Key Ideas on how to Identify a Fast Charging Charger/Cable for Phone


How often have you bought a phone charger only to find it is not up to your desire? It is such a weird situation. Fortunately, in this century we have fast charging chargers. They are capable of charging 100% even within half an hour. Enabling you to cope with rush hours or a busy day when you need your phone most.

In this article, we will be looking at;

  1. How to identify a fast charger
  2. What is fast charging?
  3. How to identify a fast charging phone cable
  4. Whether fast charging depends on a USB cable or adapter?
  5. Verdict on charging the phone often in a day

So, read through the article to be informed on the best choice of charger you need.

How to Identify a Fast Charger

We have three main ways of identifying a fast charger. They include:

1. Read the label on the charger

The label tells you more about power output. Before you buy, confirm whether the rating is high. For example, one whose format is 4V---1A or any value below that is definitely a slower charger. But if you find one whose format is 5v---1.2A or value above that, then you have a faster charger.

2. Install the Ampere Application on Your Phone

The application will help to reveal the output current the charger is producing. The fast charger should produce a current of 2 Amperes and above.

3. Google search specifications of your phone

This will help you to get recommendations on the type of charger your device requires. Whether your phone’s specifications are for a fast or slow charger. Note: If a device battery requires a low charge, using a fast charger can lower the battery's life.

What is Fast-Charging?

It simply refers to a charging rate that is above ordinary charging. The process is achieved by the manufacturer by varying the power output. In this case, the voltage or the current (amperes) is varied. So a fast charger has the highest power rating.

For instance, the one rated 5 volts and 2 amperes (10watts) is faster than the one rated 4 volts and 1.5 amperes (6 watts).

How to Identify a First Charging Cable

Well, what matters most on the choice is the material, length, and thickness of the conductor (wire) in the cable.

Material: Cables make of aluminium or copper have a high rate of charging due to high conductivity.

Thickness: The thicker the conductor, the higher the rate of current flow. On the contrary, a thin wire has more resistance and therefore will deliver a lower current.

Length: The longer the cable the lower rate of power flow, this means charging will be low if a long cable is used.

So when buying a phone cable go for one that is thick, short, and make of good conductor material.

Does Fast Charging Depend on the Cable or Charger?

The good quality of the two is directly proportional to fast charging. However, 70% of the cable and 30% of the cable depend on fast charging.

Let’s see how the two affect the charging:


  • The higher the power output, the fast rate of charging. The opposite is also true.
  • For instance, one that on the label reads 9V---2A (18 watts) charges faster than one that reads 5V---1.5A (7.5 watts)


  • Also known as the USB cable, it is the medium between the charger and the device.
  • The good conductivity of the wires used is a key factor. Cables made of Copper or Aluminium work best. Try an experiment and you will prove me right.
  • The thickness of the wires is also a crucial part. The thicker the wires, the faster the charging output. Amazingly, a shorter cable works best compared to a longer one.

Is it Bad to Charge My Phone More Often in a Day?

Perhaps, you are worried about your battery’s life when you are consistently working with your phone, the percentage of charge keeps dropping. In this case, you have no option but to recharge it.

From now onwards, you don’t need to worry about recharging often. Why?

Smartphone batteries; commonly known as Lithium polymer batteries have a certain number of charge cycles. Normal batteries have about 1000 full charge and discharge cycles. This means when your phone is at any level below 100%, the cycles are not complete.

So, never mind the number of times you charge. Moreover, current smartphones are designed such that, when the battery is full, the flow of power is cut instantly. This ensures the battery is not damaged, as well the phone does not overheat.

Worth of note: Never! Let your battery discharge to 0%. According to scientists, the action will degrade the battery.


You now have all that it takes to make the best choice when buying a fast charger. However, take note of the negative effects associated with high current. High current from fast chargers may lead to heating effects

High heat may destroy the cable or make the device become extremely hot. So make the verdict wisely whenever considering charging options.
