What is the most efficient way to charge a USB Type-C laptop in a Tesla?

[IgorAntarov]

Could USB - USB Type-C cable work in that case?
Maybe some kind of 12v socket charger is better?
Should I buy 12v -> 220v converter (Europe)?

Anyone got any experience here? Thanks.

Definitely use the 12V socket. The USB ports are pretty low power.

Thanks. How many watts can it handle? The laptop easily drawing 60 watts from 220v charger.
PS: looking if there are some good 12v->Type-C converters.

I think the 12V socket has a 15amp fuse? This means it is rated up to 180W peak with a practical limit of around 140W.

You want a USB-C PD car charger. 30W will slowly charge most laptops, this 63W beast will be enough for almost all USB-C laptops: https://www.amazon.com/dp/B0711BK418/ref=cm_sw_r_cp_api_i_Cr4tCbNY1VY36 (I've not personally used it, but it reviews well)

It's a 15 amp fuse so the 12v can handle 180 watts peak, 80% of that max to be safe.

First, for those talking about the Model 3 fuses, you are incorrect. The Model 3 doesn't have fuses. Just protective MOSFETS controlled by the computer.

What's the most efficient way to charge, that's a slightly dubious question.

What's the easiest way? A USB Type A to USB C cable.

What's the way to get the most current? You need to find a high current USB C 12V adaptor.

If you are talking about an Apple, that's probably your options. Other manufacturers often can use both USB C and their standard solution. And if they have a 12V adapter for their standard solution, that's probably the best.

Good thing this is a Model S forum.

Easy? Sure, but the USB ports in the car will provide ~10 watts at most. That's about 6 hours to charge the battery in a 13" Macbook Pro. Far from practical.

Agree. The 12v USB-PD charger linked up thread is really the best bet. At $30, a no-brainer.

False. USB-C PD laptops will not charge off a USB-A port, even at incredibly slow speeds.

This is the Model S discussion forum, nobody was discussing other cars until you brought them up.
