Best Compact GaN 45W Charging Brick for Steam Deck?

I currently use Kogan's provided 45W charger for my Steam Deck OLED but as it's not GaN I find it very hot to the touch, to the point that I would never charge it out of sight as something might just catch on fire.

I've got some spare $$$ now and I'm looking for a 45W GaN charger that's as compact as possible and won't overheat. Budget would probably be in the $50 mark.

I'm an OzBargainer so of course I have a few 20, 30 and 140W chargers lying around for different purposes. I now need one for the purposes of optimally charging my Steam Deck at 45W.

It would be great if the charger also fit in the cavity behind the Steam Deck case that came with the OLED. I have a JSAUX Mod Case but found the extra weight it added to be unruly, so I stopped using that and went back to the default zip case.

Thanks in Advance.
