Four is Better than One

If you’re using a lot of electronics out on the trail and looking for a powerful battery pack that can be quickly r echarged on-the-go via solar energy, you’ll be hard-pressed to find a better offering than the ADDTOP Solar Charger. Unlike many other similar models with one solar panel, this one has four of them. And s ince the unit has an increased number of panels, it absorbs 4x more energy when unfolded.

The solar power of this charger makes 5 Watts and the input current is 1 A. With that, the conversion rate via solar charging reaches as much as 88%. On average, it takes somewhere from 30 to 40 hours to recharge it completely from empty (or 6-8 hours via a 5V/2A adapter). The solar charging speed will be largely affected by the weather and the environment. Since the intensity of sunlight changes at all times, the charging power won’t always reach the maximum value. Theoretically, the most optimal solar charging time is considered to be between 11:00 am and 4:00 pm.

Once fully charged, you can fold all the panels, making the whole thing as small as iPhone X. The unit is rugged enough to use it out in the elements since it has a sturdy polyester canvas that makes it waterproof, shockproof, and dustproof. As a nice touch, it’s made with a flashlight that offers three modes. Normal, SOS, and Strobe.

Luckily, the ADDTOP Solar Charger has a 25000mAh capacity and can charge iPhone 6 around 10 times, Samsung S6 over 7 times, and iPad Air about 3 times. To our surprise, it charges the gadgets for more than 30% in about 20 minutes.

The only thing you should note is that this power bank can charge 5V devices with a USB port (smartphones, iPods, cameras, etc.) but it can’t power up a laptop. Even so, it’s still a very solid power bank with two outputs, high speed, and an emergency flashlight that includes SOS and Strobe modes. Perfect for use in the wild.

All that being said, you should keep in mind that the transformation efficiency of this unit is relatively low, so we wouldn’t recommend you to rely on a solar panel as the main charging source. You’d better charge this battery pack in advance via the mains and then just replenish the power via sunlight.

All in all, the Riapow solar panel has the power and durability you may need for every situation. The soft yet rugged design makes this on-the-go charger practical and aesthetic.

For Serious Adventures

If you’re an avid traveler who often goes on long hikes and needs to carry a couple of different devices, you should definitely take a closer look at the Nekteck 21W Portable charger. It’s a revolutionary solar panel that boasts a very lightweight construction and, accordingly, is much more portable than most other ones with similar specs. The unit weighs just 18 oz and makes 6.3x 11.1x 1.06 inches when folded which allows you to easily fit it into your backpack without adding heft to it. At the same time, despite being that compact and small, it is able to keep two different gadgets at the top battery level.

best, solar, chargers, addtop, charger

Yet, you should bear in mind that because the Nekteck solar charger does not have a built-in battery, it won’t store power for a long time. That’s why you should not leave it in the shadow if you do not want it to lose charge. However, if you wish to store some power bulk, it is a wise idea to invest in a good backup battery (power bank) that can be charged during the day and then transfer the power to your phones at night.

Fast Charging

As mentioned before, this solar panel is equipped with two USB ports and can charge two phones simultaneously. However, the best part is that each port receives the right information about your devices, and smartly distributes the optimal charging current for each connected gadget.

What Is a Solar Charger?

If you often go hiking or traveling, you definitely need a back-up source of energy to power up your electronics since it’s not always possible to get access to the mains when in the wild. That’s where a portable solar charger comes in handy. A solar charger has one or multiple solar panels combined in a single device that can accumulate solar power and transfer it to gadgets that need to be recharged. Some solar chargers can even power up laptops along with mobile phones, players, or tablets.

Lots of solar battery packs are flexible and can be folded to a very compact size, being no larger than a smartphone case. Usually, they are water-resistant, dustproof, shockproof, and drop resistant to endure harsh weather conditions and bumps. So, you can safely clip them on your backpack and head for new adventures that life throws at you.

T o make your choice less tricky, we have rounded up the best solar chargers that are available for sale. In case you want to save your strongest impressions while traveling, we also offer you to check our selection of the best action cameras.

What Features to Compare

Functionality

The main features of any solar powered charger are, probably, its operation mode and available functions. Before making a choice of a charging gadget, you should take into account some important criteria that will help you choose a particular model satisfying your needs and compatible with your mobile devices. Individual chargers may be incompatible with certain models of smartphones or tablets. Other devices might be incapable of charging laptops or might have only USB or micro-USB ports. You should study the input and output ports every gadget has. A charger can be powered directly from solar panels or via a built-in rechargeable battery which can be charged from the mains or solar panels in its turn. The peak power determines how fast your devices will be recharged, whereas the transformation efficiency defines which share of solar energy is converted into the electricity. The more efficient the charger is, the better and faster it will make the batteries of other devices full.

