The Best Power Banks of 2023, Tested and Reviewed
If I have the choice between a device that uses conventional batteries or one that uses rechargeable batteries, I’ll always go with rechargeable. But that means I need to maintain that device, which is why a portable power bank comes with me on nearly every trip. Over the past month, I’ve tested a dozen of the top rated power banks, and from that initial pool, I’ve narrowed it down to the six best power banks.
It doesn’t matter if I’m spending time outdoors or traveling, I’ll need to recharge something, and will inevitably use a power bank. My picks for the best power banks have been used while in the outdoors as well as for everyday use and holiday travel. They’ve juiced up headlamps, GoPros, my iPhone, and even other power banks. After all that field testing, here are my findings and recommendations for the best power banks.
- Best Overall:Anker PowerCore Slim 10,000 mAh
- Best Solar:BigBlue 28-Watt Solar Charger
- Best for Fishing:Anker Solar
- Best Small:Goal Zero Flip 12
- Best for Backpacking:Anker PowerCore Essential 20,000 mAh
- Best for iPhones:Anker Powercore Magnetic 5K
How I Tested the Power Banks
I tested the power banks in three ways: First, I timed how long it takes them to fully charge and how many times they fully charged my iPhone 11 Max. Then over a one-month period I carried these portable chargers during outdoor activities in several states, on long road trips, and a fishing trip in North Carolina. During that month I subjected them to heat, cold, and water to test their durability. Finally, I weighed and measured each power bank to provide you with accurate specs.
Here are the attributes I used to evaluate the power banks:
- As advertised (Do the chargers do what the manufacturer advertises?)
- Number of charges and charge time (How many times does it charge a phone? How long does it take to charge?)
- Use in the field (Is it practical to use while hunting, fishing, camping, hiking or backpacking?)
- Durability (Can it hold up to abuse?)
- Weight (Ounces are pounds, and pounds are pain.)

Product Overview
If you’re looking for an all-around solution, consider the PowerCore 10,000 mAh. It’s a happy medium between a small charger like the Goal Zero Flip 12 and the PowerCore 20,000 mAh. If you are going out for the day or an overnight trip, it provides plenty of juice with two phone charges. It’s also light and small enough to not take up space in a pack or
The Anker PowerCore went through three key tests: a timed charge, testing how many times it would charge my iPhone 11 Pro Max, and using the power bank in the field. One of my favorite features of this power bank is how fast it charges. In a few hours, you can bring it from dead to fully juiced and ready to hit the field. It’s fast charging ability also makes it an excellent candidate to pair with a solar panel like the BigBlue 24 watt.
In my testing, the Anker PowerCore charged my phone twice. That’s two times with the phone on and in use. So, if you keep your phone off while it’s charging, you can expect the power bank to last longer—Anker rates it at two-and-a-quarter iPhone 12 charges. I most often use this charger when I’m going to be out all day and will need to charge my phone once, along with another device like a GoPro. It would also be ideal for a two-to.three day camping trip where you need to charge your phone twice.
The Anker PowerCore is slim and light enough that you can carry it in a for everyday carry. It’s also perfect for carrying in a daypack or sling bag. Mine has been with me hunting, fishing, and traveling—it’s yet to let me down.
Best Solar: BigBlue 28-Watt Solar Charger
Key Features
- 25 Watt
- 3 USB ports
- Charges a phone in about 3 hours of full sun
- Charges a 10,000 mAh power bank in 6 hours
- Weight: 1 pound 9 ounces
- Length: 11.125 inches
- Width: 6 inches
- Depth: 1.375 inches
- Size
Product Overview
There are a lot of portable solar chargers on the market, and they range in price as much as they do in effectiveness. The BigBlue is the best solar power charger that actually works and it’s affordable. You have to manage your expectations when it comes to these small solar panels and while three hours to bring a phone to full charge seems like a lot, I think it’s pretty impressive.
Here’s the context of my testing. I tested this solar panel in the fall when the sun sits low in the sky. The first hour of the charge the panel received partial sun. I managed the position of the panel throughout the day to keep it aligned with the sun.
The first test was to see how long it took to charge a Goal Zero Flip 12, which is good for one full phone charge. That test took three hours, which is how long it takes to charge the Flip 12 when plugged into the wall. The next test was to see how long it takes to charge my pick for the best power bank, the PowerCore 10,000 mAh. After six hours in the sun the power bank was at full power.
