Best solar chargers for mobile phones - portable and lightweight solar battery charger

Let's read our reviews of the best solar chargers for mobile phones to have the top-rated portable solar battery charger for your Android or iPhone.

Our phones have become essential to communicate, study or work. We are still waiting for that infinite battery that ends with the excessive dependence on the battery of our devices. Although we have seen some smartphones with good battery life in 2018, but still not enough for our day to day busy life. While we wait for that day to arrive, one of the ways to keep our mobile phone charged whenever we want is with the use of a portable external battery charger or with a portable solar charger. Today, we will talk about the best portable solar chargers for mobile phones.
Before presenting our list with the best solar chargers for mobile, let us know in greater detail this accessory and its characteristics.

Why should you buy a portable solar charger?

The truth is that this is a useful product for people who travel, make trips, hiking, for example. Its compact size and practical use are the solutions to those looking for a portable charger.
By relying solely on the sun, it is possible to save time when charging your mobile or other devices (cameras, speakers ...) while you move from one place to another with the solar charger behind you, without needing a plug.
As a small inconvenience in this type of chargers, it is necessary to know that most do not include an internal battery (such as power bank). So it is recommended a correct exposure of the sun's rays on the panels of the solar charger so that the charge of the mobile is faster.

How does a solar charger work?

A solar charger is formed by one or more solar panels. Each panel or solar panel is composed of small photoelectric cells, usually made of silicon (material suitable for transmitting electrons), which can be high quality monocrystalline or polycrystalline, with lower quality and lower results.
One of the biggest limitations of these solar panels, apart from the material used to manufacture them, is the small amount of energy they collect per individual cell.
That's why you would need to use large panels (which would be impractical in our case) or, what is usually done, connect several small panels in parallel that are later deployed to capture more solar radiation.

Types of solar panels: Monocrystalline vs Polycrystalline

When deciding on a solar panel, most users ask themselves this question, which is the best? If we want to know, we must bear in mind that the performance of a solar panel will decrease as the temperature increases.

Monocrystalline panels:

They are the ones that attract the most radiation when they have a darker color cell. This makes them more recommendable for cloudy or low radiation days.

Polycrystalline panels:

They are more bluish in color and reach lower temperatures, so there is less loss of performance and is recommended for days of full sun.
There is, therefore, no perfect solar panel for every day. If we make an annual average we will have a better behavior in a monocrystalline solar panel in the months of low solar radiation and worse in the months of higher radiation to give an example. The solar chargers of the brands we recommend work with monocrystalline panels from the SunPower manufacturer that have an efficiency in their panels of more than 20%.
Therefore, when deciding on a solar charger, what really matters is that we look for the one with the best price, quality and use needs, without giving more importance than necessary if the panel is made of a material or another.

According to the power (W), what solar charger should I buy?

The higher the power output of the solar charger, the faster the connected devices will charge since the USB ports will have a higher capacity to satisfy the power demand of each connected device. However, two key factors must be taken into account:
Devices that you will use with the solar charger 
It is the first question you should ask yourself and be clear: what and how many devices do you plan to use with the charger? It is convenient to know this because the prices of solar chargers vary greatly depending on the power that can be supplied. That is, if you are going to recharge 2 or 3 at the same time you are interested in buying a solar charger with a higher power. On the other hand, if its use is occasional and for a single device such as a mobile, with a charger between 15-20W it would be more than enough for a fast charge.
How the sun's rays strike the solar panel? 
Assuming a sunny day, to have a good performance and, therefore, more power at the exit you have to place the solar panels so that the rays strike perpendicularly on them.

Power bank solar: advantages and disadvantages regarding a solar charger

Advantage: flexibility

With a power bank with the solar panel, you can store solar energy in an internal battery and then use it to charge the device. As you can see, this allows a greater flexibility than with a solar charger, with which you would have to connect at the same time the device to recharge during the solar exposure of the charger.

Disadvantages: power and charging time

1) The drawback of external solar batteries is their charging time, the solar panel they incorporate is very small, that is, they have a reduced sun exposure area that would involve many hours for a full charge of the battery. However, they can also be recharged like any power bank through the micro USB port. This same problem happens when you are going to recharge a device with the power bank through its solar panel.
2) If the power bank has no energy stored in its battery and you have to resort to charging it through the "mini" solar panel then the time to charge the device will be much greater than with a solar charger.
Therefore, from our point of view, the solar power bank should be used as a normal power bank, that is, recharge it whenever possible with the micro USB port and, exceptionally, use its solar panel. If you are looking to charge your devices directly with solar energy then we recommend that you use a solar charger that is specially designed for that.
