Product description
UPS HAT – Robust Power Supply for Raspberry Pi. UPS add-on for Raspberry Pi 5/4/3B+, designed for long-term operation. Seamlessly switches between external power and battery operation without interruption. With safe shutdown of the Raspberry Pi in case of low battery.
Ideal for applications where uninterrupted operation is critical, such as IoT gateways, remote servers, data loggers, or network monitoring. Provides up to approximately 2 hours of runtime under full load, depending on battery capacity.
Powered by four 21700 Li-ion cells (not included). Recommended cells: 41022129 or 41032020. The module delivers 5 V / 6 A to the Raspberry Pi via pogo pins.
