    Are Portable Solar Chargers Worth It?

  • Harnessing power from the sun is a great way to recharge gadgets or your smartphone for free while you’re out camping, going off-grid, or dealing with an emergency. However, portable solar panels aren’t free and are not always effective. So, are portable solar chargers worth buying?

    A portable solar panel is exactly what it sounds like. You can take a small set of panels anywhere, aim it at the sun, and then use that power to recharge your phone or a portable battery pack.

    USB solar chargers are a great option if you’re taking an extended camping trip or other activities. And while I’d recommend a portable battery first, those will inevitably run out of juice, not to mention can be heavy if you’re going on a hike. Portable power stations are great, too, but they’re even bigger and way too heavy for most adventures. Plus, once you use it enough, it’ll run out of battery.

    That brings us to portable solar panel chargers, which give you free on-demand power anywhere the sun shines. While they certainly have limitations and speed constraints, here’s what you need to know, why I own several, and a few worth buying.

    How Solar Panel Chargers Work

    Before we dive into portable solar panel usage scenarios, charging speeds, and what to buy, we wanted to quickly mention how they work.

    A portable solar panel works essentially the same way as a regular solar panel on a roof. That said, they’re smaller, likely not as efficient, and if the power goes directly into a device, it’ll be somewhat slow.

    When the sun shines on a solar panel, the panel cells absorb energy from the sunlight. That energy quickly creates electric charges that move around the positive and negative electrical fields inside the panel cell, letting the energy flow into a storage device or battery.

    Think of it like magnetic fields, only electric. In a panel, the sun gets absorbed, electric charges move, then flow through the electric field and into your smartphone.

    Can a Portable Solar Panel Charge My Phone?

    The short answer is yes, absolutely. Portable solar panels can easily recharge a smartphone, tablet, or drone, or juice up a portable battery pack for use later. However, there is a slew of different variables you’ll want to consider before buying one.

    For starters, these only work when there’s sunshine, and some areas get a lot more rays than others. So, a portable solar panel won’t be effective if you’re somewhere like Alaska in the winter, which doesn’t see the sun all that much. Locations with more sunshine (and fewer clouds) will benefit the most.

    In my Anker 515 portable solar charger review, I had excellent results charging a Galaxy S21 Ultra and Pixel smartphone in the blistering sunshine here in Las Vegas. However, it’s not powerful enough to recharge a MacBook Pro or larger items. And while brands sell bigger “portable” panels, it’ll depend on your needs.

    Unfortunately, not all panels are worth buying, in my opinion. I own a few Jackery panels, which work great, but smaller panels from unknown brands aren’t worth it. I have a small portable solar charger roughly the size of a smartphone. It’s mostly useless. That’s because it simply doesn’t have enough solar panel material (or real estate) to actually draw enough power from the sun to make it worth the effort.

    Depending on the weather conditions, the Anker 515 can recharge my phone from 0-50% in around 90 minutes or so, which is terrific for going off-grid or in an emergency. One of those tiny phone-sized panels can’t, so keep that in mind.

    Don’t get me wrong. A tiny portable solar panel charger can give you a few percent and enable a text or phone call in an emergency, so they certainly have benefits. It’ll just depend on your wants and the situation.

    Anker’s 24W flexible solar panels can charge three devices at a time at up to 9w per device.

    What features to look for in a solar phone charger

    When you’re shopping for a solar phone charger, there are a few things to keep in mind to make sure you get the right one for your needs, including:

    How Long Does It Take a Solar Charger to Charge a Cell Phone?

    Cell Phones are becoming increasingly essential for daily living.

    In off-grid living, they help in keeping communication with friends, family, colleagues, and the likes.

    For this reason, a solar charger is important to charge a cell phone outdoors.

    Smartphones are very portable, making them easy to use outdoors.

    However, the main problem is their duration of charge with solar chargers.

    A solar charger will charge a typical cell phone in 2.5-3 hours from a 5W solar panel, 1.3-1.6 hours from a 10W panel, 52 minutes to 1.1 hours from a 15W panel, and 39-50 minutes from a 20W panel. These stats are based on a solar charger utilizing 80-100% of its listed power output.

    Both the wattage of your solar charger as well as the battery size of your smartphone come into play when estimating recharging times.

