Yamaha’s EF2000iS weighs a mere 44 pounds yet puts out 16 amps to power most household appliances, and you won’t believe how quiet it is. If you need more power connect two EF200iS together and almost double the power to run major appliances. Yamaha factory warranty covers parts and labor for 3 years. MSRP is $1099.00.
