Yamaha EF2800i Review – Gas Powered Portable Generator

If you were looking for the smallest inverter generator that offers over 20 amps of power, this Yamaha EF2800i Gas Powered Portable Generator does. You should not have any problem running the concession trailer with this generator and a commercial freezer. It can run for about 8 hours straight and uses about 3/4 tank of gas with the power save mode on.

Starts on the first pull every time. I’m thrilled with it. And for all the power it offers, it’s very lightweight. So let’s check out the Yamaha EF2800i review and facts that you should know.

Why Yamaha EF2800i is a good generator?

Yamaha EF2800i Gas Powered Portable Generator

Yamaha EF2800i offers comfortable, quiet operation in cabins, homes, and even RVs. The inverter system adds to its appeal with its clean, more reliable power and pulse width modulation control. A spark arrester is required in national parks, and Yamaha has one. Using the 25% generator allows you up to 15 hours of operating time, perfect for emergencies and weekend trips.

Inverter system with 2500 continuous watts:

An inverter system uses refined energy waves to generate electricity, which is ideal for more sensitive electronics such as computers and smartphones. The pulse width modulation (PW) control ensures no energy is lost during connection, making the generator more efficient. At its maximum, the generator can be rated at 2800 watts, with 2500 watts continuous.

2.9 gallons of gas and 15 hours:

At 2.9 liters of gas, the OHV engine can provide a whopping 15 hours of run time when using the 25% generator. When you use 100%, you get 7 hours, which many generators offer at half load. The overhead-valve design contributes to the generator’s overall fuel economy with increased durability and low fuel consumption.

Spark arrester:

A generator must have a spark arrester to camp in US national parks and forests. The Spark arrester prevents sparks from leaving the exhaust system and causing a fire. Yamaha has one, so you can use the generator for camping and other occasions.