    The average charge times for various popular smartphones can be seen below. BigBlue 28W solar charger (portable solar panel)

    Goal Zero Venture 35 Solar Kit with Nomad 10 (portable solar panel with battery bank)

    Hiluckey Solar Charger (power bank with embedded solar panel)

    • Portable solar panel with USB ports – Plug in your phone directly into the panel
    • Portable solar panel with a battery bank – Either plug your phone directly into the panel or use the battery bank to charge from solar first before using the battery bank to charge your phone
    • Power bank with embedded solar panel – Solar panel is sealed to the battery bank

    Most solar power banks with embedded solar panels have a good size battery but lack solar panel output power.

    The best “solar charger” for recharging your cell phone is a portable solar panel of 10W or more along with a battery bank.

    Using the solar panel to recharge the battery bank will be the best way to recharge your cell phone from solar because solar power is inconsistent due to weather changes.

    This could affect the way the panel charges your phone if you connect them together without the use of a power bank.

    For example, I used my Nomad 10 solar panel to directly charge my iPhone 7 and it worked successfully, however, any Cloud cover would stop the charging and my phone would go back and forth from charging to not charging.

    Charging a power bank would simply allow a faster charging process because it will provide consistent power to recharge your phone – as opposed to your phone constantly going in and out of sleep mode to show it’s charging.

    If you’d like more information on power banks with embedded solar panels, I created a list of the top models and go into more detail on them in my article here: Top 7 Solar Panel Battery Banks – A Battle for Power.

    Top 3 Solar Phone Charger Examples

    The following examples will be portable solar panel models that can be used to charge your phone directly or indirectly via an optional battery bank.

    In several cases, you can buy these in a kit along with a battery bank, like the Goal Zero Venture 35 with Nomad 10 kit (affiliate link).

    BigBlue 28W USB Solar Charger

    The BigBlue 28W USB solar charger is one of the most suitable chargers for cell phones. It possesses four different foldable SunPower solar panels that are very compact.

    Also, it has three 5V/2.4A (max) USB output ports for simultaneous device charging.

    However, the panel is best used with a maximum of two USB ports simultaneously to get the full 5V/2.4A for both ports.

    This means that the USB ports combine for a maximum of 24W of output (5V/4.8A), which is not 28W but is still a relatively high number for a portable solar charger.

    According to reviews, the BigBlue 28W USB solar charger appears to deliver a good output in sunny and, surprisingly, cloudy conditions.

    On the downside, the BigBlue is a long solar panel when unfolded (33 x 11 x 0.2 in). Hence, users need to remain conscious of their size when using it for backpacking needs.

    Nekteck 21W Solar Charger

    The Nekteck 21W solar phone charger has three solar panels and two standard USB-A ports.

    Each port is capable of 5V/2.0A when one port is used, but when using both ports, the maximum amperage is 3.0A (15W max).

    Like the BigBlue, the Nekteck outputs less power than the panel says in its listing. That being said, 15W is enough to power up a smartphone or multiple phones when needed.

    Although it has less power than the BigBlue panel, it’s more compact with an unfolded length of 26.2 inches.

    This may be easier for you to mount onto your backpack or tent as it is about seven inches shorter than the BigBlue.

    Impressively, it is also a lightweight solar charger, weighing only 18 ounces in total.

    Goal Zero Nomad 10 Solar Charger

    The Nomad 10 is an impressive product from Goal Zero.

    It comes with a foldable solar panel, which has a wide surface area.

    It weighs 1.2 pounds, which makes it relatively heavy, but compact.

    The 10W, 6-7V panel comes with a built-in USB-A port, which functions effectively.

    I’ve used this panel to successfully charge my phone directly, but the best option is to use one of Goal Zero’s battery banks for charging up.

    The Flip 12 or Venture 35 are some options that are smaller for portability.

    The two downsides to this panel are its decreased power output compared to the previous two panels as well as its cost.

    The Nomad 10 by itself costs almost double that of the BigBlue or Nekteck panels.

    But its compact size makes it useable for almost any purpose (9.5 x 14.5 x 0.75 inches unfolded).

    You can see how the Nomad 10 worked in my own testing to charge my Sherpa power bank in my video below.

    You can speed up your solar charger by angling it perpendicular to the sun and charging one device at a time. A direct angle to the sun allows the charger to absorb as much sunlight as possible. Charging one device at a time avoids splitting the charger’s output power between multiple devices.

