Lockin's V7 Max aims to make smart locks truly battery-free

In the world of connected home hardware, the V7 Max represents a bold shift toward eliminating the little power packs that have long haunted smart-lock owners. Inside Lockin's R&D studio, designers have paired a sleek optical charging pad with a trio of biometric sensors, letting the lock harvest energy from a simple wireless beam while confirming identity through fingerprint, facial scan and an additional modality that feels like a silent gesture. The result is a device that can sit on a door for years without a single battery swap, a promise that resonates with installers tired of field calls for dead units and with residents who crave a set-and-forget security solution. Early users describe the experience as seamless: the lock powers up as soon as the homeowner's phone or wearable passes by, and the layered authentication feels both futuristic and reassuring. By removing the need for periodic maintenance, the V7 Max could set a new benchmark for reliability in a market where uptime is everything, and it hints at a future where other IoT fixtures might follow suit, trading disposable cells for continuous, invisible power.
