Do more than just charge your teaching devices. With the Zip40 charging cart, batteries last longer and charge faster. This charging cart now features a sturdier handle, a removable door, and double wheels, allowing you to navigate through crowded classrooms with ease. Thanks to the adjustable dividers, you can accommodate up to 40 tablets and Chromebooks or 30 standard-sized laptops. It comes fully assembled so you can focus on what really matters - your students.
