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
  • Homeowners in need of an emergency backup power for their essentials
  • 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 houses a 389 cc Briggs & Stratton OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5750W along with a peak wattage of 7185W.

This generator gets running thanks to a conventional pull-start mechanism.

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 includes the following 7 AC outlets:

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

As the 30708 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during 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. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 190 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Never less, thanks to a wheel kit (⌀10") and a 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.

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

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Besides the usual set of documentation and user manual 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).

  • With a dry weight of 190 pounds, the Briggs & Stratton 30708 finds itself in the expected weight range for generators able to produce between 5500 and 6500 rated watts. If weight matters to you, one of the champions in this power range is the Lifan LF7250 with only 140 pounds.
  • The 30708, offering a run time of around 11.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Cat RP5500, with around 15 hours .
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.65 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

Price comparison

As you can see from this dynamic 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.

The bottom line

STRENGTHS:
  • Inexpensive
AVERAGE SPECS:
  • Decent weight (190 lbs)
  • Decent run time
WEAKNESSES:
  • No electric start
  • No EPA or CARB compliance