Design

Design is another important criterion affecting the choice of a solar powered charger. The exterior is sometimes the priority for some users. You always look at the appearance first and only after that start assessing specifications and functions. If a device looks good and features versatile functions at the same time, you may buy it without hesitation. Some chargers have several solar panels assembled into a single foldable construction. If it is sufficiently compact when folded, you should pay particular attention to this device. You can’t carry a large solar panel when you go hiking, for example. But, if you select a foldable one, you will be able to store it in a of a backpack and take it out and unfold whenever you want.

Accessories

An independent power source will always be useful for a hike or travel. However, it might be not that convenient to stop, unfold the solar panels, and wait for the charger’s power bank or a device to get full. That is why producers provide their chargers with such accessories as carabiners, clamps, and so on to attach panels to backpacks, tents, trees or other surfaces. The charging will take place while you are walking, riding or doing anything else you want. The manual with detailed instructions will inform you about all the features of your gadget and the best way to use it. Extra connection cables included in the package will save your money and time.

Buyers’ Guide

Charging Capacity

The primary feature you need to check is the charging capacity. Should you have several devices that you know will need to be charged, you need to consider this feature of the solar power bank first and foremost.

Charging capacity is usually measured in mAh (milliamp Hour) which is the number of milliamperes a battery can provide per hour. Obviously, the bigger the mAh, the more charging capacity. For instance, if the battery has a mAh specification of 25,000mAh, it can provide 25,000 milliamperes for an hour.

Most solar power banks come with a rating of 20,000 and upwards of 30,000 mAh. Estimating how much mAh you are likely to need could make a big difference in how much you need to pay too.

In order to best use the charging capacity of your solar power bank you should consider prioritizing your devices. Try to think about which device you are more likely to use in the near future. Your smartphone, the tablet, the ebook reader?

Each device will have a different sized battery; the battery for a tablet is likely to be bigger than that of a smartphone. If you can estimate the required mAh of your solar power bank you can narrow down your choices.

The number of ports the solar power bank has will also impact on the charging capacity. Ideally, you will want to charge multiple devices at once which will provide a significant drain on the battery. However, some solar power banks can hold their charge for a number of weeks yet may only be relied upon for a few charges at a time.

To reach that charging capacity you may have to rely on the weather, specifically whether the sun comes out beyond the clouds. There are some solar power banks that only take a matter of hours to fully charge.

However, others may take multiple days to charge from sunlight alone. That is largely why a lot of manufacturers suggest ensuring that your solar power bank is fully charged from a wall socket before you set off.

Several manufacturers do design their solar power banks specifically for emergency purposes. This is so the solar charging is classed as a secondary feature with the main intention that the charge is held in case you need it.

Being able to charge your devices while you are out exploring is an ideal way of ensuring you can still use your devices when you need them. If you can rely on exposure to sunlight then you can be assured that your cellphone will be charged, as well as your tablet or ebook reader if you need it. That means you can simply concentrate on your off the grid experience.

Ideally, you should only need a solar power bank when you truly require it, though it does act as a great accessory to take with you. If you know you are going to take a long trip or need an alternative energy source for a new life off the grid, a solar power bank is a super option.

However, to fully make use of it you may need to find one with the most solar charging capacity. This is how much the solar power bank will be charged from direct sunlight. You may also need to make sure your solar power bank can withstand the elements if you want to use it as you want it.

For that you should check the IP rating (more information is included on that below). Those solar power banks with several solar panels attached are usually a bit more fragile so should be considered primarily for use in summer.

Weather Resistance/Durability

A lot depends on the weather, especially for your solar power bank. Having said that, most solar power banks can take a bit of rain. While most will not be completely waterproof, they can typically handle a few spills. They are designed to be exposed to the elements after all.

If you do need to compare how waterproof a solar power bank is then you need to check the IP rating. This will also indicate how dustproof it is too.

An IP rating consists of two numbers. The first number indicates how dustproof the solar power bank is with six being the highest value available. The second number refers to how waterproof it is and a 7 would mean that the solar power bank can be submerged in three feet of water for up to half an hour.

