Technology is advancing by leaps and bounds, especially in mobile telephony. Our telephones function almost like personal computers. We can use them to check our e-mail or the latest news. We can listen to music, make calls and share our photos and videos on social networks.
Their most problematic aspect is the battery. Rare is the cell phone that lasts a whole day without needing to charge it. Sometimes even less. Thanks to power banks, or portable batteries, we can now recharge the phone anywhere. Here is a selection of the five best power banks of 2022 to guide you if you consider buying one.
The most important thing
Before deciding which power bank to buy, the first step is to know what you will use it for. There are models of tiny size to carry in your pocket, practical for a charge or two. If you need to make more charges, or you are thinking of taking it on an excursion, you will need a model with more capacity.
Knowing which devices you plan to connect to your power bank is also essential. Any device that charges using a USB cable should be compatible with a portable battery. We are talking about cell phones, of course, but also tablets, sports cameras, or Bluetooth speakers.
Knowing how many devices you need to connect simultaneously will save you headaches. If you only need to connect one device at a time, it will be enough if it has a USB port. If you want to connect several devices simultaneously, you will need one port for each device. Make sure that the connections are suitable for your devices.

Nothing can be more annoying than running out of battery in your cell phone when you need it the most. Whether on a getaway in the middle of nature or a business trip doesn’t matter. Portable batteries are an excellent option for not missing that all-important call. Here is a list of the best power banks to help you decide.
What you should know about power banks
Mobile devices, especially phones, have become essential tools in our daily lives. However, their battery life is often insufficient. Having a good power bank can be very useful on many occasions. This section will tell you the most important things you should know before buying one.
What exactly is an external battery or Power Bank?
An external battery is an electronic device that allows you to recharge electronic devices without having to connect them to the mains. When you go on a trip, it is the ideal accessory for a cell phone, laptop, or tablet. They are light, compact, and easily transportable devices.
With it, you no longer have to worry about running out of battery in the middle of a work call. Nor will you have to worry about your phone turning off just when you’re waiting for an important message. Or about running out when you’re playing a game of your favorite video game.
How does a power bank work?
The most literal translation of power bank would be power bank. However, it is more common to use the term portable battery to refer to it. Its operation is effortless. First of all, the power bank needs to be charged.
When our device, for example, a cell phone, shows low energy levels, it is time to use the power bank. Instead of plugging it directly into the mains, we use the cable to connect it to our portable battery. This way, the power bank starts supplying energy to the device and will begin charging.
This way, the portable battery stores energy and supplies it to other devices.
How many charges can be made with a Power Bank?
A grave mistake is often made when calculating the number of recharges that can be made with an external battery. Many people think it can be obtained by dividing its capacity by that of the device to be charged. This results in them believing that they have been deceived about the battery’s capacity.
Unfortunately, no energy transfer process is 100% efficient. In the specific case of external batteries, their actual performance is around 60% or 70%. A formula calculates how many can be made with an external battery.
Number of charges = Capacity of the external battery (mAh) x Performance / Capacity of the battery of the device to be charged (mAh)
What care does a Power Bank require?
First, it is essential to keep it from high temperatures. Exposing it to very high temperatures can irreversibly damage it. Of course, as with most electronic equipment, it is essential to avoid getting wet. If it should accidentally fall into the water, you should not use it again.
Avoid placing one on top of the other when charging a device with an external battery. Doing so may increase the temperature of both, causing them to suffer damage due to overheating. Otherwise, it is advisable to use them with the appropriate chargers. Make sure they are compatible with your battery.
With which devices can a power bank be used?
The most common use of a portable battery is usually with cell phones. This is because the cell phone is a tool that almost everyone uses daily. Many people use the phone intensively and need to recharge it often. The problem arises when there is no power outlet nearby. The power bank is an ideal solution in these situations.
However, although this is the most widespread use, it is not the only one. Power banks can also be used can also use Power banks with other devices that charge similarly to cell phones. We are talking, for example, about tablets, Kindle, cameras, or GPS. Some models, such as the Nauvoo, can even charge laptops.
Many portable batteries have an intelligent design. Thanks to it, they detect the voltage of the connected device to charge it at the highest possible speed in a safe way. They also often include mechanisms to prevent overheating. It is essential to consult the instructions to check the compatibility of our devices with the power bank.
What is the mAh of a power bank?
The abbreviation mAh stands for milliampere-hour. The ampere is a measure of current. The milliampere is, therefore, one-thousandth of an ampere. Without getting too technical, the mAh of a power bank indicates the amount of energy it can store. This is an essential aspect.
The greater this amount of stored energy, the more power it will be able to supply water to the connected devices. In other words, the more times you will be able to charge your cell phone without having to recharge the power bank. Remember that the more devices you connect to the portable battery, the sooner it will discharge.
