One of the most innovative creations of the 19th century, solar technology gives you the literal ability to harness the sun’s energy. Sure, when Edward Weston patented them in 1888, they were neither compact nor lightweight. But, fast forward to the present day and this technology is portable and tons more efficient. While it might be a bit of a leap to retrofit your entire electrical grid to solar, it doesn’t mean you can’t benefit from the technology. One of the most popular uses, in fact, is giving outdoor enthusiasts access to clean, efficient energy wherever they go. You can tuck a solar charger in your backpack and hit the trails; then, whether you need to boil water or recharge your phone, it’s right there. All you need is access to the sun and the help of one of the best solar chargers for backpacking, and you can make the great outdoors much safer and more convenient. This piece details the top models, along with some tips on finding the ideal solar-charging travel companion. Let’s get down to it.
The Best Solar Chargers for Backpacking

Best Solar Chargers for Backpacking Buying Guide
Backpacking in the modern age makes traveling with some type of power source more than a convenience — it’s a necessity. You can’t exactly haul around a generator, and your phone won’t run on triple-A batteries. That’s where a solar charger comes into play. Imagine getting lost in the wilderness and seeing that dreaded flashing battery signal, informing you that mere moments remain. Taking along a solar charger is a lot easier than facing that struggle.
Of course, not all solar chargers are made alike. It all comes down to picking an option that works for you. Balancing weight and bulk with charging ability is key. You want something that will fit in your backpack without taking up too much room. Plus, it needs to be durable enough to resist the harsh conditions of the great outdoors. As long as the charger meets these needs (and is compatible with your devices), then you can reap all the benefits it has to offer.
The Advantages of Owning a Solar Charger for Backpacking
There’s no shortage of advantages to owning a solar charger for your hiking excursions. For one, they are designed for travel. Lightweight and portable, these devices are built to fit into tight quarters with most models folding down. Expanding to display the solar panels, many even have openings to attach to your backpack, letting you charge your devices while you walk.
A lot of solar chargers even feature a power bank, giving you the ability to gather power when the sun is out and use it later. Those that don’t offer this feature usually have high conversion efficiency, making the most of the sunlight while it’s in use. Often, there are multiple USB ports so that you can charge your flashlight and your phone.
Ultimately, taking a solar charger along is about more than checking your Instagram while you’re on a hike. It’s a survival tool that can help you get out of an emergency more quickly and more safely. That’s where the true advantages lie.

- Solar chargers are compact and foldable, tucking into your backpack.
- Waterproof models are able to resist damage from the environment.
- Protective covers are there to prevent scratches and cracks.
- Even a few minutes of direct sunlight can return power to a dead phone.
- Solar chargers are reusable and built to last over the long term.
- Eco-friendly by nature, this survival gear creates clean energy.
Popular Types of Solar Chargers for Backpacking
Though the main purpose of any solar charger is to convert energy from the sun into usable power, there’s more than one kind from which to choose. Getting the most out of your solar charger system is a matter of identifying the right type for your needs. The technology is all loosely the same, and the difference lies in how it uses the power it generates.
The most common type of solar charger for backpacking consists of between two and five panels, connected to optimize the amount of energy harnessed. Typically, these are covered by a clear polymer to prevent water damage. Backed with a textile (usually canvas), you can fold them down without risking scratches.
Generally, these range in efficiency from as low as 21 percent to as high as 25 percent. Depending on the model, it will incorporate up to four USB ports. Often, there is one large and one micro USB component so that you can charge any device. This type of solar charger tends to be the most lightweight and compact, though it requires direct exposure and can only provide power when it’s exposed to the sun.
Panels with Power Bank
Though less popular, solar chargers that come with a built-in power bank have some extra benefits. They look similar to regular folding panels, though tend to be heavier and somewhat bulkier. This is due to the power bank itself. Basically a battery, it takes on power while the charger is exposed to sunlight and stores it for later. As a result, you can use the sun’s energy even in cloud cover or at night.
Because of the extra electrical components, there need to be more safeguards against overheating, overcharging, and water damage. This adds to the size and weight, but only nominally. Often, because of the fact that these solar chargers can hold onto power, they will feature fewer solar panels. The conversion efficiency is the same as with the standard panel models.
Features to Look for in Solar Charger for Backpacking
When tracking down the best solar chargers for backpacking, there are a few features to keep at the forefront of your mind. There’s a big difference between a solar lantern and a sun-powered charger for your car. Getting the most use out of the technology relies on finding the right fit, so check out these essential features to be sure you’re getting your money’s worth.
Measured in watts, the output refers to the amount of power the device can supply. After the solar energy is taken in through the crystal structures on the panel, it is converted into raw electrical energy. Look at the conversion efficiency of the solar panels to see what you are getting. Aim for higher wattage and better efficiency (upwards of 22 percent, if possible). Whether you’re getting a hoverboard charger or something smaller for your hiking trip, being able to draw more power more quickly is important.
The type of panels used dictate the durability of the device itself. If you are going camping with your motorcycle, you need something that can withstand damage. Though it may sound like rigid panels are tougher, they are also more vulnerable to cracking due to impact. It might not be a concern if you are keeping the charger as an accessory in your RV, but backpacking leaves the charger somewhat more exposed. Aim for semi-flexible panels, the more forgiving type which is less inclined to break under pressure.
The charger won’t be good for anything if you can’t plug in your devices. Some technology requires a micro USB port in order to recharge. While the vast majority of solar chargers have regular USB components, the smaller counterparts are less common. Keep an eye out for models with multiple charging ports, especially since this is the part most prone to wear and tear. This way, if one gets damaged, you can keep using the charger.
Because this technology deals with electricity, there ought to be some measures to prevent issues like overcharging and overheating. Unlike AC or DC systems, these chargers won’t stop automatically. Be sure that it opens well enough to promote airflow when in use, as it can help with overheating. Check for a durable cover to prevent damage from abrasion; and, as long as you use the charger carefully, it will last over the long term.