An X for either value would mean that the solar power bank has not been tested for that resistance. For instance, an IPX5 rating would mean that the solar power bank has not been tested for dustproofing but the five means it should comfortably resist a sustained water jet spray at low pressure.

Maximum Output/Time To Charge

While the charging capacity should take precedence in your decision-making, how long the solar power bank takes to charge a device is also important. For that feature, you will need to check the maximum output rating.

Just like the charging capacity, the bigger the value the better. The maximum output will typically be measured in watts and an 18-watt solar power bank will provide much faster-charging speeds than one with ten watts.

Size

A solar power bank that is worth the investment will likely come with large solar panels. The bigger the coverage, the higher the charging capacity, and the maximum output.

This is really important for backpackers as some solar power banks can be foldable. You can even attach them to your back and charge them up as you hike.

For Travelers On Short Trips

If you are embarking on a short trip, you may need to ask yourself how many charges you need. For a daytrip you may only need to make sure that you use your cellphone all day and still have some charge just in case.

A few extra photos perhaps, maybe listen to a podcast or record a video to capture that special moment. If you do just need a boost of juice then simply make sure that the solar power bank is fully charged after each trip.

That will likely mean you do not need to consider the solar charging capability, especially if you cannot rely on sunshine.

Should you be going on a multi-day trip to somewhere remote you can rely on a solar power bank for a few charges. This should cover your devices for a few days and it will likely prove more reliable than a regular power bank as you have extra functionality.

You should not even worry about staying out for a couple more days. As long as there is some sunlight for a few hours, that should be enough for a full charge to cover your devices.

For The Forgettable

There is always someone in a traveling party that completely forgets to charge their devices. For most, the prospect of setting off without a fully charged device is enough for a panic attack before the day has truly begun.

Should you be the one liable to forget to charge your devices then having a fully charged solar power bank is a superb idea. Maybe keep one in your vehicle or your luggage so you know that if you do forget, there is still another power source ready to go when you need it.

This is especially important if you are going on a trip and want to remain contactable for family and friends. You may also need to be contactable for work, in which case having a solar power bank in your vehicle or office desk is a really Smart thing to do.

It would be far easier to carry a solar power bank than take your charger and wonder where to find a power outlet.

For Life Off The Grid

Living off the grid should mean relying on nature. That can mean filtering your own water, hunting your own dinner and having a stocked up cellar. A solar power bank should be a crucial part of your emergency kit.

Especially as it can hold charge which could be crucial in a disaster. Being able to charge your devices without relying on the infrastructure is also incredibly liberating.

While life off the grid should be emancipating you should still be able to rely on some modern technology. That includes your solar power bank so try to find one that can hold its charge well. Having an alternative power source that you know is readily available is a welcome comfort.

For The Environmentally Conscious

Those who want to make a difference on their energy consumption may want to consider a solar power bank. Solar panels are already well known as a great energy source and solar is certainly considered to be the energy of the future. Maybe even right now.

Solar power is accessible and it only requires a small investment to have your own convenient energy source with a solar power bank. Even a small solar power bank can make a huge difference if you can attach it to your bag every day.

Weight

The weight of your solar power bank is really important to consider. An experienced backpacker will know that every ounce counts. While you will have your essentials packed there are other items which are ‘nice to haves’. An extra t-shirt or a different hat. Your solar power bank should be an essential item to take with you but the weight all adds up.

There is a bit of weighing up to do with a solar power bank. The bigger and heavier ones will typically provide more battery charging capacity as the solar panels, and the battery itself, will be bigger and bulkier.

However, you will have to carry it. If you are an experienced backpacker who can spend a few days out on a hike you likely want a bit more charging capacity. Especially if the weather may not bring so much direct sunlight. However, if you are only going for a day hike you may be able to get away with a smaller, light solar power bank.

If you only have a large solar power bank that is ideal for longer hikes, then it may be more convenient not to take it. The likelihood is if you use your devices wisely you probably will not need to charge them. But if you have a smaller solar power bank that you can top up during the day then that may suit the job. Just don’t forget to charge it before you begin your hike.

Output Ports

Being able to charge all your devices at once is a massive boon to have which comes with a lot of solar power banks. Yet that also takes into account the number of devices you will be carrying. If you only need to pack your smartphone and a tablet then you only need two ports.

