The QwikLink Tablet Charging Cart from Datum lets you store, transport and charge your classroom tablets. A special USB attachment on this cart allows you to hook up a computer and sync the software on all tablets simultaneously. The heavy-gauge steel frame features sliding tambour doors with a locking hasp and translucent PVC fronts that let you keep an eye on your devices. Two swivel casters and two fixed casters allow for easy movement between classrooms, and the laminate wood top offers room for projectors and other materials. A three-point locking rear panel gives access to the timer and electrical cords. The sides of the cart and the inner dividers have ventilation panels to prevent overheating. Rubber corner bumpers protect your walls, doorways and furniture. An optional two-outlet pop up electrical outlet lets you power a projector on top of your cart.
