Your Ringly takes approximately 4 hours to fully charge when placed in the charging box. The Ringly pulses a red light every 5 seconds when it is actively charging. When it's finished charging, it will flash green once and then stop flashing.
If you want to test if your Ringly is fully charged, you can drop it into the charge box and if it flashes green, voilà, fully charged! If you don’t think your Ringly is charging, make sure the box is plugged into a usb port.
