How to Choose the Right Small Gas Generator
When selecting a portable gas generator, consider the following factors:
1. Power Output
Ensure the generator can support the wattage of your devices. Always check both running and peak watts, especially if you plan to use equipment with startup surges like refrigerators or power tools.
2. Weight and Portability
If you’re constantly moving — whether camping, tailgating, or working remotely — opt for a lightweight model under 45 lbs. Larger models may offer more power but compromise ease of transport.
3. Noise Level
For outdoor and residential use, quieter generators (under 60 dB) are preferred. Inverter technology helps minimize noise significantly.
4. Fuel Efficiency and Type
All models here use gasoline, which is widely accessible. Look for models with long run times on a single tank if you’re planning extended use.
5. Inverter vs. Conventional
Inverter generators provide cleaner energy and are quieter and more fuel-efficient, making them better suited for electronics and variable loads.
