The BigBlue 3 goes above and beyond the rest. Thanks to its impressive charging abilities and consistent performance across the board, this panel maintains its place at the top of the pack for another year. Though there may be other options that charge faster or look cooler, nothing beats this model regarding overall performance. When your electronics need a boost, this panel will deliver a consistent charge in variable conditions (from full sun to partially cloudy). In terms of features, we love the built-in ammeter. We also appreciate this panel’s simplicity and reasonable price tag. With three USB ports and a classic fold-out design, the BigBlue is an excellent all-arounder that efficiently charges most small gadgets.

One downside to this panel is its weight. Weighing in at 21.8 ounces, it’s heavy. As a result, it’s better suited for front-country use, though it will excel wherever you use it. Other than its weight, this panel receives high marks across the board.

When you’re outside in the sun, having a panel that charges quickly is key. The X-Dragon brought electricity to our devices. This 20W solar panel provides reliable charging at a fast speed and a reasonable price. The high conversion rate made the panel efficiently charge on pretty sunny days and when there were dark cloudy skies. Each of the X-Dragon’s posts can generate up to three amps, providing an extraordinary amount of charge for any USB device.

Roughly the size of a notebook, this solar panel unfolds its three panels to capture an impressive amount of sunlight. The X-Dragon had a solid conversion rate, transferring a lot of sun into charges. Anyone looking for a backpacking solar panel, a place to charge while at basecamp, or just some extra energy in the sun should check out this affordable, strong solar panel.

Hard to replenish battery via solar

The OEUUDD 25000mAh battery pack is a high-capacity battery with three USB ports that deliver rapid charge to small electronics. We love that it has a large capacity and can charge a phone multiple times when the battery is topped off. The small solar panel works well enough for the battery to replenish using solar, though it takes longer than traditional panels. In addition to all these great features, the OEUUDD 25,000mAH rings in as one of the most reasonably priced options for solar charger setups.

Our issues with this battery pack are similar to our problems with other battery packs/solar options — patience is required. This product does not work that well as a solar charger alone; it will take a few full days to charge the panel fully from the sun. That said, the panel will continue to trickle charge the battery pack, even when small electronics are plugged in, which is a feature that we appreciate. We recommend also considering a top portable charger and pair it with a panel.

In our Best Solar Panels for Camping review, which looks at larger panels, the Jackery SolarSaga 100 was both the best overall and the best value. This 100-watt solar panel is significantly more affordable than its competitors, user-friendly, lightweight, and performs well in full and partial sunlight. It is the most efficient in rapidly charging electronic gadgets of any panel we evaluated, regardless of outside weather. The SolarSaga instantly folds into a compact size and weighs only ten pounds which is light compared to similar wattage panels. The straightforward fold-in-half construction makes it very easy to transport it in your vehicle for your next camping trip. The handle makes it easy to transport throughout the campground. You can swiftly deploy its fold-out legs to position it squarely at the sun and get the most out of its rays in the morning and evening. It has USB-A and USB-C ports and a DC output to connect directly to devices or an external battery. A built-in pouch with a zipper on the device’s rear provides convenient storage for the hardwired DC charging cable and USB ports. It’s a wonderful addition to your solar camping setup or if you want to have an off-grid backpack.

Although light and folds into a small footprint, the SolarSaga 100 only has a single fold in its design. Because of this, its folded size is significantly larger than some of the other panels we examined. This is your panel if you want a high-watt solar panel that offers excellent overall value for your upcoming camping trip.

Why You Should Trust Us

We put this comprehensive review together after researching over 80 different products on the market. After careful researching, we selected and bought the best of the best. Then, we tested each product objectively and thoroughly. We look at how quickly each model charges with different amounts of sunlight, how it handles multiple devices at once, the rate of charging, and its portability and durability. To test our metrics, we used each contender in the field. Our process reflects the most up-to-date products, with updates occurring multiple times per year.

Our solar charger testing is divided across four different metrics:

• Direct Solar Charging Speed (35% of overall score weighting)

• Indirect Solar Charging Speed (35% weighting)

• Portability (15% weighting)

• Multiple Device Charging (15% weighting)

This review is headed up by James Lucas, a long-time writer, editor, and photographer. As an avid climber who authored the Yosemite Valley Bouldering guidebook, 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. OutdoorGearLab and James performed rigorous testing on all the models in this thorough review.

