**The right way to choose and use charger efficiently –** The **battery** is the most important thing if we consider all parts of our **smartphone**. Without a battery, our smartphone becomes useless as we can’t use it anymore. So, for battery, we use a charger which charges the smartphone’s battery so that it can be reusable.

But if we take a look at a charger, then there are many types of chargers and all chargers have their own charging compatibility and speed. On our charger, we can normally see some text written on the back or front side, but we never saw them carefully and know about it deeply. Do you know that the physical overview of a charger defines all the things about it.

So, for you, today I am providing you the Right way to choose and use charger efficiently.

## Right way to choose and use charger efficiently

So friends, let’s get started with the Right way to choose and use charger efficiently.

Basically, if we take a deep look at the text written on the charger, they are trying to define only one thing I.E. “output current” which is the main objective of any charger.

Through output current, we can determine that how much current will charger generate and flow towards our mobile or laptop and how much time our smartphone take to charge fully.

- The first term on which we have to focus is “ampere” which is defined as “A” on our charger. Ampere will define that how much battery capacity is converted and sent to your smartphone in an hour. Means if your charger has written 2A, that means it will charge a 2000mAh battery in an hour (mAh= milliAmpere/ hour)
- The second term on which we have to focus is that “voltage” which is termed as “V” on the charger. Voltage defines that what is the receiving current capacity of our charger, means how much current our charger can grab when plugged in at a time. In most of the cases, we can see that charger having the input voltage of 5A.
- If we take a look at the battery of our smartphone, then we should keep only one thing in mind I. E. “1000 mAh= 1A”. So, if our smartphone Slattery is 3000mah then it is 3A.

### Let’s get to some calculation

**Suppose if I am using Xiaomi redmi note 4 (which has 4050 mAh battery and a 5V 2A charger in the box), then how much time it will take to charge? **

As I said above if we have 2A charger and 2000mAh battery, then it will take one hour to charge, so, if we follow the same equation, then we can conclude that our xiaomi redmi note 4 can charge from 0 to 100% in 4050/2000 mAh= 4.05/2 A = 2 hours 1 minute and 15 seconds Flat.

**I have a laptop which has 8800 mAh battery and the charger equi****pped with it has a power of 5V 2.5 A, then how much time it will take to charge my laptop fully?**

Laptop has a battery capacity of 8800mAh, charger output current is 2.5 A, So, here the equation will be:-

8800/1000= 8.8 A

8.8A/2.5 A= 3 hours and 30 minutes (approx.)

But your laptop will be fully charged in about 4 hours because laptop consumes battery even if it is charging. Hope you will get the best answer.

### Here, we came to an end of Right way to choose and use charger efficiently

So friend, above is the Right way to choose and use charger efficiently. Hope you will understand that how the charger works according to its details written on it. The inner mechanism is all about converting current into battery capacity, but the outer side of the charger defines that what is the real power of a charger.
