Classroom Basics Tablet / Chromebook Charging Carts safely charge, store and transport tablets and Chromebooks to meet the evolving IT needs of classrooms and dynamic work environments. A strong, simple design with lockable steel doors provides rugged security and storage while inside, an electrical assembly and cord management system keep things organized and charged up. Rubber-coated dividers won't scratch devices and help provide impact protection during transit, which is made easy even when fully loaded thanks to rolling casters and a full-length handle. And the cabinet requires minimal assembly – simply attach the casters and handle.
