5000 to 6500W Portable Generators.

Westinghouse has a great unit in this size range for solid performance as well as the Briggs & Stratton and Powermate makes a great showing as well.

10,000W to 12,500W Portable Generators.

On this top end there a couple of players. You should be good with any of them, however, I’m really liking what I see with Generac. Given the past issues with DuroPower machines, just make sure you understand that you may be working against customer service for repair or parts.

Generac 5802 XG10000E 10,000 Watt 530cc OHVI Gas Powered Portable Generator with Wheel Kit & Electric Start
  • With only about a dozen customer inputs it’s getting a 3.3 of 5 starts. Seems that a few had trouble using the customer service and getting it to start. which is atypical of the majority of information for Generac machines. Seems amount of gas in tank for first start is a significant requirement.
  • Typical Load Range on continuous basis 5000 to 8000W
  • 10,000 Rated Watts/ 12,000 Surge Watts

Typical uses: Whole house emergency backup and light commercial operations. Heavy construction site power requirements.

Key features: Engine is like small heavy duty automobile engine for up to 4 times longer life, Has electric start. Service intervals twice as long as other typical units in this size range. Taller than other units. 10 gallon gas tank. for 10 hours at 50% load. covered receptacles. Limited 2 year warranty.

Alternates on Amazon:

12,5000 – 20,000W Portable Generators.

Typically you’ll be looking at standby generation in this size level which are permanently fixed for large home or commercial use. Generac Standby Generators are great for this and you can read the review of the 20kW one here:

Generac Guardian Series 5875 20,000 Watt Air-Cooled Liquid Propane/Natural Gas Powered Standby Generator With Transfer Switch (CARB Compliant) More Details at our Generac 5875 review)

  • The Guardian 5875 gets 4.1 of 5 starts and has an excellent customer comment base.
  • Typical Load Range is for being able to provide the 18kW to 20kW you’ll need for whole house operation so count on upto15kW continuous without issue
  • 18kW Natural Gas and 20kW LP Rated Watts/ 23.4 and 26 Surge Watts for 0.2 second surge

Typical uses: Whole house or small commercial building standby generation.

Key features:
Self contained unit with small foot print of 4ft long and about 2.5 ft sq. Well installed for quiet operation and unobtrusive styling. Uses a 200 amp service and connects to natural gas or liquid propane. Has automatic weekly exercise option to test operation. Automotive style engine for longer maintenance durations.


Yet there may be a need for portable power. Here’s a portable recommendation in this range. Also see links below for Briggs and Kohler for additional standby generation in this range.

Greater than 20,000W

Generac Standby Generator, 25kW, 120/240V, 1Ph

At this level of generation you are looking at PTO, large diesel and larger standby generators.

Start with the Generac and then check here for Kohler Standby Generators and Briggs & Stratton Standby Generators


These choices are some based on our personal basis, it does pay to read the other user reviews to determine if you have any issues that may hang you up. However, most reviewers have some bone to pick because of lack of knowledge or truly having some issues with customer service. I believe that these choices are clearly the top performers and worthy of consideration.

Lack of power may be an elevation issue where you lose power significantly at higher elevations. Others don’t understand the restrictions on circuit breakers and plugs. Be sure to check out our tips and buyer guide sections for more in depth knowledge to help you get a generator for your gift our own needs.
