The 8 Best Portable Solar Chargers

What to Look for in a Portable Solar Charger?

Charging power – Bigger solar chargers typically charge your devices faster, but the wattage is a better indicator of charging power than the size of the solar panels alone. If you want to charge a phone in a reasonable amount of time, 10 to 15W is about the lowest you want to go.

Battery backup – Portable solar chargers that have built-in power banks are a must-have if you plan on using yours in cloudy conditions or at night. Look for a bigger battery if you want to be able to charge multiple devices or have extra reserve power in an emergency.

Portability – More surface area for the solar panels usually translates into more power for your devices, so folding solar chargers tend to split the difference between great portability and high output. Single panel chargers are easier to carry around, but the smaller ones struggle to provide a decent amount of power in anything resembling a timely manner.

So, let’s look at the best 8 solar chargers now – we’ve selected them very carefully! 🙂
