WEN DF451i Dual Fuel Inverter Generator vs Champion 4500W Dual Fuel Inverter 201321

The Champion 201321 is the better pick for most shoppers. It runs far longer on a tank, has a larger engine, and adds a CO shutoff that the WEN lacks. The WEN DF451i is quieter at 58 dBA versus 64 dBA, and its Auto Fuel Selection and fuel shut-off are handy for RV and camping use. Owners of both report solid reliability for occasional backup and tailgating; the Champion's open frame is heavier and louder, while the WEN's smaller tank means more refueling.

  • Choose the WEN DF451i if quiet operation matters most, you want the lowest noise for campgrounds or tailgates, and you value Auto Fuel Selection and a fuel shut-off for easier maintenance.
  • Choose the Champion 201321 if you want long run times, a bigger engine, and a carbon monoxide auto shutoff for home backup and RV trips.

What reviewers say

WEN DF451i Dual Fuel Inverter Generator

Owners of the WEN DF451i generally report it starts easily, runs quietly for its size and handles RV and campsite loads well. Complaints center on weight, propane output loss and the small fuel tank.

What people mention
  • NoisePraisedOwners say it is quiet enough to talk over at a campsite, close to the claimed 58 dBA at light load.
  • StartingPraisedThe keyless electric start is reported to fire up reliably, with the recoil starter as a backup.
  • WeightCriticisedOwners find it heavy to lift in and out of a truck or RV compartment despite the wheels.
  • Propane outputMixedRunning on propane avoids fuel gumming but costs about 350 rated watts compared with gasoline.

Questions and answers

Which is better for RV camping?
The WEN is the quieter choice and has a dedicated TT-30R RV outlet, which suits campgrounds with noise rules. The Champion runs much longer between refuels, which helps on longer trips without hookups.
Which lasts longer on a tank?
The Champion. Its 4.02-gallon tank gives up to 22 hours at 25% load on gasoline, and a 20-pound propane tank gives about 21 hours. The WEN runs about 8.5 hours on gasoline at half load and 9 hours on propane.
Is the Champion worth stepping up to?
Yes for home backup and long trips. You get more rated watts, much longer run times, and a CO Shield shutoff. Pick the WEN instead if low noise is your top priority.
Which is quieter?
The WEN at 58 dBA at quarter load versus 64 dB(A) for the Champion. The gap is noticeable at a campsite or tailgate.
Does either have carbon monoxide protection?
Only the Champion. Its CO Shield system automatically shuts the generator down when carbon monoxide builds up. The WEN has no CO shutoff.
Can both run on propane?
Yes. Both are dual fuel and run on a standard 20-pound propane tank. The Champion includes a 6-foot propane hose with a built-in regulator; check the WEN box for the hose.
