ITEM DETAILS- This image is of a Mini UPS (Uninterruptible Power Supply) circuit board designed to provide backup power for devices like routers and modems. Here's a breakdown: What it is: Function: This circuit board acts as a mini UPS, ensuring that your devices stay powered during a power outage. It does this by using a battery as a backup power source. Input: It takes a DC input voltage, typically between 5V and 12V, which is used to charge the battery and power the device when mains power is available. Output: It provides a stable DC output voltage, usually 9V or 12V, suitable for powering routers and similar devices. Battery: It is designed to work with a 3.7V or 4.2V Lithium battery (like an 18650 battery). Key features: Step-up Boost Converter: The board includes a step-up boost converter to increase the voltage.
