Feature:1. Product Use: This super capacitor uninterruptible power supply is designed for high reliability scenes. When the external power supply unexpectedly loses power, it will quickly switch to super capacitor discharge.2. Endurance and Save: This uninterruptible power supply can provide a power down endurance time of 1060 seconds and output an external power down signal, which is sufficient for on site data storage.3. Input and Output: The power supply input is 94V DC (5.5x2.1mm DC power socket or KF128 terminal), and the power supply output is 5V DC (USB 2.0 or KF128 terminal), with a maximum current of 5V 3A.4. Indicator Light: This UPS is equipped with power indicator. DC IN green indicates connection to an external power source, 5V OUT red indicates 5V output, and Vcap green light brightness varies with capacitor voltage.5. Compact and Practical: This uninterruptible power supply has a compact size and lightweight design, features a size of 90x56mm, with 3.5mm locating hole for easy connection and use.Specification:Item Type: Super Capacitor UPS for RPIMaterial: PCBPower Input: 9-24VDC (5.5x2.1mm DC power socket or KF128 terminal)Power Output: 5VDC (USB 2.0 or KF128 terminal), maximum current 5V3ASuper Capacitor: 25FCharging Current: limited to 1.4A, about 3min to fully charge capacitorDischarge Current: 5V3A (continuous) when connected to external power supply, 5V3A (within 10s) when only super capacitor outputPower Down Detection: 2.54mmx2p, 3V indicates external power source, 0V indicates power lossPower 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 dischargedProduct Size: Approx. 90 x 56mm / 3.5 x 2.2inLocating Hole: Approx. 3.5mm / 0.14in.Package List:1 x Super Capacitor UPS
