Super Capacitor UPS HAT for Raspberry Pi, 5V 3A Uninterruptible Power Supply, 10-60 Seconds Power Backup, Safe Shutdown & Power Failure Protection, Compatible with Raspberry Pi 5/4/3B+

Product Dimensions: 90*56mm Weight: 44G Positioning Hole: 3mm Power Input: 9~24V DC (5.5*2.1mm DC power socket or KF128 terminal block) Power Output: 5V DC (USB2.0 or KF128 terminal block), maximum current 5V 3A Supercapacitor: 25F, 2 strings Charging Current: Limited to 0.7A, fully charging takes approximately 6 minutes Discharging Current: 5V 3A (continuous) when connected to an external power source, only the supercapacitor outputs 5V 3A (within 10 seconds) Power-Off Detection: 2.54mm*2p, 3V indicates external power is available, 0V indicates external power is lost Power Indicators: DC_IN (green) indicates external power is connected 5V_OUT (red) indicates 5V is being output Vcap green LED brightness varies with capacitor voltage. Brightest when the capacitor is fully charged, off when the capacitor is de-energized Instructions for Use: Plug in an external power source to output 5V and charge the supercapacitor simultaneously. The higher the supercapacitor voltage, the brighter the Vcap green LED. It is estimated that it will fully charge in 6 minutes. Two fully charged supercapacitors will provide 5.4V, and a single supercapacitor will provide 2.7V. If the external power supply is disconnected, the red DC_IN LED will turn off after the external power supply capacitor has discharged, and the DC_IN signal on the terminal will change from 3V to 0V. At this time, the supercapacitor will quickly discharge, maintaining the output voltage at 5V. The holding time of 5V is negatively correlated with the output current. The higher the output current, the shorter the holding time of 5V. At 3A, it can only maintain 5-6 seconds, but at very low currents, it can even maintain 5V for several minutes or more.
