5 Best Solar Charger For Backpacking

Backpackers are increasingly using electronic devices in the great outdoors.

A cell phone is handy to have in case of emergency, but even away from cell service it can double as a camera, or provide mapping capacity. A GPS watch may have preloaded maps, track activity and more.

Some hikers even like to have their laptop along when out in the backcountry for long periods of time.

But having electronics means charging them, and when you’re in the backwoods, you can’t just plug into your nearest outlet. 

So a portable charger becomes invaluable. A solar charger is ideal, as long as it’s compact enough to throw in a backpack. And it has to do the job in multiple conditions.

So let’s look at the best solar charger for backpacking, first examining what to consider when choosing one.

Devices you can charge: 

You can travel with a power bank to charge your smartphone, but the life on that is also short. So a solar power charger becomes the solution to any charging needs you have. 

When choosing your solar powered charger, consider what devices you’ll need to charge. If you just want a solar powered phone charger, the decision may be easier than if you want a solar laptop charger, for instance. Check to see if the solar charger for a phone can also charge your GoPro camera, digital camera, laptop and more.


The charger you choose can either be a solar energy producer that charges a storage battery, or a solar panel that charges the electronic device directly. You have to be careful as those that charge the device directly may not have the circuitry to regulate the flow of electricity into your device.

It’s important to check the manufacturer’s recommendations, as some solar power battery chargers offer a regulated USB output that allow for direct charging.

There are two different types of chargers that include a portable solar battery. A solar panel that includes an integrated storage battery means the battery stores the power for later use as a charger. One with an independent storage battery means you can leave the panel, or power generator, in camp and take the solar battery pack with you for charging.

So it’s good to understand the specifications about the solar power battery charger and the battery if applicable.

USB Charging

At one time, you had to have a different power supply for every one of your electronic devices. Now, with USB cables and ports, you can charge your smartphone, tablet or camera into any USB port. 

So, a solar USB charger is the way to go, to ensure any device with a USB charger can be used.  A solar powered USB charger needs to generate the 5-volt standard that is required to charge a device with a USB cable. 

Size & Weight

When it comes to carrying your charger when hiking, the size of the solar charger is a factor. But the makeup of the charger can impact its power as well as its size. There are those that only have solar panels, those that have a portable solar panel with integrated storage batteries (as discussed in the battery section), or a solar panel charger with an independent storage battery.

When thinking about weight, the actual surface area of the panel obviously affects its size. But a larger panel will also collect more sunlight and convert it to power more quickly than smaller panels. On the other hand, small panels, while taking longer to charge, are easier to pack and usually lighter to carry.

A bigger surface area on the panel is also better in lower light conditions, such as in winter or partial cloud cover. Depending on the surface area and the light conditions, the amount of time it takes to charge can therefore vary.

You’ll also want to consider whether you want rigid panels, or those that are flexible enough to fold or roll up. And, you may want to choose one that can be attached to your tent or your backpack.

Then there’s the power rating. Solar panel output is rated in watts, with a higher number meaning more electricity will be generated.

Anker – 21W Dual USB Portable Solar Charger

Kiwi Camp Dry Heavy Duty Water Repellent

This compact product is ideal for hiking, at just 13.2 ounces in weight. It’s 11 x 6.3 inches, and just 0.7 inches wide when folded, and 18.1 x 1 inches, just 0.2 inches wide when opened. It has stainless steel eye-holes on each corner that allow you to strap it to your tent, a tree, or even your backpack to power it up while hiking.

It’s also durable and weather-resistant, made of industrial PET polymer panels sewn into a rugged polyester canvas holder. It’s wise, however, to protect it from inclement weather.

The ultra fast charging technology called PowerIQ delivers a charge up to 2.1 amps in direct sunlight, allowing you to charge two devices simultaneously with a solar array that is over 20% efficient. There are two USB ports for charging your devices.

The technology means you can plug right into the charger, since PowerIQ discovers and replicates the original charging protocol of any device. It also has short circuit and surge protection technology.

Included with the 21-watt, 2-port USB solar charger is a 3-foot micro USB cable. It’s compatible with Apple and Android smartphones, tablets and other USB-charged devices, but not compatible with the iPod nano, iPod Classic, iPod Shuffle, HP TouchPad and Asus tablets.

It’s important to know that this is not a battery, however, so it doesn’t hold its own charge. It’s for plugging your device into for charging, so it may not charge in indirect sunlight.


  • Extremely portable, and can even be attached to a backpack while hiking.
  • Replicates the charging protocol of your device to protect it.
  • Can charge two devices at once.


  • May only charge in direct sunlight.
