The new and upgraded Bosch Power Box™ is an advanced jobsite stereo with a CD player, an MP3 player port, AM/FM radio, and a remote control. The aluminum and rubber roll cage protects the radio unlike any other, withstanding even a ten foot drop. The latest features include an advanced antenna and digital tuner for improved radio reception, a new subwoofer, and four-way speakers that blast high-quality sound in 360 degrees. The small carabineer remote control attaches to a keychain and stores on the Power Box handle. In addition to playing CDs, MP3s, and iPods (from a protective interior charging station), the Power Box also recharges Bosch power tool batteries, cell phones, and other 12v electrical equipment. The backlit UI was redesigned to be more user-friendly, and rubberized chambers seal the buttons and speakers to protect the internals from dust and weather conditions.
