510 pass thru voltage?

[guitardedmark]

So I just received this 510 pass thru. I was under the impression that this is higher voltage but there is no discernable difference between this and my Joye 510. Anybody know what voltage this pass thru is?

You got the one with the inline battery. It runs at 3.7 volts. The HV PT has no battery and runs at 5v. This is the HV 510 high voltageManual USB Passthrough model. Good choice on ordering from Litecig, they're a great vendor. I'd just order the HV and keep the other as a backup unit.
