They are often USB solar chargers, which are excellent to bring when going on outdoor adventures like camping and hiking. Portable solar battery chargers are not only great to have but are even needed when traveling to places with unreliable power grids. 

Portable solar battery chargers are also essential in emergency kits to ensure your devices will be powered up in case of calamities and sudden power outages.

If you have a trip coming up and are unsure about the availability of electricity in your intended destination, recharging batteries with solar power is the only solution. There are several available portable solar chargers in the market today, so choosing one can be challenging. This is why this article will give helpful hints and suggestions on selecting a suitable portable solar battery charger for different situations.

What to consider when choosing a portable solar battery charger?

Take a look at the factors below to guide you in picking the right portable solar battery charger for your needs.

Power output and charging

While browsing tons of solar battery charger options, choose those that are rated at 10 watts and higher. Why is that so? If you choose less, you may not get enough power to charge even just a single smartphone. In addition, choose chargers that can charge more than one device simultaneously.


Since it’s apparent that you’re looking for a portable solar battery charger, size will matter. A good charger should be easy to store and carry in bags. As for chargers for phones and tablets, they should not be bigger than an iPad. In addition, try to pick one with at least two panels – of course, the more panels, the better. That’s because you’ll need a better surface area to capture the sun’s rays, which may be elusive sometimes depending on the day, region, climate, season, etc. 

Consider the weight as well, especially if you plan to bring it when you go backpacking, so choose a lightweight one (not more than two pounds).

Additional features

It may also be great to find a portable solar battery charger with the so-called “bells and whistles.” You may find a unit with a USB cable. Or you may find another with a carabiner for easy attachment to a backpack, etc.. Perhaps you might prefer a portable solar battery charger with a flashlight? These bonus features make the portable solar battery charger easier to use and provide more benefits to the user.

Warranty and reliability

A good warranty and reliable build are indications of a good product. That’s why you must ensure that the portable solar battery charger you’re interested in buying is manufactured and distributed by a reputable brand. Don’t forget to check its warranty to ensure the product’s quality and durability.
