Fans of nomadism and high-tech devices are well aware: the autonomy of battery-powered devices is a crucial point. While some highly energy-hungry mobile phones do not hold the charge for more than a day, it’s hard not to miss an outlet. Yet alternative solutions exist to keep your device on for as long as possible. If the best external batteries are successful, another equally interesting alternative exists and is starting to gain momentum: the solar charger.
Besides its very ecological side – since it does not require any source of energy to operate while creating – this device allows to produce electricity in an unlimited and completely free way. Solar energy and battery technologies have made a huge leap forward in recent decades, this device is very reliable and environmentally friendly.
Functioning exactly like the traditional solar panels found on the roofs of buildings, the solar charger integrates photovoltaic cells that capture the sun and are responsible for converting light into electricity. Result: it is quite possible to go hiking, camping or picnic while being sure to have juice for your electronic devices completely independently. Best of all, the solar charger can help you out if your home is out of power.
Thus, there are two categories of solar chargers: dishes and powerbanks. The flat loaders consist of several panels that can be folded on themselves for easy transport. Once unfolded, they are fixed absolutely anywhere (on a backpack or a tent for example) to capture each ray of the sun. Equipped with USB ports, they can usually charge multiple devices at once. Tidy, they do not take up more space than a magazine in A4 format. Powerbanks, on the other hand, are boxes that can be related to external batteries. The latter host photovoltaic cells on their upper surface to draw light and turn it into energy. Also equipped with USB ports (or Lightning for owners of Apple devices), they can also charge multiple devices simultaneously. Generally compact, they also offer other functions, such as the flashlight. An excellent solution for budding adventurers.
So, if you have decided to take the plunge and opted for a sustainable and free energy to recharge your high-tech items, Bestlife4us has reviewed for you the 5 best solar chargers.

Buying Guide: How to choose the best solar charger?
All solar chargers do not meet the same needs and their uses can be multiple. Everything will depend on your ancillary equipment and its characteristics. This is the reason why there are two families of solar chargers to adapt to all situations. And if each brand has its own strengths, there are many differences depending on the model. That is why it is imperative to be well informed before making a choice. To help you see more clearly, here are the main criteria to consider when choosing the best solar charger.
Solar panel technology
There are three types of solar panels: monocrystalline panels, polycrystalline, and CIGS cells. Monocrystalline panels are usually black and are energy efficient. Also, they can work with low light but are more expensive. We find them for example on the foldable solar charger Big Blue. Polycrystalline panels are blue in color and are less expensive to manufacture. Disadvantage: their performance is less important and their thermal tolerance lower. CIGS cells offer excellent performance but are more fragile.
This is obviously the nerve of war because it is she who will determine the charging time, the number of possible recharges and the type of device accepted. Thus, to ensure a correct and fast charge for the latest generation phones and tablets, you can opt for a charger from 15 watts as the RAVPower 16W / 5V.
There are two types of solar chargers. Those with built-in battery, like the RAVPower 25000mAh, and the simple ones like the collapsible solar charger Big Blue. The first category allows you to store more energy and store it for later use. Only drawback: the integrated solar panels are not big enough to ensure a fast charge. Single chargers are composed of much larger solar panels but do not store energy. They are optimal to take full advantage of the sun’s rays. Small tip: it is quite possible to pair with an external battery to enjoy the benefits of both devices.
Their number will obviously depend on that of your devices. Generally two in number, such as on the Poweradd Appolo 2 Solar External Battery, the USB ports allow to efficiently recharge simultaneously mobile devices, tablets, and any other device with this technology. In addition, some brands have not forgotten the lovers of Apple since their models have a Lightning port, as the Power Bank 24000 mAh Bernet.
Some solar chargers are cut for adventure and have practical accessories such as an integrated LED light that can illuminate or launch an SOS in case of difficulty in the wild. Others go even further by adding a lighter, such as the Poweradd Solar Battery Appolo 2. No excuse, therefore, not to go to the discovery of sunny far away while being sure to operate its mobile devices. hours.
