DeWalt’s new jobsite stereo comes in the shape of a ToughSystem storage container, and doubles as a battery charger, accepting 12- and 20-volt batteries as well as a USB port that charges a laptop or a smartphone. Music can be controlled by smartphone via a 100-foot Bluetooth connection. The six-speaker system is waterproof and dustproof. To lug it around, either attach it to another ToughSystem case or use the handle. It has an internal storage compartment and can be powered by battery or plugged into a wall.Price: $230 / COO: China /dewalt.com
