Yamaha 4400W / 4500W Electric Start Gas Inverter Generator with CO Sensor

Power your life with the premium Yamaha 4400W / 4500W electric start gas inverter generator featuring an advanced carbon monoxide (CO) sensor. The EF4500iSE delivers 4500 peak watts and 4000 rated continuous watts – enough to run a 15,000 BTU RV air conditioner, a 1000W microwave oven, and several other appliances simultaneously.

Engineered for whisper‑quiet operation, this generator produces only 53 to 60 decibels, making it one of the quietest in its class. The exclusive Smart Throttle technology automatically adjusts engine speed to match the load, dramatically improving fuel efficiency and reducing noise. On a single 4.5‑gallon tank of regular unleaded gasoline, it runs up to 19 hours at 1/4 rated load – ideal for overnight camping or extended power outages in the USA and across Europe.

The pulse‑width modulation inverter system generates pure sine wave electricity that is cleaner than household grid power. You can safely operate computers, televisions, satellite systems, smartphones, and other sensitive electronics. The built‑in CO sensor shuts down the engine immediately if dangerous levels of carbon monoxide are detected, providing essential safety for home backup, RV use, or job sites.

This generator is brand new in box, ships from a trusted authorized Yamaha dealer with fast delivery within the USA (from Texas) and from local European warehouses. It comes with a 3‑year limited factory warranty. Outlet configuration includes two standard 120V 20A receptacles (5‑20R) and one 120V 30A twist‑lock receptacle (L5‑30R). Additional features: electric start with automatic choke, power meter, digital hour meter, fuel gauge, low oil warning shutdown, twin lifting bar, and four wheels with parking brake for easy transport and security. Meets all EPA and CARB emissions standards (USA) as well as strict EU regulations.
