Everything you need to know about portable solar battery

Although technology has come a long way, some components have lagged behind. A good example can be found in the batteries in our mobile phones and tablets.

While it is undeniable that they last longer than before, it is rare that they can last for hours under heavy use. This is where the portable solar battery appears as an interesting alternative that allows you to significantly increase the autonomy of the internal battery of any device.

If you don’t know them yet, you will be very surprised at what you will discover. We have prepared this article in which we analyze their main peculiarities.

What are portable solar batteries?

The portable solar battery, also known as the solar power bank, is a device used to recharge other equipment without having to connect them to electrical power.

It is made of small solar panels that have the ability to attract and use the energy that comes from the sun’s rays. It is therefore an interesting device, as it will not be necessary to use a power source in order to continue recharging. If you are interested in this type of charging station, you can discover the EcoFlow portable solar batteries here.

Is it really worth having a portable solar battery?

Owning this device is highly recommended if you travel non-stop and love outdoor adventures. But since you use your smartphone for everything (to study, work, check your social networks or just to communicate), it is also a perfect device for everyone.

The way to recharge is very simple. It is necessary to expose the small plate to the sun. This might make you think that it will only work when there is sunshine, but that is not really the case.

These devices can also work on days when the sun is less or on days when the weather is cloudy. However, it should be taken into account that charging will be much slower. But FYI, the portable solar battery can also be recharged using electricity if needed.

What is the difference with a solar charger?

If you are already familiar with solar chargers, you might confuse them with the concept of solar power bank, you might even think that it is the same but with different words. The truth is that the function of both devices is quite similar.

However, the batteries are portable with the capacity to store the energy that comes to them from the sun, but they can also be charged on the sector.

In contrast, a solar cell charger does not have an internal battery or similar. Its only job will be to act as an intermediary between the sun and the device it wants to charge.

That is, it captures the energy and moves it to the device in question, but under no circumstances can it accumulate it for later use. Once it loses contact with the sun, the solar charger will be useless. In this respect, portable solar batteries are much more versatile.

How to choose a portable solar battery?

Now that you know the most important features of the portable solar battery, you will definitely want one for your next expeditions. Just do a quick search on the market to discover that there are plenty of options to buy.

To avoid buying a device that you are not interested in or that does not meet your needs, there are a number of factors that we can guide you through. In this section, we have prepared a practical buying guide for choosing a portable solar battery.

Battery life or capacity

Battery life or capacity is a key criterion not only when choosing a portable solar battery, but when purchasing any type of battery. This factor is measured in milliamps or mAh. It is more logical to think that more mAh increases the charging capacity, but the technology with which the battery is designed also has an impact.

To have a reference value, we recommend investing in a model that has at least 10,000 mAh. With this value, you can make about five loads on your mobile phone and two loads on a tablet. It is therefore also important to know the use that will be given to the device before making your choice.

Placement of integrated plates

Note that the energy enters the battery via the plate or the integrated solar panels. It is therefore very important to check the placement of the solar panel to determine if it is designed logically.

The interesting thing is that they are located in the longest areas of the battery, as in this way they can get the most of the sunlight. Beware of batteries that have built-in plates that are too small or that are placed in places that don’t seem very logical.


Even if you take care of the battery, you can accidentally drop it at any time. If you don’t want it broken on the first change, go through the protections. The best batteries have optimal protection that will protect almost anything (they can even give you some water resistance).

Although the price increases for protection, it is good to get a good ratio between a model that gives you high quality materials and can be had at a reduced price.

Height and weight

In addition to the above criteria, dimensions and weight are also considered key criteria for choosing a good portable battery.

If you take it on an excursion, a trip, to work or elsewhere, you must check whether it fits in your suitcase. The same goes for the weight: if it’s too heavy, moving it will probably be tiring.

Thanks to these factors, you can get a portable solar battery that matches what you are looking for!
