Anyone who has a smartphone knows how important it is nowadays to have a battery with a lot of autonomy, not only when you are traveling, but also to stay in touch with work or more simply, for any emergency.
Today we use cell phones so much that sometimes the battery doesn’t last for a whole day. One of the most innovative solutions on the market is undoubtedly solar chargers.
Do you already know what we’re talking about? Have you already tried them? Solar smartphone chargers are rather new items and have only recently gained popularity in the market.
If you don’t know how they are or how they work, don’t worry. You have come to the right place! In this guide, we will provide you with all the basic information about solar smartphone chargers.
Right below we had listed out the best solar chargers.
Buyer Guide to Choose the Best Solar Powerbank
Sun no longer means only summer and the beach. Taking advantage of the good weather, most people move away from the city in search of calm and re-establish contact with nature, a truly wonderful way to relax and not think about problems.
As long as the smartphone runs out of battery, argh! Fortunately, in such a situation it will be possible to use the solar charger. In this section, we will try to answer the main questions about this product.
What Is a Solar Charger?
A solar charger is a portable device that transforms photovoltaic solar energy into electricity, which can then be used to recharge smartphones or tablets.
These solar devices are capable of charging batteries up to 48 V (Volt) and hundreds of Amperes. Often they are equipped with an intelligent charging system.
What Is a Solar Charger Made Of?
The solar charger consists of one or more solar panels. In turn, each solar panel is made up of small photocells, normally made of silicon (the most suitable material for transferring electrons). One of the major limitations of these solar panels is the small amount of energy that each photocell collects.
How Does a Solar Charger Work?
When you leave the charger in the sun, the photovoltaic panel absorbs solar energy and then transmits it to other devices, such as a mobile phone or tablet. Normally, the smartphone and the solar charger are connected with a micro USB cable.
The time required for the charger to fully charge depends on both the efficiency of the solar panel and its surface.
What Is a Solar Charger For?
The different types of external chargers are very popular, especially among those who are always afraid of running out of battery on their mobile phone.
Among these items, solar models are gaining more ground thanks to their ease of use (they depend only on the sun) and their sustainable nature. Among the multiple advantages of these devices we can also find:
- They allow savings from an economic and energy point of view because they do not depend on electricity.
- They do not require special maintenance, in addition to some normal precautions (such as, do not expose them to excessively cold temperatures).
- They allow you to charge your smartphone or tablet in virtually any situation: while walking or cycling or during other outdoor activities.
- Thanks to the sustainable nature of the article, the guarantees offered by the manufacturers are generally long (two years as a minimum) and the useful life of the transformer can be up to 25 years, even in the case of constant use.
Do Solar Chargers Contains an Electric Battery?
Not all models, but almost nowadays, are equipped with an internal electric battery. An internal battery will allow us to choose how to recharge the smartphone, whether using the internal battery previously charged with electricity or using the sun’s rays.
From a certain point of view, it is an advantage, because it will always give us the possibility to recharge our device, regardless of the situation in which we find ourselves. On the other hand, these hybrid models are not as effective as exclusively solar ones.
Can Solar Chargers Be Used Every Day?
This is not recommended. These chargers have many advantages, but they certainly do not guarantee the same performance as conventional chargers or external batteries, which depend on electricity.
Solar smartphone chargers are small in size and therefore can store limited amounts of energy. However, they prove to be very useful as emergency chargers, especially for when we are outdoors.
When using these devices we must also consider that, due to the small size, the time to charge the smartphone may be longer than conventional devices. For this reason, we repeat, it is mostly an emergency (and not routine) charging system for charging small devices. It can actually get you out of trouble!
Maintenance Required by Solar Chargers?
Another advantageous feature of solar chargers is the low maintenance they require, however it is essential to use them properly so that they can work properly and ensure optimal performance.
For example, cleaning a solar charger is very simple but at the same time very important operation. Just spray a little water, possibly avoiding cold water to avoid thermal shock.
How to Choose the Best Solar Charger?
Until smartphones with an unlimited battery are produced, we will continue to need external chargers in order not to run out of battery. Solar battery chargers for smartphones today are an effective solution to help us in different situations.
For example when we are traveling or when we are doing outdoor sports. If you encounter difficulties when choosing a model, we recommend that you consider the factors.
Before that, we had shared the video guide on how to choose and properly used the solar chargers.
Power and Charging Time
The power of a solar smartphone charger is one of the first factors to consider before making the purchase. This is a characteristic expressed in milliamps per hour (mah).
The power required to recharge the battery will depend on the power, therefore, if the power is high, the charging time of the battery will be shorter. We advise you to buy a model that has a minimum power of 1000 mAh.
Among the various models of solar battery chargers for smartphones, there are some that allow you to recharge different devices at the same time. This feature proves very useful during trips and excursions with friends.
If you plan to use the charger for more than one device at a time, then make sure that the model you have chosen allows it, and that it maintains adequate power.
The aesthetic characteristics of solar smartphone chargers change according to the brand. Being devices that we always carry with us, it will be convenient to choose a light and small model.
At the same time, however, remember that the larger the surface of the solar panels, the greater the reception of solar radiation. The aspect to be privileged will, therefore, depend on your needs.
