Where Can I Get A......? Car lighter adapter

[Freshco]

Not sure if this is posted in the correct area...
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!

Check the adapter's output power rating.

Under 500mA is only good for regular slow battery chargers.

500mA is fine for fast chargers (including ego) and PTs with the inline battery.

2A (2000mA) is required for PTs without the battery.

madvapes is an excellent source for 2A adapters, both car and AC.

Thanks Candre!

Aha! You asked your question both here and in the Ask The Veterans forum. See Hellen's and my answers there.

Most of my answer is identical to candre23's (smart guy). I did add another source for a 2 amp 5V AC adapter, since MadVapes is out of stock on that one.