Analysis and Test Results

Now more than ever, solar technology is growing in popularity. In this updated review, we’ve tested a wide variety of portable models. Our current line-up includes small panels with built-in battery packs to massive 50W behemoths. By spending time testing these solar panels on the road, we get to see firsthand the latest and greatest #vanlife solar setups. After looking over several options, we rated each on four important metrics: direct solar charging, indirect solar charging, multiple device charging, and portability. Whether you are looking for a solar setup for car camping or a compact charger to power your iPhone while on a backpacking trip, our review offers excellent recommendations for anybody.

Dozens of companies produce affordable, effective monocrystalline panels ranging from small 5W models to more substantial, powerful options that will allow for a faster charge. These monocrystalline models are much more effective and lightweight than their polycrystalline forefathers. We tested a few small wattage models that were portable and lightweight. The OEUUDD 25000mAh has a larger capacity battery and a 5W panel. While it doesn’t function as well as some of the larger solar panels, its ability to charge our devices made it a force to be reckoned with.

Credit: Jane Jackson

We filled out the upper end of the wattage range with the addition of the Anker 21, the SunJack 25, and the Ryno-Tuff. We added the BigBlue 3 and the Goal Zero Nomad 50 on the far upper end of the spectrum. In general, solar technology is improving, and most panels performed fairly well. That said, it’s important to note that in this review, the panels’ metric ratings range in scores, mostly due to their output capabilities (i.e., wattage), rather than the design of the models themselves.

Just as was the case in past reviews, panels with large-capacity battery packs and small-capacity solar panels tend to charge our electronics quickly but take eons to charge via the sun. With this style of charger, we recommend topping off your battery pack at home before bringing it into the field.

The Goal Zero Nomad 20 and the Goal Zero Nomad 50 are capable of charging laptops.

We looked at each solar panel’s durability as well. By design, portable solar panels need to be able to withstand long exposure to the elements. The way to get ample charge to small electronics is by leaving the panels exposed to the sun for long periods. To ensure these panels are up to the task, we have tested them in all kinds of conditions — from the baking desert sun to high alpine terrain to extreme wind and rain. In general, almost all the panels stood up to the challenge. The canvas protective fabric is like an exoskeleton guarding the important insides of the panels. Solar technology seems to be advancing too, with companies working to make cells more durable and resistant to sun and water damage.

During our testing, we also checked out each panel’s accessories. Panels that don’t come with a built-in battery are often paired with a top-quality portable external battery pack. This arrangement allows the panel to charge the battery during the day while you’re using your devices, and you can charge your device at night via the external battery. External batteries are an essential addition to any portable charging kit. Most modern tablets and smartphones demand higher power (like 2A charging ports), and this becomes harder to produce from the sun (which is variable at best). Instead of bulking up the solar panels themselves and making them too cumbersome to use, we found it much more effective to simply charge external batteries on a rotating system to keep a constant stockpile of fully charged battery packs ready to go. That way, you have a lighter-weight solar charger that charges a high-quality external battery. This battery can, in turn, produce the necessary 2A of current to charge small devices. Overall, we generally prefer going with a top quality panel paired with a great battery rather than choosing a battery with an integrated panel.

Value

Unlike some other products we test here at OutdoorGearLab (we’ve tested bikes that cost more than our cars!), portable solar chargers tend to be on the affordable end of the outdoor gear spectrum. However, even with such a reasonable price point, some models had much better value than others. For example, the reasonably priced OEUUDD 25000mAh performed exceptionally well across the board, even standing up to some of the more expensive, higher capacity models like the Goal Zero Nomad 50. Other models cost a pretty penny and did not compare to the high scorers in our side-by-side tests. To determine the value of the products we gauged the ability to charge, the portability, and how many devices the panel could charge against the price. This metric often comes down to being the most important as it determines the actual worthiness of the product.

Direct Solar Charging Speed

The main use for a portable solar panel is charging a device when electricity is not readily available. We took this into account when we weighted direct solar charging speed as one of our two highest rating testing metric. We used our lead tester’s personal cell phone to execute this experiment — a Google Pixel 3. We timed each panel as it charged our phone and also used a standard small-capacity battery pack to cross-reference our results. It should be noted that in previous iterations of this test, we used an iPhone 6, which is also reflected.

We set each one in full sun for thirty minutes to test the panels and noted how much charge the phone received. This way, we could obtain a good read on how efficiently the individual models worked over extended periods. We also timed how long it took each one to charge our 10,000 mAh portable battery packs, so we also had that data to compare. In general, this size battery can charge an iPhone from 0 to 100% about two times.

