How we compared

Each model's figure is the median of its counted independent tests: US units at 120 V, AC output, loads of 100 W or more. A brand's average is the plain average of its models' figures, so a brand with a few very large or very small models isn't weighted toward them. Prices are from each brand's US store, unit only, on the date shown on each review; we don't show Amazon prices. Our score leaves price out. How we test and score · Every model's real capacity
