2 kW inverter generator


The EF2000iS Inverter Generator: powerful, portable and super sleek with lots of great features. This overall best seller is great for recreational activities such as camping, fishing and boating.  It's also a great companion for the camper-trailer. However, if you have something larger like a caravan, the Yamaha EF2400iS is the recommended mode for when travelling in hot weather conditions.

The EF2000iS has enough power to run a microwave oven, a camping fridge, small air conditioner, kettle or television.  It is fitted with a newly designed muffler and air filter to achieve super quiet performance and because of its advanced Noise Block sound reduction system you can have a conversation without having to raise your voice. 

Also available with TwinTech Parallel Use function - for almost double the power when connecting two EF2000iS together!
