A solar charger is a great gadget for long backpacking trips because it allows you to easily charge your electronic devices, such as handheld GPS devices, hiking watches, or smartphones. Solar chargers have become very popular since many backpackers need to rely on these devices to navigate along trails. those of you who use your smartphone to navigate trails, in particular, really appreciate a solar charger, as no smartphone with GPS turned on lasts more than a day without charging.

Solar chargers charge your device or battery pack by absorbing sunlight and converting it into electricity. Unlike regular power banks, which run out sooner or later, solar chargers are better for long trips because they can keep your devices charged whenever there is sunlight.
