This is a compact DC UPS designed to connect inline with your ordinary 12VDC mains power adaptor. In the event of a power outage, the internal battery will keep your equipment operating.

Three interchangeable DC connectors are supplied to suit a range of devices such as modems, network switches, routers, video devices, surveillance systems or lights.

An integrated smart charger ensures the internal 18650 Li-ion batteries are charged, and adjusts the charge current based on the current draw to the device you are powering.

The rated output is 2.5A at 12V but 3A can be provided for a short time. Four status LEDs indicate the UPS charge status, and safety features include over-charge, over-discharge, over-current, and short-circuit.
