Portable batteries, not all are the same: what you need to know to choose the right battery for your use


The presence of an external battery guarantees us the ability to charge our smartphone, tablet or other type of device when we need it, regardless of the electrical network.

We’re talking about devices that are also evolving and today offer a lot of features that we didn’t have many years ago and that can be very interesting now that encourage charging.

But it’s not just that, we also have different types of external batteries that offer solutions for different situations that we can dive into. This means that the versatility offered by these devices is much higher today, and the more time passes, the more improvements they will include.

To get the most out of this, it is best to know all the types of existing batteries that they offer us, and from this to be able to decide which one is best for our circumstances and our financial possibilities.

Types of external batteries

As usual, there are different types of external batteries to try to fulfill all the circumstances in which we may need a device of this type to charge a smartphone, tablet or any other device compatible with this charging system.

We can include external batteries in these types:

  • Ordinary: these are all those batteries that do not have any feature. That is, with more or less charge, with a rectangular shape, a charge indicator, which usually have a USB to recharge it and another one or two to connect our devices such as smartphones or tablets, among other things.

  • Pocket size: These are the ones that are designed to be carried from one place to another and not only weigh as little as possible, but also take up little space. We can find models with a length of about 10 cm, weighing even less than 200 grams.

  • Ultra thin: pocket batteries, but even more compact. We can talk about very flat models that can be between 8-9 mm, weigh about 100 grams and can charge a normal smartphone battery up to about 60%.

EUARY power bank

  • Multiboot: They have a concept that is dominated by the number of devices we can connect. There may be cases that reach a capacity of more than 30,000 mAh, which allows you to connect 4, 5 or 6 devices at the same time.


  • Wireless connection: These types of batteries are very convenient since we will not need to connect any cable, although most of them offer us this option if we need to charge more than one device. To take advantage of wireless charging, we just have to put a smartphone compatible with this system on top of the battery. Thus, the mobile terminal will start charging.

  • Sunny: They are ideal if we go hiking or somewhere where there is no electricity supply, since with sunlight we can charge it and thus have enough energy to connect our smartphone.

Feob Solar Charger

  • With fast charging: It’s not really a type of battery, but we might have that kind of power in a few of the models we’ve just seen. Thanks to fast charging, we can significantly reduce the time of using the smartphone to restore the battery.

What to look for when buying an external battery

Now that we know what types of external batteries are currently on the market, we can better analyze them and find out what we should look for in order to understand that this battery is for us.

In fact, as usual, there is not one reason to choose a battery, but a combination of them. But knowing what these details to look at will make things much easier.


  • Battery capacity: This is one of the most important parts when you want to buy a device of this type, since we have to make sure that we have a battery capable of meeting our expectations. Battery capacity is measured in mAh, as is the case with our smartphone.
  • Number of devices: If we want to have a battery that allows us to charge two devices at the same time, we will see that this is something that almost all of them offer. From there, we must pay more attention and buy those that adapt to our circumstances.
  • Download speed: here it is also appropriate to see how fast the battery charge can reach. Obviously, the better it is, the less our terminal will be connected to the battery.
  • New technologies: the better the external battery, the better the connectors it will have. It is advisable to always have a USB Type C at least.
  • Weight and dimensions: Being external and taking it from one place to another, we must try to achieve a good match between the number of milliamps available, weight and dimensions, since this will make the difference between a battery that is managed and one that is not complex. carry with you, with others, which is inconvenient and difficult to transport.
  • Additional features: we can also look at some additional features that some batteries have, such as having an LED screen showing how much charge it has and devices that are connected in this way, a flashlight is also LED, some type of power strip and even some case or bag for carrying from one place to another.