How to connect a power bank?
The most common way to connect a device to your power bank is via a USB cable. Some models include this cable in the same package. If this is not the case, you should not worry because the line can be purchased separately at a meager price. Secondly, because you probably already have one.
The cable you often use to connect to the power adapter will work for you. Keep in mind that not all phones and tablets have the same connections. You will need to use a suitable cable for your mobile device. It should be noted that the more USB ports the portable battery has, the more devices that can be charged can charge the more devices at the same time.
How do I charge a power bank?
For your power bank to work correctly, it must have been charged beforehand. Remember that the power bank functions as an external battery and, as such, needs to be recharged frequently.
The higher the charge level of your portable battery, the more charge it will be able to provide.
Most commonly, the power bank is charged via a USB cable. You should plug the cable into the micro USB port on the battery. The other end of the line must be connected to a plug through an adapter. For example, the same one you use to charge your cell phone. There may be differences between models, so it is essential to consult the instructions.
How does a solar power bank work?
The difference between a traditional power bank and a solar power bank is that the latter incorporates a photovoltaic panel. This is commonly called a solar panel and allows light to be transformed into electricity. Thus, placing the power bank in the sun will automatically start recharging its battery.
This system is ideal for excursions in nature or camping, where access to sockets is limited. However, it is essential to know that the charging time of the power bank using solar energy is very slow. On the other hand, most solar portable batteries can also be charged by connecting them to the mains.
What is mobile power?
A mobile power supply is a device that provides power to portable electronic units through a wired connection or stored charge. External power supply devices extend the usefulness of an electronic product beyond the limits of its internal battery.
Are power banks DC or AC?
The PowerBank™ stores electricity from solar and wind chargers (DC input), conventional generators, and the grid (AC input). As a reliable primary or backup power supply, the PowerBank™ is safe for indoor use, is non-toxic, and does not require ventilation or cooling.
Which power bank is safe?
Safety: Go for a power bank with a high-grade Lithium-Polymer battery. Safety is a significant concern when it comes to mobile devices. Many users charge their smartphones while sleeping, which could lead to problems. Low-quality power cells fitted inside some Power banks can explode due to overcharging.
How many mAh is a good power bank?
Anything from the 5000-to 2000 mAh in a power bank will work best for you, but you must remember you will likely not have multiple options for power included with a smaller device.
Are power banks safe for phones?
It is a good practice not to use your cell phone while it is getting charged via a power bank. Using the phone in a charging state may raise the internal temperature and harm battery life.
Can power banks explode?
According to our previous research, the main reason for power banks exploding is the imperfect circuit. It is in lousy welding (sometimes with contaminants). Or it does not have the proper courses insulated to prevent short circuits. It leads to overheating, then fires and explodes.
Do power banks destroy batteries?
A lousy quality power bank can damage your phone’s battery, as well as your phone’s charging port. It can also create some security risks. For example, overcharging a bad quality Lithium-ion power bank can cause the power bank to explode. Having the wrong voltage in your power bank will lead to problems.
What are the disadvantages of a power bank?
The disadvantages of a power bank:
Many power banks are heavy or costly. They must be charged as soon as their battery is low. If they are softer, they will drain faster. In some cases, they can also affect the battery of your phone.
How does a mobile power bank work?
A power bank’s built-in battery charges through an external power supply, such as a wall socket, then store the energy in chemical form. The battery sends electrical energy to the connected device via the output port when needed. The process consists of three parts: power absorbing, storing, and releasing.
Should I drain my power bank before charging?
But generally, it is suggested to charge the power bank first before using it. As the right thing to do, you should fully charge the power bank before using it for the first time, even if it has some charge once you take it out of the packaging.
How do I know if my power bank is fully charged?
Your power bank should start charging. If it has an indicator light, keep a close eye on it. Once it is fully charged, all the indicator lights will illuminate. Unplug the charger from the wall or your computer once all indicator lights are illuminated.
How long do power banks last?
between 3-4 years
The average lifespan of a power bank is usually between 3-4 years and will hold a charge for around 4-6 months on average, which will start a bit higher and experience a 2-5% loss in overall quality each month, depending on the original quality and use of the power bank.
Should my battery charger be flashing?
The slow flash should stop after a short while or after the temperature returns to a suitable range between 50°F and 86°F (10°C and 30°C). Fast flashing indicates a poor connection between the battery and charger or a problem with the battery pack.
What are the advantages and disadvantages of a solar power bank?
In short, the solar power bank is a good choice if you will be exposed to solar energy for a long time. For example, you can leave it in the sun all day during a long hike or camping trip. Taking advantage of random access to a power outlet to recharge the power bank is an idea to consider. Let’s see a table of advantages and disadvantages:
- It allows to charge it using the energy coming from sunlight.
