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 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 lighter cable or ACC power supply cable
