Generac 5939 GP5500 Features:

Powerful Engine: Generac 389cc OHV is a solid engine capable of delivering consistent power. Splash lubrication makes it a long lasting engine which is a great plus. This unit can be used outdoors for camping trips or as a backup source.

Frame: The generator is enclosed in a durable frame made up of 1 ¼ hard steel tube cradle. It makes the unit durable and also safer to use.

Large Fuel Tank: The generator is equipped with a 7.5-gallon fuel tank that continues to deliver continuous power. There’s also a fuel gauge installed on the tank that allows you to check fuel level.

This makes it easier as you will never run out of oil since you’ll know when it’s time for a refill.

Low Oil Alert: The low-oil shutdown feature turns the engine off when there is little to no oil in the unit. This is of huge importance as a low level of oil can harm the engine and cause the unit to malfunction. This, however, is not a trouble with Generac 5939 GP5500.

Hour Meter: You can track maintenance intervals using the hour meter that comes equipped on the generator. This makes management easier and reduces the burden.

Runtime: This portable generator can run for up to 10 hours on a full tank at 50% load. Decreasing the load will increase the runtime by a few more hours.

Circuit Breaker: It’s a safety feature that protects outlets from getting damaged due to current overload. Thanks to it, the unit will automatically trip if it feels burdened.

This does not only keep the generator safe but also prevents appliances from sustaining damage.

Easier To Move: Do not let its weight of 180 pounds scare you, the generator comes with large tires underneath the body that make it easier to move the unit from one place to another. Its never-flat wheels are very durable and can bear the weight of the unit without any trouble.

Starting: This unit has a manual recoil start system that some users may not like. It can, in fact, take two tries to turn on the engine.

Outlets: The unit incorporates four 5-20R 120V outlets and one L14-30R Twist-Lock 120/240V outlet. Thanks to them, you can power up to 5 different appliances simultaneously.

Handle Style:  It comes with a fold and lock handle. It’s cleverly designed and puts no strain on the body.

Warranty: The unit comes with 2 years of warranty for residential users. Commercial users get 1-year of warranty or 1,000 hours, whatever comes first. However, customer service is not very good and service centers can be difficult to find.

You can use this link to locate a dealer.

Quiet Operation: There’s a low tone muffler device attached to the unit that suppresses the noise produced by the generator when it’s operational. Thanks to it, picnics, trips, and camping expeditions become fun and relaxing.

The unit won’t disturb your sleep if you keep it a few feet away from your room.
