    • Unplug your router from power and wait about 10 seconds.
    • Plug the router back into power and wait about 1 minute.
    • Check your iOS device’s Wi-Fi settings to make sure it reconnected to the right network.

My cable does not charge my iOS device through the iDynamo.

This could be caused by a problem with your power adapter, power outlet, micro USB cable, or iDynamo.

Power Adapter / Outlet

  1. Check that the cable plugged into the iDynamo is connected to the power adapter that came with the iOS device.

    Other power adapters may not provide enough energy to charge the device.

  2. Plug the power adapter into a different wall outlet to test if the outlet itself could be the problem.

Micro USB Cable

  1. Connect a different micro USB cable to the iDynamo.

    If this charges the device, then you know the original cable is broken.

  2. Use your existing micro USB cable to charge a different device.

    If you experience problems charging the second device, the cable is your problem.

  3. Unplug the cable from the iDynamo before rotating your stand.

    Leaving your cable plugged in while rotating the stand can cause stress on the cable and iDynamo.

iDynamo

  1. Try plugging a Lightning cable directly into the iOS device's charging port.
    • If the device charges with its own cable, the problem could lie with your iDynamo. Contact support for further assistance.
    • If the device still won’t charge, there may be an issue with its charging port. Contact Apple for help.
