Enhanced safety features: Includes short circuit, overvoltage, and undervoltage protections to guard both the load and the battery, helping ensure the load can resume operation after a fault. Efficient charging design: Two battery sockets plus a micro USB charging port and a DC 5V input support quick lithium battery charging, offering flexible charging options. capacity UPS battery boost: An integrated UPS circuit enables seamless power switching between external power and the battery with no delay, providing uninterrupted power to the connected load. Charging indicator: A color LED shows charging status; green stays on when fully charged and charging stops automatically for added safety and convenience. Key benefits at a glance: Protects equipment from electrical faults, reduces downtime with instant power switching, and provides clear charging feedback for reliable operation. Practical use scenarios: Home or small office: keep essential devices such as routers, modems, and small electronics powered during brief outages. Workshop or field setup: maintain power to sensors, cameras, or measurement devices where uninterrupted supply is critical. Portable charging and standby setups: recharge lithium batteries quickly via micro USB or DC 5V input, then rely on the UPS during periods without external power.
