The Oklahoma Sound Tablet Charging and Storage Cart offers plenty of space to keep your classroom tablets or netbooks safe and charged. Open the locking doors as wide as you need for easy access to your devices. Two built-in electrical assemblies on the rear panel allow you to charge half or all of your devices 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.
