usb pass thru question

[mrmom61]

Do we need extra pass thru's like every thing else? How long can we expect a pass thru to last?

If its a 3.7v one, probably - they can last 3 months or 3 days - the wires are thin and easily run over by chairs..I can't tell you how I know this I usually buy just one and get a spare battery as - if you keep it away from chairs - its usually the battery that goes POOF first.
I have a 5v one though (also kept away from chairs btw lol) no inline battery to worry over either and its still going strong.
These are both for a 510 unit though - don't know what PV you are asking about..

I use a regular passthrough (no battery) and a "sit-and-go" passthrough (with an inline battery) for my 510s and my eGo. I like the sit-and-go better since I can just unplug the PV from the usb plug and take my ecig with me. Both cost about the same. I only started about three weeks ago, but I haven't had any problem with either so far. The only drawback to the sit-and-go is the cord is kinda short.

Although they both have USB plugs for a computer, I'm a bit paranoid about this. So I also bought an AC/USB adapter for home and a cigarette lighter/USB adapter to use in the car. I understand that both adapters should be at least 2 amp. I bought my stuff at MadVapes.com. Three orders so far and no problems.

As long as you don't damage the wires, 5v pass throughs should last indefinitely.

the switches can still wear out.....I've had one fail for that reason, another because the wire wore out where it enters the battery casing.....

Oh yeah..Forgot about the switch. How many cycles are most of these little switches rated for at the 1.5 amps that is used?
