Our automatic Vapor King e-cigarette USB passthrough is a wonderfully convenient, USB-powered way to enjoy your V4L cartomizers while on the go. 

Simply plug the USB connector into a power-supplied connection on your desktop PC , laptop, wall adapter, or car adapter, then screw on a cartomizer and vape!

No worries about having a charged battery, because the USB passthrough draws power directly from the source. 

This USB passthrough works with most USB ports. It features a durable, reinforced wire connection and the convenience of a partially coiled cable—far superior to the standard KR808D-1 compatible e-cig passthroughs on the market.

Automatic USB passthroughs are activated via an internal suction switch. That means hands free operation—just take a drag and enjoy clouds of flavorful vapor!
