Unlike old cell phones that used to take a long time to charge, gadgets like cell phones and tablets need to be recharged at shorter intervals due to their larger screens and heavy processing. Powerbank is a gadget that allows us to charge our phones and tablets outside the room and on the go. In this article from the Foner website, we will review the best power bank models up to 1 Million Tomans.

Features of a good power bank to buy

Before introducing different models and brands of power banks up to 1 million tomans, it is best that we get to know the main features of power banks, also known as mobile phone chargers in Persian, so that we can choose the option we want with full confidence. Power bank cannot be rated based on one good or bad feature. Power banks have different features and facilities that we need to know enough about and know the features and facilities that are suitable for us.

An advantage can be seen as an advantage for one person, while it can be seen as a weakness for another. For example, a person who travels by car frequently will likely look for a power bank with high capacity and large volume. While another person uses the power bank only while walking to cover the distance from home to his place of work and cannot carry a heavy and large power bank with him.

power bank capacity

The capacity of the power bank is determined by the unit mAh (mAh). This number is how much charge the power bank can transfer to your devices with each full charge. For example, if you have a 10000mAh power bank and your mobile phone battery is 3000mAh, it can fully charge the phone about 3 times.

Power banks usually have a capacity between 3 and 20,000 mAh, which increases in size as the capacity increases. There are battery cells inside the power bank, the number of which is determined based on the capacity of the power bank.

input and output ports

When buying a power bank, be sure to pay attention to the input ports (charging port) and your mobile phone so that they are compatible with each other. Although conversion cables can be used, the similarity of the ports makes it unnecessary to purchase a conversion. Newer power banks often come with a Type C charging port, which is compatible with newer phones and tablets, while older power banks often have a USB-A charging socket. This port is compatible with older phones.

The USB output port is also very diverse. Some power banks only have one output port, while higher capacity models will give you two. In addition, on models with two separate ports, one port will usually have a higher output power than the regular port, which is used for fast charging.

fast charging

Most of today’s smartphones and tablets support fast charging technology, which is why power bank manufacturers also include this issue in their products.

charging indicator

Most medium and high capacity power banks have a light or display that indicates how much charge is left in the device so you can know when you need to charge the power bank.

wireless charging

Given that some new phones and tablets support wireless charging technology, power bank manufacturers have released a number of their models with this capability; So, if your device supports this feature and you want to use it, you can choose a power bank that will allow you to charge wirelessly. Of course, this technology is currently very expensive and power banks produced with this technology have a noticeable price difference with normal power banks.

What points should I pay attention to when purchasing a power bank?

The most important part of a power bank is the battery cells used in its production. Reputable manufacturers use first-class battery cells, while unknown and unreliable manufacturers use cheap, low-quality cells to reduce the final price of their products.

A cheap and unreliable power bank may have a nominal capacity of 10,000mAh, while its actual capacity is not even 5,000! Poor quality cells have a lower yield capacity than listed. In addition, underground manufacturers usually put unrealistic numbers on a power bank.

For example, the total number of cells used in a power bank may be 4,000 mAh, but the number 10,000 mAh is written on it. In other words, their nominal capacity is more than twice the actual capacity of the battery cells.

In addition to the use of low quality battery cells, other cases have also been observed in non-original power banks, which are considered a form of fraud. For example, in some power banks, instead of a battery cell, a cylinder containing sand is replaced to make the power bank look heavy.

This question might come to your mind, how do you determine the type of battery cells used in a power bank? In response, it must be said that there is almost no way out, and you should only use brands that are trusted and have passed the test in recent years.