When you’re in the field, you probably don’t have time to sit around for six hours waiting for a power bank to charge. But, that’s not the best way to use this charger. In my opinion, using the solar panel to maintain battery life rather than fully charge a device is the best use. For example, if you are glassing in the morning, you can roll out your solar charger and plug in a device. Let’s say you stay put for just an hour, that’s enough time to charge a phone 30 percent. By charging your devices a little at a time throughout your time in the field you can make your powerbank or batteries last much longer.

Product Description
I used the Anker Solar on a few upland bird hunting trips and a trip chasing false albacore in North Carolina making this the best power bank for fishing. While chasing albies, we had one bad weather day with a lot of chop. If I wasn’t wearing a rain suit, I would have been drenched. The Anker Solar was subjected to the same salt spray and it handled it just fine. It also had plenty of power to keep my phone, and GoPros fully charged during the ten hours of fishing. After I got off the boat, I grabbed a quick dinner before heading out on kayaks for fishing dock lights at night. That few hours wasn’t enough time to get the Anker Solar back to even half charge, which is the main downside.
If you plan to use this charger for backpacking or hunting, the weight and bulk are something to consider. The Anker PowerCore 20,000 mAh is considerably lighter and smaller, but it lacks the solar charging and weather protection the Anker Solar offers. Personally, I’d rather take the PowerCore for those applications, and think the Solar shines for fishing applications.
One of the questions you probably have is: does the solar panel on this powerbank work? If you plan to use the solar panel to fully charge your power bank, you’ll be waiting a while. I tested the solar charging capabilities by placing the power bank in full sun for six hours and did not see a measurable difference in charge. However, I think if you keep this charger in the sun all day, the battery will last longer than if you didn’t have the solar panel. So, consider it more of a battery extender, rather than a charger like the BigBlue.
Best Small: Goal Zero Flip 12
Key Features
- 3,350 mAh
- One USB port
- One full phone charge
- Three-hour charge time
- Weight: 2.6 ounces

Why it Made the Cut
This power bank weighs nothing, has a small footprint, and has enough juice to completely charge your phone.
Product Description
This Goal Zero small power bank won’t take up space in your pack and has enough juice to bring your phone from dead to fully charged. For overnight or day trips, it’s my top choice. I also like keeping this best small charger in my carry-on to keep my phone charged while traveling.
The biggest con is that its square shape makes it uncomfortable to carry in a front But, it’s at home in a cargo. fanny pack, or day pack. My favorite features of the Flip 12 are it charges quickly and it doesn’t need a charging cable—the USB is built in. I also think it’s a great companion to a solar panel like the BigBlue.
Best for Backpacking: Anker PowerCore Essential 20,000 mAh
Key Features
- 20,000 mAh
- Up to five phone charges
- USB-C and Micro USB input
- Two USB output ports
- 11 hours to fully charge the power bank
- Weight: 12 ounces
- Length: 6.25 inches
- Width: 2.875 inches
- Depth:.5 inch
Product Description
This is a power house for charging devices. Whether you’re on a short trip where you need to charge a bunch of devices or a long trip where you need to just keep a phone juiced, this is the best power bank. It weighs less than a pound and it’s easy to carry thanks to its slim profile and beveled corners.
The biggest con of the 20,000 mAh PowerCore is it takes a long time to fully charge. But, the negatives end there. The two USB ports allow you to simultaneously charge two devices. I used it to charge my phone and headlamp each night during a weekend outing. During a November fishing trip, I left the 20,000 mAh PowerCore outside in freezing temperatures. The power bank didn’t lose a bit of charge, which has been my experience with all my Anker power banks in cold weather. Granted, my cold weather in Virginia is different from Fairbanks, Alaska’s cold weather.
Best for iPhones: Anker Powercore Magnetic 5K
Key Features
- Wireless charging
- USC-C output and input
- 5,000 mAh
- Charges in three hours
- Charges a phone once
- Magnetic charging works with iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max
- Weight: 4.6 ounces
- Length: 3.625 inches
- Width: 2.437 inches
- Depth:.625 inch
Product Description
The PowerCore Magnetic 5K is a great size for everyday carry. It’s super lightweight and charges a phone fast using a USB-C charger. But, don’t buy this charger unless you have an iPhone, preferably a 12 variant, and a compatible magnetic case. If you don’t have a compatible magnetic case, you’ll have to remove your case to use the magnetic feature and you’ll be disappointed in the strength of the magnet.
