The best solar chargers use the sun’s abundant power to keep your devices and batteries topped off. Solar chargers aren’t just for nature enthusiasts. Anyone who spends time away from an electrical outlet will find them helpful.
We recommend the X-DRAGON SunPower Solar Panel Charger for its 40W power output and high-efficiency cells. This charger doesn’t include a power bank to store all that juice, but if you are away from power and need to charge your phone or even your laptop, this is a great option. Opening the eight solar panels will give you plenty of power as long as there’s daylight.
X-DRAGON 40W Portable Foldable Solar Panel Charger
Our best overall charger can produce up to 40W of juice from its eight efficient panels. It opens wide to collect a lot of sunlight with eight high-efficiency panels, but it folds down small enough to fit into your backpack. There’s no water-resistance rating here, so be careful not to get caught in the rain, and no battery is included. But if you have large items that need a charge, the X-DRAGON SunPower Solar Panel Charger is a great choice.
You can plug in your phone and tablet, but you can also scale that up to your laptop with the five included different-sized barrel chargers and connection for your car battery. This is a great item to keep in your emergency car kit or your backpack for camping. The 18-month warranty will give you peace of mind too.
Number of Ports: 2 | Power Output: 2.8A max USB, 18V DC | Types of Ports: USB-A, DC | Number of Cells: 8 | Efficiency: 22 to 25% | Battery Capacity: N/A
BigBlue 28W Solar Charger
The Big Blue Solar Charger is a highly-portable solar charging solution that folds to a tiny 11.1 x 6.3 x 1.3 inches when closed. It’s long but narrow and thin, easily fitting into most backpacks. Included carabiners allow you to open and strap it to your bag outdoors.
There is no built-in battery, but the three USB-A ports allow you to charge any phone or tablet quickly. The panels are waterproof, which our reviewer tested by submerging the cells in a bathtub.
Our reviewer also noted that the advertised 28W output is misleading. There are four 7W panels which add up to 28 Watts. Unfortunately, the panels could output only around 17W maximum during our testing.
There’s a pouch for holding cables or devices while charging, which is a nice bonus. Given its water resistance, we’d recommend this for hikers and campers, even in inclement weather. Of course, cloudy days will mean less charging, but at least you know your panels can stand up to it.
Number of Ports: 3 | Power Output: 5V / 4.8A | Types of Ports: USB-A | Number of Cells: 4 | Efficiency: Not listed | Battery Capacity: N/A
What to Look for in a Portable Solar Charger
Solar power works best outside, so looking for water resistance in case you unexpectedly get caught in the rain or snow is a good idea.
Solar panels generate power, and that power has to go somewhere. If you have a solar panel and nothing plugged in, the panels will not generate energy, which is fine, but a battery would allow you to generate power and store it until you need it.
Keep in mind the kinds of devices you’ll be using. Most solar panels can do the job if all you need to charge is a phone or tablet. If you need to power something larger, such as a laptop or car, you’ll need a powerful setup to get the job done.
That depends mostly on the cells’ efficiency and the amount of sunlight you’re getting. Solar panels are getting more and more efficient these days, which means they’re capable of generating a lot of power. On a bright, sunny day, it’s not unreasonable to think you can generate enough power for a phone and tablet or even bigger items.
If it’s big enough, a solar panel can deliver a charge to your car’s battery to allow it to start. A jump start technically means you’re drawing from a power source to start your car right away. The solar option is more of a car battery charger, meaning you’ll need to wait some time for your car’s battery to charge before you can turn the key. But yes, it is possible.
Solar panels should never be left in a window or in a car to charge. The glass from the window can FOCUS with light on the panels and cause them to overheat. Solar panels are meant to be outside and under the sun, or put away.

For decades, “solar power” meant either large industrial facilities or bulky, expensive home arrays on a roof. But technology has come a long way, and solar power has become far more affordable. than that, you can now take solar power with you. Whether you’re camping, on a hike or simply out on the town for the day, there are plenty of great options for affordable portable solar chargers. These devices range from battery packs with integrated solar panels to suitcase-sized kits that offer more charging and battery capabilities. The smaller units are great for tossing in a backpack, while the larger ones will make a great addition to a day at the beach. Whatever your budget or needs, we’ve found the best five options on the market today.
