Keep your lights on, your food cold, your family connected – and more – during a power outage.

Zoom on the Briggs & Stratton 30708

In a few words, the Briggs & Stratton 30708 is a portable generator perfectly suited for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to be able to deliver results, even during a power failure

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

The Briggs & Stratton 30708 houses a 389 cc Briggs & Stratton OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5,750W along with a peak wattage of 7,185W.

This generator utilizes a conventional pull-start mechanism for startup.

With a fuel capacity of 7.5 gallons, the 30708 may run for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.65 GPH).

Outlets

The control panel features 7 AC outlets as follows:

Two Duplexes 120V 20A (5-20R) GFCI
Duplex 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle

With its twist-lock L14-30R receptacle, the 30708 is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.

Portability

With dimensions of L29 x W21.5 x H25.5 in, the standard open frame design of the Briggs & Stratton 30708 provides stability and easy maintenance access to components, as well as good air circulation. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 190 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the Briggs & Stratton 30708

The 30708's control panel

Included in the control panel of the 30708, a digital data center assists in tracking its status and activity by providing details on the lifetime run hours.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

In addition to the standard documentation and owner's manual (opens in a new tab) for prompt setup, Briggs & Stratton has also included some oil in the packaging of the 30708.

The Briggs & Stratton 30708 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Briggs & Stratton 30708 compare to generators of similar power (between 5500 and 6500 W).

  • Having a dry weight of 190 lbs, the Briggs & Stratton 30708 belongs in the expected weight range for generators which produce 5500 to 6500 rated watts. If weight matters to you, one of the champions in this power range is the Champion 201239 with only 111.6 pounds.
  • With around 11.5 hours of runtime at a 50% load on a full tank, the 30708 is in line with the average autonomy range for generators of comparable power. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 6500, reaching around 14.5 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. The generator utilizes approximately 0.65 GPH of gasoline at a 50% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP7000iH, with a fuel consumption of 0.38 GPH could be in your good books.

Price comparison

As you can see from these interactive charts, when compared to other 5500-6500W generators, the Briggs & Stratton 30708 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
