The Yamaha EF2000iS portable inverter generator is capable of generating up to 2,000 watts of power (1600 watts rated) for use in the home or at the jobsite. The OHV (overhead valve) engine is capable of running up to 10.5 hours without having to refuel when economy mode. Featuring Smart Throttle Load the unit is able to dynamically adjust engine speed depending on output, leading to greater fuel efficiency. The unit is also fitted with super-quiet muffler technology and vibration isolating foot stands keeping emitted noise whilst running to a minimum. The EF2000iS is also able to recharge batteries with its 8A12V DC output; making it the ideal generator for RV, auto, and boat owners. The ergonomic, compact and yet sturdy design ensures that the unit is easy to carry for maximum mobility.

Users have been impressed by the quietness of the unit whilst running, stating that the Yamaha EF2000iS generator is significantly quieter than other similar competitor models on the market today. This bonus makes the unit perfect for use at home as a backup power supply during emergency blackouts and extreme weather conditions as well as for supporting various power tools simultaneously. The compact and solid frame of the unit ensures that it can be stored discreetly in a garage or shed to be transported for other applications. Since the unit is an inverter, the unit is also capable of supplying AC power to computers and other electrical appliances making the generator ideal for domestic use around the home.
Users have commented that checking the oil level is inconvenient as there is no gauge on the external power panel or dipstick. This could be improved by fitting a low oil indicator. However users have recommended that potential customers should purchase a quart of standard 4-stroke engine oil and invest in a funnel in order to avoid spillages when using the oil filler hole. Although some have commented that even with a funnel, the oil filler hole is located in a difficult place and as it is near horizontal even with a funnel the act of re-filling the oil may be slightly messy.

Overall, customers are extremely satisfied with the general consistent performance and dependability of the Yamaha EF2000iS making for a very favourable review. This coupled with the value for money, minimal noise emission and uniquely compact and ergonomic frame ensure that the unit is praised very positively.

Have your say.
