The DORY lock is designed to be a wireless device, so it does not have any cable to connect to the power supply but is powered by two normal CR2 batteries included in the package.
The batteries have an average life of about a year under normal conditions of use and it is always possible to check the charging status from the app. Replacement is very simple and CR2 batteries are a very common model, which you can even find in the supermarket.
The independence from the external power supply also guarantees opening in any situation, even in the absence of electricity.