However, should you go on a longer trip and want to take an ebook reader perhaps you will want three ports. Almost all solar power banks will use full-size USB Type-A ports for output which means they will be compatible with a cable of your choice. However, for input they will either use micro-USB or USB Type C so take that into consideration.

As a general rule, look out for solar power banks that have two output ports and two input ports as these provide great versatility.

Extras

For solar power banks that can offer a higher solar charging current, you are likely looking at multiple, folding solar panels. These tend to come with a clickable action so that they can be unfolded easily then clipped to the back of your backpack.

Charging on the move is a great option to have to keep the power bank ticking over. You can also expect a set of three or even four solar panels on offer. The more solar panels, the higher the coverage and the higher the solar charging current.

A handy feature to look out for is an LCD display. These will give you a real-time countdown of how much charge you have left. Some even tell you how much of that charge is available from current exposure to sunlight.

FAQs

Can solar power banks be charged without exposure to sunlight?

Yes, they can be charged without direct exposure to sunlight. A lot of solar power banks will have battery banks, these work without being solar charged. You can plug them into another power source, or simply use a traditional wall outlet depending on the accessories and cables you have. If the solar power bank does not have one of these battery banks it will require exposure to sunlight and a direct connection to the solar power bank to charge.

What’s the difference between a solar power bank and a solar charger?

There is one subtle and telling difference between a solar power bank and a solar charger. A solar power bank has a battery, a solar charger does not. That one detail can determine which device you go for. If you know you will be going on a long trip and the weather may be temperamental, opt for a solar power bank. That way you can fully charge your device and even if the sun goes behind the clouds, you still have some charge reserved in the battery. That ‘just in case’ aspect can make a crucial difference so you are not depending on the weather and sunlight exposure. Having power stored away is a comforting notion and saves you the worry of checking the weather. However, a solar charger is ideal for long backpacking trips when you know you will be out in the sun for hours. They are also comparably lighter and if you can rely on the sun they are more efficient and will provide a faster charge.

Why You Should Invest In A Solar Power Bank?

Simply having a solar power bank is a great item to take on your next trip. Being less dependent on the grid is a wonderful freedom to have. The freedom to know you can charge your devices in the sunshine even though you may be spending a few days in a rainforest. Or the desert, or at sea.

If you only have a solar charger there is not so much a dependency on the grid but the sun. With a solar power bank you can reserve the charge for when you need it the most.

Knowing that you can still charge your cellphone when the sun goes down is a comforting thought when you are so far away from a power outlet. Convenient and environmentally-friendly, a solar power bank could also be the most important thing you pack should an emergency arise.

Reasons your solar power bank is not charging

There are many reasons why your solar power bank might not be charging. Here are the five most common ones:

The battery has reached the end of its life

Unfortunately, no battery lasts forever. It’s inevitable that it’ll reach the end of its lifespan after performing a certain number of cycles. If you’ve had your solar power bank for some time, your battery might have lost its ability to hold a charge.

You’re not using it properly

Although technically, you use your solar power bank while it’s charging (in an emergency, for instance), this practice isn’t recommended. Doing so frequently may result in your solar power bank not charging or charging erratically. When you do this, the power banks’ battery is in line (or in series) with the gadget. The result is a higher power draw which leads to excessive heating that can damage your battery.

Your solar panel isn’t getting enough sunlight

A common misconception is that the solar panel in your solar power bank can generate electricity on a hot day, even when placed in the shade. That is not true — solar panels require direct sunlight to work effectively. Additionally, solar power banks require a minimum amount of luminous flux per area unit (also called lux). If they don’t receive the minimum amount of lux, they won’t start charging via solar. The following image showing the charging instructions of a standard solar power bank serves as an example. Notice that it requires a minimum of 25,000 LUX sunlight to charge via solar.

Wrong or broken charger/power cable

If you’re trying to charge your solar power bank using a USB charger and it isn’t charging, the issue might not be your power bank. It could instead be the charger or the cable. Make sure you’re using the correct charger, one that delivers the proper voltage and current (as required by your solar power bank). If it still doesn’t work, the charger (or just its power cable) could be broken.

Excessive battery drainage

We recommend that you recharge your solar power bank before you drain it completely. If you drain your power bank completely, it’ll require more energy to get going again instead of charging it from a 50% state of charge. As a result, if you deplete your solar power bank entirely, it might take even longer to charge with solar, or in a worst-case scenario, it might not charge at all. Related reading: How To Use A Solar Power Bank – A Helpful Guide

How do I know if my solar power bank is charging?

