This boombox can really take abuse! A steel-and-rubber frame protects the ruggedized shell, which houses four GFCI protected outlets for power tools. The outlets cut power if water leaks in, so you won't get fried. There's also a slot in the back to charge the batteries for your cordless power tools; when you find yourself away from an outlet, the radio can run off those same batteries. The radio also includes a mini-plug input for your MP3 player and a 12V DC outlet.
