Enhancing Charging Locker Security with Advanced Electronic Password Locks
Effectively addressing users' "battery anxiety", mobile phone charging lockers are becoming standard infrastructure in public spaces.
After Company B adopted MAKE Security's electronic password locks for its mobile phone charging locker project, the project lead commented:
Since the installation of the MK-E750, overall performance has been stable and reliable, meeting our core selection requirements for electronic password locks — high security and low power consumption. The product competitiveness of our mobile phone charging lockers has been enhanced, and end-user satisfaction has also improved.

High security and long battery life are hard to achieve simultaneously.
Company B is a Chinese office furniture manufacturer with decades of experience, offering one-stop OEM and ODM services. It produces a wide range of steel products including filing cabinets, storage lockers and smart charging lockers, widely deployed in furniture, industrial, education and other sectors.
Previously, Company B used electronic password locks from other brands, which suffered high power consumption and required frequent maintenance. While searching for alternatives, it struggled to find genuinely secure and reliable products.

A single lock delivering both premium security protection and ultra-long battery life
Charging lockers deployed in public spaces provide users with secure storage and charging services for mobile phones. The installed locks face two major challenges:
High security risks: Unattended open environments make locks a critical line of defence.
High usage frequency: Daily frequent opening and closing accelerates battery drain of locks.
Therefore, Company B set two core requirements for electronic password lock procurement:
High security rating to meet anti-theft demands in public areas, effectively resisting both technical lock picking and physical break-in attempts.
Ultra-low power consumption design to achieve long service cycles and low maintenance workloads.

Two Core Advantages of the Electronic Password Lock
After fully understanding Company B's actual demands for security and power efficiency, MAKE Security delivered a customised solution: the MK-E750 electronic password lock. Boasting two core strengths — reliable security and long-lasting battery life, it helps upgrade the quality of charging lockers.

Each compartment of the charging locker is fitted with an independent high-security lock, with a shared usage mode available to facilitate efficient operation. The lock brings two key benefits:
On one hand, access via 4-digit passwords plus a robust zinc alloy housing safeguards mobile phones stored inside lockers.
On the other hand, passwords automatically expire once users retrieve their phones. Vacant compartments are released immediately for seamless use by subsequent users.
The lock adopts low-power design with outstanding energy efficiency, easily coping with heavy usage of shared charging lockers and cutting maintenance costs.
Equipped with high-performance chips, the lock maintains low energy consumption in both working and standby modes. Powered by a CR2032 coin lithium battery, it can operate for up to 3 years under room temperature.
MAKE Security's electronic password locks redefine the lock standards for shared charging lockers and elevate product and service quality to new heights.
