Best Backpacking Solar Charger Buyers Guide

A solar recharger may seem like a simple gadget, but these devices have a number of different aspects to them. With so many products out there, choosing the best solar charger for your travels can seem tricky! Here are some factors to explore in order to make the right decision.


If you are buying a solar charger for backpacking, then you really want it to be easy to carry around! Pay attention to the size that the charger can pack away into, and make sure that it is suitable for your needs.

While smaller chargers are great for travel, they may also be less efficient when it comes to harnessing the sun’s energy. Try to find a solar charger that is as powerful as it can be while remaining a convenient size for travel.

Charging Speed

Have a look at the solar conversion rate and power output that the charger provides. Charging more efficiently is always a top priority, so be sure to choose a solar charger that is efficient here.

Power Storage

One downside of most typical solar chargers is that they do not have a power storage function. While some solar chargers do include this, power storage is more typically found in power banks. If you spend a lot of time outdoors or hiking in the sun, then power storage isn’t a necessity. However, it can be a very useful addition to your charger.


In order for your solar charger to work, you will need it to be out in the sunlight! This means that it will most likely be exposed to outdoor elements. Having a durable solar charger is great, as you will be safer using it in rain, wind, or duststorms. If you camp, hike, fish, or spend a lot of time outdoors, then a durable charger is a good priority to keep in mind.


When backpacking or travelling, having a solar battery pack to recharge your phone is a brilliant move! You will never have to worry about losing power, no matter where in the world you may be.

This is a renewable and eco-friendly way to charge your phone. It is also seriously convenient for outdoor use. There are plenty of products out there for all kinds of adventurers, but we hope that our best solar recharging choices help you to find the perfect device for your travels! Besides a great backpack, this is a definite travel essential!
