This RAREELECTRICAL 12V 20 Amp Permanent Magnet Alternator has been sitting on my wishlist for a while, mainly because I needed a reliable replacement for my John Deere machinery. When I finally got it in hand, I was immediately impressed by its compact design and sturdy build.

At just under 2 pounds, it feels surprisingly solid, especially considering its lightweight nature.

The first thing I noticed was how easy it was to install. The compatibility with brands like CAT, KOMATSU, and Yanmar made it straightforward to verify fitment using my OEM part number.

The closed-back design feels durable and keeps dust and debris out, which is a big plus in my dusty work environment. Once connected, the 12V output and 20 amps provide a steady, reliable charge that keeps my equipment running smoothly.

Using it, I appreciated how quiet it runs compared to older models. The permanent magnet setup delivers consistent power without the usual whine or vibration.

The lightweight design doesn’t compromise on strength, and I had no trouble mounting it securely. It’s a solid choice for anyone needing a dependable alternator replacement that’s easy to swap out and fits multiple engine types.

If I had to nitpick, the only downside is that you need to double-check your OEM part number to ensure proper fitment—miss that, and it’s back to the drawing board. But overall, this alternator offers a great balance of performance, durability, and value for the price.

Unboxing this alternator, I immediately noticed its solid build—heavy enough to feel substantial but not cumbersome. The pulley spins smoothly in my hand, and the mounting points line up perfectly, which is a relief after dealing with some cheaper alternatives.
