Customer Questions & Answers

Customer Reviews

I received the product in perfect working condition.
Less than six months in, and after I started it once a month just to let it run and blow out the cobwebs, the engine seized hard.
Charles Crolley
After an easy assembly and filling with gas and oil, a quick pull on the cord and it started up first time.

The generator was shipped and delivered quickly. Instructions for handle and wheel kits were accurate, and everything we needed was in the box.
Although I hadn't planned to do so, I purchased and installed a six-circuit transfer switch. This generator has more than enough power to have gone with a larger transfer switch, as it turns out.
I love Honda products. Once I put in the gas and oil, I anticipated having at least a little difficulty with the first start-up, but to my delighted amazement, the first pull on the starter rope resulted in a smooth-running engine cadence. A beautiful sound.
I highly recommend this item, and Amazon had the best price.
Best of luck to you all.

The price seems to fluctuate between $1,200 & $1,300, so wait it out if you're able (depending on your likelihood of a blackout). Obviously, after Hurricane Sandy, this and other power-related goods have been long sold out.

My house, along with most others in Northeast NJ, had a prolonged blackout during Hurricane Sandy from downed power lines across the state. While mine was "only" 2.5 days (some coworkers didn't have power for 2 weeks), I'd found that a blackout causes not only inconvenience, but a morbid sense of vulnerability. It doesn't matter if you have a shack or a mansion; you NEED a generator "just in case". It proved to be the case for me within 5 months of owning a home. Ideally, you'd have something like a 20KW Generac standby generator that runs on natural gas (like the typical stove-top) which is automatic and can power the entire house, but it is quite expensive ($10K range) and takes up a lot of outdoor space.

Instead, I have this high capacity gasoline generator with a garage 240V receptable and basement 2 transfer switches for my main & sub electrical panels (10 toggle switches total to manually flip between grid & generator power). Otherwise, you'd need to run a LONG 120V power extension cord (or upto 4 multiple) from the generator to a power strip for each of your appliances, while risking a cord overload fire hazard and leaving upstairs unpowered.

The "accessories" assembly probably took an hour, with most of the time spent looking for the correct size tools and bricks to prop up the generator for wheels, grounding, and handle assemblies. Do the assembly as soon as you receive the generator, since it may take longer than assumed, especially in the dark.

I have read the other reviews so I'll try not to repeat what has already been said, most of which I'm in agreement with. The assembly is pretty straight forward and the instructions on how to do this could be done better. My main gripe about this unit is the wheels. There is no straight shaft running the length of the unit and the wheels on mine tilt inward because (let's face it) with 8 gallons of gas, a generator, and Honda motor, this thing is very heavy. I'm quite certain I will be looking to re-engineer this problem after the wheels fall off, but until that time comes, I'll live with it.

For those of you who don't know this is not an "inverter" generator. Inverters are king of the hill when it comes to generators and they can cost you more than what you want to pay. Honda makes smaller inverters that run quieter because the engines can run variably to the amount of power needed through electronic control. The downside to inverters are their cost and repair cost if that would be needed. In the future I can see inverters being the norm for generators when they get cheaper.

I installed a transfer panel (Reliance) in my home to compliment my new generator. Some tips on transfer panels: make sure if you are thinking of running (and I don't know if this is a good idea for load balance issues) your central AC that you get a transfer panel that has a two pole 30 amp breaker or something similar to that. I didn't realize it at first but the transfer panel I bought didn't have enough 15 amp breakers for my use and too many 20 amp breakers that I didn't really need and NO 30amp breakers. In other words do your homework and check out what you have in your fuse panel to match the right transfer switch that you may need and you'll be OK.

I have had significant problems with this generator. After topping off the oil and fuel, I turned the fuel selector to "ON" and started it up. After about 30 seconds of running, fuel started to pour out of the carburetor overflow. Talk about a fire hazard. It appears that the fuel float in the bowl is not rising or the needle is not sealing properly, allowing constant flow. Additionally, it puts out 134v at the moment, which trips all of my AFCI and GFCI breakers in the house that I have surge protectors on, as they feed back the extra voltage. What ever happened to quality control??? I think my unit went through QC at the end of a Friday or something, based on the other gleaming reviews of this product.

I have owned several other pieces of Honda power equipment, as well as another smaller Powermate generator and have never experienced issues like these.

I called Powermate to discuss the issue, and they stated I would have to take it to a Honda dealer for repair. The closest Honda warranty dealer to me is 45 minutes away, and I'll have to find a way to get it there as I don't have a truck or trailer. Very frustrating. Piece of junk.

*******UPDATE!!! 11/01/2012*******

Amazon kindly refunded the entire purchase price after I contacted them directly on 10/26/2012 after writing this review, and explained all of the issues. A++++ for Amazon customer service! However, I still have to leave a 1 star rating for the product as its initial quality was deplorable. It looks like others have had quality issues with these since I wrote my initial review as well.
