Two years later still going strong

I am happy with this alternator I use with my daily driver pushing over two thousand watts in my audio system alone and has not given me a problem yet.
Just what the Ford DR. ordered.

This works great on my Shelby. Send more stickers!

Bought my Fitzall 220 in 2010 and it's still performing as good as the day I installed it. It's been through quite a lot of torture with stereo systems and dust,dirt, mud, water and trails across the country. I wouldn't be surprised if it outlived my Toyota at 300k miles so far.
Thank you

2011 Subaru Impreza…250a alternator…Put this alternator in in probably less than a half hour perfect fit. Super nice and shiny works amazing running a 2500 watt amp with double 15 inch and solid power at full tilt with most electronics in the car on as well handles like a champ I think lowest voltage I got when at idle was 13.6 and that was the absolute loudest my speakers could go definitely recommending this to everyone with a system.
Works exactly as described!

I was a little skeptical at first since I had never heard of this company before, but I decided to purchase this h/o alternator for my Corolla since it's really the only factory-fitting option out there. It was very easy to install and bolted up exactly like the factory alternator. My amp and battery are much happier now, and I stay at a consistent 14.3+ volts while driving with my 800w rms system playing. Thank you power bastards!

3 years and still working
- 5/4/2023
I bought this alternator back in 2020, installed in 2020, here we are in 2023, and it is still working perfectly.
A beast of power!

I have it running two AGM batts, and a high output system, it performs awesomely!
Bimmers should have included POWERBASTARDS

The 240+ amps high output alternator I bought from POWERBASTERS a few years ago is still going strong. Prior to the above mentioned purchase. I had to pull out the original alternator plus thereafter 2 replacement alternators that eventually went bad in 2 years time.
The expense, wasted labor and time I spent removing all those alternators cost me 4 times more then the price I paid for a new higher output alternator from your company.
Three years later the alternator I bought from POWERBASTARDS passes my systems test at 14.19 volts with the headlights on, factory radio on, air conditioner and at the same time charges my very large battery just fine.
Thank You so much.
Bolts right in, plenty of power.

Fits in my 97 NA exact same bolt pattern and wire connectors.

Gives plenty of peak power and it doesn't kill the little Miata battery
3 days so far

Easy install. Plug & play on 2013 Veloster base. Stock alternator kept 14.2 volts on startup. Now upon startup/warming up car I'm sitting at 14.7 volts. Amperage says "220". So far seems fine. This should go well with a second identical battery eventually for a quality 2000 watt sound system. 3 days so far, everyday driver.

No Complaints

I have it installed in a '16 Civic LX. Works great. I power 2 12" W6's and an HD 1200/1 amp. Headlights definitely don't dim anymore.
Great product
- 9/19/2022
I used mine for a very hungry stereo system and it was more than enough power to run the entire system without adding an additional battery
Kick ass power

I installed this Bastard on my 2005 Sprinter and my truck runs much better.
Completly Transformed My Truck!
- 8/15/2022
This Power Bastards Alternator has completely transformed my nearly 20 year old work truck, with over 300K on it! I abuse my straight six Trailblazer regularly as a contractor. Upgrades include a tune, CAI, dual exhaust, and an e-fan, which led me to Power Bastards. These Trailblazers have a heavy electric load with 6 disc bose, dvd, heated seats, etc. The high amp output at idle keeps everything working in top performance without huge drains on the battery. I'm on 8 years on a 5 year warranty battery, in Canada! Increased miles per gallon, idles lower and smoother, instant pickup, and the stereo is louder and crystal clear! Wish i bought it years ago....
Amazing Alternator
- 7/17/2022
Your alternator works amazingly, installed in 15min on my 04 Hummer H2, turned on the ac, lights, and ran my stereo which consists of a combined total wattage of 5800rms. Voltage never dipped below 13.8 at idle for 5 minutes on a full stereo run. During regular use with ac on and lights on, the voltage never dopped below 14.2. Thank you for making an alternator that performs as it needs to and better.
Fast

Alternator was here in 1 day and no hassles what so ever, thanks power bastards.

Even though I didn't talk directly to the staff they where fast on response with the questions I asked when emailed. The product came in an timely matter and was just in time for an competition. Would recommend powerbastards to anyone 10 thumbs up
Thank you!

Thank you so much Mike, I appreciate the great service along with a great quality alternator works like a gem, couldn’t be happier!!!
5 years old and works great

Ran across these while overhauling a loaded 2000 ford e-250 custom with av and a competition stereo in it, rear air, all sorts of odd loads. 5 years later I still recommend this to all my friends. Flawless performance, this car eats batteries as it’s mostly driven short distances, the output at idle and low speeds is phenomenal. No headlight flicker, it never gets overheated even in stop and go Texas heat and traffic with everything cranking. Put one of these in every car you own.
220 alternator

Bought it for my 2002 Avalon and it was plug and play no more lights blinking
Awesome

I received my alternator yesterday on 1/6/2022.
and installed it I've never seen my voltage at 14 until I got this alternator. later on that night I drove it my lights were so bright I thought I had my brights on and I had more power to my amplifiers. I will definitely recommend power bastards to all my friends That's running more than one amp and want that extra power.
Couldn't have been easier

I've had this alternator in my 2017 Subaru outback for close to a year now without any issues. My power needs water for a 1500w aftermarket audio system. The strange thing was with the OEM alternator my lights didn't dim but, my engine RPM would dance to the bass kick, lol. Never experienced that before.

Power bastards alternator was plug and play as described. No more rpm dance, no added noise, quiet, and smooth operation. I had already done the "BIG 4" and a new serpentine belt went on at the same time as the PB alternator.

Also I soon found out that most off not all newer vehicles have a regulated voltage power supply now, so I purchased a bypass module from another company that allows 14.5v-14.8v continuously to the system.
Very powerful, direct fit

I got this for my 97 camry that's probably the loudest camry most people will ever hear. The stock alternator was falling flat on its face at only about half power and this thing has no problem! I would say it puts out 110A @ idle. This alternator switched right out with the stock alternator no problem. Overall, very happy with this alternator and hopefully it lasts longer than stock
Great product
- 10/14/2021
Does everything as advertised and more. Wonderful product made in the USA. Great support and wonderful to deal with!
Very quick delivery & product fits perfectly.
- 9/10/2021
no problems sliding the new alternator in.
It worked flawlessly out of the box. The Quality control is fantastic. My headlights do not dim anymore. Plenty of power for my amps.
So far so good
- 8/20/2021
Easy install only took about an hr. Went right in where my old one was mounted.
Haven't really put it through the paces yet or really tested it as I recently had a minor wreck in that truck, which messed up my bumper and turn signal so I'm just kinda letting it sit til I get that fixed.
I will come back and give another review soon as I really get a chance to test it out fully.
Thank you Mike!
That was a pretty quick turn out too from time of purchase to the time it was in my hands.
Much more power

Great replacement for our 2000 Ford E-250 custom van. 3 years running and provides all the energy this multi battery with competition quality sound system and full AV setup.
Highly recommend.
Awesome Product!!!!!!!!
