Product: Powermax 250 amp alternator commonly sold on ebay
Appearance: alternator comes packaged well, and appears in new condition, very clean.
Performancemost important factor): the main reason for this review is to clear up any doubt in ebay HO alternators or powermax's atleast. At first i was very skeptical as to whether or not it would do the stated amperage or if they were going to ship me a stock alternator and say it puts out XXX amps.
i can start by saying based on my tests it does its rated amperage or very very close. The alternator is advertised as a 250 amp alternator. As of right now i am running a bb2400.1 amplifier doing around 2100rms watts(app.150amps), 400 watts worth of off road lighting(30 amps), hid headlights(app.20 amps), air conditioner, radio, also a hifonics falcon amplifier(app 20 amps). i can run EVERYTHING @ once in my car including system @ full tilt and stay @ a steady 13.5-13.8 volts above idle rpms. So im sure it puts out at least 200 amps as an alternator reaches it peak amperage when it drops to 12.5 volts.
reliability: I have had this alternator now for about 8 months, and is still running as strong as it did the day i installed it.
Overall value: given the alternator cost me 250$, it does @ or near 250 amps, and is still going strong i would say its a GREAT value. Most of the alternators i see from other HO alt. companies run 300+ dollars, and sometimes they aren't more than 150-170 amps. so being able to purchase a true HO alternator for 250$ is a good deal. Powermax also has some for other vehicles that cost even less with same or better amperage rating.
So overall powermax is a great buy, don't be scared to buy their alternators because they are on Ebay. They have great customer service, and awesome feedback and best of all their products are true to their amperage ratings.
