The Mini Router UPS Circuit Board 40W V2.6 is a compact and efficient uninterrupted power supply (UPS) module designed to keep your router, modem, or small network devices running during power outages. With support for up to 40 watts of power, this smart circuit ensures your internet stays online during load-shedding or blackouts—ideal for work-from-home users, gamers, and smart home setups.

This Version 2.6 board features improved power efficiency, better thermal performance, and smart switching between main power and battery backup. It is designed to work seamlessly with 12V batteries and 12V-powered routers.

How It Works:
The UPS board connects between your DC power source (like a 12V adapter) and your router. It charges the battery while mains power is present and instantly switches to battery backup during a power failure—without resetting or rebooting your router. The built-in protection circuits safeguard your devices from overcharging, short circuits, and reverse polarity.
