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.

The power

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.

Built-in battery

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.

USB ports

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.

The accessories

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.
