What to look for in a portable generator

- Noise: for camping or RVs, choose a quiet inverter like the Honda EU2200i.
- Runtime: check hours per tank at half load, and whether it has an electric start.
- Warranty: 2 to 3 years is common; buy from the brand or authorized seller for coverage.
How much should you spend on a portable generator?
- $300 to $600: value gas units (Westinghouse WGen3600v) for basic backup.