- Blavor Qi Portable Charger : Best Handheld Solar Charger
- QiSa Solar Power Bank : Best Enhanced Handheld Solar Charger
- TopSolar SolarFairy : Best Compact Camping Solar Charger
- BigBlue Solar Charger : Best Charger for Long Hikes
- Jackery Solar Generator : Ultimate Solar Charger
This device is a tank. It is waterproof, dustproof and shockproof. You can toss it in a backpack or your trunk and never have to worry about it. Designed for camping and hiking, it includes two flashlights that work up to 164 feet away as well as an integrated compass and a clasp to hitch it to a backpack. In addition to USB and USB-C ports, the side opposite the solar panel is a Qi wireless charging pad. Make sure to charge before heading out, as this is more like a battery pack with additional solar capability (it could take several days to recharge on just solar). It has a 10,000-mAh capacity and provides six hours of power when fully charged.
- Multiple power points, including wireless charging pad
- Immensely versatile
- Takes a long time to charge on solar
- Rubber outlet cover may fall off over time
- Cannot solar charge and use wireless charging pad simultaneously
As we mentioned, the first item is more of a battery pack with additional solar capability. This solar power bank is larger, holds more charge and has additional solar panels, making solar recharging more viable when the battery is depleted. It can fully recharge in the sun in several hours, rather than days. In addition to the two USB ports, it has a wireless charging pad, which is on the same side as the solar panel. That means you can charge three items while the solar panels are deployed. Though it’s not as brutally rugged as the Balvor charger, it’s still waterproof, dustproof and shock proof.
- effective than single solar panel
- Enhanced capacity while still durable
- Built-in flashlight
- Cannot hike-and-charge
- Fold-out panels not as durable
- Using wireless charging pad obscures part of main solar panel
This is a serious solar panel system that packs up into the size of a laptop. With USB, USB-C and even DC 14.4V and 19V outputs, it can keep all your devices going for your camping trip or day at the beach. It also has a rack system that allows you to point the panels in the direction of the sun at all times, and anchors at each corner allow you to secure it in windy conditions.
- Legitimate instant solar power
- Compact storage
- Multiple outputs, including DC power
- Cannot charge while on the move
- Requires additional equipment for 19V power delivery
- Not as durable as handheld units
So you want legit charging capability, but you also want it while you’re on a long hike? And you want it to pack up so it fits almost anywhere? Guess you just want it all, huh? The Big Blue solar charger has three USB ports located in the same canvas pack into which the panels are stowed. It’s waterproof and the large corner anchors allow you to charge on the go or firmly secure it. This is the ultimate solar panel for truly roughing it.
- Flexible and foldable matt design
- Impressive charging rate
- No built-in battery bank
- No USB-C or 12V outputs
Not every camping trip involves backpacking to a remote region. For many, camping means loading up the family car and hitting a relaxing campsite with stoves and inflatable mattresses. This solar generator has multiple outlets, including USB, USB-C and AC wall-style outlets. Like a handheld solar device, this solar generator can be charged up before your adventure, but it’s not necessary for smaller items. When fully charged, you can power an electric grille, blender, coffee maker, laptop, mini-fridge and more.
- Massive capacity
- Multiple power outputs
- High-capacity (for portable) solar charging
- Heavy and bulky
- Requires pre-charging for best results
How Do I Know What Size Solar Charger I Need?
In order to determine which solar charger is right for you, you’ll need to think about how you plan to use it. Then you’ll have to compare the mAh (milliampere/hour) capacity of the charger with the mAh capacity of the batteries in the devices you plan to charge. For example, if your solar charger has a capacity of 20,000 mAh and your cell phone’s battery has a capacity of 5,000 mAh, when you divide the charger’s capacity (20,000) by you cell phone battery’s capacity (5,000), you see that you can charge that phone four times total (20,000/5,000 = 4). The higher the mAh of your solar charger, the more energy it can store, and the more devices it can charge. Keep in mind that a higher mAh does not equal a faster charge time. That depends on the amperage and voltage of the solar charger (the higher the output, the faster the charge), as well as the charging circuit inside the device you are charging.