    If the device is placed outside your backpack while moving, please note that it may not charge fast.

    Since you are on the move, there’s a high probability that the panels aren’t always facing the sun resulting in inconsistent charging.

    If you want a faster charge from the solar phone charger, you may also consider using shorter cables.

    Please note that shorter cables don’t necessarily make the solar phone charger work faster. However, it helps in the overall charging speed due to a minimal amount of wasted energy.

    It may also be advisable to purchase a solar charger with a battery to help store power, which allows the user to charge at a time of convenience.

    Do Solar Phone Chargers Really Work?

    Solar phone chargers really work as long as they’re exposed to quality sunlight. It’s essential to pick a solar charger with at least 10 watts of power. A 10W solar charger will recharge a typical cell phone in 1.3-1.6 hours. Any charger less than 10W may output too slow of a charge to your phone.

    Solar phone chargers that are closer to 15 watts or higher can charge a mobile phone along with other devices simultaneously.

    The portability of your solar phone charger matters a lot.

    Hence, it is important to confirm the weight and dimensions (folded and unfolded) of any panel you intend to purchase.

    If your solar phone charger has large folded solar panels, it may be too heavy to carry.

    However, large folded solar panels may have higher efficiencies (charge devices faster) due to a wide surface area.

    For example, my Elecaenta 120W solar panel is massive and weighs almost 12 pounds! But this is clearly too powerful of a panel for simply charging a phone in most scenarios.

    Some solar phone chargers don’t function well compared to others, depending on their output.

    Ensure that you pick a brand of solar charger that works efficiently and that has good and honest reviews.

    If you ever come across issues with your solar charger, I have a guide to troubleshooting your panel to get it working again. I also have some maintenance tips to prevent you from running into any issues while using it off the grid.

    Is There a Difference Between Rechargeable and Solar Batteries?

    There is no difference between rechargeable and solar batteries. Solar batteries are used in storing chemical energy, which gets converted to electrical energy. Solar panels trap energy from the sun, and it gets stored in batteries for later use. Hence, solar batteries are rechargeable batteries.

    In some cases, solar chargers don’t come with rechargeable batteries (or any battery at all), which is usually a challenge.

    A significant example of a product that doesn’t come with a battery is the Nekteck 21W solar charger. Users will need to buy a separate battery pack to make it a power bank as well.

    Rechargeable battery

    Rechargeable batteries are electrical batteries that can be discharged and charged multiple times. However, they are produced in different shapes, sizes, and specifications.

    There are lots of different combinations of electrolytes and electrode materials utilized. Examples are nickel-cadmium (Ni-Cd), lithium-ion (Li-Ion), nickel-metal hydride (Ni-MH), lithium-ion polymer (Li-Ion polymer), and lead-acid.

    Li-ion batteries are very stable batteries with a low self-discharge rate but high energy density and voltage capacity. Besides, they are very durable batteries.

    Li-ion batteries tend to last for eight or more years and have nearly zero memory effect. So, even if the are a little high, it is worth the investment.

    How to Charge SolarCell Remote Neo QLED TV Samsung

    In 2021, Samsung proposed a new type of remote control for some models of its TVs. This remote control is called SolarCell Remote.

    What is the difference between Solar Cell remote and other Samsung Smart Remotes

    The remote control performs the same functions as the previous models but is structurally different. For example, instead of standard replaceable batteries, the remote control has a rechargeable battery. The Solar Cell remote control needs to be charged, for this purpose, the remote control has a USB-C connector. Also, the remote control can be charged automatically from the built-in solar cells.

    How to charge the Samsung Solar Cell Remote explained

    The Samsung Solar Cell Remote can be charged quickly enough. Here are some solutions:

    • Use a standard phone charger, the remote will charge in about 20 minutes.
    • Connect the remote to the USB port on your TV, the remote will charge in about 30-40 minutes.
    • Plug your remote into the USB port on your laptop, and it will be charged in about 20-40 minutes.

    Samsung has considered that charging from a power source is not the best solution, so there are solar cells on the back of the remote control. All you have to do is lay the remote with the buttons down so that the solar panel generates an electric current. It takes quite a while to charge from the solar panel, but it all depends on the intensity of the outside light.

