Description

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 sporting competitions, open-air performances and outdoor festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

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 5,750W and a peak wattage of 7,185W.

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

With a full tank, the 30708 can operate for around 11.5 hours at 50% load (fuel consumption around 0.65 GPH), thanks to its fuel capacity of 7.5 gallons.

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

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

At L29 x W21.5 x H25.5 in, the standard open frame design of the Briggs & Stratton 30708 delivers stability alongside easy maintenance access to components and good air cooling. The device has been designed for tough environments and demanding outdoor use.

With a weight of 190 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀10") and its folding handle, enabling easy shifting once the generator is set in place.

Features

The 30708's control panel

One of the many 30708's features is the digital data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.

With its built-in fuel gauge, the generator provides quick and convenient gas level checks.

As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing 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.

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 is a key factor for your needs, the Pulsar PGDA70BiSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 118 pounds.
  • The 30708's runtime of around 11.5 hours at a 50% load on a full tank positions it within the average autonomy range compared to other generators with similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 6500, which is able to run for around 14.5 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. When it comes to fuel efficiency among generators with similar wattage, this generator lags behind, with a consumption rate of 0.65 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA7000L, which has a fuel consumption of only 0.36 GPH and thus, is one of the most efficient devices in our database.

Price comparison

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

Therefore, this generator nicely fits in the expected budget for this kind of product.
