The Oklahoma Sound Laptop Charging and Storage Cart offers ample space for keeping your classroom laptops safe and charged. The shelves have enough room for up to 24 laptops and chargers, and the locking doors open as wide as you need for easy access. Two built-in electrical assemblies on the rear panel allow you to charge half or all of your laptops at a time. The durable particleboard frame features a high-pressure, thermofused laminate that resists dents, scratches and peeling. Four swivel casters make movement between classrooms easy. Add one or two 24-hour timers for charging overnight or during off hours.
