"This biometric smart lock features wireless optical charging technology, eliminating the need to replace or recharge batteries altogether. Called AuraCharge technology, the V7 Max receives power from an optical output device plugged in within four meters' distance to wirelessly recharge its internal battery. Power is sent from within the house using an eye-safe controlled light beam that reaches the lock's receiver, which is then converted into electricity to recharge and power the smart lock."
"Imagine solar panels capturing available solar energy like a cup placed outside to collect water during a rain. In this analogy, wireless optical charging would be like filling the cup with a hose that is aimed directly at it. This makes wireless optical charging a nearly perfect solution for smaller, static, battery-powered smart home devices, such as sensors or, in this case, smart locks."
The Lockin V7 Max is a biometric smart lock that uses wireless optical AuraCharge technology to eliminate the need for disposable or rechargeable batteries. An optical output device placed within four meters transmits an eye-safe controlled light beam to the lock's receiver, which converts the beam into electricity to recharge and power the internal battery. AuraCharge supplies continuous power without dependence on ambient light or manual charging, distinguishing it from solar approaches like perovskite that require light. The V7 Max is expected to launch in the US, with preorders open now and units shipping in March.
