Nuki power pack
Product rating for Nuki power pack
No more changing batteries...
I just installed the battery, not yet back, but still much more practical than the batteries that must be changed 4 to 6 times a year at home!
The frequency of charging is the same for me as changing the batteries and after a year, the batteries only last 2 or 3 weeks...
Not to mention the fact that from one opening to the next, there is suddenly not enough juice to open the door without any warning...
I'll come back to the batteries.
