I'm a newbie vapor and and am investigating building a mod. I will probably start with a simple box mod (e.g. puck, nicostick) or a pipe mod, but can't help myself from looking ahead. While browsing fasttech, I came across $12.91 1.5A 2*18650 Single USB Output Mobile Power Pack Battery Charger w/ LED Flashlight at FastTech - Worldwide Free Shipping. Wouldn't this be a candidate for a mod by replacing the switch with a momentary switch and the led with a connector? What do you think?