    How much time do you need to charge the Samsung Solar Cell remote control with solar elements

    As I said before, it takes no more than one hour to charge the remote control from an external power source. If you charge longer than that, it will not cause any noticeable damage to the remote control, but it is not reasonable. At the same time, you can charge from solar cells for an unlimited time.

    How to check the battery level of the Samsung Solar Cell remote control

    The Smart remote control is quite an advanced device, the status information of the remote control is displayed on the TV. You can find out the battery level by looking at the remote control information on the TV. To do this, open the TV menu and find information about the remote control. Here’s what you need to do:

    Samsung Solar Cell lifespan explained

    The remote control is a small device, so it can be accidentally damaged. However, the lifespan of the remote control, if you use it under normal conditions, is equal to the lifespan of the TV. That’s about 7-10 years.

    Samsung solar remote not charging

    If the solar remote control cannot be charged, proceed as follows Try to charge the remote control via the charging port. You can use any USB and USB-C cable for this. Modern phones use a cable that can be disconnected from the charger. Any USB port, such as the one on your TV, can be used for charging. The USB supply voltage is 5 volts. If the remote control cannot be charged via the USB port, it is probably defective and needs to be replaced.

    Can I use the charger for my cell phone?

    I would not recommend charging the remote with a cell phone charger. You should know that cell phone chargers provide a voltage between 5 and 9 volts. The correct voltage is set with the stabilization card in the phone. The solar remote does not have a voltage regulator. If you connect the remote control to a charger, it may be damaged.

    How often should you change the battery in the Samsung Solar Cell remote control

    Samsung does not report the battery life of the remote control. However, from the experience of using batteries, it is likely to last about 5-7 years, but gradually the battery capacity will decrease. Nevertheless, thanks to the use of a solar cell for recharging, you will most likely not notice this.


    My Samsung solar remote doesn’t charge. It’s less than a year old. I plugged it into a type C charging cord which Samsung says is compatible and it still doesn’t charge. If I leave the remote pugged into the charging cord it will allow me to control TV functions. Any other thoughts. I guess I’m stuck with a remote that can’t be moved away from the cord.

    Most likely, either the battery is defective, which is unlikely, and most likely the battery charging (charging chip) is not working. It is unlikely that the battery is broken in a year, if it is, it will manifest in the fact that the battery has a 100% charge, but after 5-15 minutes the charge drops to 0%. In your case the battery is completely discharged, by plugging in the charger you apply voltage and the remote works. As an option, buy a new remote, or if you have the skills, you can disassemble it and see what happened. By the way the warranty on the remote control 3 months.

    I found that the solar remote is a gimmick, it never charges on sunlight or any source of light. I have got it even replaced. Did anyone have the luck ?

    My 2 month old Samsung TV control is already broken and will not change! Really disappointing as now it’s a useless TV unless you each download the app for your phone

    If you have an ordinary remote, replace the batteries, if Solarcell, charge it from the USB of the TV.

    Hi. Did you get an answer or able to figure this out? I’m having the same issue. I have a USB C charger for my iPhone but it doesn’t work. Thanks!

    The fact is that the remote control may not be charged by the iPhone charger. There are various iPhone chargers available, and they are designed for charging voltages from 5 to 9 volts. They have short-circuit protection as well as a regulator for the charging current level. Because the remote draws very little power, the charging current may be below the required level and the charger does not work, it thinks nothing is plugged in. Try plugging the cable into the USB port on the TV and charging the remote from the TV.

    Same solar panel is a joke. Wait until we have to heat our homes this way. Exactly! I have an Apple phone charger, but it wouldn’t fit.

    Review: IEsafy 26,800mAh Solar Power Bank

    Code: QC722VS7 5% coupon | Deal price: $17.09 | On Amazon

    Power banks come with all sorts of charging features, such as having low or high capacities and different charging speeds, and they can also have different designs. How you recharge a power bank is one of the most vital parts of owning one because you want an accessible way to recharge it. In this review, we’re looking at this IEsafy 26,800mAh solar power bank.

    Built-in solar recharging for a power bank sounds incredible, but let’s see how it performs and what other features this IEsafy power bank has.

