The DC4032 is a DC UPS designed for home and small office networks. It houses four brand-new 26700 LiFePO4 cells (total energy: 64Wh) and offers a total output of 40W with voltage options including 5V, 9V, 12V, and USB-C PD. In the event of a mains power failure, it switches to battery power with zero latency, ensuring that critical devices such as optical modems, routers, and surveillance cameras—do not reboot and data is not lost.
It utilizes intelligent CPU control, resettable thermal fuses, and multiple electrical protection mechanisms to ensure safety and reliability. An RS485 interface allows for real-time monitoring of battery status, facilitating integration into smart home or remote monitoring systems.
The 40W Mini DC UPS features intelligent CPU control and comprehensive protections against overheating, overcurrent, and short circuits. It supports zero-latency automatic switching between mains power and battery power, ensuring devices remain operational without rebooting or data loss during outages. The product uses brand-new 26700 cylindrical cells—avoiding recycled cells to ensure a longer lifespan and superior safety.

The 40W Mini DC UPS provides four DC5521 ports (two 12V/2A, one 12V/2A, and one 9V/2A), one USB-A port (5V/2A), and one USB-C PD3.0 port (supporting 5V/3A, 9V/2.7A, and 12V/2.08A; max. 25W). It can simultaneously power devices such as optical modems (ONTs), routers, IP cameras, LED displays, and time-and-attendance terminals, or power two 12V devices at the same time.
When mains power is available, the UPS automatically charges its internal battery while supplying power directly to the load. In the event of a power outage, it switches to battery power instantly without delay; connected devices do not need to reboot, ensuring the continuous operation of network and surveillance systems.
Utilizes four brand-new, high-quality 3.2V/5000mAh 26700 cylindrical LiFePO4 cells (configured in parallel to provide 3.2V/20000mAh, 64Wh). Compared to recycled 18650 cells, these offer a longer cycle life and superior thermal stability. A built-in Battery Management System (BMS) prevents overcharging, over-discharging, and overcurrent.
Uses an advanced microprocessor or dedicated IC to control each output channel, ensuring stable voltage and low ripple—making it suitable for sensitive electronic equipment. Features resettable thermal fuses for independent thermal protection on each channel, allowing for automatic recovery after an over-temperature event.
Equipped with SMT-mounted battery level indicators (5-level display + blue "fully charged" indicator + red "charging" indicator) for real-time monitoring of battery capacity. Includes an RS485 interface to read charging status, battery percentage, and low-battery alarms, facilitating integration into surveillance or smart home systems.
Features protections against short circuits, overloads, overheating, overcharging, and overcurrent, ensuring the safety of both the connected devices and the UPS itself. Operates within a temperature range of -10°C to 40°C, making it suitable for most indoor environments.
Provides uninterruptible power for optical modems (ONTs), wireless routers, and network switches, preventing internet disconnection during power outages and ensuring the continuous availability of remote work, online education, and smart home control systems.
Provides backup power for DC-powered cameras (typically 12V or 9V), ensuring uninterrupted surveillance and continuous recording during power outages; ideal for shops, warehouses, villas, and similar locations.
Suitable for devices such as VoIP phones, wireless bridges, and 4G/5G CPEs, providing short-term backup power for communication base stations in outdoor or remote areas.
Delivers stable DC power and power-loss protection for time-and-attendance terminals, POS machines, small LED displays, portable medical devices, and more.
When used with PoE splitters or injectors, it provides backup power for standard PoE devices (e.g., IP phones, wireless APs), making it suitable for low-voltage system installations.

A: It features a built-in 64Wh battery. For a typical router (12V/1A, approx. 12W), the backup time is about 5 hours; if powering both an optical modem (approx. 6W) and a router (total load approx. 18W), the backup time is about 3.5 hours. Actual runtime depends on the load power and battery health.
A: No. The DC4032 automatically switches back to mains power while simultaneously charging the battery; the connected device does not need to restart, ensuring a seamless transition.
A: Yes. The USB-C port supports the PD3.0 protocol with a maximum output of 25W, capable of providing emergency power to phones, tablets, and even some laptops (e.g., MacBook Air). Note, however, that the total output power cannot exceed 40W.
4. Is the battery replaceable? A: The internal battery consists of four 26700 LiFePO4 cells connected via professional welding tabs. Users cannot replace the battery themselves, but battery module replacement services are available through after-sales support.
A: The front panel features a 5-level green LED battery level indicator (25%–95%) and a blue "fully charged" indicator. Additionally, the RS485 port outputs detailed status data; an external RS485-to-USB module is required to connect to a computer or serial display.
A: It has an operating temperature range of -10°C to 40°C and lacks waterproofing; therefore, installation indoors or inside a waterproof enclosure is recommended.
