Best Overall 100-Watt Solar Charger For Camping

Jackery SolarSaga 100

REASONS TO BUY
Less expensive
Energy efficient
Straightforward to use
Lower weight
REASONS TO AVOID
A bit large when folded
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 68 Wh
Power Output Rating (Watts) 100 W
Energy Generated in 1 Hour Indirect Sun 25.8 Wh
Measured Output in Direct Sun (Watts) 62 W
Measured Output in Direct Sun (Volts) 20.6 V

The Jackery SolarSaga 100 once again is our favorite high-wattage solar charger. This lightweight panel is more affordable than most 100-watt solar panels and also performs as well as the best of them. It’s user-friendly and effective in full and partial sunlight. If it’s a sunny day, this panel charges your devices quickly, and it works well on cloudy days as well. When it’s time to pack up camp, the SolarSaga quickly folds flat and weighs just over 10 pounds. The low weight and simple fold-in-half design make it easy to load into your car, so it’s always ready for your next adventure. It has tons of useful features that make it portable and exceptionally useful, including a built-in handle that makes it easy to carry. The legs fold out easily and quickly. With a USB-A, USB-C, and a DC output, you can plug this directly into your solar power station or power any of your devices straight from the panel. The DC charging cable is hardwired into the panel and stowed into a zipper pocket along with the USB charging ports. This solar panel impressed us in every way, making it an excellent addition to any off-grid solar setup.

Even though the SolarSaga 100 is relatively lightweight and folds flat, it doesn’t fold down as small as many other 100-watt panels we reviewed. It only folds once, so its folded size is quite wide. At the same time, this single fold means it’s thinner than many other models in our lineup. It’s about as packable as other panels, but you’ll need a slightly wider space to fit it. Also, the single-fold design makes it faster to pack away than most other models, making up for its slightly larger packed size. If you are shopping for an all-around great 100-watt solar panel for your camping adventures, look no further than the SolarSaga. If you’re looking for a more portable option, we also love the user-friendly BioLite Solar Panel 100, and for our favorite of the smaller portable models, see the BigBlue SolarPowa 28 below.

Best Overall Portable Solar Charger

BigBlue SolarPowa 28

REASONS TO BUY
Efficient conversion rate
Lightweight & portable
Does well on cloudy days
Affordable
REASONS TO AVOID
Doesn’t have kickstand legs
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 1639 mAh
Power Output (Watts) 28 W
Energy Generated in 1 Hour Indirect Sun 872 mAh
# of USB A Outlets 3
# of USB C Outlets 0

Of the smaller panels, the BigBlue SolarPowa 28 is the top dog of portable solar chargers. The BigBlue is impressively efficient in its charging capabilities and performed the best in all our testing of portable solar panels. This model is the fastest portable model we tested, and it delivers consistent charging even as conditions change. Whether it’s cloudy or sunny, you’ll get good charging capabilities from this model. It has three USB ports, which lets you keep all your electronics charging simultaneously so they’re ready when you need them. And when you’re ready to move on, this panel folds up small enough to fit in your backpack.

The SolarPowa 28 isn’t the absolute fasting charging portable panel, but it still charges fast enough. And if you need an ultralight solar option, this panel also might not be the best choice. At 21.8 ounces, there are certainly lighter models out there to consider, like the Goal Zero Nomad 5. But if you need a lot of consistent power in a relatively portable size, the BigBlue is a great option we highly recommend. And it’s pretty affordable to boot.

No place to store cables
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 66.7 Wh
Power Output Rating (Watts) 100 W
Energy Generated in 1 Hour Indirect Sun 21.6 Wh
Measured Output in Direct Sun (Watts) 64W
Measured Output in Direct Sun (Volts) 21.4 V

In terms of larger 100-watt solar panels, the BigBlue SolarPowa 100 ETFE is the best value around. This model costs significantly less than pretty much every other panel we tested. But that’s where the differences stop because this performs almost as well as the more expensive large solar panels. It’s lightweight and portable with a carry handle and foldable, ultra-portable design. You can easily load it into your car and unload it at a campsite quickly. It has fold-out legs, so you can point it directly at the sun to maximize low-angled morning and afternoon light. It comes with a variety of adapters that make it compatible with most power stations from any brand, eliminating the need to purchase additional cables or adapters. This adds to the already great value of this panel.

