Portable solar chargers can charge devices like smartphones and cameras in locations without wall outlets.
To harness solar energy, portable solar chargers have several components, including a battery, USB ports, and one or more solar panels. They are also straightforward to set up, portable, lightweight, and available in various sizes and capacities to suit your power requirements.
We recommend the 20W X-DRAGON Monocrystalline Portable Solar Panel for its high-efficiency cells and ultra-portability.
Up to three amps per port
Portable and easy to carry
Pouch could be better designed
The X-Dragon 20W is one of the most efficient solar panels we've come across. Three monocrystalline panels offer a high-efficiency conversion rate (up to 25% of sunlight converted into energy), with each port producing up to 3 amps—suitable for simultaneously charging up to two devices.
Another noteworthy feature of the X-Dragon 20W is that it comes with carabiners, allowing you to attach it to various outdoor structures such as trees or trailer ramps. It also equally works well lying flat on the ground. It's also exceptionally lightweight, measuring 23.3" x 12.1" x .12", so it doesn't take up much space.
While the X-Dragon 20W's USB ports provide ample power, it is better suited for smaller devices like smartphones and less so for larger devices like laptops. The X-Dragon 20W is also well-priced, delivering the same power as more expensive models, making it our top pick.
Not the easiest to install
The CHOETECH Portable Solar Panel earns our top budget recommendation for its versatility. It boasts a high-efficiency conversion rate of up to 24% and includes two USB-A outputs, providing 19 Watts. This makes it suitable for charging two smart devices, such as mobile phones, external speakers, cameras, and tablets.
We also value the CHOETECH Portable Solar Panel for its durability. Its solar panels are constructed using PET polymer with a rugged polyester canvas overlay, ensuring it remains well-protected from the elements. It's a must-have for those who frequently venture into the outdoors.
Like the X-Dragon 20W, the CHOETECH Portable Solar Panel is highly portable and lightweight, weighing only 17 ounces. It easily fits into a laptop bag or backpack.
From power output and capacity to the number of panels, there are many ways to determine the best portable solar charger. We have assessed each portable solar charger based on the following factors to provide our recommendations.
Think of the kinds of devices you'll be using. Most solar panels can do the job if all you need to charge is a phone or tablet. If you need to power something larger, such as a laptop or car, you'll need a powerful setup to get the job done.
A portable and lightweight option is essential for extended trips on the road or in the countryside. Some even open up to the size of a notebook. We also applaud any portable solar charger with foldable or rollable designs, as they make transportation easier.
We advise selecting portable solar chargers with monocrystalline or polycrystalline panels boasting higher solar efficiency ratings than similarly priced units. They are more likely to convert a higher percentage of the sun’s energy into electricity. This rating also measures how quickly your charger can convert sunlight into electricity.
That depends mostly on the cells' efficiency and the amount of sunlight you're getting. Solar panels are getting more and more efficient these days, which means they're capable of generating a lot of power. On a bright, sunny day, it's not unreasonable to think you can generate enough power for a phone and tablet or even bigger items.
If it's big enough, a solar panel can deliver a charge to your car's battery to allow it to start. A "jump start" technically means you're drawing from a power source to start your car right away. The solar option is more of a car battery charger, meaning you'll need to wait some time for your car's battery to charge before you can turn the key. But yes, it is possible.
Solar panels should never be left in a window or in a car to charge. The glass from the window can focus with light on the panels and cause them to overheat. Solar panels are meant to be outside and under the sun, or put away.
