USB charging module: DC-DC step-down converter - 6V ~ 24V 12V to 5V 3A

DC-DC USB Buck Converter / Charging Module

• Max output current 3A, long-term use 2.1A, sufficient usage
• New design, 3 solid-state ceramic capacitors (MCC), safer and less ripple
• Synchronous rectification, High efficiency, 6.5V to 5V 0.7A can reach up to 97.5%, 12V to 5V 1A can reach up to 94%
• Flat copper inductor, improves conversion efficiency;
• With output overvoltage protection. There is a 1.5A fuse, output 5V has a 300W TVS tube to protect your USB device
• Using the latest USB identification circuit, perfectly compatible with IPHONE, most Android phones, etc.
• High quality USB port
• Output voltage indicator (RED)
• Small size, 26.4 (L) * 15 (W) * 7.4 (H) mm
• Input with reverse polarity protection diode, will not be damaged if the input is connected incorrectly
• Ultra-low static current, only 0.85 mA. No need to add a switch when connected to the car battery, can be connected to a car lighter cable or ACC power cable
