10 Best Solar Chargers Reviews & Buyer’s Guide for 2020

Outdoor Solar Charger

What is the best solar-powered charger suitable for smartphones, tablets and other small electronic devices when there is no electrical outlet nearby? Today, technology allows us to recharge an electronic device in an ecological and practical way with a solar device.

All you have to do is expose this accessory to the rays of the sun and, after a few hours, thanks to its ability to accumulate energy, here it is transformed into a useful emergency battery.

The technology makes available to us portable accumulators that make the most of the various energy sources present in nature: clean, renewable and above all free energy.

Thanks to simple exposure to light, the solar charger can transform the energy from the sun into electrochemical energy, storing it inside the load cells. In this way this accessory becomes a practical spare USB battery.

This type of accessory has really interesting features that make its use safe and comfortable: among these, its ability to withstand dust and its impermeability to water stand out.

The best mobile phone solar chargers of 2020

Today we feel the need to be connected to the world at all times, not only for work but also during leisure time. But if you are away from home and suddenly run out of battery … here are solar charge energy storage batteries. They take advantage of natural light (sometimes even artificial light), to recharge any type of electronic device, from the smartphone to the tablet, from the mp3 to the GPS.

The technology provides advanced photovoltaic panels that are in little space, equipped with powerful energy storage cells. The best performing photovoltaic panels are today the monocrystalline ones but the CIGS type film panels are still available.

The choice of the most performing model must take into account the individual need for recharging, especially based on the type and quantity of devices you want to recharge, even simultaneously.

Buyer’s Guide

Solar chargers are available in a wide variety of sizes, prices and types. Small differences like the material and the efficiency of the solar panels, can have a great impact on the performance of the product and involve advantages or disadvantages.

The terrain and your recharging needs will influence your decision. Below, we will explain the key factors that will help you choose the best solar charger for your needs.


As mentioned in the previous section, some chargers are equipped with internal battery, which gives you more versatility of charging. Naturally, any solar power bank without a battery can be paired with another charger. The disadvantage of carrying a battery is related to its weight and size, but free your device during the hours of sunshine, when you have the ability to recharge the battery.

Keep in mind that with batteries that become increasingly powerful and efficient, your solar charger may be excessive. If you are hiking for a couple of days or you are spending a normal camping weekend, a battery of 10,000 mAh and more is enough to charge your smartphone twice. A solar charger is definitely an attractive option for a camp that lasts longer than three days.

Solar Panels

There are three different types of solar panels used in solar chargers. CIGS panels are the most flexible, since they are made of a thin membrane of copper, indium, gallium and selenide. They are light and cheap to make, but they degrade more quickly and have less efficiency. Therefore, chargers with CIGS panels are also the most widespread and economical on the market.

But if you’re looking for something better and more reliable, you can find polycrystalline and monocrystalline panels. As the name suggests, the former use more crystal ingots, while the latter consist of a single crystal ingot. In other words, monocrystalline panels are “purer”, have lower energy losses and greater efficiency, while polycrystalline panels are slightly cheaper to produce.

Weight and Size

Of course, the ideal solar charger should be small and light, but due to the nature of solar panels. This is an option that can hardly be conjugated. If you need more power, the greater panel sizer ideal solution for you.

The internal battery adds weight to the device with a certain versatility. Knowing your needs is essential to choose the ideal product. The combination given by a solar panel and an external battery pack gives you greater ease of transport. The possibility to choose the charger of the most suitable size and weight for you.

Efficiency and Technical Specifications

The percentage of efficiency of a solar panel specifies how much these can be effective in converting solar radiation into electricity. The better their efficiency will be the higher the percentage. Currently, they can reach values of just over 20%, up to a maximum of 24% or 25%. While polycrystalline panels are slightly below 20%, generally around 18%.

But when we go into a store or check online what solar chargers to buy, what are all those technical terms that we read and what do they indicate? Wattage and amperage are the two values to which you need to pay more attention when looking at the performance potential of solar chargers.

The electric current (the “flow”) is measured in amperes, while the electric power is measured in Watts. The 3W to 5W panels are sufficient to charge small devices, such as older smartphones and batteries. Even a whole day of sunshine may not provide enough energy to charge a hungry device like a tablet or a top-of-the-range smartphone.

With a 5W panel, a full charge may take between 3 and 6 hours. Charging two devices at the same time is only possible with a 10W panel or higher. The amperage will tell you how efficiently a device can be loaded. The values must be greater than 2A or 2.5A. Pay attention to dual output magazines, as manufacturers use different specifications.

Some will just tell you the output of both doors together. Leaving you the chance to add these values while others will specify the output of each door. A charger that can supply 2A on one port and 1A on the other is more efficient than a charger that can only provide 2.5A on both ports (and therefore 1.25A on each).


As you may have already seen, USB connectors are the standard for solar chargers, as they make it easier to charge smartphones and similar devices. On the market, you can also find chargers with different outputs, which are capable of charging 12-volt devices.

Keep in mind which devices you need to load and which connectors you need, also taking into consideration the purchase of any adapters. You can also use a battery charger powered by a solar panel, but remember that this will lose power during the conversion.

Easy To Use

Solar power banks may seem like a simple thing to set up: connect the device, expose the charger to sunlight and take advantage of the energy released. Most panels can be easily cleaned by removing dust or moisture with a dry cloth. But watch out for smart charging technology, which should be present in every good solar charger. This microchip will not only automatically regulate the charging of the connected device in terms of safety and efficiency, but also restart charging after an interruption.

This interruption could be represented by a passing cloud. The shadow of a tree that moves during the day or a person blocking the passage of sunlight. Devices without this technology can remain locked in a “slow charge” mode and require manual reset by disconnecting the charging system.

Also think about how you will top-up. Will you do it outside your tent or while you’re on a bike? Even the angle with which the device receives the sun’s rays is very important and can make a lot of difference. The general rule is that the panel should face the sun, at an angle roughly equivalent to the latitude.

Generally, this translates into more obtuse angles in summer and more acute in winter. If you make changes during the day, you also improve the efficiency of the device. A panel tied to a backpack is easy to carry, usually two-thirds of folding magazines can be hung up or down vertically, which only works if you’re walking with the sun behind you.