The SolarPowa 100 is a great solar panel for the price. It’s easy to use and effective, and it comes with a variety of adapters, so you can charge most devices. However, it doesn’t have a pocket or other storage case for those adapters or the main storage cable. We ended up transporting this with the cables wrapped around the panel, which worked but wasn’t ideal. Overall, we think the SolarPowa 100 is a great, high-value option for anyone looking for a reliable and affordable solar panel. If you’re seeking something that’s fully waterproof with fast charging speeds, the EcoFlow 110 can do the job in a more portable package and a similar price range.

Lightweight for its size
REASONS TO AVOID
Awkward pouch makes the panel lay strangely
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 1193 mAh
Power Output (Watts) 20W
Energy Generated in 1 Hour Indirect Sun 676 mAh
# of USB A Outlets 2
# of USB C Outlets 0

When you’re adventuring outside, a fast-charging portable solar panel is key. The X-Dragon 20W quickly charges all your devices in a small, reliable package. This 20W portable solar panel isn’t particularly expensive and works with reasonable speed, charging all your devices quickly. It has a high conversion rate, so this panel charges well under sunny skies and on overcast days. Each of the X-Dragon’s panels generates up to three amps, which is an exceptional amount of charging capacity for any USB device. It’s also lightweight and hangs up easily, making it a solid choice for quick juice-ups on the go.

The X-Dragon folds down to the size of a notebook, so it isn’t the smallest portable panel out there. But it unfolds into three panels to capture an impressive amount of sunlight for its relatively small size. If you’re looking for a higher-capacity backpacking solar panel, a super portable panel to charge at base camp, or simply need an affordable solar panel to harness energy from the sun, you should check out this model. Don’t bypass our favorite portable solar charger, the BigBlue SolarPowa 28, which is only a few dollars more for faster charging speed and better functionality.

Portable Medium-Capacity Setup

FlexSolar 40W

REASONS TO BUY
Unfolds and packs away quickly
Portable package
Multiple USB outputs
Rapid DC charging
REASONS TO AVOID
No protection for ports
Not as light as some portable panels
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 972 mAh
Power Output (Watts) 40 W
Energy Generated in 1 Hour Indirect Sun 461 mAh
# of USB A Outlets 1
# of USB C Outlets 1

The FlexSolar 40W is a high-output, easy-to-use charger that can quickly unfold from the size of a large book into six linked solar panels. This medium-capacity panel has a DC output that can charge portable power stations, as well as USB-C and USB-A outputs for smaller devices. For its medium-sized capacity, it is relatively portable and folds up quite small. It doesn’t use any clasps, magnets, or velcro to secure close, which makes unfolding this into a large six-panel array a cinch. And those six panels put out a lot of power, then fold away just as quickly.

While the FlexSolar 40W does fold down into a very small size, it’s not the lightest panel we tested either. It weighs just shy of three pounds. That’s nearly twice the weight of some other 20-30-watt panels, though less than many 50+ watt panels. There are no covers for the charging ports, so those USB and DC outputs are susceptible to dirt and debris. This hasn’t been an issue for us yet, but we’ll keep you posted if it does. If you’re looking for a midsized option that can power larger devices yet still remain very portable, this is a great choice. Another option we like is the X-Dragon 20W. It’s great if you’re looking to go small and light, and it will save you some money.

An Ultra-Compact Large-Capacity Panel

BioLite Solar Panel 100

Power Output: 100 W | Weight: 9.5 lb

REASONS TO BUY
Super portable
Lightweight
Easy-to-use
Simple setup
REASONS TO AVOID
Slower charging than some panels
Expensive

The BioLite Solar Panel 100 is the most portable 100-watt solar panel for camping we’ve found. This model is lighter, thinner, and more packable than most large-capacity models we tested. You can easily slide this into your trunk, with plenty of room to spare for all your gear. It has a comfortable built-in carry handle and zipper pouch, which makes it painless to haul this to your solar charging station at camp. It unfolds in a snap and has two pop-out legs to complete the setup in seconds. With a handy sundial, you can more easily angle this panel directly at the sun, and it’s easy to daisy-chain together with more BioLite panels to grow your charging station capacity.

While the BioLite 100 has great portability features, it isn’t the most efficient panel in terms of energy conversion. It’ll definitely power your small devices better than many panels, proving itself just above average in our testing. This is also one of the more expensive panels we’ve seen. But it has tons of great user-friendly features and is super portable, which makes up for the just-okay charging speeds and the higher price tag. If you value performance over portability, take a look at some of our other top-scoring models, like the Jackery SolarSaga 100 or the EcoFlow 110.