We found a broad range in the ability to charge batteries. This considerable variability is due to the extensive range in output power of the contenders we tested. Twenty-one watts is four times as powerful as a 5W device, so it makes sense that panels like the BigBlue 3 earned one of the highest in our testing. The Ryno-Tuff 21W also impressed us in this metric, especially considering its humble 21-watt capacity. This panel charged our phone 34% over the course of a 30 minute period.

Using this USB multimeter, we found that the measured output was often less than what the manufacturers’ claimed.

Credit: Jane Jackson

The main function of a solar charger is to charge electronics efficiently. Therefore, we recommend investing in a higher wattage charger to facilitate this function. For speed and efficiency, a more effective watt option is more efficient. That is unless you’re trying to save weight or money, in which case a less powerful model might be a good compromise. With that in mind, it’s no surprise that some of our highest scoring panels in this metric were panels with the largest capacity.

Indirect Solar Charging Speed

Here we consider the following questions: is your panel going to quit on you just because one cloud passes overhead, as you left it out on what appeared to be a clear afternoon? Or is the solar model strapped to your backpack, causing your phone to constantly vibrate as the connection goes in and out of the USB port? These are the questions we addressed in our charge interruption recovery metric. We measured the amount each model charged within a half-hour span to test this criterion, first in full shade and then again in intermittent sun and shade.

The highest performing models in this category were the ones with a large capacity (15-20W or higher) or a built-in external battery. Though small battery/panel combos, like the OEUUDD 25000mAh, can manage shade — since it continues to charge your device off the battery — the panels themselves are too small to receive substantial power from the sun. The panel capacity of these models means their solar production provides a backup as opposed to a primary power source.

Compared to the BigBlue, the Falcon has a larger surface area with solar cells, improving its performance in this metric.

Credit: Jane Jackson

Those with a larger surface area also tended to do better in this metric because there are more cells exposed to the sun at one time. The BigBlue 3, which has lots of surface area, comes with a built-in auto-restart function. This feature allows the panel to reconnect to your device after being shaded automatically. Naturally, the unit will still charge slower in cloudy conditions. The auto-restart feature will help to continue the flow of power in less-than-ideal charging conditions. It also helps avoid the constant vibrating that happens when a phone is continually reconnecting to a panel.

These are the types of conditions we wish for when charging electronics using solar power.

Credit: Jane Jackson

Multiple Device Charging Speed

As you might guess, when tasked with the challenge of charging multiple devices at once, the more powerful models performed better than lower wattage models. Smaller panels such as the 5W and 7W models don’t have the power to sustain two gadgets at once. If this is a priority for you, then select a panel with a higher wattage. Generally, our testing found lower watt models to be less capable in this metric than the higher watt devices that can charge two devices.

The BigBlue 3, Anker 21, and SunJack were high scorers, as was the OEUUDD 25000mAh. As discussed above, the results show that models with higher wattage are more effective at charging multiple devices at once. We were impressed by the SunJack’s overall power and efficiency in this metric. Panels with built-in battery packs also excel in this metric, with the Goertek holding its own.

Both the ECEEN (previously tested) and the Blavor impressed us with their burly designs.

Credit: Jane Jackson

Portability

Since an essential function of many of these panels is to remain portable, this is a crucial category. A too heavy or bulky model will be left behind to collect dust in the closet rather than accompany you on your next adventure.

The panels that cleaned up in this metric in terms of weight were the Dizaul 5000mAh Portableand the Blavor Qi 10,000mAh. These models are the latest in battery-pack/solar charger combos, and we were impressed to see manufacturers getting this design into such a compact shape and size. These two panels weigh 4.8 ounces and 9.3 ounces, respectively.

Small panels, like the BEARTWO, are easy to throw into a bag without much thought about weight or size.

Credit: Jane Jackson

Others come with lots of accessories and extra features, which make them more exciting to use but also make them bulky and unappealing to carry on long trips. There is a happy medium between overkill and overly simple, which of course, depends on your preference and needs.

The Falcon is definitely one of the largest panels we’ve used in a while.

Credit: Jane Jackson

While portability is a critical consideration, we placed more emphasis on performance. If the panel doesn’t work, then it is just training weight. That was our reasoning behind handing out awards to larger panels like the BigBlue 3.

Conclusion

Deciding on the right solar charger can be an overwhelming task. To make it easier to wrap your head around, you’ll want to figure out what you will be using it for and go from there. Are you running a mobile office and need to keep multiple, energy-hungry devices happy? Or are you concerned with having a fully charged phone on a weekend excursion?

