Get a 12V inverter and a normal 120V AC fast charging adapter. It seems silly to turn DC into AC then back into DC, but it’s totally worth it when you need a lot of charge fast.
There are 12V inverters that plug into cigarette lighter ports. Some use a wire, and some just stick out of the port.
You can also get “fast” charging USB ports that stick in your cigarette lighter, but they are never as good as a proper charging adapter. Maybe nowadays you can find a real fast charging one now that USB-C fast charging standards are a thing. I haven’t shopped for one in a long time.
Going from 12V DC to 120 AC and back to the 5-20V DC that USB-C provides is very inefficient (both in energy, cost, and space). Just get a USB cigarette plug adapter that can do fast charging. Right now I see a 60W 2 port USB-C one on Amazon for $10.
The 120V inverter only really makes sense if you’ve got other stuff to charge like a laptop or portable speaker that’s not USB.