High Performance in Any Weather

EcoFlow 110

REASONS TO BUY
Fast charging in sun and under clouds
Waterproof connections
Lightweight design
Portable size
REASONS TO AVOID
Charging cable doesn’t come with it
Case makes for a subpar kickstand
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 67.2 Wh
Power Output Rating (Watts) 110 W
Energy Generated in 1 Hour Indirect Sun 33.2 Wh
Measured Output in Direct Sun (Watts) 61 W
Measured Output in Direct Sun (Volts) 21.4 V

The EcoFlow 110 packs an impressive amount of charging capabilities into a small and lightweight design. This 110-watt solar panel charged our devices impressively fast, even among stiff competition from the other large panels we tested, on both bright sunny days and in gloomy overcast conditions. It folds four times and comes with a zippered carrying case, which makes it easy to bring with you wherever you’re setting up your solar charging station. This is also one of just two large solar panels we tested that is completely waterproof, so you can set it up and not worry about a little rain rolling through.

Just about everything about the EcoFlow 110 is great. However, it is one of the few models we reviewed that doesn’t include all the necessary cables, adding to its already above-average price. We also aren’t huge fans of using the carrying case as a sort of kickstand to angle the panel towards the sun. Unlike other models with legs, this design saves a little weight but is far less stable and secure. Nevertheless, we found the all-weather efficiency and protections this panel offers impressive. If you prefer a sturdier waterproof option, check out the Renogy 100W Foldable. It is quite heavy, but the adjustable legs help keep it stable.

Seriously Solid and Very Efficient

Renogy 100W Foldable

REASONS TO BUY
Sturdy build
Very efficient charging in all conditions
Waterproof
Very stable, fully adjustable legs
REASONS TO AVOID
Often sold without a charging cable
Rather heavy
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 71.7 Wh
Power Output Rating (Watts) 100 W
Energy Generated in 1 Hour Indirect Sun 28.8 Wh
Measured Output in Direct Sun (Watts) 65 W
Measured Output in Direct Sun (Volts) 21.3 V

The Renogy 100W Foldable boasts a sturdy aluminum frame and legs, making it an impressively solid product. It’s just as rigid and sturdy as a panel you’d install on your house — but has a single hinge for transport. Compared to the many thin, slightly bendable solar chargers we’ve tested, this one feels just about bombproof. It also has seriously sturdy, fully adjustable angling legs that help it angle precisely into the sun no matter where it is in the sky (or behind the clouds). If that’s not enough, this panel put up some of the best energy efficiency results across all the models we tested, rain or shine.

Of course, this durability comes at a cost, and for the Renogy, that cost is portability. Weighing in at over 21 pounds, this is one of the heaviest portable solar panels we’ve tested. However, if you’re setting up a longer-term base camp, putting this hefty panel in place once and simply rotating it to follow the sun, this may not be a dealbreaker. If you want a solar charger that can withstand the test of time and the raging of the weather, this is the one for you. Those who prefer a lightweight option without sacrificing a waterproof design should check out the EcoFlow 110.

Best Solar Charger and Battery Pack Combo

Hiluckey HIS025 25000mAh Power Bank

REASONS TO BUY
Not expensive
Battery included
Easily carryable
REASONS TO AVOID
Lacks powerful solar generation
SPECIFICATIONS
Energy Generated in 1 Hour of Direct Sun 313 mAh
Power Output (Watts) 12 W
Energy Generated in 1 Hour Indirect Sun 182 mAh
# of USB A Outlets 2
# of USB C Outlets 1

The Hiluckey HIS025 25000mAh Power Bank is large capacity battery bank with a fold-out four panel solar array. When you need to transport this battery bank, it easily fits in any pocket. But when it’s time to put it in solar energy capture mode, you simply unfold the four-panel solar array and leave it in a sunny location. We’ve been testing a lot of integrated battery banks and solar panels over the years, and no other design works as well as the fold-out panel design used here. It works well on sunny days, and works better than many small panels on cloudy days as well. The battery has two USB-A ports as well as a USB-C port that’s fast-charge compatible. And like every good piece of outdoorsy tech, it has a light.

Though the Hiluckey is a more efficient solar panel than many other battery bank/solar panel combinations we’ve seen and tested over the years, it’s still not as efficient at converting sunlight into energy as any of the dedicated solar panels we review here. If you’re after the convenience of having one device that charges and recharges via solar, then this is a great option. However, you may also want to consider carrying a dedicated solar panel like the Big Blue SolarPowa 28 and a separate battery bank.

