[INDICATOR LIGHT] Equipped with power indicator for easy monitoring, shows connection status and capacitor voltage accurately. Specification: Item Type: Super Capacitor UPS for RPI Material: PCB Power Input: 9-24VDC DC power socket or KF128 terminal) Power Output: 5VDC (USB 2.0 or KF128 terminal), maximum current 5V3A Super Capacitor: 25F Charging Current: limited to 1.4A, about 3min to fully charge capacitor Discharge Current: 5V3A (continuous) when connected to external power supply, 5V3A (within 10s) when only super capacitor output Power Down Detection: 2.54mmx2p, 3V indicates external power source, 0V indicates power loss Power Indication: DCIN green indicates external power source connection, 5V OUT red indicates 5V output, Vcap green light brightness changes with capacitor voltage. Brightest when capacitor is full, off when capacitor is discharged Product Size: Approx. 90 x 56mm / 3.5 x 2.2in Locating Hole: Approx. 3.5mm / 0.14in How to Use: Insert external power supply to output 5V and charge the super capacitor at the same time. The higher the voltage of the super capacitor, the brighter the Vcap green LED will shine. It is expected to be fully charged in 3 minutes, 5.4V for two fully charged super capacitors, and 2.7V for a single one.If the external power supply is disconnected, the DC IN red LED will go off after the external power supply capacitor is discharged, and the DC IN signal on the terminal will change from 3V to 0V. At this point, the super capacitor will quickly discharge to maintain the output voltage at 5V. The duration of maintaining 5V is inversely proportional to the output current. The higher the output current, the shorter the 5V holding time. At 3A, it can only hold for 5‑6s, while in cases of very small current, it can hold for several minutes or more.
