I tell you guys what, if there's more than one of you in the car or if you have a small car, you'll be needing to crack a window! LOL!

Ever since I can Remember smoking My Regular Cigs I had my window cracked a little bit.
Now That I'm vapin in the car I feel like I have to crack the window still.
I guess I still have that smokers twitch , who knows.

Computer USB ports are actually only capable of supplying 500mA, so since the USB chargers and passthroughs are designed to work with those, I'd conjecture 500mA is all you'd need.

I'm curious if this'll work though and hope you guys report back on your findings

Mine works GREAT on my USB 2.0 Macbook Pro, but wouldn't light up at all on 2 other laptops (which I believe are USB 2.0 as well), so maybe there is some other factor at work? Mac is extra good for vaping?

equaz,

If you look around, you will see many report the 500 mah adapters do not work. Nobody seems to really know why that is; we speculate there is not enough power for some reason. My LEDs got a little red section lit but it just wasn't enough to vape with. The entire LED just wouldn't light up....that's all there was to it.

Others here told me to try the 1000 mah and that worked like a charm so doesn't this seem to speak for itself?

If they're usb 2.0 then that is a mystery... but if they're usb 1.0 then that would explain it, since 1.0 doesn't provide any power at all.

SambucaLu, yeah the evidence doesn't lie, but it sure is confusing. Perhaps there's some other number we're overlooking.

Just as a side note sometimes the USB ports that are on the front of the computer may not work well, as they tend not to have as much power as the ones in the back.

a USB-HUB with external power supply could do the trick.

the multiple usb port hubs have usually a external power supply,
so there will be enough power if all ports are beeing used.

what's left to check is, if each port has a amp-draw limit.
if not there will be 2 amps available on a 4 port hub if only one is used!!!
