New Harbor Freight 4000 Watt Predator Generator

HFT 4KW Generator

A couple of years ago I bought a cheap 800 watt HFT generator. The whole $79 generator experiment didn’t work out so well. After the first one seized right out of the box and the second one died and wouldn’t start after only a few months I was ready to give up. Unfortunately, I had promised to have my generator available for some volunteer work the morning after the POS died, so I really didn’t have much time to think things through if I wanted to meet my commitment. Like a sucker, ran right back to my local Harbor Freight store and talked myself into a 4 kW peak / 3.2 kW running generator. I’ve had it for a year now and I have to say I’m impressed. This line of Predator generators might just be a winner for Harbor Freight.

First Impressions

I brought the generator home, opened the box, poured in some gas, and then something happened that I never expected. The thing started on the first pull. Seriously. One pull. My wife said the look of shock on my face was priceless. The Predator generators, and indeed all the engines Harbor Freight sells, are widely described in Internet forums as copies of Honda designs. If they are, they did a good job copying them, because first-pull starting has always been a Honda hallmark.

Once the generator was running everything else worked fine. It was reasonably quiet and seemed to handle the limited loads I gave it on its first run with no problem. I let it run for about thirty minutes and shut it down. The next day I took it to work and it started and ran fine while powering electric sanders, saws, and other tools.

Ongoing Performance

Over the last year I’ve used this generator for a variety of projects, from powering a vacuum in the driveway while cleaning cars to running an electric shredder for leaves and small branches. The shredder pushed the generator towards its limit, but the unit handled the sudden load without trouble. Although I didn’t break out an oscilloscope to look at the power, the basic measurements with my multimeter showed that the generator was holding voltage and frequency even as the load varied. Can’t really ask for more than that.

Other Notes

This generator, like most, provides a variety of outlets, including 4 110 V sockets. But it’s important to understand that these outlets are actually each providing one half of the generator’s center-tapped 220V output. So each 110V outlet bank can actually support only ½ of the total wattage of the generator. Thus one can only power 1600 watts per 110 V outlet, not the full 3200 watt rating.

Otherwise, this generator has continued to provide reliable service, easily handling the odd jobs and loads that I’ve thrown at it. It still starts on the first pull every time, even after sitting for a month or more between uses. I did buy the optional wheel and handle kit and find them pretty valuable, though the handle could be longer – I’m 5′ 10″ tall and when I drag the generator behind me I am often bumping the back of my feet into it. But they are sturdy and useful for moving the generator around.

Final Words

I am not using this generator to power a house or to run appliances during a power failure – I have a 12 kW Kohler for that – so I haven’t tested the total runtime of this unit. But for the odd jobs I need, it works great. Interestingly, Consumer Reports rated generators recently and the Predator line did pretty well in their tests. You need to be a member to see the review, but the overall ratings of the Predator model they tested were near the top of the rankings even if the price was well below the competition. I was impressed. Notably, the generator got high marks for power quality.

So after a year I am much more impressed with this little unit than I was with the 800 watt generator. I recommend you check it out if you’re looking for portable power.