But, if you do invest in a magnetic case, it’s a great wireless charger for outdoors use. Other wireless chargers aren’t practical for outdoor use because they need to be laid flat to maintain contact with your phone. But, the magnetic power bank from Anker snaps to your phone and stays connected even in a cargo or your best backpack. You get the benefit of not needing to bring a charging cable and a continuous charge while you use your phone. I find this charger is ideal for all day sits, or days when I’m running OnX continuously.
How to Choose a Power Bank
Power banks are a lot like other outdoor gear, there’s a trade off between features and weight. You can get more capability, but you’ll pay for it in size and weight. You’ll have to decide how much capability you need and how much weight you’re willing to carry.
Here are more things you’ll need to consider when buying a power bank or solar charger.
What is a mAh and how much do I need?
A spec you’ll often see is mAh, which stands for milliamps hour. The mAh spec is a measurement of power over time, the higher the mAh the more power the battery contains. To fully charge a phone you’ll need 3,000 to 5,000 mAh.
Watts
A watt is a measurement of rate of energy transfer. So, when shopping for portable solar chargers keep in mind that the more wattage the more power the panel can provide. I’d recommend at least a 24-watt solar charger.
Are solar chargers practical?
If you’re in an area where you can provide a solar charger full sun, and leave it all day to charge a power bank or device, they are practical. But, you can’t expect a solar charger that fits in your to work well because you need surface area to effectively charge.
I found small solar panels to work best for maintaining battery life, rather than being used to fully charge a device. The main issue is that portable solar panels are small, and can only gather so much electricity. What they can do is lengthen your phone or power bank’s life. When you stop to glass or cook lunch, lay out your panel and let it charge the device for a few hours. Even if it’s a few percent increase in battery life, it’s free energy and a few percent here and there can add up over a week’s trip. If you get an extra 25 percent out of our powerbank I count that as a win.
Solar panels are also bulky and heavy. For example, the BigBlue weighs 1.5 pounds, and the 20,000 mAh PowerCore weighs less than a pound. You can pack two 20,000 mAh charges that would charge a phone ten times total and weigh the same as a BigBlue.
Waterproof power banks
Why didn’t I include any waterproof power banks? The rugged power banks that are fully waterproof and shock resistant come at the penalty of being heavy and bulky for the amount of power they provide. I’d much rather drop my power bank in a dry bag than carry the extra weight of a waterproof power bank. It’s also worth pointing out that while your waterproof power bank might survive a submersion, your phone won’t.
FAQs
Q: Which capacity of power bank is best?
A 10,000 mAh power bank is a good balance between charging ability (two phone charges) and size.
Q: Which brand power bank is best?
Anker makes the best power banks for everyday use. Goal Zero makes great power banks specific for the outdoors.

The 5 Best Solar Powered Chargers for Your Phone or Tablet
We all know the sudden drama that happens during our outside pursuits when we see a “low battery” warning on our phone, tablet, digital camera or other device. Outdoors you’ll find yourself many times far from any power outlet to recharge your devices.
What will you do then? Have you ever considered carrying with you a solar powered cell phone charger?
Whether you’re on a camping trip, mountain biking, traveling the world or just walking around town a portable solar charger can help keep your devices powered up anywhere under the sun.
The idea of portable solar gear that uses free off-grid solar energy to power up our mobile lifestyle is pretty amazing. It’s surely one of the best inventions of this century.
Solar battery chargers come in many different shapes, sizes and efficiency ratings. We’ve done the hard work already and picked the top five solar powered chargers available right now for sale on Amazon that have the latest photovoltaic (PV) technology and the best charging performance.
We have also included a buyer’s guide at the end of the article where you’ll find everything you need to know about choosing the best solar charger, so make sure to check that out as well.
Best Overall: BigBlue 24W Solar Powered Charger
The BigBlue 3 USB ports 24 Watts solar charger is our top pick for the best solar phone battery charger to buy in 2022 because it offers a remarkable combination of manufacturing quality, price, portability, and charging speed.
It features highly efficient energy conversion SUNPOWER solar cells (up to 23 percent efficiency) and SmartIC technology, which means that this charger will automatically recognize the charging protocol of your devices so that it can deliver the most suitable and fastest charge possible. Three USB ports allow you to plug in and split the current between 3 devices at once.
What makes BigBlue the best portable solar charger for almost any kind of environment is also its charging performance in diverse weather conditions. This charger delivers a steady energy flow even on cloudy days so you can confidently plan your outdoor activities without having to worry about low battery devices.
