The Paraproject Case C10 easily accommodates up to ten Chrome or Ultrabooks up to 15.6 inches in form-stable ConPearl plastic honeycomb compartments. There is also plenty of space for the original power supplies, eliminating the hassle of tangled cables. The charging process for the devices can be conveniently controlled via a separate on/off switch. Ventilation openings in the lid and bottom ensure optimal temperatures. An optional external weekly timer is available, allowing for convenient charging planning 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 foam fully laid out on the bottom. The transport of the Case C10, secured with a combination lock, is made easy on four ball-bearing wheels, using the trolley function with a 4-stage telescopic handle, and with carrying handles on both sides.
