3.7 or 5v usb pass-thru?

A 5v passthrough usually dose not contain an internal battery. It can reach 5v because there is no internal resistance and pulls max power from the usb port. On older computers and off hubs it may even pull less than 5v if the port itself dosent output that high. At 5v a 2-3ohm carto or atty is appropriate. The lower the ohm the hotter the vapor of course. I enjoy 3ohm at 5v.
The safest way to run a 5V is a 2000mah wall wart. Most computers don't have the output power to supply a 5V PT...and some folks don't know how to check their computers so it's safest to run it off the wall wart. For 5V, standard resistance (2.8ohm and higher) is best.
3.7V PT's can be ran from the USB ports safely. For one of these, I use LR cartos.

I read somewhere that USB pass-thru can damage your PC, is it right? can anyone confirm this?
I built my own (computer) so I know it can deliver, and use my eGo passthru on it almost constantly.
But even if your PC isn't putting out the volts you need it shouldn't effect the PC, just the PV performance.
I could be wrong, if so someone please correct me.
And if in doubt, listen to hairball (she's VERY smart
)

When using a PT on a PC your creating more draw on the power supply, the mobo, the resistors on the mobo, and usually the first to fail the solder points on the mobo were your usb port connects
I guess having a higher output power unit helps. I built PC myself and installed 500W PSU, hope it will be enough.
First post woooo!
I know lots of people are using their computers and I bought my SO a passthrough for xmas but luckily I found from lurking on here that running it off the comp is not a good idea so I also bought an AC to USB adaptor and a USB extension so he can use it without danger to his beloved PC.

It's best to run your PT through a powered USB port that provides 2+ amps
I suggest the 5v PT for one simple reason, you will find that one SR (3ohm) carto on a 5v PT will out last a box of LR (2ohm) cartos on a 3.7.
The way I look at it, my 5v PT was free, paid for by the cartos that I haven't tossed in the trash.

So does anyone know if a usb/battery combo will still work as a passthrough when the battery dies?
Not sure about others, but I have a Joye passthrough with an in-line battery (360mah), and I just tried taking the battery out .... nada. Maybe a dead battery would complete the circuit and it would still work, but I don't have a deady to try it with.
