    I have a nice generator from this company that I use all the time. This is the best generator I have ever owned. The engine is super quiet and the inverter technology helps keep the noise to a minimum. It has been invaluable for me when power goes out. I love all the outlets and the USB outlet that is built in. I can charge my phone and tablet with the generator and power up my laptop. The fuel tank on this generator is huge so I don't have to worry about running out of gas. This generator is perfect for my needs and I would recommend it to anyone who needs a generator.

    I love this generator for its super quiet operation, parallel capability and durability. I go camping once or twice a year and I am always concerned about the noise of my generator. This model is incredibly quiet and I love that I can use the parallel capability to charge multiple devices at the same time. The durability is also a huge plus. I haven't had any issues with this model, and even though it doesn't have the biggest engine, it is still enough to power my tent and other important appliances.

    I needed a generator for my business, and I couldn't be happier with the product I purchased. I am a small business and I needed a generator that was easy to use and had a reliable engine. This product delivered on all counts. I can easily plug in my laptop, phone, and other devices and run them all with ease. The sound level is also very quiet, so it's not disruptive for my customers. I would recommend this product to anyone who needs a generator for their business.
