So I've finally relented (it was just too shiny), and bought a booster for my tornado tank.
Do any of you guys have one, and are they recommended?
The reason I got one, is because when I change batteries, the vapour is much better for about half hour,
then drops off.
I'm hoping the booster solves this drop off, as I have a USB passthrough in my car,
and that is always a good hit, I'm assuming as the battery is at optimum charge?
