For many, the outdoors offer escape from the daily grind: our jobs, our email accounts, our many social media accounts. In this day and age, for better or worse, leaving at home all our gadgets that come along with our interconnected lives isn’t always an option.
Sometimes in backcountry or out on the trail, most of us would be in more trouble than we’d like to admit if forced to get by without any modern technology.
So along these electronics come, into our backpacks and onto our camping trips. To satiate these devices’ need for frequent charging, many have turned to the clean, constant power emitted by the sun.
Portable solar panels, as an industry, have made impressive strides in a relatively short lifespan. Today, several low-cost options exist that use a small surface area to capture a surprising amount of power. Once powered, many rival the charging speed of your wall outlet.
Before discussing specific items on the market, it’s important to talk briefly about what qualities we should look for in a solar charger.
In light of this, here are, in our opinion, the three best portable solar chargers for camping on today’s market.
In more ways than one, the JOOS Orange set the standard for on-the-go solar power chargers. While it’s by no means the smallest or lightest device on the market, its technical prowess is the envy of its rivals. Its ability to both directly charge devices and store energy for later use to give it a distinct advantage over other options too.
At 24 ounces, it’s lightweight enough to not be a burden on backpacking trips. It measures approximately 8.5” x 6” x 0.75”.
Shaped like a small cutting board, it doesn’t expand for use or fold down for storage. It includes a security cable hole so you can lock it and leave it. Adjustable legs on its underside allow it to be positioned toward the sun.
It doesn’t come with a case, but for all intents and purposes, it doesn’t need one.
One of the Orange’s most notable strengths is its toughness. Waterproof with a tough polycarbonate casing, the charger operates in temperatures as low as -4 Fahrenheit and as high as 140 F. No degree of altitude or humidity affects it.
Its charging power is fine for small devices: it has an output of about 6.2 Watts, enough to charge a smartphone in about an hour. While smaller can be more convenience, it’s important to keep in mind that a smaller surface area will generate less solar charge (might take longer to charge your devices).
Its built-in battery provides a distinct advantage over many competitors too. The importance of being able to store solar energy for when you truly need it cannot be overstated. In other words, when things go south, you don’t want to be hoping for good weather. Better to have the charge already built up by yesterday’s sun.
Retailed at $149, it’s not the thriftiest choice, but its website makes bold claims about its value. It claims to charge at least three and a half times faster than any equally priced competitor, for instance, and that it’s simply “the best solar charger under the sun.”
No aspect of the charger is perfect: it could be lighter, it could be more compact, and it could certainly have more charging power. Taken together though, it’s hard to argue against the claim that this is an exceptionally well-balanced solar charger suitable for almost any mobile need.
Comparing the Solaris with the JOOS Orange provides for stark contrast. While the Orange gives modest, reliable charging power for small devices no matter the situation, the direct-charging Solaris, for considerably more moolah, gives you nearly five times the charging power.
The Solaris comes in the often seen blanket-style solar panel setup, folding up to a pleasingly compact 8.5” x 11” x 2” package (21.5” by 37.5” when unfolded). While it’s not as wear-and-tear as the JOOS Orange, its size makes it a fine choice for short-distance or car camping.
Here’s where the Solaris really distinguishes itself from the pack. Compared to the 6.2 Watt output of the JOOS Orange (which, as a reminder, is very good for compact panels), the Solaris has a maximum output of 26 Watts.
In practical terms, this means you can bring a lot heftier devices to life with this thing. DSLR camera batteries and tablets would be easily managed, although laptops would likely take the majority of a day to charge. The Solaris 26 makers claim smartphones can expect to be fully charged in under an hour.
It’s also important to keep in mind that this is a direct-charge panel, meaning it doesn’t have a battery pack like the JOOS does to store power for later use. This means you’ll need to either buy an external battery to bring with it or hope for sunny weather.
$550 retail (or $350 on Amazon). The extra price may be worth the boost in power for many though. If you have a laptop, a high-powered camera or another device that sucks more juice than a smartphone, this might be the wattage you’ll require if you’re set on using solar. A JOOS Orange simply won’t cut it, unless you’ve got a full day to spare.
Last but not least is the Anker 14W, a compact, no-frills direct charger with a considerable surface area, low cost and high power output.
As with the Solaris 26, the big disclaimer here is that while it’s a third of the price of the JOOS Orange, it’s a direct-charge panel, meaning that there’s no battery that stores up the charge. You can only charge your devices while this is out in the sun (unless you bring a battery pack). So be wary, if you need to power a device at night or on a rainy day, you’ll be in trouble.
Another blanket charger, the Anker’s polyester canvas adds a degree of durability sufficient for backpacking, but not the reckless disregard the JOOS affords. It’s fairly compact (11” x 6.9” folded) and weighs 1.8 pounds.
Metal-rimmed eyeholes on each of its four corners allow for easy mounting. It’s equipped with two USB ports, letting you charge multiple devices at once. With a 14W output, that’s actually a realistic endeavor.
As mentioned above, the Anker has a robust charging speed (14W), that will make charging smartphones an easy task. Tablets and similarly powered devices won’t be insurmountable either, although it would likely take several hours to get a full charge.
The lack of an internal battery means that you’ll need to shell out money for an external battery source, or be at the mercy of Mother Nature. If you’re in a far flung area and need to power a device in an emergency, praying for good weather isn’t the safest practice.
At $49, this is an investment most outdoor enthusiasts can make without much burden. Although it shouldn’t be relied upon too heavily without an accompanying battery pack (unless you’ll be using it somewhere with an overwhelming amount of direct sunlight), it would be a good companion on most camping trips.
While all of the above devices are a good start in general, it’s still important to take your personal usage needs into consideration.
The most important consideration is likely to get smart on your personal electronics power demands. For example, a GPS with rechargeable battery might have a capacity of 2000-2400 mAh, while a smartphone might range from 1200-2100 mAh.
