Key Features

Let us take a quick read at the special features that Generac GP3300 comes with to its consumers.


The most important aspect of a generator is undoubtedly its power because you definitely want your generator to smoothly run your connected devices without interruptions. The 3300 watts power of this machine is split between two circuits, each of which is 14 amps.

You can see the two legs of 120-volt sockets connecting to each of the 14-amp breakers. This enables two steady currents of more than 1600 watts.

Connect one of the circuits with your TV, computers, phones, etc. and the other one with your regular home appliances or the heater, furnace. This GP3300 model also comes with an RV adapter of 20 to 30 volts, so you can power different devices with different needs.


The runtime of a generator is a factor that you cannot avoid if you’re buying one. Since portable generators aren’t meant to be used for heavy load, they generally do not go a long time at a stretch. The Generac GP3300 has exactly the runtime you can expect from any portable generator.

It can run more than 10 hours at a time on 50% load. If you are planning to run an AC of 10,000 BTU, you may expect a six-hour-long runtime before you need to refill.


The GP3300 is absolutely safe to use as Generac emphasizes greatly on its customers’ convenience and safety. It is made sure that you won’t be hurting yourself while running the generator, even if there is a malfunction, or you are doing it the wrong way.

There are a few breakers equipped within the mainboard that will prevent burning or any such hazards in case of dysfunctions or over-use. The breaker will trip, and you can then apply maintenance and set the engine up again. There is also a shut-off system for when the oil lowers down.

With this system, if there is a leakage in the tank or you don’t perform maintenance or oil-change much, the engine will automatically shut down when the oil reaches low. You may think of it as a hassle and may not want to bother, but keep in mind that the supposed harm by any casualty would cost you a lot of bucks!

Also, you can just avoid the hazards by keeping the maintenance up reading the user-manual.
