- Smart Lock 4th Generation
- All previous generations
Charge your Nuki Power Pack using one of the integrated USB Type-C ports. To see if your Power Pack is charging, simply check that the white LED on the Power Pack is flashing. You can also charge the Nuki Power Pack directly in the Smart Lock or on the door. This means you can keep your Smart Lock permanently connected to the power supply and use it while charging.
If your Power Pack does not charge sufficiently, check the following troubleshooting steps:
Power supply unit for the Power Pack
We recommend charging your Power Pack with the enclosed USB cable before first use. For optimal performance, we recommend the Amazon 5W USB Original Charger and Power Adapter.
If you bought your Smart Lock or Power Pack before July 2024: It 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. The new Power Packs (sold after July 2024) support this technology. Therefore, you can charge your Power Pack even faster.
Firmware Update
Problems can sometimes occur due to outdated software. Therefore, check whether the latest firmware version is installed on your Smart Lock. To do so, tap on your Smart Lock in the Nuki App and enter the lock settings. Then go to “Features & Configuration” and choose “Firmware update”. Then, follow the instructions in the Nuki App to update your Smart Lock firmware.
We recommend allowing automatic firmware updates to keep your device up to date.
If you plug in the Nuki Power Pack for charging while the battery of the Power Pack is still over 75%, the charging process does not start. This is to protect the battery.
