Yamaha is known for its great inverter generators, and the EF3000iS is no exception. Providing you with the utmost reliability, this generator will power your needs.

Being able to run for 19 hours, you have so much added convenience. The Yamaha is however the most expensive out of the three. If price is the main consideration for you, the Champion will appeal to you. The Briggs and Stratton gives you a little bit of added value with its extra two outlets, and its run time is 2 hours more than the Champion. Accordingly, it falls in between Champion and Yamaha in price.  To decide which is the best 3000 watt inverter generator for you, we recommend that you take the time to read the reviews on Amazon.
