 Tip:  Know your generator limits.

  • Add the total wattage of ALL electrical devices to be connected at the same time.
  • The total running watts should NOT be greater than the generator’s wattage capacity, i.e. 2200 watts for this Generac.


TruePower™ Technology is the highlight of this generator.

This feature produces clean power required by sensitive electronic devices such as laptops and cell phones.

Alert System. Generac GP2500i Inverter is equipped with an LED display system that alerts the user if the generator is low on oil, overloaded, or ready to use. Another plus point is that this product also can automatically discover low-oil level. It will shutdown to protect the machine when a malfunction is detected.

Noise level. Generac GP2500i Inverter is considered a fairly quiet generator. The noise it produces is approximately 60dB at lower loads, partly thanks to the sealed body design that reduces motor noise.

This noise level is acceptable at tailgating or camping.

Alternatively, if you are still concerned about this noise, you can use the “Economy mode” feature. Though this function will lessen the power to run the connected devices, the noise level will also be significantly reduced.

The GP2500i also offers a unique feature that few product lines have, a paralleling capability.

You can connect it to a device of the same type using a parallel set (sold separately).

You will receive twice as much electrical power (for larger appliances).