The team at Forbes Wheels is out there in the real world, just like you. When we’re not on deadline, we camp, go on road trips and head out to the beach. We have real-world experience in keeping our phones and laptops fully charged at all times, and have some direct experience with devices just like these. We combined this real-world experience with the expansive selection of user product reviews and ratings to bring you an accurate snapshot of these products.
It all depends. The small handheld chargers could take days, and so they require pre-charging the battery pack. For a compact battery and a fold-out panel, it could take three hours to charge. The same issues arise when you scale up, and so without pre-charging, a solar power bank could take days in direct sunlight to fully charge.
Even a small solar charger can power up your mobile phone between five and 10 times. It all depends on the battery size. A handheld device is perfect for a few people looking to keep their phones fully charged. The standalone fold-out panels work as long as you’ve got them deployed.
Technology is improving all the time, but it often comes down to the quality of the manufacturer. Reports vary wildly, from three to 20 years. For the smaller, more affordable options, it’s likely closer to a handful of years. Expect about 80 percent of the stated life by the manufacturer.
Yes. Though most effective in direct sunlight, the panel can still capture energy when it is overcast. They can also capture some residual energy when you are in the shade or if you are in indirect sunlight. They will even work by capturing light from a lamp at home, but at that rate, you should use the power input to charge its battery pack from a wall outlet.
Some of these products have a one-year warranty. Others have a two-year warranty. Some do not have a warranty at all. For the more expensive products, it may be possible (and recommended) to buy an extended warranty.
DIY Solar 12V Car Battery Charger: 4 Steps (w/ Video)
Just so you know, this page contains affiliate links. If you make a purchase after clicking on one, at no extra cost to you I may earn a small commission.
I recently made a DIY solar car battery charger.
The circuit has auto cut-off to prevent overcharging the battery. And you can use whatever size solar panel you want depending on whether you want a fast charge or a slow trickle charge.
Here’s a 60-second video I made showing how I built this project. Check it out below and consider subscribing to my YouTube channel for more DIY solar videos like this!
- 12V car battery — or just a standard 12V lead acid battery
- Renogy Wanderer 10A charge controller — or any cheap PWM charge controller
- 12V solar panel — I used a 5W 12V solar panel for a slow trickle charge. I’d use a 20W 12V solar panel or greater for a faster charge.
- Wires, connectors, and fuses — I used the NOCO GC018 12V adapter, which comes with ring terminals. If you want battery clamps, use the NOCO GC017.
- MC4 adapter cables — Needed if your solar panel has MC4 connectors. These aren’t needed for the 5W and 20W panels linked above.
- NOCO battery box (optional)
- Wire cutter
- Wire stripper
- Drill (optional)
Step 1: Connect the Car Battery to the Solar Charge Controller
I used the NOCO GC018 to make it super easy to connect my 12V battery to my solar charge controller. (the GC018 is a 12V plug adapter that comes with an inline fuse and ring terminals.)
First, I cut off the 12V plug socket with my wire cutters. Snip, snip!
Then I peeled the wires apart and stripped them with my wire strippers.
Just like that, my “battery cables” are ready. I can now connect charge controller and battery.
To do so, I connected the positive and negative ring terminals to their respective battery terminals. Red to red, black to black! (I also swapped out the inline fuse for the right fuse size given my solar panel wattage.)
Then I connected the stripped wire ends to the battery terminals on my solar charge controller.
My solar charge controller turned on, indicating it was properly connected to the battery.
At this point, consult your charge controller’s manual to see if you need to program it for your battery’s chemistry. Mine defaults to sealed lead acid, which is the type I was using.
Step 2: Connect the Solar Panel to the Solar Charge Controller
Connect the solar panel wires to the solar panel (PV) terminals on your charge controller.
Note: If your solar panel has MC4 connectors, you’ll have to use MC4 adapter cables to be able to connect it to your charge controller.
Now the solar panel is connected to the 12V battery via the solar charge controller.
Here’s what mine looked like:
This means my solar car battery charger is complete!
Yep, that’s all there was to it.
Time to test it and see if it works…
Step 3: Test Your Solar Car Battery Charger
To test my solar car charger, I simply took the solar charger outside and put the panel in direct sunlight.
