Lighter Adapter?

[Freshco]

I'm a little confused with the volts and amps or whatever. I'm completely electric illiterate. I bought a car-lighter adapter, thinking I can plug in my pass-through for on-the-road vaping, but was highly advised against it for risks of frying out my PT. I was told that I could use that adapter for the PT that has an in-line battery, but not the PT that's a straight shot. Jeffery at WordUp explained to me on the phone, in full detail the reasons why and what volts/amps or whatever, to look for when buying the correct one. I understood every word, but obviously it didn't really sink in because now that I'm looking into it, I'm all confused. Guess I should have taken notes!
Anyway, would somebody please be so kind as to explain what car adapters are to serve what purpose in combination with PT's and charging?
Thanks in advance!
Forgot to ask, can I use the eGo wall charger for either of the PT's, or is that a special wall charger only for the eGo?

PS Kudos to Jeffery (@WordUp) for outstanding customer service!

You'll want one with at least 1000ma and 5v.

I have a truck, so I had to purchase a 12v unit to work in it (but it will work in your car as well!). It has a double usb port. I bought it at Walgreens!

VaporKings sells a $13 Car cigarette lighter to USB 5V 2000mAh adapter. [Actually, Rob at VaporKings meant to say 2000 ma, i.e., milliamps. Milliamp hours has nothing to do with it.] [EDIT: I see that MadVapes sells the same thing for $9.50.] It will work with any PT out there.

As for the eGo wall charger, I assume you mean the AC to USB wall adapter into which the eGO Fast USB charger can be plugged. It could be used with other USB chargers, but not with PTs. madvapes sells a 2 amp AC to USB Adapter, "ideal for passthroughs" for $9.50, but currently is out of stock.

IndyVaporShop sells a different model (that does the same thing) for $10. It is in stock.
