Buying Guide – How To Choose A Good Power Bank?
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.

frequently asked Questions
Q1: How to charge a power bank?
A power bank charges like a classic smartphone. You need to connect it to a specific charger. It is then connected to a micro USB input port or a USB C to be connected to a power source. Most of the models recently offered on the market are compatible with Power Delivery or the fast charging protocol. The external batteries can be charged with chargers having a voltage of 5 V. You can also connect them with the fast recharging, which displays a higher voltage varying between 9 0 12 V.
To charge a power bank via a computer, you must use the USB or micro USB cable supplied in the delivery. Just connect the USB plug to a USB port on your computer and plug the micro USB output into the battery.
Usually, the charge indicator will display orange or red colour depending on the model while charging. The colour turns green or blue when the battery is charged.
Q2: What does mAh mean for a power bank?
The mAh index stands for milliampere-hour. It is a charging unit that is often used to estimate the autonomy of a smartphone or other more or less powerful devices. It gives you a more precise value for the amount of charge possible with an external battery. On the other hand, this unit does not allow the evaluation of the independence of an external battery on its own. You also have to consider the number of volts and then calculate the watt-hours.
Q3: How to use a power bank for the first time?
The first thing to do before using a power bank for the first time is to charge it fully. Once it reaches its maximum charge, you just have to connect it with the other devices to set them in turn.
Q4: What is a power bank?
A power bank can have external batteries, portable chargers, portable batteries, backup batteries, USB batteries, etc. This device makes it possible to bring current to recharge devices when there is no access to an electrical outlet. A power bank comes in the form of a box. When charging, it stores energy to transfer it to other devices (smartphones, tablets, etc.) if necessary. The energy stored by the power bank is returned via a USB cable.
Q5: How does a power bank work?
A power bank or external battery consists of a plate of electronic components. It works with a lithium-ion battery. It must have a power of 18,650 mAh and a voltage of 3.7 V to support a portable charger. The device to be charged must be connected to the power bank via a USB port. The connection can only be made when the battery recognizes the device in question. Thanks to PCB, there is no risk that your power bank will overload.