Charge your power bank properly. Doing this ensures that it provides you with power when you need it.

Led indicators

Most Solar Power Banks on the market have four tiny LED indicators that flash progressively when charging. Although they may vary in size and color, you can quickly identify them on your Solar Power Bank. Advanced models display different LED colors to indicate the charging source. After reading the User Manual from a few different Solar Power Bank models, we’ve noticed that for most models:

  • Blue LED: Indicates USB port charging
  • Green LED: Indicates solar charging

Furthermore, the LEDs indicate the state of charge when the solar power bank isn’t charging (and the LEDs aren’t flashing). In this case, the lights represent:

  • 1 LED on = 25% state of charge
  • 2 LEDs on = 50% state of charge
  • 3 LEDs on = 75% state of charge
  • 4 LEDs on = 95%-100% state of charge

Logically, when fully charged, your solar power bank should have its 4 LED Indicators active. As it discharges, the indicators gradually turn off.

Because of the variety of models, you might find yourself with a device that indicates charging differently than the way we described.

For this reason, we strongly advise that you read your device’s user manual. There, you’ll find all the information you need, specific to your solar power bank model.

Ways to fix a solar power bank that won’t charge

If your solar power bank isn’t charging, don’t panic! Here are a few things you can try to get it up and running again:

Add extra solar panels

If you’re trying to charge your power bank with solar energy after draining it completely, it may not charge at all.

Why? The surface area of your power bank’s solar panel might be too small to generate enough electricity to get the redox reactions in the battery going.

In this case, adding extra solar panels might fix the problem. You can attach/connect small solar panels to your solar power bank (if it supports this addition) – you can easily find them online.

This will increase the solar input of your power bank until it recharges to at least 50%. After this point, the electricity generated by your main solar panel (without the extra ones) will probably be enough to continue charging your power bank.

Try charging it with electricity from a wall outlet

As mentioned above, your power bank might be too drained to start recharging only with the small energy input the solar panel provides. If this happens, don’t give up on your solar power bank just yet. Pumping up some juice from a wall outlet might bring it back to life.

Place it in direct sunlight for an extended period

Solar Power Banks can take over 50 hours to recharge using solar energy. Considering how many hours of sunlight are in a day, it could take an entire week to recharge your solar power bank.

For this reason, it may seem like it isn’t charging, when in reality, it’s just taking a long time.

To maximize sunlight absorption and overall efficiency, one way of speeding up this process is to place your solar power bank in direct sunlight for an extended period.

Check for any loose connections

For instance, your solar power bank might not be charging because the wire that connects the solar panel to the circuit board is loose.

In this case, using a soldering iron to solder the loose wire will fix the broken.

Check if the battery is dead

This one also requires exposing the inner pieces of your solar power bank.

Depending on the battery’s chemistry (and its nominal voltage), you can tell if it’s dead by using a voltmeter to check its voltage.

If you conclude that it’s dead, the only way to fix your solar power bank would be to replace the battery. This procedure might not be cost-effective, so do your research before buying a replacement battery.

Here’s a little tip: You can also use the voltmeter to measure the output voltage of the solar panel. Maybe the battery is fine, but the solar panel isn’t generating any electricity.

If you’ve exhausted all your options, and cannot find a way to fix your solar power bank, it’s time to invest in a new one.

The Best Solar Power Banks of 2023

Smartphones and other devices let us stay connected wherever life’s adventures take us… until the battery runs out. Solar power banks promise to end the hunt for power outlets, letting you harness the power of the sun to charge your devices even in remote areas.

How Does a Solar Power Bank Work?

The market for portable batteries is very crowded. Most charge only from a wall or USB socket, but some also have the option of charging from solar panels. Sometimes the panels are completely separate, but most smaller solar power banks use panels that are either built in or can be attached to the battery for portability.

Larger solar power banks may offer a choice of plug-in bi-fold or tri-fold solar panels, while smaller units typically use a fanfold design for the panels. All let you charge from a USB-A and/or USB C socket, while others add extras like Qi wireless charging and (on larger models) AC and DC power as well.

While versatile, you’ll still find a particular solar power bank is best suited to certain kinds of use. A power bank designed for smartphones, for instance, isn’t likely to charge your laptop efficiently (or at all). Larger units can handle bigger charging jobs, but at the expense of easy portability.

Carefully consider how you’ll use your solar power bank before clicking the buy button.

