Generac GP3300i Power and run time

 The Generac GP3300i’s 149cc Generac OHV 4-stroke petrol engine can supply 120V. It delivers an operating power of 2500 W and reaches a maximum power of 3300 W. In addition, the device is parallel compatible (parallel kit (opens in a new tab) not included) and can therefore be paired with a similar or compatible device for a higher power.

The starting mechanism is based on a simple traditional pull-start mechanism. Features Generac’s PowerDial™, an easy-to-use dial with three control settings.

The capacity of 1.06 gallons allows the GP3300i to run for up to 7 hours on a full tank (fuel consumption of about 0.15 GPH).

The GP3300i generates a pure sine wave: sensitive electronic devices can safely connect to their sockets with <3% Total Harmonic Disruption (THD).

Generac GP3300i Outlets

The control panel has the following 3 sockets:

  • Double-Sided 120V 20A (5-20R)
  • 120V 30A Power Strip (L5-30R)

It also has 2 DC outputs: two 5V USB ports, which makes it convenient to charge electronic devices such as mobile phones and tablets.

Although this Generac generator is not RV-ready, the L5-30R connection can be used for a simple RV connection with an L5-30P to TT-30R adapter.

Portability of Generac GP3300i

Because the Generac GP3300i is an inverter generator, the encapsulated design (L22.2 x W13.3 x H18.4 inches) offers more aesthetics than a conventional open-frame product. This design is the most modern and convenient way to generate power recreationally.

With a dry weight of 59.5 lbs, the GP3300i can easily follow you wherever you need power. Moreover, changing is a breeze, as the GP3300i has a handy handle (moulded into the housing), which greatly improves the grip.

Generac GP3300i Other Features

The indicator lights on the unit indicate if the generator is ready, the oil level is too low, and the generator is overloaded.

For safety, the generator is equipped with overload protection (circuit breaker) and automatic low oil shutdown, giving you peace of mind during operation.

In addition to classic documentation and a user manual (opens in a new tab) to get you started quickly, the Generac GP3300i also comes with a few accessories: a tool kit, funnel, and oil included.

The Generac GP3300i is covered by a warranty of up to 3 years. This warranty may be limited and may not cover all generator parts.
