteries, but is just being constantly charged from the USB port.
