It's not uncommon to have generators weighing over 120 lbs. And weight usually corresponds to power output. That is, until Yamaha created the EF2800i. Tipping the scales at just 64 lbs., it's the lightest generator in its class. The key is its multipole rotor with a small stator and Pulse Width Modulation inverter. This design is smaller and lighter than a conventional two-pole alternator and large stator — and it makes the EF2800i extremely portable.
