The Paraproject Case C10 easily accommodates up to ten Chrome or Ultrabooks with screens up to 15.6 inches in compartments made of stable ConPearl plastic honeycomb. There is also plenty of space for the original power supplies, eliminating cable clutter and similar issues. The charging process for the devices can be conveniently controlled via a separate on/off switch. Ventilation openings in the lid and bottom ensure ideal temperatures. An optional external weekly timer is available, allowing for convenient charging scheduling over an extended period. The portable computers are protected during transport by the sturdy outer shell made of impact-resistant 3 mm thick X-ABS plastic, by the foam padding in the lid, and by the full-area foam lining on the bottom. The transport of the C10 case, secured with a combination lock, is made easy on four ball-bearing wheels, with a trolley function featuring a four-stage telescopic handle and carrying handles on both sides.