Single-Panel vs. Multi-Panel Solar Power Banks

Keeping the weight down is always important when you’re carrying all your gear, which can make single-panel power banks appeal for things like hiking and bike camping. However, you’ll be a happier camper (pun intended) if you invest in a model that uses multiple panels.

Single-panel units often take an extremely long time to recharge the power bank, with many models never reaching a useable charge level even after a full day in the sun. Multiple panels let the power bank recharge significantly faster, making them a must-have feature as far as we’re concerned.

Fortunately there are many compact power banks out there with a foldable multi-panel design. While they’re a little larger and heavier than their single-panel siblings, there’s often not a big difference — and if you’re buying a solar charger, don’t you want one that actually charges in the sun?

️ If you already have a power bank and are just looking to charge it using the sun, we’ve got a range of recommendations for the best solar chargers as well!

Best General-Purpose Solar Power Bank: BLAVOR W12Pro

There’s a lot to like about many of BLAVOR’s products, but our favorite is the well-rounded W12Pro. Overall, it’s our top general-purpose solar power bank pick for most people.

The 20,000mAh capacity is a useful size for a portable solar power bank like this, with enough juice to recharge a tablet once or twice, or most smartphones multiple times, while not being excessively heavy. Robust and reliable, the W12Pro can take a fair amount of abuse, although it’s not fully waterproof.

A foldable four-panel design helps the W12Pro recharge faster, while still remaining reasonably compact and easy to stow in your bag. The W12Pro’s solar charging panels, rated at up to 300 MA per panel (1.2 amp total) are enough to top off the power bank between uses on sunny days.

The W12Pro supports both Power Delivery (PD) and QC 3.0, allowing charging of supported devices (including some smaller laptops) at up to an impressive 18W. As well as a microUSB input, there are two USB-A outputs and a single USB C port.

The USB C port is for charging either your device or the W12Pro itself, so you can use it to quickly recharge the power bank from a wall outlet before you hit the road. As with most solar power banks, we’d recommend doing this: while the charging rate from the four panels is much better than single-panel designs, you’re still looking at a couple of days of sunshine or more for a full charge.

Extra goodies include two lights (one focused, one covering a wider area) that can be adjusted through three brightness levels. There’s also an inbuilt compass, but no Qi wireless charging, so you’ll need to look elsewhere if that’s a requirement.

  • 18W PD and QC 3.0 fast charging
  • USB C and 2x USB A ports
  • Foldable 4-panel design
  • Built-in camping lights
  • Water-resistant, shockproof design
  • No Qi wireless charging
  • Takes 2-3 days to fully charge from sunlight
  • Bulkier than some other options

Best Solar Power Bank for Camping: Jackery Solar Generator 500

If your camping needs include a bunch of electronics, a small solar power bank isn’t going to cut it. You’ll need something much more powerful to charge your devices or power small appliances while you’re relaxing in your camp chair.

Our top pick for drive-in camping is the Jackery Solar Generator 500. The 500 in the name speaks to the power bank’s whopping 500-watt output, which is enough to charge laptops, run camping coolers, or even power a portable TV if you just can’t miss your favorite show.

If you need more power (and have a bigger budget), you can also consider Jackery’s 1000-watt solar power bank that impressed us during our review. Budget shoppers can also look at Jackery’s 300-watt model that’s cheaper and lighter, but has less power and capacity.

Larger models like these use a modular design with a heavy-duty power bank paired with your choice of solar panels to charge it with. You’ll trade some portability for versatility here: these units are comparatively big and bulky, but are also up to the task of much bigger jobs.

The Jackery Solar Generator 500 offers several attractive features, including pass-through charging that lets you power devices while the generator recharges from solar, vehicle, or mains power.

The unit has a 110-volt AC outlet so you can plug in gadgets just like you were at home, plus three USB sockets and three DC ports, including an auto-type adapter.

Jackery’s 500-watt solar power bank can’t run high-power devices like hair dryers or microwaves, just in case you were planning on taking those along on your next camping trip, but it’s ideal for powering a wide range of other devices.

  • 500-watt continuous output (1000-watt peak)
  • Multiple charging methods: AC, DC, solar
  • Can charge to 80% via solar in 7.5 hours (with 100-watt panel)
  • Pass-through charging
  • Multiple charging sockets

Best Solar Power Bank for Backpacking: Sunslice Photon

Weight and bulk are big considerations when backpacking, and that’s as true for power banks as anything else. Enter the Sunslice Photon, advertised as the smallest portable solar charger in the world.

