Giving the Harbor Freight 800 W Generator a Workout

This entry is part 7 of 9 in the series Generator

In my original post about this little generator, I mentioned that I was going to hook it up to my Bradley Smoker and see if the pair worked well together. I’ll cut to the chase: they do.

Two friends and I headed to the Mid Ohio Sports Car Course in Lexington, OH for the Honda Indy 200 over the weekend of August 4th and 5th. It was a fantastic weekend of racing. But I figured that slow-smoked ribs would be the perfect meal, since I could just set up my smoker near our RV and leave it for 5 hours. The plan worked perfectly.

The generator runs the smoker perfectly.

Right around noon on Saturday I set up the smoker for ribs (12 hickory bisquettes – 4 hours of smoke – followed by my 3 aluminum spacer pucks, oven at 230° F, timer set for 5 hours. I filled the little generator with gas, as much as I could fit into it, and fired it up. At this point it was running the original Bonon spark plug that it came with (#F5TC) because I only had the generator for a couple of days prior to the trip and didn’t have time to replace it. (As a side note – if you Google “Bonon spark plug” you get pretty much nothing except hits about this generator and how people replace this plug with something decent, so who the hell knows how good a Bonon spark plug is.) With the original plug, the generator idled pretty rough but started and ran decently. (I have since replaced it with an Autolite #64 plug from my local Auto Zone store. Others have reported good luck with an NGK #BP5ES plug.) I let it run for about 5 minutes, then switched on the 500 Watt draw of the main Bradley heater. The generator adjusted to the load quickly. At this point I grabbed my Fluke DVM amd took a voltage reading: 110.5 V AC. Great. The frequency was holding steady at 60.2 Hz also. Perfect. I gave the generator a minute or two to get used to the new load and then switched on the additional 150 Watt load of the smoker. Again it took a second to adjust but stabilized again at 110.5 V and 60.2 Hz.

Then I walked away. With my fingers crossed that I wouldn’t come back to two racks of raw ribs because the second generator had seized up like my first one did. My friends and I took off to walk the paddock at the race for the next four-plus hours. The manual claimed that the generator would run for approximately 5 hours on a full tank at 50% (400 W) load. Since I was running at 75% load when the heaters were both on (and only ~17% when the main heater cycled off) I knew it would be less than that. But not sure how much less.

When we came back to the RV 5 hours later I was proven correct – the generator was off and the tank was dry. But the smoker was still holding 210° F, which means that it probably hadn’t been off for long. Maybe 30 minutes was my guess. So I  unplugged everything, refueled, and it started back up on the second pull. I restarted the smoker and let it get the final 45 minutes if smoking in. I noticed no ill effects from letting the generator stop under load.

The ribs were fantastic. And so was this little generator. After my initial failure, this one has probably 12 to 15 hours on it now and it seems to be doing fine. I just fired it up today after replacing the spark plug and it even seems to idle more smoothly now.

So, my initial impressions are still favorable. This little generator seems to be an awesome little tool and has been surprisingly reliable. Hopefully I’ll have more favorable updates in the coming months
