Today there are many types of iPhone charger cords in the market. To attract consumers, some businesses have promoted their products with charging speed, low cost even better than genuine Apple products. However, the truth behind these adverts, is which Lightning cables are the same and the charging speed is more than just lost because of the charger? Let's operate two iPhone charger cables, one genuine for about $ 20 and a cheap product with the same design, but the price is only 1.5 USD (about 34,000 VND).
On the left is the low price iPhone cable, the right is genuine.
First, with cheap cable, users cannot ask for it to be contained in the box. This product is usually wrapped by a bubble bag on the outside.
The softness of the two cables is also different. This picture may describe somewhat of that state. On the left is a cheap, weak and almost cordless wire when it falls down. And on the right is a genuine cord, still soft enough but no less sturdy.
From the outside it is easy to see that the plug is not completely perpendicular to the wire but has a certain tilt.
In the middle of the cable is usually held with metal core plastic wire. But when disassembled, cheap wires will be left with marks that can be seen by the naked eye due to being squeezed by this type of protection wire.
When placing these two cables side by side, from the plastic material and the inclination of the plug wire, there is also a huge difference. The top is genuine, the bottom is the cheap cable.
As mentioned above, many merchants tend to promote their products better than genuine ones, through faster charging. However, this is difficult to distinguish if the user is going to buy, or when using it during overnight plug-in. Because whether it is fast or slow, after many hours charging the device will be full of batteries regardless of the type of wire.
Therefore, it is best to compare the charging speed when the device has reported a low battery, especially while charging and playing the game.
The scenario used is to start charging iPhone X when the battery is at 20%. Then just play the game while charging until the time is over 30 minutes. The final test results show that after 30 minutes of playing and charging with cheap charging cable, the battery remains 18%. As for genuine charger cables, the battery is still 9%.
So is a low-cost cable faster than Apple's genuine cable?
On the left is the device being charged with a cheap cable, the right is a genuine Apple cable.
In fact, the problem is not the battery charging speed. The chart below records the voltage and power of two charging cords during the test. On the left is a graph of cheap charging cables, which can be described by two "terrible" words. Meanwhile, the right graph of the genuine iPhone cable shows that the smooth and temporary curves can be called "smooth".
The chart also shows that the charging capacity of cheap cable is quite high in the first few minutes after plugging in the device, at about 9W. After about 8 minutes, it starts to fluctuate strongly, sometimes decreasing directly from 9W to 2.8 W and cannot stabilize again. This is particularly serious damage to the battery in the user's iPhone.
On the left is a graph of cheap cable, on the right is a good cable graph of Apple.
Next, we will "operate" these two iPhone charging cables to see the texture and materials inside.
First with cheap cable, when removing the outer shell will reveal 4 small wires with copper core. Overall copper wire seems very good. But after seeing inside the genuine Apple cable, you might think again.
The wires inside the genuine Apple cable are covered with a kin woven mesh and tin foil. They not only improve the overall toughness of the wire, but can also protect the cord from external interference from physical collisions, or curiosity of the device that the user wants to fix themselves.
When disassembling the outer plastic layer the Lightning plug can also feel the difference between the two products. In cheap cables, the rubber material is similar to that of wire, which can be easily removed by scissors. In good cable, this hard plastic layer is difficult to separate. In the picture are the two front faces of the Lightning head of the cheap cable.
. After stripping, the welding chips and solder joints are also clearly displayed. On low-cost cables are usually two chips with "3401" code and "HX10N" chip (black). With genuine Apple accessories, they need to be MFi certified to allow iOS devices to connect. Two cheap wire chips are designed to fool this certification system. Meanwhile, in good cable, the entire circuit board is protected by a metal shell and it is very difficult to contact the inside.
The USB port is similar. Low-cost cables are connected via black plastic, while the cable side is sturdy, neat and neat.
Here, it is not too difficult for users to distinguish and compare the differences of two genuine cables and cheap products. Of course, cheap cables can still be used, but it does not guarantee durability or can damage the iPhone's battery, not to mention the occurrence of short-circuiting conditions.
