DC Mô Đun Hạ Áp 9v 12v 24v Xuống 5v 3a Cho Xe Hơi

[sun] 9V 12V 24V to 5V 3A CAR USB Charger Module DC Buck step down Converter [my]
Features:
Description:
- The max output current 3A, long time use 2.1A, enough use
- New design, 3 solid state ceramic capacitors(MCC), more safe and low ripple
- Synchronous rectification, High efficiency, 6.5V to 5V 0.7A can up to 97.5%, 12V to 5V 1A can up to 94%
- Flat copper inductor, improve conversion efficiency
- With output overvoltage protection. There is 1.5A fuse, output 5V have 300W TVS tube protect your USB device
- Using the latest USB identification circuit, perfectly compatible with IPHONE, the most of Android phones, IPAD etc
- High quality USB port
- Output voltage indicator (RED)
- Input with reverse polarity protection diode, will not damage when input connect incorrect
- Ultra-low static current, 0.85 mA only. Do not need to add swith when connected to the car battery, can be connected to car cigarette lighter cable or ACC power supply cable
