5 Best Portable Solar Chargers to Keep Your Devices Charged On-the-Go

Today, the first concern when we plan any outdoor trip is to keep our devices charged. In times when Snapchat, Facebook, and Instagram stories hold so much importance, it’s essential to keep our devices charged. Even if you charge your devices full before hitting the road, you can’t expect them to stay on beyond a few hours. That’s where power banks step in.

Power banks can be savior, but they will charge your devices a few times till their charge lasts. What will you do after your power bank dies too?

That’s what portable solar chargers are for. No matter how long your trip is, having a portable solar charger with you will ensure that your personal devices are charged all the time. With solar charges, you don’t even have to worry about their charge running out. As long as you’re out in the sun, your solar charger will on its own to back your devices up during your trip.

Solar Chargers

Whether you’re stuck in the wild or want to share a picture of your child enjoying their first snow or need to use the GPS, you never have to suffer due to your device not being charged. Investing in a portable solar charger is absolutely worth it. If you’re planning a weekend camping trip or a week-long road trip in the coming days, a solar charger is something you should consider buying.

You may want to know your best options, and that’s what we’re here for. We’ve listed down the best portable solar chargers for you to choose one that meets your budget and requirements.

What to Look For

Before we take you to our list of the best portable solar chargers, you should first know what features make a solar charger the best. Below are some of the most essential features that you must look for when buying a mini solar charger.


The first and the most important feature that you should look for in a portable solar charger is wattage. Portable chargers with low wattage and high wattage both are available. If you’ve to charge your Smartphone only, a solar charger of 4 to 6 watts will be enough. For an iPhone, a solar power charger of at least 7 watts will be required as iPhone takes up a lot of power while charging. If you wish to use the portable solar charger to charge your iPad, you should consider buying a charger having a wattage of 15 watts.  The higher the wattage, the faster it’ll charge your devices. So, before you buy any portable solar charger, consider which devices you’re planning to charge and then buy an appropriate charger accordingly.

Output Power

Another important feature to look for in a portable solar charger is the output power. A solar charger works on solar panels that absorb energy from the sunlight and convert it into electrical power. The higher the output power of a solar charger, the more electricity it’ll generate in a given time. This means, if you expose a portable solar charger to sunlight for 2 hours, one that has a higher output power will get charged more (store more electric energy) as compared to one with low power output. You certainly wouldn’t want to get stuck with a charger that takes forever to get charged.

Surface Area

A larger surface area means more area of the charger is exposed to sunlight, and thus, your portable solar charger will charge faster. Portable solar chargers with a small surface area are equally efficient. They only take longer to store sufficient power in the battery. If you’re planning to somewhere where the sun comes out for a short while only, a portable solar charger with a large surface area will work best for you.

Connections or Ports

You need to consider which devices you’re going to charge in advance before investing in a portable solar charger. Most solar chargers come with one or multiple USB ports, but not all devices require a USB port. Some require other types of ports or a special adapter. See which port your device uses, and make sure the solar charger that you’re planning to buy supports that port. If not, the solar charger is of no real use for you.

Integrated Batteries

If you’re on a long trip or a business trip where keeping your devices charged is necessary, you should consider buying a portable solar charger with integrated batteries. In these types of chargers, the power generator and the battery are integrated into a single device. The power generator generates the power and stores it in the battery simultaneously.


Some portable solar chargers feature a design that may look funny and may not be very convenient to carry and use. Look for a portable solar charger that is easy to carry and convenient to use. Also, consider checking if the solar panels have any form of attachment gear that you can use to attach the charger to your backpack. It’ll make it all easier to travel with your mini portable charger.


Weight is an important consideration. Ideally, a portable charger shouldn’t be too heavy. It should be lightweight so that you can carry it with you easily, without having to bear any extra weight, especially during longer trips.


Solar chargers are quite expensive. Consider your budget before deciding on a mini portable charger. A portable solar charger without a battery may come cheaper. You can buy a battery separately.
