It is original. The model number of the power adapter (charging plug) of the National Bank version of iPhone is A1443, both manufactured by Lite-On Technology Co., Ltd.

The authenticity of Apple chargers can be identified as follows:

1) First look at the appearance. In fact, careful students can immediately tell which one is a fake charger. The overall level of craftsmanship is easy to compare, but it is difficult to identify it immediately when you only hold a copycat charger. Non-original chargers have a green dot, which is one of the genuine and safety marks. Those with green dots are said to be genuine. Note that this is not the case. In fact, most knockoffs have green dots, but they are still inferior. Don’t be convinced by the seller’s green dots. Continue to identify the products below.

2) Pay attention to the text in the photos. Generally, electrical appliances have inscriptions to indicate the place of origin, model, performance, safety indicators, parameters, etc. Counterfeit chargers will never do typesetting carefully and just roughly imitate a layout. Then the printing is rough, the edges of the writing are rough and ink leaks, and the fonts are not clear and beautiful. The origin is mostly labeled as Japan, Vietnam, Malaysia, etc.

3) For the identification of USB ports, the accuracy of counterfeit injection molds is very low. In order to prevent misalignment of insertion and extraction, the size is often larger than normal. The plastic tongue core is rough and thick, the socket inside is misaligned with the shell, and the metal pieces inside are dull and different in size. The genuine one shows precise craftsmanship, clean and tidy, and the size is exactly the same.

4) Plug in the USB head and take a look again. It turns out that the original one can still be plugged in and out easily, sometimes a little tight. The plug and the shell are basically tightly fitted and inserted very deeply. The fake one is loose and can only be inserted more than half way, and it is a little crooked when inserted.

5) Let’s take a look at the details of the USB plug. Apple’s USB plug has a matte finish and is very soft, uniform and delicate, while the copycat version has a rough matte effect. The logo of the USB is an important point. The genuine ones have uniform color and clear edges, while the knock-off ones are round or square, with ink leaking around the edges. The color of the thread is also different. The genuine thread is not pure white but light gray, with elastic texture and moderate hardness.

6) Take a closer look inside the USB plug. On the left is a copycat. The metal edge is furry, the tongue core is thick and furry, and the metal piece inside is dim and obscure. On the contrary, the original version on the right has delicate metal edges, moderate tongue thickness and sharp edges, and internal metal rows, shining with light gold.

7) Differences in details and shapes can also be seen in the metal craftsmanship of the plugs.

8) As for the seams of the entire shell, the genuine charger has decorative, fine and neat gaps, while the counterfeit charger is rough and has many burrs. The main reason is that there is no such gap, because the counterfeit ones will not be so detailed. .
