Goal Zero Nomad 10
A solar charger is a very useful gadget for long backpacking trips because it allows you to easily recharge your electronic devices such as a handheld GPS device, hiking watch or a smartphone. Since many backpackers rely on these devices for navigation along the trails, solar chargers have become very popular. Especially those who use smartphones for navigation on trails (check out our test of the best hiking apps) appreciate solar chargers, because no smartphone with GPS turned on constantly runs for more than a day without being recharged.
Solar chargers absorb sunlight and convert it to electricity which charges your devices or the battery pack. Unlike regular power banks which get drained sooner or later, solar chargers are suitable for very long trips because they allow you to recharge your devices as long as you have sunlight available.
In the following we listed the best solar chargers currently available to make your buying decision a little easier. We only listed high-quality solar chargers that come for a good price and provide good durability.

4. Solar Charger Buying Advice – What is important?
Type:
There are three types of solar chargers; panels-only, panels with integrated battery pack and panels with detachable battery pack.
Panels-only
These solar chargers are the most popular because they can be used to either charge smartphones, GPS watches, headlamps etc. directly or to charge a power bank. You simply connect the solar panels to your device and the device will get charged with sunlight energy. However, before purchasing such a solar charger make sure that it is compatible with your device (connector type).
Panels with integrated battery pack
These solar chargers are usually very compact – the solar panels and the battery pack come in one piece. Therefore, they are great for attaching to a backpack. The disadvantage is that they are not modular. You can’t use the battery pack without solar panels or solar panels wihout the battery pack.
Panels with detachable battery pack
These solar chargers are basically panels-only chargers that come with a power bank. You can also use them without the included power bank.
Size and Weight:
The larger (and heavier) the solar panel, the faster it charges the battery pack. However, keep in mind that smaller/lighter solar panels are easier to pack and carry.
Type of the Solar Panels:
There are two types of solar panels: rigid and semi-flexible. Semi-flexible solar panels can be folded for easy carrying. When you need them, you simply unfold them and position them towards the sun. The main advantage of semi-flexible solar panels is that they have a large surface area despite being very small when packed.
Solar Panels Output:
The output of solar panels is measured in watts – the higher the output the more sunlight they convert to electricity per hour.
Attachment Options:
Solar panels typically have attachment points, so you can attach them securely to your backpack. Keep in mind that you need sunlight for solar panels to work and therefore you should keep them out of the backpack during the day when you will probably be hiking.
Battery Pack:
Although panels-only solar chargers can charge devices directly, it’s much more convenient to charge a battery pack (power bank) instead. Battery packs store more electrical energy and allow you to recharge your devices during the night when you are not using them. Battery packs differ in storage capacity and power output. The storage capacity is measured in mAh. The higher the storage capacity, the more times you can recharge your devices. However, keep in mind that a larger storage capacity also increases the weight and size of the battery pack. Most battery packs have a power output that is sufficient for charging electronic devices such as smartphones, GPS devices and GPS watches. However, battery packs can rarely charge bigger electronic devices such as laptops.
