If the battery has died completely (for example, after not using the device in the winter or not being exposed to sunlight), it can take up to 24 hours (in come cases, more than 24 hours) for the unit to come back online.
- Please plug in the device using the provided power cable and ensure it is plugged in for at least 24 hours.
- You know if the device is charging successfully because the LED light will glow red (note, it may take some time for the LED to turn on if the battery has been dead for an extended period of time).
- Note: if the battery is very low the device can generally not get enough power from the sun alone. We suggest you plug it in for 24 hours so you can work with a full charge.
