I have tried two usb passthroughs and both were terrible. A 3.7 battery literally put them to shame! I am using them with an AC adapter that supplies 2 amps. I got one from madvapes and I was surprised that it didn't work well because I've had great luck with them.
I am thinking about ordering this:
Vapor4Life- Electronic Cigarette: Vapor King Mini Kit, USB Passthru and cartos
Anyone tried it? Any other recommendations? I can't afford to waste any more $$
