chargers

Hey everyone, I have a Mavic 3 and Air2s, and I was hoping to find an aftermarket multi charger that would service both types of batteries. Perhaps with an interchangeable wiring harness using the appropriate connectors for each battery type? I've been searching the interwebs, but no luck as...

I will be spending a lot of time in a car while on vacation next month. Is it okay to use a basic cigarette lighter usb charger to charge my Mini’s batteries and rc? If it is okay to use them is there a particular charger someone could recommend.
