GoKawiilRing unveils its first smart lock with a hand-crank backup power system
Ring announced its debut smart lock, which includes a built-in supercapacitor-based crank below the keypad that can be manually spun to generate about 20 seconds of power when the battery dies. CEO Jamie Siminoff demonstrated the device, showing it works even with the battery fully removed, eliminating the need for a physical key or external charger as a backup.
