Buying Guide - How To Choose 5 Best Power Banks?

As its name suggests, a Power Bank, also called a portable charger, is used to charge your electronic devices, including mobile phones. As a result of the many models available on the market, many people are unsure how to select the best power banks for 2021. Let our buying guide help you. 

The criteria to take into account before choosing your power bank

 – Storage capacity

The storage space of a Power bank is indicated in mAh (milliampere/hour). It is advisable to choose a high storage capacity to benefit from a more powerful battery. According to the opinions and advice of many users, it still favours models of 10,000 mAh minimum, knowing that a storm of this performance is capable of supporting 3 iPhone recharges. It is also capable of charging a tablet at high speed. 

The choice of storage space depends mainly on your daily needs. Before buying your device, ensure that its storage capacity exceeds the users’ needs, i.e. 1.5 x your daily need. 

However, be aware that smartphones with large dimensions require an external battery with a capacity of at least 3000 mAh to ensure their full recharge. As for the shelves, the adapted degree varies according to their size. The higher the tablet capacity, the more power it requires. The Galaxy Note 10.1, for example, needs 8,200 mAh while the iPad 3 and 4 require 11,400 mAh. 

 – The transfer capacity

Increases in the charging rate are proportional to increases in the intensity of the current provided by the external battery. For models with multiple outputs, the total transfer value is the total of the respective values ​​of the output ports. 

For information, the charging time required for a smartphone is at least 1 hour 30 minutes if it is a high power battery. The charging time can reach 2h30 if the power of the power bank is lower. 

Recently, other models with USB-C connectors have been developed. USB-C is a more improved version of the USB cable. Its edges are thinner and more rounded. Compared to previous models, its transfer speed is faster. Indeed, it can display a flow of up to 4 A and 20V

 – The different formats

The format of a power bank can differ from one model to another. For example, rectangular shapes, rounded shapes, and models with ultra-thin edges are all examples of what we can find. These are widely regarded as having the best design available on the Canadian market.

 – The display system

Unlike conventional models, the majority of current external batteries use a more advanced display system. The gauge is now displayed through an LED screen. It is easier to track the condition of the storm. Other models contain additional functions such as time display, current date, time, etc. 

 – The different kinds of external batteries

Knowing about the different types of external batteries can also help you if you are wondering where to buy a new power bank. We can classify external batteries into 3 categories: standard models, fast charging models, and solar models.

Standard external batteries are known to be the easiest to transport. They are also appreciated for their ability to provide better autonomy. However, you should know that this type of power bank is less efficient when quickly charging a device with a high voltage. Therefore, it is not recommended for users who are often in a hurry. 

Fast-charging external batteries use charging technology that allows connected devices to reach 75% charge in just 5 minutes. But this has yet to be proven. However, the charging speed may not be tolerated by a low-voltage device as it may interfere with its operation. 

– Solar external batteries 

As external solar batteries work by drawing their energy through sunlight, they usually incorporate photovoltaic panels. These help the battery to better capture the sun’s rays. External solar batteries do not necessarily need a power source; they are very convenient for travel, camping, hiking, etc. 

After choosing your external battery, do not forget to go through a price comparator to quickly find the model, the price of which corresponds to your budget capacity.
