2PCS Type-C 15W 3A 5V Fast Charge UPS Power Supply 18650 Lithium Battery Charger Module DC-DC Step Up Booster Converter
Brand: JUZITAOBattery Cell Composition: LithiumProduct Dimensions: 3.46D x 1.61W x 0.87HVoltage: 5 VoltsColor: 5VThe UPS Power Supply Converter module integrates four practical functions of lithium battery charging, lithium battery protection, boost output, and UPS switching.UPS function: When the power supply is powered on, the power supply directly supplies power to the load via the booster circuit, and simultaneously charges the lithium battery. Once the power is cut off, the battery path is automatically activated to supply power to the load via the boost circuit.Power Switching: Booster converter module can realize the seamless switching of external power supply and battery dual power supply (no delay), suitable for uninterrupted power supply schemes such as low-power DC equipment and meters, and self-start after power failure and self-charge when power is received.LED Indicator: The Fast Charge module features a dual-color LED indicator, with the green light remaining continuously lit when the battery is fully charged, and the charging process automatically ceases.Lithium battery protection: Over-charge, over-discharge, over-temperature, over-current protection (if it enters the protection state and does not output after a short-circuit by mistake, it will automatically activate and restore output when connected to 5V charging).
