What is a Solar Charger
A solar charger has one or multiple solar panels combined in a single device which can accumulate the power and transfer it to devices that need to be recharged. The charger can even power laptops along with mobile phones, players or tablets. You will never get lost because your GPS battery has run out of power. You can recharge the GPS with your mobile solar battery! Many solar chargers are flexible and can be folded to a very compact size. You definitely need this high-tech assistant for your hikes and travelling.

What Features to Compare
The main features of any solar charger are, probably, its operation mode and available functions. Before making a choice of a charging gadget, you should take into account some important criteria that will help you choose a particular model satisfying your needs and compatible with your mobile devices. Individual chargers may be incompatible with certain models of smartphones or tablets. Other devices might be incapable of charging laptops or might have only USB or micro-USB ports. You should study the input and output ports every gadget has. A charger can be powered directly from solar panels or via a built-in rechargeable battery which can be charged from the mains or solar panels in its turn. The peak power determines how fast your devices will be recharged, whereas the transformation efficiency defines which share of solar energy is converted into the electricity. The more efficient the charger is, the better and faster it will make the batteries of other devices full.
A design is another important criterion affecting the choice of a solar charger. The exterior is sometimes the priority for some users. You always look at the appearance first and only after that start assessing specifications and functions. If a device looks good and features versatile functions at the same time, you may buy it without hesitation. Some chargers have several solar panels assembled into a single foldable construction. If it is sufficiently compact when folded, you should pay particular attention to this device. You can't carry a large solar panel when you go hiking, for example. But, if you select a foldable one, you will be able to store it in a pocket of a backpack and take it out and unfold whenever you want.
An independent power source will always be useful for a hike or travel. However, it might be not that convenient to stop, unfold the solar panels, and wait for the charger’s power bank or a device to get full. That is why producers provide their chargers with such accessories as carabiners, clamps, and so on to attach panels to backpacks, tents, trees or other surfaces. The charging will take place while you are walking, riding or doing anything else you want. The manual with detailed instructions will inform you about all features of your gadget and the best way to use it. Extra connection cables included in the package will save your money and time.
