It's a really tiny one, with a one cell battery. The problem you'll experience looking for USB-C to charge your RC is that it's not "possible" (You'll need a charging controller on your car instead) since the batteries are usually more than one cell and therefore needs balancing and such. Also when you're charging you're allowing currents up to 5 amps in most common chargers, when I'm in a hurry mine goes to 20 amps, this is above what USB-C is rated for, so you'd have to negotiate the latest 200+w power, transform it to the right voltage etc...
I recommend you give that one up for now, sadly.
Just wish there was something you could plug into an existing charger and go
That'd be my recommendation, my father happens to be a reseller so I've got some know-how :)
