The Laptop/Netbook Charging and Storage Cart from Buhl Industries features a welded steel frame with a durable powder-coat finish. Wire slot dividers adjust in half-inch increments, so you can fit laptops and netbooks or varying sizes. A built-in cooling fan and perforated side panels ensure your computers don't overheat. Locking doors keep your equipment safe, and four swivel casters make it easy to move the cart between rooms. A self-contained charging system offers timed alternating charges, and the power cord plugs into standard wall outlets. Choose a cart with 16 or 24 laptop bays.
