Warm prompt: Dear buyer, Our nsportation services Economic category logistics (SunYou Economic Air Mail ,China Post Ordinary Small Packet Plus ) can be ced only befor it arrive your country,please choose Standard category logistics if you want a full cking info.Pre Release:1: The new United States ed s, definitely not homemade s, disaemble .2: The maximum output current of 3A, the long-running 2.1A, sufficient margin.3: The new design, circuit design does not require electrolytic s and tantalum s (electrolytic life is short, there is a risk of explosion tantalum s). Now with the of high-end large-size solid ceramic circuit (MCC) 3Very low rple, 12V switch 5V 3A only about 10 mV rple many peers have reached 500 mV or greater, the device will ca an invisible injury, severe can ca fault or damage.4: The new program s synchronous rectification circuit conversion efficiency is very high, in turn 5V 0.7A 6.5V when efficiency up to 97.5%, 12V turn 5V 1A when it reached 94%, unlike some peers only 60-70% efficiency . (Efficiency test removed the input re polarity protection and f drop).5: Using flat copper inductors, maximize conversion efficiency. Reduce heat.6: The whole network first with output overvoltage protection, input f has 1.5A, 5V output of 300W TVS has done a preure clamp protection, protect USB devices.7: Using the latest USB identification circuit.8: Short head gilded boundle USB, long service life, not ordinary USB interface can be compared.9: Output voltage indicator (red)10: Ul-small size, 26.4 (L) * 15 (W) * 7.4 (H) mm, the smallest of the whole network.11: inputs with re polarity protection , the positive and negative input will not re damage (We d the efficiency of ignoring the input and f drop)12: ul-low quiescent current, 0.85 mA quiescent current. Connected to the car battery without adding switches can be connected in a arette line, or ACC power line cord.
