Very nice generator

I bought this GP7500E to replace an old Coleman generator I had, and I'm very impressed. It's quiet, it assembled easily (install the wheels, install the handle, hook up the battery, add oil, add gas, and done!), and it powers up my house easily. Here in Nova Scotia power outages have become so frequent that a generator is necessary. The only thing it won't run is my electrical baseboard heating, but no generator even approaching this wattage or price range will do that.

99% Happy

This generator was easy to assemble and fired-up immediately. Quieter than I expected based on neighbors' units and some of the chatter online. Easy to move the generator around. The 1% unhappiness is based on the difficulty to add the oil. The generator is designed to receive oil at an almost 90-degree angle, so you need to spend a crazy amount of time carefully adding little amounts at a time or go buy a funnel with a flexible line. Also, the oil supplied does not indicate the type/weight of the oil and neither does the generator's manual. You can find it online at generac.com FAQ section. It's easy to see why it's an FAQ.

RS8000E PowerDial Portable Generator

Purchased this Generac, after a series of power outages, at a major retailer. (I had gotten quotes for over $10k for a 20 KW standby whole house Generac Gaurdian Series with a 46 week lead & install time). Put it together and had it running in 35 minutes. Although it is bulky and heavy to move around, we have it stored in the garage until needed. Had a Electrician install a plug outside and tied it into our breaker box with an interlock. Our test seems to run everything that is needed in our 1,850 sq ft home. Very happy that for about a total of $2k, I can deal with lugging the portable generator 60ft to our spot to plug it in. Love the electric start and plan on monthly 20-30 minute running test! So far very happy with this set up! Now for the real test of losing power!

Satisfied so far

We have all our permanent electrical work complete (wiring, lockout, receptacle, etc.) and are ready for an extended outage. Recent -30F temps and some local power outages got me concerned since all my heat sources need some electrical energy. Of course I hope to never have to use the generator. The unit looks good to me and the setup was simple. I'm debating whether to fuel and start the unit knowing I then should run it once a month to avoid fuel problems.

Good Product

I bought this electric start Generac Portable generator for its Electric Start Feature. I have owned a Generac Non Electric Start Model for approximately 10 years and have been very satisfied with it. I bought this model for the Electric Start feature. I wish Generac kept the previous style handles which were separate and could be easily locked into position with the spring loaded pins. The new model uses a pin on a cable which is harder to use and flimsy. Also I do not know why Generac placed the Sticker with the Serial and Model number just below the generator motor with about 2 inches of clearance with the frame making it very difficult if not impossible to see and photograph. I had to lay on my garage floor in the cold with a digital SLR camera to photo the serial and model number and did not get the quality photo I would have liked. The Serial and Model Numbers could have been easily seen and photographed if the sticker was placed on the opposite bar of the frame which has plenty of space to be photographed which I do in the event of theft. Other than the handles and the sticker I am very pleased with the unit.

Terrible warranty/parts service

I have had this machine for about two years. I am giving Generac one star because their customer service and warranty repair is very poor. I was not able to acquire a warranty part from the factory. My dealer was not able to acquire the warranty part from the factory. I could only find one repair shop that was willing to do warranty work for portable Generac, generators, and they took six months to repair my machine because Generac did not quickly supply them with the warranty part that they needed to repair my machine.

This product has great features

So far I only have had it for a week. It is smaller and lighter when moving it around compared to my old generator. I am slowly checking out all of the cool features it has. I especially like the ability to charge the battery just by plugging it in. and the light that will show when the battery is low. Larry

Great features!

[This review was collected as part of a promotion.] I received this generator for my honost review. I’m so glad I did because This generator is perfect! It has the capability of powering a lot of items at once! It does have some weight but is super sturdy. It has an electric start. A cradle for easy moving. It does have some noise while running but nothing outrageous! Very nice to have!

Good product

Bought this as a replacement for a Coleman 5500 Vertex that quit producing power. Assembly was straight forward for the wheel kit and handle. Started right up and is noticeably quieter than my old unit. I like the pull cord backup if the battery is dead. Its also nice that is has a fuel gauge. My complaints are the non-charging engine so the battery is only charged from the included 120 volt charger. The other complaint is the electric start switch is on the front panel of the unit and the choke which you have to set before starting and then adjust/turn off upon starting is on the end of the unit. Either move the switch near the choke or add a choke adjustment cable pull on the front panel.
