Cheap High efficiency smart phone USB car charger

This is the first time I have purchased a very cheap USB smart phone charger for car made in china with high efficiency. The device is input voltage is within 12 volt to 24 volt from the battery car charger and output 5 volt @ 2000 mA (2 Amp) of current. I have tested no doubt about that it can charge Samsung Galaxy A5 smartphone within a considerable time period. It's only cost RM7 but it works superbly. I would say this device outperformed the original Samsung home charger plug with output rated at 5 volt @ 1500 mA (1.5 Amp).



It doesn't take a long time to charge the phone from 15% to full charge 100% around 45 minutes to 1 hour period. I am very impressed and not like the rest i have purchased before which charge long hours without any increment to the charges.

The only drawback when it was opened to check the circuit components - the main IC which is used to step down the current has no name or component code on it :O. What is it?!! lol
