Amazon customer rating: 4.5 / 5 - WC Safety review of the WEN 4500-Watt Inverter Generator, RV-Ready, Quiet, Portable and Lightweight with Fuel.
Written by Steven Eaton, WC Safety Editorial, from the published WEN listing. The score above is the live Amazon customer rating captured at review time - not a WC Safety test result. We did not laboratory-test this product.

The WEN 4500-Watt Inverter Generator, RV-Ready, Quiet, Portable and Lightweight with Fuel is one of our picks for the CO-shutoff generator lineup. Everything below comes straight from the manufacturer's published listing - specs, capacities, and dimensions are theirs, not ours.

Every generator in this collection has one non-negotiable feature: a built-in carbon monoxide sensor that shuts the engine down when CO accumulates - the technology (CO Sensor, CO Shield, CO Watchdog and similar, named per listing) that the CPSC credits with preventing generator CO deaths. It does not make indoor use safe: generators run outdoors, 20+ feet from openings, exhaust pointed away, with working CO alarms in the building. See how to run a generator safely.

Key details, quoted from the manufacturer's published listing:

  • 181cc engine generates up to 4500 surge watts and 3600 rated watts
  • Produces clean power to prevent damage to sensitive electronics such as smartphones, tablets and laptops
  • The WEN Watchdog CO Shutdown Sensor helps protect both you and your family by automatically turning off the generator if dangerous levels of carbon monoxide are detected
  • Fuel shutoff maximizes the generator’s lifespan by using up the remaining fuel in the carburetor before shutting down
  • Includes two three-prong 120V receptacles, one TT-30R RV receptacle, one 12V DC receptacle, an intelligent data meter, two 5V USB ports, and a three-year warranty

Compare all CO-shutoff generators, run power through rated heavy-gauge cords, and browse all jobsite equipment.

What to check before you buy

Carbon monoxide is the headline hazard
A portable generator produces CO in quantities that can be fatal indoors within minutes. It runs outdoors only, well away from doors, windows and vents - never in a garage, basement or crawlspace, even with the door open.
Running versus starting watts
Starting (surge) watts cover the momentary draw of motors; running watts cover continuous load. Sizing to the running figure alone leaves you short the moment a compressor or pump kicks in.
Transfer switch for any building connection
Connecting a generator to building wiring without a properly installed transfer switch can backfeed the utility line and endanger line workers. That connection is electrician territory.
GFCI and cord condition
Wet or outdoor use needs GFCI protection and outdoor-rated cords sized for the load and the run length.

Frequently asked questions

How far from the house should a generator be placed?

Guidance from the CPSC is to run it outdoors and at least 20 feet from the building, with the exhaust directed away from doors, windows and vents. Distance alone does not help if exhaust can drift back inside.

Can I run a generator in the garage with the door open?

No. An open door does not clear CO from an attached structure, and this scenario appears repeatedly in fatal poisoning investigations. Outdoors and away from the building is the only safe placement.

What size generator do I need?

Add the running watts of everything that will run at once, then add the single largest starting surge on top. Motor-driven equipment such as compressors, pumps and refrigeration drives the surge figure.

Do I need a CO alarm if I own a generator?

A working CO alarm inside the building is a sensible backstop, and newer portable generators may include a CO shutoff feature. Neither replaces correct outdoor placement.

Can I plug a generator into a wall outlet?

No. Backfeeding through an outlet energizes the utility line and can kill line workers, as well as bypassing overcurrent protection. Use a transfer switch installed by a qualified electrician.
