RELIABLE

Trip planned boondocking for part of it, all is well until it's not! The Sun didn't shine so no solar load. Backup gen wouldn't pick up load. Generac to the rescue!! The iQ5200 worked flawlessly, and saved us!

Beyond disappointing

I bought this a couple months ago. It never worked. The Fleet Farm I purchased it from would not take this product back. The generator is still at a small machine engine shop. I will never buy your products again.

Hurricane Tested

So far, it is running like a champ. Powering our refrigerator, freezer, TV, computer, WiFi and three lamps. Once Hurricane Florence is overand things settle down a bit, we might look into getting a whole house natural gas generator.

Just out of the box and filled with the oil you provided and it started first pull.

An excellent value for the money, I will be using this for power at a remote hunting camp and it is easily portable for that purpose. Looking forward to the enhanced run time an inverter will bring to power generation "off the grid."

Good value for product

Like the size and weight. Easy to move with just one person. It would be great if you added a fuel gauge to keep track easier of fuel consumption when running.

Very convenient.

Bought it after 64 days w/out electricity after Hurricane Maria in Puerto Rico, I am using it for my fridge and the washer machine, and its working great, plus it saves a lot of money in gas. No regrets.

Does the job

Between hurricanes and ice storms, we have power outages about 4 times a year that last longer than 8 hours. I bought this inverter for one reason: to power our freezer!! Does the job and even gives me a lamp or two when it is dark.

Product appears to be well made

Have not used generator as of yet, ( will start up Pryor to hurricane season) but item looks to be well made. Other residents in my community have used this generator during hurricane Irma and were completely satisfied.
