 A detailed review of Yamaha EF1000iS inverter generator

A compact Yamaha EF1000iS delivers a maximum output power of 900W for running emergency devices. So, it is an excellent choice for homeowners as well as for contractors and car dwellers. Although this generator is not for running whole-house appliances, it helps in keeping the essential devices active to manage unexpected power cuts. 

It is extremely lightweight compared to other inverter generators in the market. Many customer reviews say that you will hardly notice the generator while carrying. With 27.9 pounds, you can put this on the backside of the car and start your trip. 

When it comes to performance, delivering output power from a compact generator is highly incredible. An impressive runtime of 12 hours at rated quarter load is enough to keep the essential devices like lights, fans, and heavy ampere appliances like refrigerators active during power cuts occurring at late nights. So, you don't have to wake up in the middle of the sleep to reduce the connected loads or refill the tank. On the whole, this generator is worth buying for its impressive features. 

Tank capacity and runtime

The compact tank holds up to 0.66gallons to provide a runtime of about 12 hours at an applied 25% load. Since this runtime exceeds your sleeping time, you will not find any disturbance during the whole night due to a power shortage.  Smart features like the eco-throttle mechanism will control the engine speed based on the laid connected to the unit. So, you can conserve fuel and extend the runtime. 

Performance and outlets 

Since the name is Yamaha, it is not a surprise to observe a stellar performance in the generator. This generator comes with an inbuilt 50cc powerful engine that delivers a running watt of 900W and a starting watt of 1000W. This average output is enough to run the emergency devices like mobile phones and tablets. 

Above all, the inverter technology in this generator will produce clean power without any voltage spikes. So, it is extremely safe to run sensitive electronic devices. This generator comes with power outlets like a 12V DC outlet and a 12V duplex for battery charging. 

Easy to use
