One port is not charging or an LED stays off

1. Test this port with another cable and another device. This shows whether the port, the cable or the device is the cause.
2. If the LED stays off although a device is connected: unplug the cable briefly and plug it in again.
3. Disconnect the cart from the power once, wait 60 seconds and reconnect it.
4. Note the port number and what the LED does (off, colour, blinking).

If the port still does not work, please create a ticket with the serial number and the port number. A photo of the LED panel helps us a lot.
