12 v compressor that will actually deliver 120-150 psi?

Hello everyone, my name is Mark and I live in the California central coast area. I decided to put an locomotive style horn on my truck, but did not realize that the 12v compressors that claim 150 max. psi will not come close to that.
I would like to try a $150 horn from amazon that has a good sound on a demo video and many mostly good reviews.

I purchased 2 of these Olarhike compressors and running them in tandem was able to get 78 psi into a 5 gal tank. https://www.amazon.com/OlarHike-Cylinder-Compressor-Inflator-Inflatables/dp/B0874G965F/ref=sr_1_4?crid=DQVLOER11W76&dchild=1&keywords=12%2Bvolt%2Bair%2Bcompressor&qid=1633315677&sprefix=12%2Bvolt%2B%2Caps%2C418&sr=8-4&th=1 I saw the post that suggested using a viair compressor but many of the comments were not favorable and I was wondering if the same thing is true about them not delivering the advertised psi. Wondering if any actually do, and if I could get a decent sound with only 78 psi?

Oasis 12V compressors will deliver 200 psi

Thank you! I will check them out!

I have a pair of Viair 485C Gen2 compressors and they fill two 5 gallon tanks to about 205psi with no problem.

Anything from ViAir, AirMaxxx or Oasis will deliver what they’re rated for

Can’t really speak for anything else on the market
