Can components between different brand e-cigs be interchanged?

[GSHARQ]

I own 2 different brand e-cigs.

The first one is the Vapor King eTank
Vapor King eTank - Electric Cigarettes, Cartridges, Batteries for Sale

The second one is this Joye 510

The funny thing is I noticed the charging case for the Vapor King eTank looks exactly like the charging case for the Joye 510. The only difference is one has the Vapor King label on it and the Joye 510 one is blank.

When I put one of the Vapor King batteries into the Joye 510 charging case, it lights up as it's supposed to, so it appears to be charging, but I don't want to damage either the battery or the charging case.

Is it best not to interchange them?

Hey there.
I would not recommend doing this without comparing the output (in mA) of your regular Vapor King charger with the output of the charging case. There is a little tolerance, but you don't want to plug something up that has too LOW of a mA for your device or you will ruin your battery. There is more tolerance going to a higher mA (but your battery will charge AND discharge faster).
You also might want to be careful about polarity, if applicable.

This is how any lithium ion battery works