The BigBlue solar panels delivers 24 Watts under direct sunlight and it charged our iPhone 11 from zero to full in about two hours. During cloudy days the charging capacity varies according to the Cloud exposure, but it should be able to charge anywhere from 20 percent and above which will be very useful especially in emergency situations.
This solar charger is made of four SunPower solar panels sewn into a durable canvas and a fifth section that’s more like a small pouch for storing your iPhone or Android phone while charging and thus protecting them from the direct sun exposure and overheating – however, if you have a cable long enough, it’s always better to move your devices into the shade. You can also easily store all the cables in this department.
Inside the pouch there are three USB ports that deliver up to 2.4A per port or 5V/4A overall (depending on how much direct sunlight hits the solar panels), and a small LED that indicates when there is power flowing from the panels.
What about portability? The BigBlue solar powered charger weighs 754 grams or 26.6 ounces and the entire solar charger folds up to about 14 millimeters or 0.55 inches thick. This makes it perfect to carry around when traveling, backpacking, going to work, or school.
To get the most out of your portable solar gear, we highly recommend pairing the BigBlue charger with a USB battery pack. For example, the Anker PowerCore Elite 20,000 mAh power bank is fully compatible with the BigBlue 24W solar charger and it can store enough energy to charge an iPhone 11 from zero to full six times. A portable battery pack like this one is a must-have since the solar chargers themselves cannot store energy and provide it during night time when the sun is not around. With a charged power bank, you are powered up 24/7.
What we like:
- Great value for the price
- The SmartIC technology
- Amazing charging speed
- Three USB ports
- High quality material
- Very compacted when folded
What we don’t like:
- Removable USB hub would make packing better
- A charging cable for iOS devices could be included
The Lightest and Most Flexible: Portable Solar Panel Sunslice Fusion Flex 12
Sunslice Fusion Flex 12 Watts with two USB ports (5V) each with max output of 2.4A is a perfect option for those who like to FOCUS on their outdoor experience without worrying about maintenance of the devices they bring along.
Two portable solar panels are extremely lightweight (just 270 grams/9.5 ounces) and easy to fold into a thin A4 like shape. That’s it, you can head out now! Then you just open the pack for solar cells to face the sun and use right away on the go by plugging in your USB devices like a smartphone and/or tablet. Additional plus are two elastic fasteners and two carabiners you receive with the product to easily attach the charger to your backpack.
The solar panel is made off CIGS thin film solar cells, which are a versatile option when it comes to application and practical use of photovoltaic technology. The thin film is flexible, you do not have to worry about bending the panels to fit better in your backpack. According to the manufacturer, the solar cells reach up to 16.5% efficiency in the perfect sunny conditions. Thin film solar cells perform better than crystalline solar cells when exposed to the strong summer sun, they maintain better power production when their surface heats up – this happens quickly on hot days. On the other hand, in colder weather, their performance drops compared to monocrystalline cells.
When it comes to performance under cloudy conditions or during the days when clouds come and go, you may need to carry a power bank with you rather than relying solely on this solar charger. The current drops pretty fast when shaded and takes couple minutes to restart once again. This means it may not provide enough power to charge your phone on cloudy days.
The manufacturer thought of the practical use for adventurers by designing the product with the protective and light transmitting EFTE coating – therefore, it doesn’t affect the efficiency of solar cells. The coating feels to the touch pretty much the same as a material of your backpack, yet it is scratch proof and has somewhat self-cleaning properties. Additional advantage is water resistance.
Sunslice Fusion Flex 12 is a practical and durable solution for spontaneous, short trips when you don’t know where and through which terrain your steps will lead you. On a sunny day, all you have to care about is your experience, meanwhile, this solar charger will be there to give you a bit of extra power to use your devices when they are running low of battery.

Best for Price: Hiluckey 25,000 mAh Outdoor Portable Solar Power Bank
The Hiluckey 25,000 mAh had the best performance in the solar power bank category. If you’re looking for a solar power bank, look no further than this one.
It features 4 small solar panels that deliver in total 4.8W under direct sun. That’s the most wattage output you can get out of a solar power bank at this moment. While the solar panels on the BigBlue perform four to five times better than the Hiluckey, the PowerPort doesn’t have its own power storage. When there is no sun, there is no power flowing, so an additional external battery is needed to keep devices charged up when the sun is not around.
The Hiluckey Outdoor Power Bank on the other hand, has a built-in battery pack with a capacity of 25,000 mAh which can store enough energy to charge an iPhone 7 about three times and has two USB ports to charge your friend’s smartphone in the same time.
