HAPPY CUSTOMERS

“I highly recommend US Alternators to any serious audiophile. Daniel has displayed the best customer service imaginable. My hairpins are exactly what I was hoping for. They supply my setup with more than enough power.”

“I love my US Alternator. My 240a is definitely of high build quality. My voltage holds steady under load. Daniel has always been fast to reply with any questions I have and to be honest, I’d never go with any other alt brand.”

“During the whole order process, Daniel kept me very updated about my alt. He responds quickly to all my questions. I’m digging the durable, high-quality parts. I’ll be getting a 2nd alt soon. US Alts is my #1 recommendation!”

“Couldn’t be happier with my 250a US Alt. On my Nendo bc3500 I don’t drop under 13.8v full tilt. I paid a pretty penny to get all the bells and whistles, but it was worth it. I recommend US Alts to anybody. #1 customer service.”
