If you are traveling or staying outdoors for a long time and need technology, of course, a great power bank will always be with you. But you may not know what to look for when selecting your best power bank.

Guide to buying the best power bank

Define your application

Before buying the best power bank, you should pay attention to what products you buy to charge it. In fact, there are different power banks in the market, each of which is suitable for a specific application, which is briefly mentioned below:

Power banks for phones and tablets: These power banks are the ones that are found more than any other power bank in the market. These power banks usually have a voltage of 5 volts.

Parobank for laptops: To charge a laptop with a power bank, you can not use the usual power banks on the market, and you have to go to power banks with a voltage of 16 to 20 volts.

Smart Power Bank: This type of power bank is suitable for any device because it adjusts its voltage and current according to its battery needs.

Solar Power Bank: This power bank is suitable for people who care about the environment or spend a lot of time on trips such as mountaineering, etc. In fact, this power bank is charged using the sun, and in case you do not have access to city electricity to charge the power bank, it will be the best power bank.

Power bank capacity; Always choose a little more.

Once you have chosen the type of power bank you use, you should pay attention to the capacity of your devices. For example, if you want to charge a 3000 mAh phone with this power bank and you need to charge the phone for at least 2 days, you should go to the 10,000 mAh power bank to meet your needs. In fact, when buying the best power bank, you should pay attention to its capacity, which is displayed in milliampere-hours.

Of course, you should know that the capacity mentioned for power banks is its nominal capacity, and in fact, the actual capacity that the power bank gives you is less than what it says. Some power bank companies claim that their power banks have a real capacity of 90%, and this 10% is a waste of energy due to heat, etc., but in reality, we see that the real capacity is less than this and maybe Reach 70%.

The main reason for this discrepancy between the nominal capacity and the actual capacity is that the battery capacity in the power bank is measured at 3.5 volts. In comparison, the smartphone battery is charged at 5 volts.

In any case, when buying a power bank, first find the battery capacity of your device, then assess your needs. And in the next step, note that you will have access to practically 70% of the power bank capacity! Therefore, it is better to choose more than you need to be sure that you will never run out of charge in an emergency.

To calculate how many times you can charge your phone with one power bank, we have a simple example for you:

Suppose our phone has a 3000 mAh battery. Now you have a power bank with a capacity of 10,000 mAh with an efficiency of 70%. According to the following calculations, with this power bank, you can charge your phone 2.33 times, that is, two full charges and one charge of up to 30%.

Also, do not forget that to charge the laptop, you must go to the high capacities of the power banks because the 10,000 mAh power bank does not meet your needs at all.

The number of ports depends on you.

Another issue to consider when buying a power bank is the number of devices you plan to charge at the same time. In addition, if you have a shortage of sockets, you can solve this problem with a power bank. The power banks currently on the market have between 1 and 3 ports, and it depends on your needs to choose how many ports it is.

On the other hand, some power banks use the Lightning port. This port, which is especially for Apple devices, is one of the advantages and strengths of this group of power banks, but keep in mind that the existence of the Lightning port will increase the price of the power bank.

Weight and dimensions; The key point in choosing the best power bank

If you are a traveler or need to hold the power bank for a long time or carry it in your bag, pay attention to the size and weight of the power bank. The current power banks on the market weigh between 100 and less than 500 grams, but we usually encounter power banks in the channel of 200 to 380 grams.

However, if your needs require you to buy a power bank with a large number of ports and high capacity, you should know that its weight and size will be large and heavy in nature. You are the one who has to find the best power bank between your need for high capacity, more ports, and weight and dimensions.

LED lights make your work easier

If you want to know the status of the power bank, the amount of charge remaining and the percentage of its charge, etc., there are par banks that determine this operation with LED lights. Others are more advanced and give you more accurate information using a small screen.

The best power bank brand

Undoubtedly, choosing a power bank from famous and reputable brands that have passed the test for everyone will ease your mind. Of course, do not forget that paying attention to the brand factor in choosing the best power bank will increase its price for you.

Among the best brands of Parobank, we can mention Adata, Energizer, Anchor, and Xiaomi, etc.

safety tips; Use correctly

The last important point that we should mention in choosing the best power bank is using it. Power banks use the same batteries used in smartphones that are lithium-ion and lithium polymer. So do not forget that over time and with a certain number of charging and discharging times, the quality of the power bank is actually affecting.

Therefore, when you have access to electricity and sockets, it is preferable not to use the power bank so that you can enjoy its proper operation for a longer period of time.

Also, be careful not to miss the power bank, as impact and fall can cause chemicals to leak into the batteries and even cause a fire.
