Aleratec's Charge and Guard Secure Charge/Sync Cabinet 16 has been designed with specifically for tablet deployments where durability and security are critical. Our heavy-duty, all-metal construction protects up to 16 tablets while they are being charged or synced within the cabinet. A welded anchor loop allows you to chain the cabinet to a secure structure so that the cabinet itself can't be taken by unauthorized persons. Inside the cabinet are 16 USB ports that support smart-charging iOS, Android and most other mobile devices quickly with enough power for a full 2.4A per port. The flat top of the cabinet is an ideal place to set your laptop as you synchronize up to 16 devices simultaneously by connecting your computer to the cabinet's external USB port. The status panel on the front shows the charge or sync status of each attached tablet within the cabinet.