The smaller watt options are going to be less expensive and often less powerful. As you increase the wattage, the panels typically become more efficient. The sky is the limit, but it depends on how much money you are willing to spend. We narrowed in on the top competitors and put them to the test. Some perform better than others, and a higher price tag doesn’t necessarily mean a better product. We hope that our thorough tests and reviews of these products will be useful to you as you shop around for your new solar charger.

PORTABLE CHARGING & POWER BANK BUYING GUIDE

How to charge anywhere.

Mobile devices like smartphones and tablets make life so much easier. That is, until they run out of battery power when there’s nowhere to plug in.

The answer is a portable charger.

A lightweight power bank or mobile battery pack that you can carry anywhere.

They go under different names: battery packs, power banks, portable chargers, fuel banks, pocket power cells and back-up charging devices to name just a few.

But whatever you call them, they all do the same thing.

Charge your phone or tablet without needing a power outlet.

Simply charge it up at home, throw it in your bag or your pocket, and connect it to your phone whenever it needs a quick battery boost.

You’ll never suffer from “low battery anxiety” again.

Charge anywhere.

Make sure you’re always connected with back up battery power that’s as mobile as you are.

Battery packs come in all shapes and sizes, smaller sizes for an essential smartphone boost in your pocket, or bigger sizes for multiple charges or to charge a tablet.

Choose one with cables included, or one with multiple ports to charge more than one device at a time.

Pick out a power fortress or something small and sleek, and take the power to charge anywhere, with you everywhere.

HOW TO CHOOSE YOUR PERFECT
BATTERY PACK

SIZE & POWER

Start by choosing the size of your battery (aka power bank).

This is not just about which one will fit in your pocket or your purse. The size of the battery is about the power inside. Most batteries will feature a number on the front that tells you the number of mAh or “milliamp-hours.”

Common sizes range from 2000mAh up to 10,000 or even 12,000 mAh. Bigger numbers mean more power, which means more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.

Explore Battery Packs

5,000mAh

Charges an iPhone 7 (running iOS 10) up to 1.5 times on a single charge in internal testing.

10,000mAh

Charges an iPhone 7 (running iOS 10) up to 3 times on a single charge in internal testing.

15,000mAh

Charges an iPhone 7 (running iOS 10) up to 5 times on a single charge in internal testing

We’ve used smartphones and tablets to compare battery sizes, but most battery packs will charge any device that charges via USB, such as a GoPro camera, Kindle reader or Bluetooth headset. Bigger devices that draw more power will need bigger batteries – more mAh – to charge them fully.

POWER OUTPUT

How to ensure fast charging for your phone/tablet.

Technically the standard USB port on your battery pack (aka power bank) will fit any standard USB cable. However, the amount of power it can provide may vary.

Explore Battery Packs

4.8 AMP / 24WATT (shared*)				This has the power to charge 2 tablets simultaneously at the fastest possible speed.

* “Shared” is the combined power available on multi-port power banks, and is
different from “total power”. Learn more >

CABLES

WHY CABLES MATTER

The quality of your cable can help to determine how quickly your power bank (aka portable charger) and attached devices power up. Higher quality cables also protect your devices from overheating and harmful power surges.

A CABLE TO CHARGE THE POWER BANK

Every power bank (aka portable charger) needs to be charged. This usually requires a standard USB to Micro-USB cable. Simply connect your power bank input port (usually Micro-USB) to a standard USB wall charger.

A CABLE TO CHARGE YOUR PHONE, TABLET, WEARABLE, OR OTHER DEVICE

Most power banks (aka portable chargers) charge via a USB port, simply connect your device to the USB port and begin charging. Some power banks come with a cable, or a variety of cables, that are detachable. This makes it easy to switch between cables for your iPad, your Samsung phone, or other device. Other power banks have a cable hard-wired to the pack. This prevents losing the cable, but makes the power bank less versatile overall.

CHARGING THE BATTERY PACK

There is no such thing as a magic battery pack.

Unfortunately, no battery pack has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge.

If you need one immediately, check on the package if it’s ready to use when you buy it. Some will need to be charged at home before they can be used.

To charge, plug the supplied cable into the input port on the battery pack. Attach the other end, usually a standard USB, into a wall charger or other power source.

Battery pack input ranges from 1Amp up to 2.4Amps. Put simply, the bigger the input number, the faster it will recharge. Most wall chargers deliver up to 2.4Amps, but it’s worth checking the charger if you’re in a hurry, as a 1Amp charger might take twice as long.

Some battery packs have an LED indicator, which tells you how much power the battery pack has left. This will tell you when you need to recharge the battery.

WITH GREAT POWER…

A power bank (aka portable charger) seems like a good idea. But is it safe?

