Tripp Lite 36-Device AC Charging Station Cart for Chromebooks and Laptops,

The CSC36AC 36-Device AC Charging Station Cart provides timed AC charging, secure storage and cord management for 36 Chromebooks and laptops with a screen size up to 15 inches.
The connected devices’ AC adapters plug into the cart’s 36 NEMA 5-15R outlets as needed. 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.
An RJ45 jack allows you to connect external Ethernet equipment, such as wireless hotspots, inside the cabinet. The laminated wood-grain top acts as a writing surface and 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.
Constructed from heavy-duty steel covered with a black powder-coated finish, the CSC36AC provides safe, secure storage. The front and back doors lock to help prevent theft, damage and tampering, and flow-through ventilation helps prevent devices from overheating.
To prevent cable clutter, device power adapters stow away in removable baskets. Charging cables run through zoned slots and into an overhead cable manager.
Moving devices from room to room is easy. Large swivel casters with non-marking wheels improve the ride over uneven surfaces and lock to help prevent unwanted movement. The reversible wide-grip handle makes the cart easy to control. Corner safety bumpers protect walls and doorways from scratches.
