Charging station cart provides timed AC charging, secure storage and cord management for 36 Chromebooks, laptops and tablets with a screen size up to 15". To conserve energy and avoid potential overloads, the outlets are evenly split into two charging zones. Each zone charges for one hour at a time until a built-in timer switches to the other. RJ45 jack allows you to connect external Ethernet equipment, such as wireless hotspots, inside the cabinet. Laminated woodgrain top holds a projector and other devices that plug into two external NEMA 5-15R outlets. An inside switch can turn these outlets off to protect against overloads. Lockable front and back doors help prevent theft, damage and tampering. To prevent cable clutter, device power adapters stow away in removable baskets, and charging cables run through zoned slots and into an overhead cable manager. Large swivel casters with nonmarking wheels improve the ride over uneven surfaces and lock to help prevent unwanted movement.
