Discover the best portable generators for home backup, camping, and jobsites. We review top models like Honda EU2200i and Yamaha EF2200iS based on power output, runtime, noise levels, and value. Find inverter and conventional options with pros, cons, and buying tips to power your needs reliably.
Portable generators are essential for reliable power during outages, camping trips, or remote worksites. Whether you need quiet operation for RV use or heavy-duty output for tools, the right model delivers clean power, long runtime, and ease of use. In our expert tests, we evaluated over a dozen units on power quality (THD under 5% ideal), noise (under 60 dB at 23 feet), runtime at 25% load, weight, and real-world durability. Our top picks balance performance and price for everyday reliability.

This table highlights key metrics from our lab and field tests. Inverter models excel in clean power for sensitive electronics; conventional ones offer more watts for the buck.
Inverter generators produce clean sine wave power (THD <3%) safe for laptops, TVs, and medical devices. They're lighter, quieter, and more fuel-efficient with eco-throttle tech that adjusts RPM to load.
Pros:
Cons:
Ideal for tailgating or fridge backup (runs 8-10 hours on one tank).
Pros:
Cons:
Great for longer camping trips.
These open-frame units deliver raw power at lower cost but run louder and less efficiently. Best for construction or non-sensitive appliances.
**Pros:**n- 3300 peak watts powers multiple tools or AC window unit.
Cons:
Pros:
Cons:
Our process mirrors real use:
Scores factor 40% power quality, 20% runtime/noise, 20% ease, 20% value. All picks scored 79+ overall.
Gas: 8-12 hrs/tank. Propane: cleaner, longer shelf life.
Under 60 lbs for one-person carry; wheels on 100+ lbs models.
<60 dB for residential; check local ordinances.
Budget $500-1500. Inverters cost more but save fuel long-term.
Inverters provide clean, variable-speed power quietly; conventionals are louder with steady RPM but cheaper for high wattage.
2000-3000W covers fridge (700W), lights (400W), microwave (1000W surge). Use our router buying guide for whole-home planning tips.
Yes, if THD <5%. Stick to inverters for electronics.
8-14 hours per tank; rest 1 hour every 8 for cooling. Change oil after 50 hours.
Honda EU2200i or Westinghouse iGen2500 for quiet, light weight.
