The trolley makes it possible to charge 20 tablets or ultrabooks at once, so you remain flexible at all times and don't have to worry about there being no sockets. An adjustable divider allows for the device module to be adapted to notebooks measuring up to 21 x 254 x 380 mm (16 inches) in size. The devices are placed between ABS panels and each given their own place. All power is supplied completely on a removable mounting plate which has its own internal power distribution, is mutually compatible with the GST18 connector, and features a C14 power entry module with an integrated switch and automatically resettable fuse. To protect the devices from overheating, the trolley features a powerful yet quiet fan. Maximum protection is provided by the rugged aluminum and con-pearl construction with built-in lock, the sliding handle, and four high-quality castors for convenient transport. Small items such as power cords can be stored in the pocket on the lid. The charging case comes equipped with country-specific connector strips (internal power distribution, mutually compatible with GST18).
