Construction site environments are harsh and complex, with dust storms, heavy object collisions, fluctuating temperatures, and oil splattering being commonplace. The continuous power supply for 12.8V equipment (such as measuring instruments, walkie-talkies, small power tools, and monitoring terminals) directly impacts construction progress and work safety. Ordinary chargers are prone to malfunction due to environmental corrosion and accidental impacts. The core requirements for chargers on construction sites are "robust durability, precise compatibility, safety and stability, and adaptability to extreme working conditions." We have custom-designed a durable 12.8V charger specifically for construction site equipment—overcoming environmental constraints with industrial-grade durability, empowering construction scenarios with precise and fast charging, ensuring reliable and worry-free power supply every time, and facilitating efficient construction.

　　Born for construction sites, designed for durability

　　Industrial-grade durable materials, stress-free resistance: Featuring a military-grade aluminum alloy shell and internal shock-absorbing structure, it has passed a 1.5-meter drop test and a 500-hour salt spray corrosion test, easily withstanding extreme conditions such as heavy object impacts, machinery crushing, and gravel friction on construction sites. The shell is treated with an oil-resistant coating, allowing for direct washing of oil and cement slurry, and it is not easily deformed or damaged over long-term use.

　　IP66 three-proof protection, fearless of harsh environments: Achieving an IP66 dustproof and waterproof rating, it completely blocks dust intrusion and can withstand strong water jets, suitable for construction site dust, rainy weather operations, and open-air storage. The sealed interface design prevents mud and oil from seeping into the internal circuitry, avoiding short-circuit failures.

　　12.8V Precise Compatibility, Suitable for All Construction Site Equipment: Designed specifically for 12.8V lithium iron phosphate power batteries, it perfectly matches core tools such as construction site walkie-talkies, total stations, laser rangefinders, small electric wrenches, and emergency lighting equipment. With a charging conversion rate exceeding 93%, it complies with EN 62368-1 industrial safety standards, preventing equipment damage or inefficient charging due to voltage mismatch.

　　Wide Temperature Range and Stable Operation, Adaptable to Extreme Conditions: Operating within a temperature range of -20℃ to 60℃, it provides stable power output in both high-temperature, sun-exposed construction sites and low-temperature, harsh winter construction environments. Supporting a wide voltage input range of 85-264V, it adapts to temporary power grid fluctuations on construction sites, eliminating charging interruptions caused by voltage instability.

　　Multiple safety protections for worry-free use on construction sites: Built-in six safety protection systems including overcharge, overheat, short circuit, overload, surge protection, and undervoltage protection, suitable for the complex electrical environment of construction sites; EMC electromagnetic compatibility certified (EN 55032 standard), preventing electromagnetic interference generated during charging from affecting the normal operation of site measuring instruments and communication equipment.

　　Adaptable to diverse construction site scenarios

　　Daily equipment charging: Provides daily charging for 12.8V equipment such as site inspection walkie-talkies, surveying instruments, smart safety helmets, and monitoring cameras, allowing for on-demand charging and ensuring uninterrupted construction communication and data collection.

　　Outdoor construction power replenishment: In foundation pits and high-altitude work areas without fixed power supply points, quickly replenish batteries for small power tools and emergency lights via a vehicle power supply or temporary distribution box, without delaying construction progress.

　　Emergency backup: In the event of a sudden power outage or low equipment power, quickly charge critical equipment (such as emergency lighting, communication terminals, and safety monitoring equipment) to avoid work stoppages or safety risks due to power outages.

　　Multi-device rotation power supply: Supports simultaneous charging of 2 12.8V devices (dual interface design), meeting the centralized power replenishment needs of multi-person collaborative scenarios on construction sites and improving team work efficiency.
