Power Pack is not fully charged

The average charging time to fully recharge your Power Pack is approximately ten hours. During the charging process, the LED of your Power Pack flashes once per second. When the Nuki Power Pack is fully charged, the LED turns off.

Please note that the Power Pack reaches the full charging capacity after 2-3 charging processes. The charging process is only started when the charge level has dropped below 75%. This is to protect the battery.

If your Power Pack does not charge or does not charge sufficiently, check the following troubleshooting steps:

Battery type
Check the set battery type in the Nuki app. To do so, tap on the desired Smart Lock in the Nuki app and open the settings. Then go to “Manage Smart Lock” > “Battery type”. Set the Battery type manually to “Nuki Power Pack”.

Problems can sometimes occur due to outdated software. Therefore, check whether the latest software version is installed on your Smart Lock. To do so, tap on the desired Smart Lock in the Nuki app and enter the lock settings. Then go to “Manage Smart Lock” and choose “Firmware update”. Then follow the instructions in the Nuki app to update the firmware of your Smart Lock.

Power supply unit
We recommend to use the Nuki charging cable, which is included with your order.

Nuki does not support fast charging (Power Delivery). Therefore, charging the Nuki Power Pack with a modern charger that uses the so-called Power Delivery technology may not work successfully. This does not apply to all of these chargers. However, if you have difficulties charging the Power Pack, it is advisable to test a different power supply unit to rule out compatibility issues.

Note: Your Nuki Power Pack will be delivered pre-charged. Therefore, there is usually no need to charge your Nuki Power Pack after receiving it. If you still want to charge your Power Pack, please keep in mind that the charging process will not be started as long as the Power Pack's charge level is still above 75%.
We have also observed that under certain circumstances, the Power Pack is only fully charged after two to three charging cycles.