- It is convenient for extended excursions or camping.
- Usually, it can also be charged by connecting it to the mains.
- It can be used as a traditional power bank.
- Some models are waterproof, dustproof, and shockproof.
- It takes longer to charge when using solar energy
- If there is not enough sunlight, it will be necessary to use electricity to charge it.
There is a wide variety of power bank models on the market. Therefore, it is normal to feel a little lost when buying one. To help you make the best decision, we have prepared this section. In it, you will find some of the factors to consider to get the best power bank for 2022.
The size of the power bank you decide to buy should depend on the use you will make of it. If you are planning to use it daily, you may need to be able to carry it around with you comfortably. A small portable battery would be ideal in this case. Of course, the number of charges they can provide is more limited.
If you are looking for a lot of charging, you will need a higher-capacity power bank. This usually means a slightly larger size. However, portable batteries on the market fit in your pocket and provide up to three charges. If you are looking for a higher number of tasks, you will probably have to go for a larger power bank.
This factor is closely related to the previous one. The Nauvoo model we cited earlier, for example, has a higher capacity than the portable Poweradd model. However, it is not as simple as making an equivalence between size and power. There are similar-sized portable batteries with different capacities.
The important thing is to look at the manufacturer’s specifications, specifically the milliampere-hours (mAh), which we discussed earlier. The higher this figure, the greater the number of charges it can provide. That is, it will have a higher capacity. It is important to note that it depends on the device you will charge to calculate the number of charges.
Number of ports
The number of ports on the power bank you choose is no small matter. We are referring to the number of connections it has that will allow you to connect more than one device simultaneously. If you only need to connect one device simultaneously, one USB port will be more than enough.
If you need to connect more than one device simultaneously, you will need the power bank to have more ports. For example, it is often necessary to charge the cell phone and tablet simultaneously. For this, you will need a USB connection for each device. Even portable batteries allow you to connect laptops via AC connections.
Did you know that there is a power bank with a capacity of 48,000 mAh?
The useful life of a power bank refers to the number of times we can use it since we bought it. It is also known as the life cycle. Most often, a portable battery has between 500 and 1000 cycles. This is the number of times we will be able to charge it and use it before it stops working.
Of course, this is an estimated number and varies greatly depending on each model. It also depends on our use of the power bank and external factors such as temperature.
It is common in all batteries that with the passage of time and with its use decreases its charging capacity. It is important to be informed about this aspect before buying one.
Type of user
To get the best power bank about quality/price, we must first ask ourselves what use we will give it. We must know, first of all, how many devices we will need to charge at the same time. If we only want to set up our cell phone, a portable battery with a single port will be enough.
If, on the contrary, we need to charge more devices at the same time, we will need more ports. We must also ask ourselves how we are going to transport it. Do you want to carry it in your pocket? In your briefcase? In a backpack? Depending on this, the size of your power bank may be one or the other. Finally, consider whether you need it for more sporadic or everyday use.
|If I want to||I must buy|
|A battery for everyday use that you can carry with you at all times||A power bank with a smaller and more compact size|
|Use it as a flashlight||A power bank that includes this feature, usually through LED light.|
|Charging with sunlight energy||A solar power bank|
|A battery that allows me to set my laptop||A power bank with an AC port|
Recharging time of the external battery
The recharge time depends on the external battery’s capacity (mAh) and the intensity of the input current (mA). We advise you to check the maximum input current (Input) that the battery can admit, as this will limit the recharge speed.
In general, these magnitudes must appear in the specifications of the external battery. They should be indicated in the user’s manual.
In the case that the manufacturer does not specify them, a formula that can allow you to calculate the charging time is the following: Charging time (h) = Capacity (mAh) / Input current (mA).
The intelligent charging system allows the battery to identify the amperage of the connected device and optimize the charging process. Note that not all external batteries incorporate this system. In any case, more and more brands are manufacturing models that include it.
When buying an external battery, you should also consider some extra options. Interestingly, it has more than one USB port. This will allow you to charge more than one device simultaneously. Other extras are USB cables, an instruction manual, and a protective case.
In general, external battery manufacturers do not sell them with a charger. You can consider the fact that it is included as a plus when deciding on your purchase. The same could be said for products that offer extras such as backpacks, instruction books, or USB cables.
A cell phone is an indispensable tool in our daily lives. Due to its intensive use, the battery often does not last as long as we would like. The power bank is presented as an ideal solution for these cases. It is also a very versatile instrument since it can charge various devices.
Before choosing your portable battery, you must decide which area you will use it. Different options depend on whether you want it, for example, as an everyday work tool. If you prefer it for long trips, excursions or camping, you should opt for other models. In any case, a power bank is always a convenient accessory.
