12vdc AC Compressor on Amazon, Looks interesting if you have an alternator to run it. Options

Just add Under Dash Evaporator, Condenser and dryer!
Example install, but mine is a Benling

I just ordered the classic retrofit a/c kit. It’s for my ‘67 912 (with a 3.2) but I’m going to check the fit of the blower box against a 914.
Is your electric a/c working?

Not yet.. I still need another fitting and then charge it. I was just surprised to see a 12vdc compressor on Amazon.

Electric AC for autos is the future. No belt to suck HP even when not in use. Just need an alternator and wiring to supply the power. I believe most autos today have E-AC. Likewise the power steering is electric now again, no robbing HP if the assist is not needed.

Not true

EVs yes but they are using high voltage (300v or more) to the compressor. Conventional ICE - no.

Too much power draw on a 12v system.

Look at the spec’s on these 12v electric compressors - in the range of 75-100 amps.

Your average ICE powertrain is not equipped with an alternator large enough to handle that sort of load. Even on something like a F150 with a (huge) 200A alternator, the electrical system cannot support an incremental 100A draw for electric AC.

Might also want to look at the compressor displacement on these units - not very much displacement compared to normal automotive AC compressors.
