Lightest 2.5kW inverter, 3-yr warranty · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 83
At $549, the Champion 201317 is the lightest 2,500-watt inverter in the group at 39.7 pounds, and Warranty leads at 100 thanks to Champion's 3-year coverage and lifetime tech support. Satisfaction reaches 90 and Reliability 88, with CO Shield auto shutoff and 53 dBA operation backing them up. Features sit at 70 because there is no propane option on this model, and Value at 84 reflects a price above the WEN and A-iPower. It is for campers and tailgaters who want a light, quiet, well-warranted inverter and do not need dual fuel.

Should you buy the Champion 2500W Ultralight?
The Champion 2500W Ultralight is for campers and tailgaters who want the lightest, best-warranted inverter that still runs a small cooler, lights and phone chargers. At 39.7 lb it is among the lightest 2,500 W inverters sold, with 1,850 running watts at under 3% THD, 53 dBA, and up to 11.5 hours per tank. It is $549, gas only, and carries Champion's 3-year warranty with lifetime tech support. If you need propane, the A-iPower SUA2301iD does that for $50 less.
Where it earns its score
- Warranty scores 100. Three years plus lifetime technical support, the best coverage in the category.
- Light enough for one hand. 39.7 lb, level with the WEN 56235i and 7 lb lighter than the Honda EU2200i.
- Quiet and long-running. 53 dBA and up to 11.5 hours per fill in eco mode.
- CO Shield and parallel ports. Carbon-monoxide shutoff, and a second unit doubles the output.
What to know first
- Features is the lowest factor at 70. No propane, no app, no remote start. It is a simple box that makes clean power.
- Gas only. The Champion 4000W Dual Fuel and A-iPower SUA2301iD both add propane.
- $106 more than the WEN 56235i. You are paying for the warranty, the CO sensor and the Champion name.
Our verdict
The Champion 2500W Ultralight scores 83, a Good Buy. It is the sensible 2 kW inverter for most campers. Pay $650 more for the Honda EU2200i only if resale and Honda's engine matter to you; save $106 with the WEN 56235i if you can live without a CO sensor.
