Space-Saving Charging Stations Accommodate up to 40 Chromebooks and Tablets
The CST40AC consists of two CST20AC 20-device charging towers. These wall-anchored, floor-standing 120V charging stations provide high-speed AC charging, secure storage and cord management for as many as 40 Chromebooks, tablets and other mobile devices with a screen size up to 16 inches. These towers are recommended for schools, small/medium businesses, medical facilities, government agencies and anywhere else that uses Chromebooks or tablets on a daily basis.
Space-Saving Form Factor Ideal for Mounting in Busy Classrooms
Designed to fit into classrooms and other areas with limited floor space, the two CST20AC units each feature a space-saving footprint of less than two square feet, perfect for small or crowded rooms. They attach to the wall with the included mounting brackets. They anchor to the wall at floor level, which allows access to younger children who need to charge their devices at school.
Open Frame Design Allows Convenient Visibility without Unlocking the Door
An innovative open frame design allows you to see devices without unlocking and opening the half door in front. When checking at the end of the day to see whether all the Chromebooks or tablets have been returned, you can just glance at the charging stations from across the room for quick confirmation. The open sides allow cool air to easily flow through each tower, enhancing the performance of your devices and extending their life.
High-Speed Charging with Plenty of Power to Keep Every Device at Full Capacity
Both charging towers come with a 20-outlet PDU already installed, giving you a dedicated NEMA 5-15R receptacle for every power adapter. Each tower has a charging capacity of 1440 watts, enough to charge all Chromebooks.
Locking Steel Enclosure Keeps Valuable Equipment Safe and Secure
Constructed from heavy-duty steel covered with a white powder-coated finish, this charging tower provides safe, secure storage. Devices and their power adapters are stored in separate compartments. The front door and top panel both lock with included keys to help prevent theft, damage and tampering. Strategically placed bars down the sides prevent anyone from sliding a Chromebook out of the locked tower. The top panel allows access to the upper outlets and power adapters. A 15-amp circuit breaker protects the devices against overloads. 
Well-Organized to Avoid Confusing Cable Clutter
The CST40AC is compatible with a wide array of mobile devices, including Chromebooks, iPads, Android tablets, Surface tablets, Kindle e-readers and other mobile devices with screen sizes up to 16 inches. Power cords are routed through cable management slots to keep them organized and prevent tangles. Each shelf comes with a numbered sticker for easy identification and is specially coated to help prevent device scratches and scuffs. The towers' 10-ft.(3.05 m) cords with NEMA 5-15P plugs allow great flexibility in placing the units near an AC wall outlet.
Secure the Towers to a Wall or Move Your Devices from Room to Room
Mount the charging stations on a wall with the included brackets and user-supplied hardware. If you prefer the flexibility to roll the towers from one room to another, an optional caster kit (CSTCASTERKIT20, sold separately) includes four casters, mounting platform, handles and a locking rear door.
