Compact and lightweight enough at just under 22 pounds, the Powerhouse 500Wi inverter generator provides clean, portable power that's perfect for campground the campground, tailgate party or any outdoor activity where you need your own electrical supply.
The 500Wi's high-efficiency combustion system produces exceptionally low emissions. A recoil start makes it easy to power up and a convenient fuel primer bulb and manual choke ensures a fast start. Choose the variable speed setting to reduce engine noise and save on fuel costs or set it to constant speed when 100 percent full power is needed. Other features include an internal circuit breaker, emergency stop control, spark arrester, and a convenient carry handle.

This inverter generator has one 5-20R 20-amp duplex receptacle. It's backed by a 1-year consumer warranty and a 6-month commercial warranty, and it's EPA, CARB, and CETL compliant for use across North America.

Where conventional generators produce a single square wave of AC power for every engine rotation, an inverter generator produces a clean sine wave just like that power from your home outlets with hundreds of overlapping AC sine waves per engine rotation that results in more electrical power produced from each rotation. The electronic processor in the inverter module "converts" three-phase, high-frequency AC power from the alternator into DC power, which is then changed by the inverter module to a clean and stable 120-volt, 60-hertz AC power signal. The technology programmed into the inverter allows it to control all functions of the generator for stable, consistent, clean power.

This clean sine wave power allows the generator to be used with any and all computer and electronic based appliances in today's homes, businesses, construction sites, and outdoor recreation. An added benefit is the ability of these generators to produce 120-volt, 60-hertz current at various engine speeds, thus saving fuel running at slower speeds and low load conditions but with the power for full speed and output when needed.

Right out of the box it ran but wouldn't put out 120 or 12 volt. I had to take it to a warranty center and they told me it couldn't be fixed so it was replaced. The next one worked fine for about 200 hours and then the economy feature wouldn't work and an hour after that no voltage again. If it got run every day on a week long trip it would start fine but let it sit for a couple of weeks it was hard to get started or wouldn't start at all and I would have to use starting fluid. Also it would have to be very level or the low oil light would come on and shut off even though there it is filled to capacity.
Pros: Quiet, Light Weight, Easy to Store
Cons: Low Quality, Unreliable, Difficult to Use
