Waveshare Mini Uninterruptible Power Supply Module, 5V 2.5A Output

An unexpected power interruption, however brief, can corrupt an SD card or interrupt a critical process on a single-board computer that has no battery backup of its own. This mini UPS module bridges that gap, supplying 5V at up to 2.5A to keep a Pi-class board running during a short outage while simultaneously managing its own battery charging, so it's always ready for the next interruption without needing to be manually recharged between events. Compact enough to fit alongside a Pi in a typical project enclosure, it's a sensible addition to any deployment where a clean shutdown - or simply staying online through a flicker - actually matters.
