Description
The Briggs & Stratton 30708 is made with a 389 cc Briggs & Stratton OHV 4-stroke engine that runs on gasoline. It has an output voltage of 120/240V and a running wattage of 5,750W and a peak wattage of 7,185W. The generator has a pull-start mechanism that is common. With a full tank, the 30708 can run for about 11.5 hours at 0.5 load (using about 0.65 GPH of fuel). This is because it has a 7.5-gallon fuel capacity.
Outlets
The control panel has 7 AC outlets: two 120V 20A (5-20R) GFCI duplexes, a 120/240V 30A (L14-30R) receptacle, and a 120V 20A (5-20R) duplex.
Because the 30708 has a twist-lock L14-30R receptacle, it can be used with a transfer switch.If your power goes out, you can easily connect it to your breaker box to keep your home running.Features
The 30708’s control panel has a digital data center that tells you how many hours it has run in its lifetime.
This helps you keep track of its activity and status.The generator has a built-in fuel gauge that makes it quick, easy, and convenient to find out how much gas is in it.For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying.Briggs & Stratton packed the 30708 with the usual paperwork and owner’s manual to get you going quickly.They also included some oil.Mobility
The Briggs & Stratton 30708 is 29 inches long, 21.5 inches wide, and 25.5 inches high.
It has a typical open frame design that makes it stable and allows it to be lifted off the ground.The generator is built to work well outside and in rough places.Even though the generator is technically considered to “be portable,” it will be very hard to move it by hand because it weighs 190 pounds (in the sense that it is movable).Still, because of its wheel kit (dia:10 “Once the generator is on the ground, it is easy to move thanks to its wheels and folding handle, which make up for its lack of maneuverability.Product Videos
We could find any videos of the product at the time of writing. Please search YouTube for any update.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
