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.
The charging process will only start when the charge level has fallen below 75%. This is to protect the battery.
To charge your Nuki Power Pack, we recommend always using the Nuki charging cable included with your order. Also note that power supplies differ in quality and functionality.
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, to rule out compatibility issues when charging the Power Pack, we recommend testing different chargers.
