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.
“While third-generation power solutions like perovskite solar offer promising innovation, the technology continues to rely on adequate light to function reliably. AuraCharge requires no light, no manual charging, and provides an infinite power supply,” said Bill Chen, founder and CEO of Lockin. “We’re thrilled to offer users a new level of freedom and security with a smart lock they can install once, and never worry about again.”
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.

Aside from this optical charging innovation, the Lockin V7 Max, supports multiple biometric security measures to unlock, including finger and palm vein and 3D facial recognition. Supported by two HD exterior cameras with a panoramic view that make it function like a video doorbell, the smart lock features dual five-inch touchscreens for enhanced visibility.
Lockin hasn’t announced a price for the V7 Max, but the smart lock will be available for preorder in January, with orders shipping in early March.
