If you place your glasses in the case, but the white charging LED doesn't light up, please give the following steps a try, making sure to follow the steps exactly:
1. Take the glasses fully out of the case.
2. Plug in the case to a wall adaptor with more than 1A of charge. Charge for 30 minutes.
3. (Important) With the glasses out of the case, unplug the USB cable from the case.
4. Put your glasses in the case.
This should allow the glasses to charge, and you should be able to use the case normally henceforth. If the case's battery drains completely, you may have to do the above again to restart it.
If the above doesn't work, please email us.
