How long will I get along with a full charge of the Power Pack?

The Nuki Power Pack is equipped with a total charging capacity of 2500 mAh (4.8V DC | 2.5Ah | 12 Wh).

For an optimal power supply of your Smart Lock we recommend the Nuki Power Pack. With this rechargeable battery pack, the battery life is much longer than standard alkaline batteries and it is also more environmentally friendly than alkaline batteries.
In addition, the Power Pack enables a permanent power supply for your Smart Lock. 
With an average use with 8-10 locking processes per day, the Nuki Power Pack will last up to 6 months until it is completely empty.
