USB 5.0v - to 6.0v step-up adapter - will this boost a passthrough?

[Valhalla1]

dealextreme sells a "USB 5.0V to 6.0V Voltage Step Up Dongle" for $2.55
supposedly for charging nokia's from your computer which accepts 5.7v but not a standard 5.0 usb charge

I was thinking of getting one to use with a usb passthrough for 6v vaping, anyone know of a reason I shouldn't ?

it looks like the ma is too low around 400ma amps is very important when it comes to PT... I wouldn't advise using thisfor your pt especially hooked ot your computer....