Some power banks are carefully designed and rigorously tested to offer complete peace of mind, that is backed up by robust warranties and guarantees. Some warranties protect the power bank itself, while others also safeguard the electronic devices you attach to it, like your phone, tablet or smartwatch.

Some batteries might not offer such peace of mind. Opting for low cost or counterfeit products can turn out to be expensive, even dangerous. It’s easy to avoid this by following these simple steps.

REGISTER YOUR DEVICE

Some power banks (aka portable chargers) require you to register your purchase, by providing the serial number either online or via a helpline. This is a good way to activate your returns policy and ensure your product is not a counterfeit.

CHECK THE WARRANTY

Manufacturer, country of origin and the type of power bank may mean differences in the types of warranties and what they will cover

Warranties

LIMITED WARRANTY

Covers the power bank (aka portable charger) for a specific period from the date of purchase, and usually requires you to keep your receipt to prove purchase date.

LIMITED LIFETIME WARRANTY

Covers the power bank (aka portable charger) for the reasonable life expectancy of the product, which may vary according to manufacturer.

CONNECTED EQUIPMENT WARRANTY

A more robust warranty which not only covers the power bank (aka portable charger) itself, but will also offer to repair or replace devices that are damaged while “properly connected” to the power bank, in line with manufacturer guidelines. Such warranties usually have a clause stating up, “up to $1,000” or similar. The amount should be enough to cover the types of device recommended for use with the power bank, such as a smartphone or tablet.

THE IMPORTANCE OF QUALITY

A robust quality assurance offers durability and peace of mind.

Rigorous testing and thorough investigation of product performance make your battery pack more likely to last longer, and less likely to harm you and your valuable electronics.

Safe battery packs should have undergone the following testing

Efficiency

More efficient battery packs will have a lower operating temperature, which wastes less energy, giving it longer life expectancy.

Over Current Protection

OCP prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.

OVER VOLTAGE PROTECTION

Like OCP, OVP protects both the battery pack and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection

High-performing batteries should not be overcharged or fully discharged to prolong their life expectancy. Some battery packs consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures

While using batteries in extreme temperatures isn’t advised anywhere, it can be a good indicator of weaknesses in design and construction. Batteries which pass such stringent testing will be more durable and offer improved assurances of overall safety and performance.

CERTIFICATION

Compliance with legal standards of safety.

These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.

To learn more, please see CHARGE ANYWHERE above, or The Cheat Sheet below.

Cheat Sheet

mAh
mAh stands for Milliamp Hours and quantifies the energy storage capacity. It is based on how long a battery will last when power is drawn constantly, e.g. a 2000 mAh battery will power a device drawing 100 mAh for 20 hours.

Amps
Short for ampere, this is a unit of current, not a unit of charge. It describes the constant and average current that passes through the circuit.

Shared vs. Total
Shared power banks will provide power where it’s needed, e.g. a 2 x 1.7A [3.4A shared] will charge two smartphones at 1.2A each, or one tablet at 2.4A. Some multi-port power banks (aka portable chargers) will have fixed outputs on each port, e.g. a 2 x 1.2A [2.4A total] and will charge two smartphones at 1. 2A. This is what is referred to as, “total” power.

Smartphone
A mobile phone with an advanced mobile operating system, usually with internet access, touchscreen interfaces, cameras, media players and the ability to run third-party apps.

Tablet
A mobile computer with a touchscreen display, circuitry and battery in a single, portable device, usually featuring pop-up, virtual keyboards for typing.

USB port
Short for Universal Serial Bus port, a USB port is designed for use with an industry standard connector to communicate data and supply electric power between devices.

Standard USB—Also known as USB-A
The most common, universal connector on the “other end” of most current USB cables, is a USB-A. These are often suitable for use with computers, car chargers, wall chargers, and many other devices.

Micro-USB
Micro USB is a USB connector that is smaller than USB-A, and is often found on smaller or thinner mobile devices, such as android smartphones, digital cameras, battery pack input ports, Kindle readers and many others.

USB-C—Also known as Type-C
USB-C is a new type of USB connector, hailed as the new standard. Smaller, faster and more user-friendly than previous USB types, USB-C has widespread support from industry leaders, meaning that USB-C will come to replace all other USB types.

Lightning
A connector developed by Apple to replace the 30-pin connector. Used across all iPhone, iPod and iPad releases since iPhone 5, iPod Touch (5th generation) and iPad 4th generation.

Optimal Charging
The fastest possible charging for the connected device is optimal charging. Larger devices require more power, so a charger with limited output may still power up, but will take longer to fully charge
