WEN DF450i Dual Fuel Inverter Generator vs Champion 4500W Dual Fuel Inverter 201321

The Champion 201321 is the better pick for most shoppers. It has more running watts on both fuels, a larger tank, longer run time and a CO shutoff that the WEN lacks. The WEN DF450i is noticeably quieter and lighter, and its fuel shut-off helps keep the carburetor clean. Owners of both report reliable starting and clean power for electronics; the Champion's open frame makes it louder but easier to service.

• Choose the WEN DF450i if quiet operation and lower weight matter more to you than maximum run time, and you want a fuel shut-off for easier carburetor maintenance.
• Choose the Champion 201321 if you want more running watts, a bigger tank, longer run time and a carbon monoxide auto shutoff for home backup and RV trips.
