I just want to say a BIG THANKS to PowerBastards High Output Alternators. Another company made me a 250amp and it came built with the plug on the wrong side and ghosted me🙄 Their loss. I'll be going with you guys for all Alternators going forward.🫡
Rock steady voltages at high amperage draws!

There's some negative reviews out there, but you're going to mostly hear only from the guys that had an issue. I bought this over 3 years ago, it was sitting on the shelf and JUST got around to installing it when my OEM alternator failed this past weekendread more! It was amazing to have the part needed on-hand and to have the upgraded output +100A over the OEM 150A unit as a result! I knew I was going to be in "uncharted territory" if I had a problem but I wanted to provide my unsolicited feedback and say that it works perfectly, I haven't had a chance to use a clamp meter on it but the voltage is steady as I turned up the stereo and flipped on every heated accessory I had (including a 600w heated windsheild). It was VERY impressive to me!
It works great

This unit works great to run my 50a DC-DC charger for the lithium batteries in my travel trailer! Even charges the trailer batteries at idle.
More power

Just wanted to thank you again for the help and quick turnaround earlier this fall on the Toyota Pickup alternator. Helped us get a troublesome issue repaired.
You have a favor on the books at Vintage Air, let me know if there is ever something we canread more help with.
Best price and the only high amp alternator manufacturer for my vehicle.
