Overview
A key start engine and a fuel selection dial run the WEN dual fuel generator, letting it burn gasoline or propane with a turn. A voltage selector moves output between household and dual voltage for a transfer switch.
Transfer switch readiness at a moderate size makes it a practical essentials backup without the bulk of the largest units. It is not an inverter, so clean power for electronics is not promised.
Who it's for
Suited to houses that need a few key circuits during outages and job sites needing dual voltage. Quiet campsite use calls for an inverter.
Pros and cons
- Gasoline or propane
- Key electric start
- Transfer switch twist lock
- Long half load runtime
- Not an inverter
- No USB outlets listed
- Heavy to lift
Performance notes
Output comes from a conventional alternator driven at steady engine speed, which suits motors and pumps. The voltage selector sets single or dual voltage depending on the job. Propane lowers output slightly but stores well for emergencies.
