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 typically consist of solar panels and a battery pack. Solar panels absorb sunlight and convert it to electricity which charges the battery pack. When the battery pack is full, you can charge other devices with it. Unlike regular power banks which get drained sooner or later, solar chargers are suitable for very long trips because they allow you to recharge the battery pack 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.

We regularly update our reviews and selections to always recommend you the best products on the market.

1. Buying a Solar Charger – 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

Such a solar charger is best for those who already have a power bank. You simply connect the solar panels to the power bank and the power bank will get charged with sunlight energy. In case that the power bank has enough capacity for your trip, you can leave the solar panels at home to reduce the weight of your pack. However, before purchasing just solar panels make sure that they are compatible with your power bank (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 you cannot detach the solar panels in case that you do not need them – for example on short overnight trips.

Panels with detachable battery pack

Such solar chargers consist of solar panels and a detachable battery pack. In case that you don’t need the solar panels, you can leave them at home (or at a base camp) and thus reduce the weight of your pack.

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 on 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:  

You typically don’t charge an electronic device directly from the solar panels because the flow of electricity fluctuates too much. Instead you charge a battery pack which you then connect your devices to for easy recharging. 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.
