The company Briggs and Stratton offer a range of different generators, including a 10kw generator. Their website will allow you to browse and purchase the generator that you need.
A new 10kw generator can be purchased at AC Tool Supply, Northern Tool, Home Depot or Wise Equipment. Home Depot seems to be cheaper and most area have a store local.
10kw
10kw generators are available for purchase at Home Depot. They sell the Briggs & Stratton models which are known to be durable and dependable. These generators can get you through the worst of power outages.
There are plenty of stores where you can buy a back up power generator. You can check Best Buy, Target, Walmart, Kmart, and Home Depot. They are quite expensive.
If you want to buy a generator cheap, try Harbor Freight if you have one where you live. Also if you buy it during the good season when there are not storms, it will be cheaper than buying it last minute when demand is high.
Multiple generators are when you use several smaller generators instead of one larger one. For example, you might use multiple 10Kw generators instead of one 30Kw generator.
Champion is a reliable make for cheap generators. They're ideal for camping trips (if you find the right one). There will/will not be a warranty depending on which kind of generator you decide to buy.
Home depot sells fairly cheap power generators you can buy either online or in stores.
The least expensive one was a 10kw GE generator and costs $2,898. The most expensive was a 18kw system made by Kohler priced at $4,769.
I bought my power generator from the actual Wal-Mart store, but you can also purchase them online at the site. They don't have many to choose from, but they are all pretty cheap and work great.
10kW = 10,000 watts
