With smart homes becoming increasingly popular, electronic door locks have become a standard feature for modern households. However, battery life has long been one of the biggest pain points for users—forgetting to charge, depleted batteries, and sudden power failure preventing unlocking are common issues that not only affect the user experience but can also pose security risks.
In 2026, Lockin launched its flagship new product, the V7 Max True AI smart electronic door lock. Equipped with the world's first AuraCharge™ wireless charging technology, it completely overturns traditional power supply models, achieving a revolutionary breakthrough in infinite battery life. This article will provide an in-depth analysis of how this technology works, its advantages, and why the V7 Max is set to become the new benchmark in the smart door lock market.
What is wireless charging? How does the Lockin V7 Max eliminate the need for manual charging?
The power supply dilemma of traditional smart door locks
Most smart door locks on the market rely on built-in lithium batteries, with an average battery life of about 6 to 12 months. Users must periodically remove the batteries for charging or replacement; if they forget, they risk the door lock failing to function. While some products support USB emergency power or solar charging, the former requires manual intervention, and the latter is limited by lighting conditions, making it impossible to guarantee a stable power supply.
AuraCharge™ Technology: The revolution of infrared wireless power transfer
The AuraCharge™ wireless charging technology used in the Lockin V7 Max is an innovative solution based on Wireless Optical Power Transmission. Its core principles are as follows:
- Transmitter: A small wall-mounted or desktop device that connects to an indoor power outlet and continuously emits infrared light beams of a specific wavelength.
- Receiver: The interior panel of the V7 Max door lock is equipped with a micro-optical energy receiving panel capable of converting incoming infrared energy into electrical energy.
- Energy Conversion: The receiving panel features a built-in high-efficiency photoelectric conversion module that transforms infrared energy into DC power, continuously charging the door lock's 6735mAh main battery and 2500mAh backup battery.
- Smart Control: The system includes an automatic sensing function that lowers power or pauses transmission when the light beam is obstructed by a person or object, ensuring safety; power transmission resumes immediately once the obstruction is removed.
The effective transmission distance of this technology is up to 4 meters, meaning the transmitter can be flexibly installed at various heights near the door, provided there is a line-of-sight to the door lock, allowing for a stable power supply.
Why choose infrared? Technical advantages of wireless charging
1. Double international certification for safety
Infrared light is non-ionizing radiation with energy far lower than visible light, causing no harm to humans or pets. Lockin's AuraCharge technology has passed safety certifications from two major international authorities, Germany's TÜV Rheinland and SGS, confirming that it is harmless to eyes and skin during long-term use and can operate stably for over 10 years.
2. Unaffected by ambient light
Unlike solar charging, infrared wireless charging does not rely on natural light or indoor lighting; it works normally even in complete darkness. This makes the V7 Max suitable for various home layouts, including hallways without windows or basements with insufficient light.
3. High-efficiency energy conversion
AuraCharge technology uses infrared light at specific wavelengths (approximately 850-940nm). This wavelength experiences minimal loss during transmission through the air and can be efficiently absorbed and converted by the photoelectric receiver panel. According to official data, even at a distance of 4 meters, it maintains sufficient charging power to keep the door lock's batteries in a fully charged state.
4. Flexible installation, suitable for various door types
The transmitter supports wall mounting or desktop placement, allowing users to choose the optimal location based on their home layout. The V7 Max itself is available in left-opening and right-opening versions and comes in a Space Grey finish, perfectly integrating with modern interior design.
What are the practical benefits of wireless charging?
1. Say goodbye to battery anxiety
The dual-battery system (6735mAh + 2500mAh) of the V7 Max, combined with continuous wireless charging, theoretically achieves infinite battery life. Even if the transmitter loses power due to special circumstances (such as being away for a long time), the built-in batteries can independently operate for up to a week, providing ample buffer time.
2. Reduced maintenance costs
There is no need to periodically remove batteries for charging or purchase replacements, saving time and money in the long run. For rental properties, Airbnb hosts, or commercial venue managers, this significantly lowers management costs.
3. Enhanced user experience
Users no longer need to worry about the sudden issue of a door lock running out of power. This feature is particularly practical for the elderly, individuals with limited mobility, or users who frequently forget to charge their devices.
4. Environmental sustainability
Reducing the use of disposable batteries aligns with the global trend toward green living. Furthermore, the high-efficiency design of the V7 Max reduces overall power consumption.
Other core highlights of the Lockin V7 Max
Beyond its revolutionary wireless charging technology, the V7 Max excels in security, smart features, and design aesthetics:
1. True AI smart applications
- Palm Vein Recognition: Uses palm vein patterns for biometric authentication, with anti-counterfeiting capabilities far superior to traditional fingerprints.
- 3D Structured Light Facial Recognition: Supports scenarios with masks, glasses, and hats, with recognition speeds as fast as 0.5 seconds.
- Finger Vein Recognition: Combines fingerprint and vein verification for upgraded security.
- Advanced Outdoor Peephole Pre-recording: Automatically records when someone lingers outside the door and pushes notifications to the mobile app.
2. 5-inch dual-touch HD screen
The interior panel is equipped with a 5-inch, 720×1280 resolution touchscreen, allowing for real-time viewing of footage outside the door, menu navigation, and system notifications—intuitive and convenient to operate.
3. 15mm ultra-slim panel design
Designed by a former Apple lead designer, the V7 Max features a minimalist, streamlined appearance. With a front panel thickness of only 15.1mm, it combines technological appeal with aesthetic value, winning the 2026 CES Innovation Design Award.
4. Multiple unlocking methods
Supports up to 10 unlocking methods, including palm vein, finger vein, 3D face, password, mechanical key, remote app unlocking, and NFC key card (optional), meeting various user needs.
5. Localized service support
The V7 Max purchased via EasyLock comes with original manufacturer warranty, which takes effect once users complete their online registration after purchase.
The story behind the technology: From military radar to smart home
Interestingly, the inspiration for AuraCharge wireless charging technology comes from military laser-based wireless energy transfer systems, originally used to provide long-distance power to high-altitude drones or satellites. The Lockin engineering team miniaturized and optimized this technology, making it safe for home use and creating the world's first mass-produced wireless charging smart door lock.
This breakthrough not only represents a technological leap in the smart door lock industry but also heralds a new era where smart home devices will gradually shed the constraints of wires and batteries.
