What is Powerbank, what does it do

Powerbank is a small size charger that allows you to charge a lot of rechargeable electronic devices, especially for smartphones and tablets, for example mp3 players, cameras, and so on.

There is not much difference between Powerbank and the battery behind the cell phone or tablet. As a result, both batteries. Powerbank's task is to add additional power to your mobile device, which has a reduced charge with the outputs on it.

Powerbank models are today's most popular accessories. Each company has different capacities, tens or even hundreds of different powerbank options are available. So what should be paid attention? Here we go slowly to the real subject of our article.

What is Powerbank? What should we pay attention to?

We are with the powerbank guide, which is the most practical and realistic solution to the problem of charging from 7 to 70 to everyone's common problem. What is Powerbank? What should we pay attention to when purchasing Powerbank?

At the beginning of our article, if you wish, we will discuss the source of the problem.

What is Powerbank? Why is it so important?

Not so long, 10 - 15 years back, there was no wireless network support on portable computers, so it was just coming out. We even used portable computers in a cable-dependent manner.

The technology has developed and improved in the last 15 years. We live with realities far beyond what is imagined. There are still areas where such advanced technology still does not offer adequate solutions. At the beginning, battery technologies are coming.

As long as the battery technologies are not well developed, if we are using our mobile devices intensively, we need to get accustomed to the powerbank reality to charge it outside.

In this article, we shared with you in the most detailed way what you should pay attention to when purchasing powerbank. You can also look at the latest powerbank models from the link and purchase them.

The bigger, the better!

The battery technology is still moving in a very primitive way, in other words the right proportion. The higher the mAh value of the battery, the more battery life.

The high mAh value of the battery means more space, weight and thickness.

The biggest obstacle in front of electric cars, unmanned aerial vehicles, today's battery technologies. Because in order to increase the range of cars, it is necessary to make the batteries much larger and heavier, this time the fuel consumption of the vehicle is increasing more and a vicious circle is produced. This is the case with the phones.

Let's get to know the batteries.

We always use the abbreviation mAh. So what is this mAh?

This term, which is used as a millamper / hour, indicates how many miles of amperage can be stored per hour and can transmit to the device. But it's worth reminding. Amperage - the hour is not an energy unit.

1 Ampere = 1000 mAh

Take good care of the chargers you use. Typically 5v 1A output power writes. 5V is fixed on USB outputs. But the amperage value is variable.

A charger with 1A output power charges a 2000 mAh battery in about 2 hours.

In fact, we know that our fast charger is the charger, which has a higher output amperage. A charger with 5v 2A output charges the 2000 mAh battery in 1 hour. This way, you charge 2 times faster than the 1A charger.

Of course, higher-speed charging technologies are also available. Usually the current is increased with special coils and the battery is shaken to provide faster charging.

Losses should not be forgotten

You received a powerbank of 10,000 mAh, ie an external battery. The battery of the charger is 2000 mAh. With a straight logic of 10,000 mAh powerbank, you think you will charge the 2000 mAh battery 5 times, but there are losses.
Nowadays, battery technology is still very affected by the heat. Powerbank expects the region to be used, the charging cable used, the poor quality of the cables will increase the loss, especially because it will show more resistance. With time-dependent condition decreases and environmental factors, the 10,000 mAh powerbank will be able to charge a minimum of 2000 mAh of 4 to 4.5 times of full capacity.