    Power Capacity:

    This IEsafy power bank has a 26,800mAh capacity, and that’s a lot of power. With a 26,800mAh capacity, you can charge most phones to full power about four or five times. When it comes to charging, higher-end phone models such as the Samsung Galaxy S22 Ultra, which has a 5,000mAh battery, or the iPhone 14 Pro Max, which has a 4,323mAh battery, can charge to full power about three times with this power bank because they have much larger batteries.

    For charging tablets, you’ll be fair about one or two full charges, and for laptops, well, you can’t charge laptops with this power bank as the ports don’t supply nearly enough charging power, and there aren’t even any USB-C ports on it.

    Output Charging:

    The output ports could use some work on this power bank; however, the ports are alright for the price and the built-in solar panels you’re getting with this unit. That said, we still think that the lack of fast-charging ports is a big flaw, as nearly all portable phones and tablets are compatible with some sort of fast-charging technology.

    So the two outputs are two USB-A ports that each have a 5V/2.1A (10W), and the max output of the power bank is 5V/2.4A (12W). So if you’re charging a single device from one of the USB-A ports, then you can use the 10W from each port, but if you’re charging two devices simultaneously, then the 12W max output of the power gets split. Raising the max output to about 24W would have been better to make the most of the standard charging that this power bank features.

    Unfortunately, there are no USB-C ports on this power bank.

    Input Charging:

    You have two options to recharge this power bank: either use the Micro-USB input port or depend on the solar panels to solar recharge the power bank. The fastest way to recharge this power bank is to use the Micro-USB input with a 10W or higher wall charger. Yes, this power bank does indeed use a Micro-USB input directly charged from and not a USB-C port.

    The main reason to get this power bank in the first place is the four solar panels on this IEsafy power bank. The solar input of this unit is 6W, and that’s not a very fast speed. Still, if you’re looking for a power bank that can recharge without a wall charger, unfolding panels is quite nice because you have more sunlight hitting the panels, which leads to more constant charging rather than just having a single panel.

    If you’re camping or hiking and want a power bank that can charge without a wall charger, this IEsafy is a pretty good choice, but know that you’ll need a long sunlight exposure time for the panels.

    Size and Weight:

    When the solar panel is folded, this IEsafy power bank has a 6-inch length, a 3-inch width, and a 1.5-inch thickness. When the solar panels are fully unfolded, this IEsafy power bank has a 14-inch width. The charger weighs about 1 pound. So it’s possible to take this power bank anywhere with you.

    Functional Components:

    When using this power bank, the charging ports are under a covering, including the two USB-A output ports and the Micro-USB input port. A power button off to the side can be pressed to begin charging, showing the remaining capacity via the blue capacity indicators at the front of the power bank.

    Also, the power button activates the flashlight at the back of the power bank; hold down the button to turn on the flashlight. The flashlight has three settings: constant on, SOS, and flash mode, which can all be cycled through by pressing the button.

    Structure and Material:

    With the charging ports covered, this power bank has an IP65 water-resistant rating, which means it can withstand water splashes. It cannot withstand being submerged in water and will get damaged if done so. The overall build is good and feels like a solid product; however, be careful not to treat the foldable panels too roughly and not to damage the connections to the power bank.


    There’s not much to stay about the tech build of this power bank, as it doesn’t even feel warm when it comes to charging devices because the output is only 12W. The charger will get warm when you solar recharge it, but other than that, we didn’t find any technical build concerns.


    This IEsafy power bank is not reliable if you’re searching for a power bank with fast charging, like, at all. It does not feature fast output charging for your devices, and neither does it feature fast input charging. Those two things are big deal breakers for consumers looking for a power bank.

    This charger has solar recharging and a high capacity that can last quite a long time when it comes to charging phones. The solar recharging aspect will be most reliable if you can use the sun to recharge the unit.


    The 26,800mAh power capacity is pretty good for charging phones to full power multiple times, but the charging ports could use improvement. This power bank does not feature fast charging for the output or input ports. Solar recharging only maxes out at 6W of input power.

    The foldable solar panels are a great design choice, and there are power indicators for the capacity and the solar recharging—also, a LED flashlight with a few settings at the back of the power bank.

    The build quality of this power bank is good but nothing too special. Just be careful about not treating the foldable panels too roughly, as that could damage teh connections. When you have the ports covered, this power bank has an IP65 water-resistant rating which means that it can withstand splashes of water but cannot be submerged in water.
