The Worx Aerocart may look like just a 3-cubic-foot-capacity wheelbarrow, but it has hidden capabilities. A metal plate folds down to transform it into a handcart. Accessories increase its utility: A cylinder holder assists with carrying water bottles and propane tanks; a strap secures objects to the cart; and extension arms (similar to forklift tines) extend the footprint of the dolly, making it easy to move appliances or heavy bagged goods. The Worx is rated for a 300-pound load, and its two-wheel design adds stability, particularly when it’s used as a wheelbarrow. At 22 inches wide, it can fit through almost any door. The powder-coated frame won’t rust, according to the manufacturer. Price: $160 / COO: China / worx.com
