Description

Keep your lights on, your food cold, your family connected – and more – during a power outage. (source: Briggs & Stratton (opens in a new tab))

Zoom on the Briggs & Stratton 30708

In a nutshell, the Briggs & Stratton 30708 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 design includes a gasoline-fueled 389 cc Briggs & Stratton OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5750W and also a peak wattage of 7185W.

Its starting mechanism is based on a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 7.5 gallons, the 30708 can 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

As it features a twist-lock L14-30R receptacle, the 30708 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The Briggs & Stratton 30708 has the following dimensions: L29 x W21.5 x H25.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

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, 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

Monitoring of the 30708's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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 therefore, can 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).

  • At a weight of 190 pounds, the Briggs & Stratton 30708 places in the expected weight range of the generators in the 5500-6500 rated wattage range. If weight matters to you, one of the champions in this power range is the Lifan LF7250 with only 140 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Cat RP5500, which is able to run for around 15 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. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.65 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Lifan ESI 7000iER-EFI, which has a fuel consumption of only 0.38 GPH and thus, is one of the most efficient devices in our database.

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.