The Sunslice Photon pairs five small solar panels with a 4000mAh power bank that’s enough to top off your phone even if your journey takes you miles from civilization. Sunslice includes a small, clip-on cable that fits all popular smartphones, so there’s no need to pack a separate one.

You’re able to quickly charge the power bank via its USB C port (input-only) before hitting the trail less traveled, and once it’s depleted, you’ll get enough juice back into it to charge most smartphones in about three hours using solar power.

At just 7.8 ounces, the Sunslice Photon packs a lot of punch for such a comparatively small, lightweight package. Folded, the power bank is smaller than most wallets. With all five panels extended, the device can easily attach to a backpack via the inbuilt carabiner without getting in your way.

A flashlight is built in, which is always a useful extra when camping, and the magnetic closure on the power bank helps keep the panels secured when you’re not using them.

While we’d like to see a higher capacity battery in the Photon, it’s still enough to fully charge most smartphones, and an acceptable tradeoff for such a small device. For hiking or backpacking, the high efficiency and lightweight design makes the Photon our top pick in this category.

  • Super lightweight
  • Foldable multi-panel design
  • Compact size
  • Weather-resistant materials

Best Solar Power Bank for Emergencies: ROCKPALS 300W Portable Power Station

For home use or emergencies, the capable 300-watt portable power station from ROCKPALS offers a compelling value. Whether you need to power your laptop in your sun-kissed backyard gazebo or charge multiple phones during a post-storm blackout, this is the device to do it with.

With up to 300 watts of continuous power and a 500-watt peak power rating, the ROCKPALS 300 is ready for most home or emergency uses. A battery capacity of 280wh offers enough power to recharge phones and other small devices several times over.

Paired with fanfold 100-watt panels, the power bank recharges from the sun in about five to seven hours. Other recharging options include AC charging, DC charging from a vehicle, and USB C power delivery (PD) at 30 watts.

You can power a range of devices and gadgets thanks to the wide range of outputs. There’s an AC outlet, three DC sockets (including a cigarette lighter-style 12v port), a USB C PD port, and three USB-A jacks.

The unit supports passthrough charging for the DC and USB ports, meaning you can recharge your devices while the power bank itself is charging. You’ll have to wait a bit before plugging in more demanding devices, though: there’s no passthrough power for the AC outlet.

At under eight pounds, the ROCKPALS 300 offers portable power on demand, making it a solid alternative to generators for home or emergency use. If you’re looking for something more heavy duty, ROCKPALS also makes a 500W/505Wh model, and there’s also the Jackery 1000 mentioned above.

  • Fast solar charging (under seven hours)
  • High power output
  • Multiple charging methods
  • Modular and portable
  • Pricey
  • Not suitable for high-wattage appliances
  • Qi wireless charging not supported

Best Solar Power Bank for Travel: BLAVOR W09

BLAVOR makes its second appearance in this roundup, this time with the best solar power bank for travel. For this category, we looked for a device with a useful battery capacity that could take a beating (within reason) while bumping around in a suitcase or travel bag.

We also wanted a power bank that offered Qi wireless charging and the ability to charge at least two devices at once, making it appropriate for as many of the devices that people are likely to be traveling with as possible. The BLAVOR W09 delivers on all those requirements and more.

Like some other solar power banks, the BLAVOR W09 uses a foldable five-panel design that keeps the overall dimensions small. However, we liked that the solar panels could be detached from the power bank, offering a safer way to transport the unit and reducing the risk of damaging the connectors.

This design choice also lets you save space and use the unit as a standard power bank if your travel day won’t require you to charge it via solar power.

The BLAVOR W09 has a pair of USB-A ports, one for slower (5W) charging, the other for higher-speed (12W) charging. Place a phone that supports Qi wireless charging on top, and you can charge three devices at once. At 20,000mAh, there’s enough capacity to charge all your phones once, or one phone several times.

There’s both a microUSB and USB C port for charging the power bank itself (they’re both for input only), and as with the W12Pro above, there’s a compass and inbuilt flashlight as well.

  • Qi wireless charging
  • Charge up to three devices at once
  • Folding, detachable solar panels for travel
  • Flashlight and compass included
  • No fast charging
  • No USB C charging
  • Qi wireless charging is quite slow (5W)
  • Takes 2-3 days to fully recharge from solar
