How to choose the right micro usb cable

Micro USB connectors are the most commonly used in consumer products such as smart phones, Bluetooth speakers, power banks, etc. And they all require a micro USB to standard USB cable which can affect the overall performance of our device

For example, It can affect the charging speed of our phone or maybe even the connection stability. There are a few factors to pay attention when buying a micro USB cable and the comparison between a retailer and an aftermarket cable:

1.Wire Gauge: As the wire gauge goes down in numbers, the more thickness therefore more amperage the wire can handle.
Always keep an eye on the thickness of the cable as it can have severe effects on energy loss which results in slow charging speeds and the chance that the cable will melt. I’ve personally faced this issue with Samsung’s retail cables.
This problem can even destroy the micro USB connector on the device and make it unusable without a repair.

2.Isolation: Then Isolation and heftiness of the cable is a benefit for its life and charging speed.
The isolation can help with preventing EMI (Electro Magnetic Interference) which can bother you with near wireless systems like cell or WI-FI reception.
An example of a good micro USB cable is the one kind that Anker and Usams make. Anker includes pictures which show the isolation and heftiness of the cable:

3.Pin Count: Every USB cable has 2 power pins and 2 data pins; Most micro USB cables have 4 pins like standard USB but there should be a 5th pin which represents the ID pin.
What this pin does it to tell the power source such as an AC adaptor or a power bank how much amperage and voltage it needs for proper charging quality. The absence of this pin might occur disconnections while the phone(source) is connected to a computer and don’t interact properly.
This interference can also impact data transfer speeds.

An important tip: A cable without these factors, can prevent fast charging in many phones.

Proof for charging performance impact

I know that there might be YouTube videos or other articles which might falsify the above 3 factors; so I provided proof for this.

This test was done on a Samsung Galaxy Note 5 and a Samsung charger with the 4pin retailer cable that comes with it and the other cable is a 5pin isolated cable.
