Stuck outdoors without an outlet? It’s time you pack a portable solar charger. Much like a portable battery pack, portable solar chargers allow you to charge and recharge your phone and other devices, only instead of using a plug to power up, it harnesses the power of the sun.
These devices come in a few different size options and are capable of generating enough power to keep you connected. Depending on your preferences, there is the option for a solar panel-like device with solar cells that is foldable, small in size and attaches easily to your backpack for continual light absorbance. Another option is the smartphone-sized portable chargers that you can hold in your hand or pocket for ease of use.
The most important thing to note about these portable chargers is their handiness for emergency situations. While not the most ideal for use as your primary charging source, these chargers, when fully charged, are integral when and if your cell phone runs out of battery during any outdoor activity. These chargers are also all water and dust-resistant, can charge multiple devices simultaneously and can be used anywhere in the world.
