パワーパック

Installing this took two minutes and the fact it's rechargeable instead of a one-time battery has already saved me from buying spares. Setup with the lock was seamless, and I love that I can keep the door working without worrying about a dead battery on a random weeknight.

Charging this once lasted me over two months of daily lock use, and it popped right into the lock without any fuss. The peace of mind from knowing I don’t have to swap AA batteries in the dark is totally worth it.

Finally stopped worrying about the lock dying mid-week. This rechargeable pack clicks in cleanly and keeps the Nuki going for months, and the USB charging is a lifesaver compared to buying batteries every few weeks.
