Vaping and driving - passthrough and generic mobile charger?

[toth]

So, I'm on the road alot in my work.
I usually bring my trusty SMOK ego PT. However, 900mah doesn't last the long drives, so I tend to plug it into the mobile charger I've got in the car, which has 12V input, and 5V 500ma output. I do feel the vapor changes when I plug it in, feel it increases a lot. Am I right, or is it just my imagination?
Is the battery limiting the output to 3.7, or is the 5V from the charger literally passed through directly to the atty? And if so, is this bad for the battery, or is it made for that type of use? I don't know the Voltage of my computers USB's, so I'm not sure wether it's the same..

From what I understand...and correct me if I'm wrong...wouldn't be the first time, but there are one of two possibilities.

It's either actually supplying 5v or a lot of 3.7v batteries only put out 3v-3.4v for whatever reason and your passthrough is outputting a true 3.7v.

That's exactly what I'm wondering - Is the carto getting 3.7 or 5.0? And if it's getting 5.0, is that bad for the battery? Does the current actually pass through, or more like around?

You'll have to use a multimeter to determine your output voltage. As long as the battery isn't getting dangerously hot it should be fine.

It's my understanding most battery passthroughs are not true passthroughs and only use the battery to fire the atty/carto. When plugged in, it will charge the battery in-between vapes and shut off the charging when firing the atty/carto. I'm not aware of any that function as a true passthrough and put out 5V when plugged in and 3.7 V when battery only.

What you may be experiencing is that since the battery is getting a fresh charge, it is able to pump out a higher voltage closer to 3.7V than when the battery is almost dead and pumping out less voltage.
