Since the machine comes with a low-tone muffler, it does not make a lot of noise when it is switched on. The integrated fuel gauge in the generator will inform you when you need refueling. The generator comes with an ergonomic fold-down handle, which is sturdy and lockable. It is easy to store because of the compact design. The heavy-duty wheels make it easy to transport the generator from one place to another.

The smooth lubrication ensures that the engine does not suffer from excessive wear and tear. Additional features like the auto shut-off make sure that you do not unintentionally damage the machine.

Fuel tank capacity and run time

The fuel tank capacity should be a major concern when you are examining a portable generator. If you are looking for a portable generator that will run for a significant amount of time, then this model fits the bill. It operates on gasoline and is easy to operate. The fuel tank capacity of 7.5 gallons is enough to accommodate fuel to power all your important appliances. This generator will run for 9.5 hours at 1/2 load. You can use it overnight as long as you only use it to power basic lights and fans. It also provides excellent coverage, which means that it can supply electricity to your entire house.

Control panel and outlets

The control panel on the model is easy to navigate, and you will get adjusted to the different settings soon. It comes with covered outlets that are safe. You will appreciate the hour meter that will give you reminders for maintenance. The electric start is very convenient when you want to use the generator in a hurry.

The low-oil level shutdown will save you the hassle of tracking the fuel in the generator. You will be notified when you have to refill or when the generator needs maintenance.

Safety features
