Our Chromebook cart is only charging on one side. I think its broken.
It is not broken. The Anthro Chromebook cart has a built-in system that alternates power from one side of the cart to the other to manage its power draw. It does it automatically so you don't need to. If it charged both sides at the same time it would trip circuit breakers!
You can adjust the amount of time each side charges (before it switches back) using the timer on the cart. It is located on the right hand side where the plugs are on the bottom of the cart. We recommend setting it somewhere between 15 and 30 minutes.