How We Test Solar Chargers

Since 2013, we’ve tested well over 100 different solar chargers and solar panels of varying sizes and capacities. We’ve used solar collectors of all shapes and sizes for everything from powering our laptops while overlanding to powering an electric bike. For this review, we compiled test results from all the most popular and most promising models currently available, all purchased at retail prices from many of the same popular merchants you likely shop at. Our teams tested and rated all these panels and chargers for different qualities depending on the type of panel and its intended use. We tested their charging speeds in direct sunlight and in overcast conditions, evaluated their portability, explored the bounds of their functionality, and pored over every detail. We hooked them up to portable power stations, our smartphones, laptops, and anything else that needed power. We camped, we hiked, we typed, and we loaded them into our vehicles and backpacks. In short, we put all these solar chargers through the wringer to find the best of the best.

Why Trust WebProCare

The test team for this review is led by Sam Schild with James Lucas contributing. Sam is an outdoor lover of adventure who has spent countless nights camping far, far away from the power grid. He’s an avid thru-hiker who has completed several long-distance trails and has crossed the country multiple times on bicycle. His first experience using a solar panel while camping was a small battery pack with an integrated solar panel that he used bike touring. Solar panels have come a long way since that fateful tour. When he’s not adventuring far and long, he’s often camping somewhere in Colorado or across the American Southwest, based out of his minivan, where his solar camping setup keeps all his technology charged so he can stay connected.

James spends hundreds of days outside every year documenting the outdoors and testing gear while traveling around his home in Boulder, Colorado, and where his heart is, in the Sierra. From working out of his van in the dispersed sun of the Rockies to base camping on top of sunny El Capitan in Yosemite, James uses solar panels from large to small to harness the sun and power his adventures, charging his camera gear and his connection to the world. WebProCare and James performed rigorous testing on all the models in the thorough portable solar charger review.

How To Choose the Best Solar Charger for You

Choosing the right solar device for your needs and intended use is very important. There’s a big difference between a massive unfolding set of solar panels for camping and a small, lightweight, portable solar charger for backpacking, and that difference is size and weight.

If you’re going to be carrying a solar panel on your back, you obviously want it to be small and lightweight. But if you’re going to load it into your car, weight isn’t as much of an issue. But the smaller the solar panel, the less energy it will produce, which translates to slower charging times.

There are also differences in useability between many solar chargers. Some models are easy to use and easy to set up, while others take a little more experience and maybe some head-scratching to start powering your devices. We’ll walk you through all the different types of non-permanent solar panels available to help you decide what’s best for you.

What Do You Want To Do With Your Solar Power?

Before choosing a solar charger, you should determine what you want to charge with it and where you want to take it. If you want to power a large power station for boondocking or powering your battery bank at base camp, you’ll want a larger, higher-watt solar panel. If you’re simply trying to keep your phone charged in the backcountry, you won’t need to buy as big of a panel because you don’t need as much wattage to charge small electronic devices like a smartphone.

We found that larger panels work better than the smaller ones we tested, so you’re often better off carrying a bigger one unless you seriously need to shed ounces.
Credit: Sam Schild

Portable Solar Chargers

The best portable solar chargers prioritize size, weight, and packability over all else. These smaller models are designed to charge electronic devices with lower energy needs, like cell phones and smartwatches. But if you’re trying to charge something that takes a lot of power, they won’t work as well. A portable solar panel generally has fewer solar cells, which translates to less power converted from sunlight to electrical energy or watts. The overall scores for each portable panel we tested are shown in the chart below.

Solar Panels For Camping

Solar panels for camping are generally larger than portable models. They also have a higher capacity to convert sunlight into energy. The chart below shows the overall score for each model we tested.

While many of these solar chargers are designed to be packed and unpacked to set up anywhere, they’re typically not portable enough to throw in your backpack with a tent and sleeping bag when you’re hitting the trail. However, solar panels for camping are portable enough to pack in the trunk of your car, truck, or van. They also usually include some way to carry them from your car to wherever you build your solar charging station. Still, they’re definitely heavier than you’d want to carry for long distances.

Solar Charger and Battery Bank

Some portable solar panels also have an integrated battery bank. These chargers are usually designed to be used more like a portable battery pack and less like a solar panel because the solar panel often isn’t big enough to reliably generate a lot of power from the sun. The panel will work in a pinch, but it can be slow to charge the integrated battery. You’re often better off charging a model with an integrated battery bank at home before your trip than using the panel to top off as you go if needed.

