I'd like to be able to fast charge my phone and charge a laptop in my car using a car charger. Are there any good options for a car charger with USB-C PPS and 45 W PD output?

There are tons of wired chargers on Amazon that boast 45w and higher, until you read the specs and realize they're all 24v @ 2.5A. On 12v systems, they cap out at 3A and only provide a measly 36W (not enough for my Steam Deck).

The only charger I managed to find that actually gives 45W at 12v (11v @ 4.05A) is a plug-in type that's way big.

I get that it likely requires beefier parts to provide the 11 @ 4.05 spec, and that prohibits manufacturers from making 45W/12v chargers that fit the standard cigarette lighter outlet form factor. But why can't someone make a wired charger that isn't the cigarette lighter form factor? I don't need it to fit in a neat little hole, I just want to be able to wire it so that it's not a dongle sticking out of a port.

Does anyone make a wired usb charger that can put out 45W without requiring a 24v system?

EDIT BECAUSE APPARENTLY IT'S NOT CLEAR: I am trying to avoid plug-in type chargers. I'm looking for something surface mountable because I'm limited by the physical space in the location I want to install the charger.

In any case, I just decided to get a step-up converter instead. Easier to pump 24v to a single line than to find a mountable charger that can deliver 45W on 12v, it seems.

EDIT 2: FOUND! This is the first small form factor charger I've found (well, u/eugenesan found) that has a built-in boost feature that'll output 15v despite only having a 12v input. Maybe my search-fu just sucked, but either way, thanks Eugene-san!
