True? USB uses up carts faster?

I have ordered one.

Assume you're talking about comparing a USB Passthrough with a battery to power your PV.

A standard battery provides 3.x volts to your attomizer (the x depending on the model), while a batteryless PT provides (I believe) 5V. So, the later would consume juice faster, all else being equal. It would also produce a better vape by most accounts.

If the PT has an inline battery, as many do, the battery 'regulates' the voltage to less than 5V and you most likely won't notice any increase in juice consumption. Nor will you benefit from the higher voltage vaping.

Not exactly correct. A true PT is simply a power supply adapter and as such the actual vaping volts will depend on the amount of current it can supply and the resistance of the atty.

As an example a 5V@2000mA (2A) adapter will power a Joye 510 at about 4.2V and a SLB/DSE 510 or standard carto (~3Ω) at about 5V.

Those USB battery devices are simply running off the battery, it's not regulating the input it's the battery that's actually firing the atty.