The built-in battery can be recharged by sunlight, but also by wall outlet. It comes with a built-in flashlight and four LEDs that indicate battery life. The casing is shock-proof, dust-proof and water resistant. Great for outdoors
The only drawback of this solar power bank is the charging speed from the small solar panels. In full sun, the Hiluckey built-in battery could reach just 15 percent battery after three hours. However, the charging speed from the built-in battery to our iPhone 7 was very similar to the BigBlue.
We recommend to always charge the power bank by wall outlet before heading outdoors. This way you’ll have enough power to recharge your devices several times, regardless of weather or time of the day. The solar panels on the Hiluckey are not designed as the primary source of charging, but they are a very good alternative to add extra power to the power bank anytime you’re under the sun.
What we like:
- Great value for the price
- High-capacity 25,000 mAh battery
- Overcharge protection
- Two USB ports
- High quality material
- Very compacted when folded
- 12-month warranty

Most common uses of solar chargers
In the hectic world of today most of us cannot imagine our lives without gadgets. And the more advanced they get, the more power-hungry they become. That’s when a portable solar charger comes handy. Think of it like having your personal power supply, anywhere you go.
Complete freedom from power outlets!
Solar chargers are lightweight, foldable and easy to carry around. All you have to do is position the solar charger under the sun and it will immediately start recharging your devices. You can even strap it on your backpack and power up on the go. This way you can enjoy your daily activities without rushing to look for a power outlet somewhere inside.
Considering the fact that solar powered phone chargers are now so much more affordable and efficient, they can be a life-saver in many situations.
Solar energy brings light to our unsustainable developing world and by going solar, be it portable or not, is a great way to join the climate change battle by reducing your carbon footprint.
Important solar charger considerations
The most important features you should look for when choosing a portable solar charger are:
#1 Charge Interruption Recovery
Chances are you won’t be able to use your portable solar charger in full sun all the time. Especially if you live in a place like the United Kingdom. Areas with shade or clouds will affect the performance of your solar phone charger to a certain extent. We measured the output power of each model in full sun, and then in fairly cloudy conditions for one hour each in order to see which solar charger recovers the fastest and gets back on track after being shaded.
The best performing models in this category were the chargers with the most wattage power like the BigBlue. The Neckteck 21W scored the lowest in this test because of the small wattage power.
Larger solar chargers have more solar cells exposed to the sun simultaneously and this makes it easier to recover to maximum output after an interruption.
#2 Charging Speed
Most of the time, portable solar chargers are being used to charge devices such as smartphones, tablets, camera batteries, etc. when source of electricity is not available. This is the reason why we decided to test the charging speed of our solar chargers with an iPhone 7 and see how much it can charge from zero of full in direct sun.
To our surprise we found that the charging speed performance of our models was very different. This significant variability is clearly because of the wattage output power, but also due to type and quality of solar cells.
The winner in this category, the Goal Zero Nomad 20, outperformed the competition with an impressive charging speed.
Our advice: If you are looking for the fastest charging speed, choose a solar charger with at least 15 watts. While smaller panels are more lightweight, the charging speed of a 5W solar charger for example, is around three to four times slower than a 15 watts charger.
#3 Weight and Portability
The ideal portable solar charger would be light, small and easy to carry around. The most lightweight model in our competition is the Hiluckey 25,000 mAh Outdoor Portable Solar Power Bank, weighing just 11.8 oz. This is the only model to get a 10 out of 10 in this category.
However, keep in mind that small wattage chargers are less powerful, so if weight is not extremely important to you, we highly recommend choosing a charger with a higher wattage than the Hiluckey model.
#4 Durability
Since they are used mainly outdoors, solar chargers are constantly exposed to the elements, so durability is a very important factor. All the models we tested had more or less the same quality of material and stitching and all panels were weatherproof.
Solar technology is advancing very fast and companies have already integrated the most advanced features found in residential solar systems into portable solar panels as well.
Watts, Amps, and Milliamp Hours (mAhs)
These are the three most common terms and features that are worth considering when when looking to buy a solar powered phone charger.
mAh – Milliamp hours is the easiest way to measure the strength or capacity of a power bank. This term is not used for the panels themselves, but just for batteries. The higher the mAh, the more power it can store and therefore the longer the power bank will last.
Amps – Amps on a solar charger will determine how fast the electric current flows in order to charge up your devices. The current drawn is different from device to device but in the case of portable solar chargers, you’ll get between one and three amps. The solar chargers we picked in our review test feature the highest amp power available on the market right now.
