Description

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

Zoom on the Briggs & Stratton 30708

In summary, the Briggs & Stratton 30708 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Briggs & Stratton 30708's core is the 389 cc Briggs & Stratton OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 5750W and a peak wattage of 7185W.

Its starting mechanism is based on a conventional pull-start mechanism.

The fuel capacity of 7.5 gallons allows the 30708 to operate for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.65 GPH).

Outlets

The control panel provides the upcoming 7 AC outlets:

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

Since the 30708 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The dimensions of the Briggs & Stratton 30708, which are L29 x W21.5 x H25.5 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 190 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The 30708's control panel

To help you monitor the 30708's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Briggs & Stratton also included some oil in the 30708's packaging.

Emissions

The Briggs & Stratton 30708 is neither EPA approved nor CARB-compliant..

However, it features a spark arrestor and thus, may be used in forested areas.

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).

  • Since the generator weighs in at a dry weight of 190 lbs, the Briggs & Stratton 30708 belongs in the expected weight range for devices which can produce between 5500 and 6500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar G65BN, with a dry weight of just 126 pounds.
  • The 30708, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 11.5 hours at a 50% load and a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides around 15 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.65 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA7000L, with a fuel consumption of 0.36 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, 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.