What Else to Look for in a Solar Charger

Once you’ve figured out the type of solar panel that will fit your needs, looking at specific features of different individual models will help you narrow down the field.

Solar Panel Size

Choosing the right solar charger size depends on how much space you have to store it and set it up. A bigger solar panel will generally have a higher watt output, which means you can convert more energy from the sun. And more energy from the sun means faster charging speeds for your devices. A smaller-sized solar panel will be easier to carry, though. If you will be backpacking with your charger, we recommend getting as small of a panel as possible that will still generate enough power for your needs. If you’re not going to carry your solar charger long distances, a larger size will generate more power for keeping more and larger electronics running while you’re out.

Solar Charger Watts

The number of watts that a solar panel can create correlates with its size. Generally speaking, more solar cells mean more watt output. Watt output is much like solar panel size, as you can see.

General Wattage Guidelines

Most solar chargers fall into these general watt ranges:

  • 1 watt to 10 watts: Most battery packs with an integrated solar panel. These are ideal for throwing in your backpack to charge your electronics while hiking and backpacking.
  • 10 watts to 20 watts: Most of the smallest solar panels without an integrated battery. These are best for charging small devices or a separate battery pack while hiking, backpacking, or traveling.
  • 20 watts to 30 watts: Many of the portable solar chargers we tested here fall into this wattage range. 20 to 30-watt chargers are great for faster charge speeds while still being relatively portable.
  • 30 watts to 50 watts: You’ll see even faster charging speeds in this range. These are ideal for charging multiple devices or larger electronics like laptops or tablets. However, some are a bit too bulky and heavy for most backpackers’ preferences.
  • 50 watts to 100 watts: Some of the largest-sized panels that don’t need to be permanently installed somewhere fit in this range. These larger-capacity panels are ideal for charging a large power station when camping or boondocking.
  • 100 watts or more: These are the largest solar chargers that you can still pack away to move. They’re the best energy-intensive devices and have fast charging speeds to keep your large battery banks or power stations full.

Direct Solar Charging Speed

Direct solar charging speed measures how quickly a solar panel will charge electronic devices. The primary purpose of a solar panel is to efficiently transform sunlight into usable energy. Therefore, we placed a lot of emphasis on direct solar charging speed in our testing. If a solar charger doesn’t perform optimally under direct sunlight, it might not even be worth using.

Indirect Solar Charging Speed

You don’t always have ideal blue skies and sunny days when using a solar panel, so we also tested how well a solar panel performs in cloudy conditions. Most solar panels don’t work as well in partial or indirect sun, but they still generate some power. Some panels are more efficient than others in indirect sun, so this is also worth considering when looking at solar chargers.

We tested indirect solar charging speed using a thin white sheet suspended above every panel. While this isn’t exactly the same as using them in cloudy conditions, we used this test to ensure we could reproduce the exact same conditions every time we test these solar chargers. During a cloudy hour in Colorado, we found that our test sheet actually prevented more solar energy from reaching the panels than during overcast conditions.

Portability

None of the solar panels we tested here are designed to be permanently mounted to a roof, so they’re all at least somewhat portable. But some chargers are certainly lighter and smaller than others. Small and light solar panels are more portable than big panels, but those bigger panels will generate more power than something more portable.

We considered the packed size and weight of every charger when testing portability. We also looked at other features, like carrying handles and protective cases, when testing portability. You’ll likely be transporting your solar charger often, so portability is key.

Functionality

Functionality measures how easy it is to use the charger. When testing functionality, we asked ourselves, “How user-friendly is this panel?

Functionality is a broad metric but an important one. We tested things like ease of setup, cable integration and storage, fold-out supports to angle the panel at the sun in the mornings or evenings, and anything else that makes a solar charger function well during real-world testing.

Multiple Device Charging

Many solar-powered devices can reliably charge more than one device at the same time. This is important if you’ll be sharing power among a group of people or have lots of tech to keep powered. Some solar chargers only have one power output, so they can’t charge multiple devices at once.

solar charger - many solar chargers have the capability to charge multiple devices...

Many chargers will charge multiple devices at once, but they’ll charge those devices slower than they’d charge a single item. If you need a lot of reliable power, multiple-device charging is something to consider. Remember, though, if you’re using a solar charger to charge a portable power station, that device likely has multiple device charging capabilities as well.
