Overall Good Generator for the Price

I purchaed the 7500E about 9 Months ago, overall the Generator has been great and very reliable. I only had two issues, the first issue happened 20 hours after initial startup. When the engine wouldn't start due to a valve problem. (Repaired under warranty). The second problem was a build up of Carbon which prevented the engine from rotating. The second problem occured after 959 hours and was not covered under warranty. It cost be a little over $110.00 to repair. Other then those two issues the Generator has been great.

Easy start

We purchased our unit the day before Hurricane Ida hit the LA coast. Our old unit would not start so we had to get a new one. This was the only one available everyone was sold out. I am sure glad they had this unit. It was very easy to assemble. Hurricane Ida hit and the power was out for 10 days. It ran 8 to 10 hours a day and never faulted in any way. It was very easy to start, it ran everything I needed (except to central a/c). I just took it out of storage for the new hurricane season. I checked everything out filled it with gasoline and started on the first pull. Very very satisfied.

Nice generator

I purchased this generator after purchasing and returning 3 Westinghouse generators. 2 generator was defective and the other 1 would not power what I needed. Purchased the generac and am very satisfied with its performance. No issues with this generator. Provides all the power I need for my camping needs.

Good planning will bring a good installation experience

We had three installation quotes and they were all very different configurations. Not many installers know the large portable set up. took longer than anticipated, and research. Once we reviewed the steps it was very easy. Moving to desired location also took planning as this is 450lbs. Good idea to have a battery charger on hand, we needed to charge the battery.

Perfect for us

[This review was collected as part of a promotion.] I've owned two Generac generators in the past (traded up) and always been pleased with their performance. Lately it's been harder to pull a generator for me, so when I found one with a push start I jumped at the chance. You're going to need some help with this as it is quite heavy but assembly was easy and after that I could pull it on my own. We typically run our sump pump and freezers when the power goes out and run a cord upstairs to plug in the fridge and charge our phones/electronics. I tested it out and it had no problem with that load. I'd compare the sound to that of a lawn mower, loud, but if you're inside it's not going to bother you. The start is a breeze, I can't believe all the pulling I used to do. I feel a lot better knowing that if the power does go out for an extended period of time, especially with winter coming up, we'll have everything we need to keep us safe and warm.

Nice and Quite

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

Best generator ever

[This review was collected as part of a promotion.] It arrived in excellent condition, assembling was very easy less than 10mins and worked amazing. I love that it has many functions and can power just about anything. Very useful now that the winter weather is coming and electricity tends to go out.

DeWalt 6500 Series

My review is based on the DeWalt 6500 made by Generac. DeWalt a name that is associated with quality products. No matter if it's tools or a generator. DeWalt is a name that is synonymous in the industry for quality. This generator is made by Generac for Dewalt which also is a name that is synonymous in the power generator industry for reliable generators. The bigger the watts on the generator usage, the longer run time at 50% power before refueling. In other words if you run the generator at half load (in this particular case 2 divided into 6500 watts = 3250 watts) you will decrease the fuel consumption by about half. The generator will not have to run at maximum speed to produce a continuous 6500 watts. That is why if you plan on purchasing a generator, always purchase a bigger generator in terms of wattage than you will need. This will decrease your fuel consumption by the generator and you'll be able to run for an extended period of time on the same amount of fuel. Living in South Louisiana along the Gulf Coast, we experience hurricanes often.This generator will allow me the peace of mind knowing that the size of this DeWalt generator will allow me to know that this generator will meet my most critical needs after my power has been knocked out and knowing that the DeWalt name is behind this generator. This generator will allow me to keep my refrigerator and freezer (packed with seafood) continually working and keeping my family comfortable in the hot and humid Louisiana weather. One thing to remember, when using a generator, plug-in one appliance at a time to keep the generator from spiking. All appliances have a capacitor which kicks in when first starting the appliance. This draws quite a bit of wattage from the generator. The capacitor is used to to start the unit and once the unit is up and running the capacitor will disengage and the unit will be running normal. Once this is accomplished the next appliance can be plugged into the generator outlet. Repeat the procedure for the next appliance. This procedure will keep the generator from spiking and shutting down. This DeWalt generator is packed with many features that makes it practical and versitly for a portable generator. DeWalt uses two words to define their array of products "GUARANTEED TOUGH" and that is the truth!

Lot Of Bang For Your Buck!

I purchased one of the older versions of the GP15000 and have used it in many different applications. Ranging from running out door sound, stage and lighting for various different music festivals I have help run to running an entire 3 BR 2 Bath house with a 3 ton AC unit. The engine used on these generators are easy to maintain and are extremely durable. With a huge 16 US Gal. fuel tank, I have had my generator run as long as 8 to 10 hours, depending on the load within my household, and last me an entire night running my stage setup I have. Love the fact that there is a lift point on the generator to be able to use lifting equipment like an engine hoist to pickup my generator and place in the back of my van to transport. (Generator weighs in over 350 pounds) I also love the feature of having the large inflatable wheels to move such generator around without having to exhaust a lot of energy. Plenty of standard household 5-20R duplex wall outlets (One of the 5-20R duplex outlet is GFI ) to having the mammoth L-14 50A 120/240V AC outlet for large loads. If you are ever in the market for a high power output generator and need it to be portable, The GP15000 and the GP-17500 is the go to power plant.

Great Product

[This review was collected as part of a promotion.] This generator works amazingly. It was packaged well and was easy to put the wheels on it. The wheels make it portable and this is helpful for me to move from garage to basement to house. Runs well and is not loud. Was great to use after the hurricane hit NC.