Watts – Watts are a measure of how much energy is being released to charge your devices. It’s the result of multiplying voltage by amps and they are the most frequently mentioned unit of power. Since USB ports operate at approximately 5 volts, a single 2 amp USB charger port (for comparison: a laptop usually has 1.5 amps in a single USB port) for example, would have a wattage rating of 10W (5 x 2) and therefore would require a 10W panel to charge at 2 amps. But in reality, a 10W solar charger won’t produce exactly 2 amps USB charge because of imperfect weather conditions (Cloud cover) and type of solar cells.
Types of portable solar panels
Solar chargers can either feature monocrystalline, polycrystalline or the super lightweight CIGS panels.
Monocrystalline PanelsMonocrystalline technology is the one that started the photovoltaic revolution and it’s still the most efficient even today when it comes to converting solar energy into electricity. As the name suggests, monocrystalline panels are made from a single crystal of pure silicon. They have an efficiency rating of up to 22 percent and can be easily recognized by their black uniform cells.
Polycrystalline PanelsUnlike monocrystalline panels, the polycrystalline modules are made up of multiple crystals but still deliver a great efficiency of up to 17 percent. Polycrystalline panels have a blue color and they usually cost less than monocrystalline panels.CIGS PanelsCIGS panels consist of Copper, Indium, Gallium, and Selenide solar cells. They are very different than mono- and polycrystalline panels. These panels are the most flexible and lightweight, but also the less efficient out of the three types in converting sunlight into usable power. It’s a good option for backpackers or trekkers who want to travel ultra-light. These are not as durable as the monocrystalline modules but they still do a pretty good job in case of emergency.
Do you need an external battery, or is a solar charger sufficient?
Portable solar chargers can recharge your devices – but only in direct sun. If you want to recharge your smartphone during night time, or on a rainy day, the solar panels will not be of any help.
On the other hand, a battery pack like the Anker PowerCore Elite 20,000 mAh, can store energy and provide continuous and steady power to recharge the same devices you would charge with solar chargers.
Thanks to modern technology battery packs nowadays are very light and can be recharged by solar panels or wall outlet and they can store a lot of energy, enough to recharge a smartphone up to seven times in one go.
Since battery packs can be charged from solar panels as well, adding one to your solar kit means you can have power for your electronic devices available at any time – even when the sun is not there.
How to get the most from your solar charger
Simplicity makes solar power truly remarkable. The only care and maintenance most solar chargers require is making sure they’re clean and dust free. A moist cloth should get the job done most of the time.
To get the highest charging efficiency, it’s important to position your solar panels correctly. A good rule of thumb is that the angle, relative to flat ground, must be approximately the same as your latitude, with a few small adjustments according to the seasons (shallower in the summer and steeper in the winter time).

The Best Solar Phone Chargers
Unlike most portable chargers, solar phone chargers use the power of the sun to top off their built-in battery so that you can charge your phone without the use of an AC outlet. As such, they are a handy option for those who enjoy spending time outdoors and away from a reliable source of electricity.
Buying Guide for Solar Phone Chargers
Why buy a solar phone charger?
- Battery: Most solar phone chargers sport a built-in battery so you can charge your phone even after the sun goes down. If you’re going on a multi-day outing, invest in a product with a large battery capacity that can be charged via AC power before you leave. Compare the battery capacity of your phone (measured in mAh) to that of your solar phone charger in order to estimate how many charges you will get out of a full battery.
- Weight: If you’re buying a solar phone charger to take on long back-country hikes or similarly rugged activities, the product’s weight should be a primary consideration. While multi-panel designs and a high-capacity internal battery may be convenient, these features are sure to add extra bulk and weight. Every extra pound you carry feels that much heavier after a 15-mile hike, so opting for a lighter unit might make sense.
- Durability: Most solar phone chargers are designed for rugged applications. However, not every model is able to withstand the elements. Make sure the solar phone charger you choose is water-resistant, dustproof, and able to survive a tumble or two.
What extra features should you look for in a solar phone charger?
Some solar phone chargers come with handy features that are hard to pass up. For instance, a built-in LED light with an emergency strobe function can be incredibly helpful in an emergency situation. Also, be sure to check out how many devices a solar phone charger can charge at one time, especially if you tend to travel with several devices. Finally, take note of the charger’s battery indicator since an intuitive display will help prevent confusion and give you peace of mind that your device is functioning correctly.
