#1 Yamaha EF2000iS 4 Stroke Generator
The EF2000iS is a portable inverter that is powered by 1600-watt 13.3/16.7 amps at 120 volts with an AC maximum output of 2000 watts. Unlike most commercial generators it produces sine waves which has been acknowledged as a cleaner source of power. When you start the machine with the touch of a button it fires to life instantly due to its auto-decompression system. A safety feature is the electrical overload breaker which protects the motor from any damage that might be created by an overload. The EF2000iS is one of the most efficient generators and is able to provide 10.5 hours without replenishing fuel in an economy mode.
The weight of the generator is only 44 pounds which makes it very light and portable. A control panel contains all the controls that you might need to monitor the performance of the generator. An additional feature is the recharging system that uses its 8A12V DC output which means that it can be recharged easily on a boat or RV. If the generator has less oil it will not be a cause for worry as the system shuts of automatically when the oil level is too low and may have the potential to cause any damage.
The EF2000iS is extremely quiet with noise-absorbent wool and special sound blocking features like a super quiet muffler and vibration isolators in its feet.
