Pros
- Refills from a 20 lb propane tank, which stores far longer than gasoline
- Remote key fob and push-button start, so no pull cord
- TT-30R outlet plugs a travel trailer straight in
- Shuts itself off if carbon monoxide builds up nearby
- Wheels and a telescoping handle for a 63 lb unit
Cons
- Small 1.7 gal tank means refueling during an overnight outage
- Not CARB compliant, so it cannot be sold in California
