THE ALL NEW EF2200iS with CO Sensor!

Genuine Factory New Yamaha Generators

The Yamaha EF2200iS Watt Generator is a completely new Inverter Generator from Yamaha. It weighs in at 55.2 pounds, making it easily portable. Among the quietest portable generators in its class, the EF2200iS features Yamaha Quiet Technology which allows quiet operation like no other generator in its class.

Designed for emergency home backup portable power use, RV and camping power needs, and as a power source on many DIY home projects, the EF2200iS is the first in Yamaha’s upcoming lineup of generators exclusively equipped with CO Sensor technology to meet the Portable Generator Manufacturers’ Association’s™ (PGMA®) ANSI/PGMA G300-2018 standard to monitor carbon monoxide emissions. When the CO Sensor detects elevated levels of carbon monoxide, the EF2200iS automatically shuts off and will remain off for approximately five minutes, with indication that the generator needs to be moved to a well-ventilated space. A new CO Sensor graphic and LED indicator lights on the control panel notify the user of carbon monoxide emission levels or system malfunctions.

4 of 5 Good price and service.. EXCEPT July 1, 2022
Reviewer: Pete from Columbus, IN United States  
No problems or issues with Natl Supply but FED Ex was supposed to deliver with "signature required" - as is clearly noted on the Natl Supply site.
They dropped the unit off on my front porch and didn't get a signature even though we were home - WAITING for the shipment after 3 reschedules.    So, we stayed home for 3 different days when they said they were going to deliver, more than a bit of an inconvenience.  Your experience in your town with Fed Ex may be different but I'd love to get 3 days back.

5 of 5 Great generator June 19, 2022
Reviewer: Brian Clark from Nampa, ID United States  
Received generator quickly. Shipment only took a couple of days. Love the 30 amp receptacle so I can plug my trailer in and it easily handles the AC unit load. No issues. Definitely going to come in handy boondocking in the woods. Fairly quiet.