Then I looked at the PV current display on my charge controller. It read 0.2 amps, meaning my solar panel was in fact charging my 12V battery.
Technically my solar car battery charger is done. I can just leave the panel out in the sun and the charge controller will cut off the charging when the battery is full.
That’s right — this solar 12V battery charger has auto cut-off built right in. Pretty cool.
If I want to solar charge the battery while it’s in my car, I can just put the solar panel and charge controller on the hood of my car.
But I decided to take it one step further…
Step 4: Make Your Solar Car Charger Look Nice (Optional)
I picked up a NOCO battery box and plopped my 12V battery right inside.
Then I used a drill and the mounting screws included with my charge controller to mount the controller to the top of the battery box.
Next, I drilled some holes in the top of the box to feed the battery cables through.
Tip: Drill the holes angled slightly away from each other so the leads won’t touch when fed through the lid. You don’t want to short the battery!
Then I reconnected everything…
I’m happy with how it turned out. The box makes the whole system more portable and cuts down on cable clutter. It also looks nicer.
DIY Solar Car Battery Charger Circuit Diagram
Here’s the circuit diagram for a solar 12V car battery charger with auto cut-off.
And here’s what it looks like when built:
- Safety best practices are to place a fuse between the charge controller and both battery and solar panel
- For most charge controllers, you connect the battery first and then the solar panel. Consult your controller’s manual for the manufacturer’s recommended connection order.
- Make sure to get a 12V solar panel and 12V charge controller for your 12V car or lead acid battery
- I recommend a PWM charge controller because it’s a lot cheaper
Tip: This solar charging circuit diagram would work for any battery chemistry and voltage as long as you got a compatible charge controller and solar panel.
How Long Does It Take to Solar Charge a Car Battery?
A typical car battery is a 12V lead acid battery with a capacity of around 50 amp hours (Ah).
Knowing this, we can use our solar battery charging calculator to estimate how long it’d take to fully charge a depleted car battery using a PWM charge controller.
Here are the estimated charge times for 5 common solar panel sizes:
- 5W solar panel: 107.3 peak sun hours
- 10W solar panel: 54.1 peak sun hours
- 20W solar panel: 27.6 peak sun hours
- 50W solar panel: 11.6 peak sun hours
- 100W solar panel: 6.3 peak sun hours
A 5W or 10W solar panel is a good size to pick for a slow, trickle charge. Some people use these sizes to keep their car, camper, or RV battery topped up when not in use.
Want to solar charge your car battery in a week or less? Go with a 50W or 100W solar panel.
You could also make your charger faster by swapping out a PWM charge controller for an MPPT charge controller. MPPT charge controllers are much more efficient.
Add-ons and Upgrades
Here are a couple ideas for making your car battery solar charger even nicer:
- Add suction cups for attaching the solar panel to inside to your windshield: I’d recommend doing this with a 10W panel. Solar panels work behind glass, but with a reduced output. A 5W panel behind a windshield might not output a high enough voltage to charge the battery.
- Add a 12V plug to charge the battery through the 12V socket: Some car batteries can be charged through the 12V socket inside the car. Instead of connecting the solar charge controller directly to the battery, you could connect it to a 12V “cigarette lighter” plug and then put the plug in the 12V socket. Just remember not to connect the charge controller to the solar panel until you’ve connected it to the battery.
DIY Solar Chargers You Can Build Now
You know how to solar charge a car battery…
…why not try building solar chargers for the other batteries and electronics in your life?
Here are two more solar charging project ideas for you:
Solar Electric Bike Charger

Portable Solar Panel for an Electric Car
Charging your brand-new electric car at a charging station can be expensive and at times inaccessible.
Having the ability to harness the sun’s energy and power your devices using a solar panel is one that’s being used by an increasing amount of people. But with such power, could you use a portable solar panel to charge your electric car?
We discuss whether portable solar panels can be used as a way to provide power to your electric vehicle.
Portable Solar Panel for Electric Car
Why Use Portable Solar Panels
Solar panels are becoming a go-to method of powering your devices in different situations using the sun’s natural energy. The minute you opt for a fuel generator and suddenly run out of gas, that’s another expense and another item to lug around.
You don’t need to worry about fuelling up the portable solar panel. If the sun is shining, anything being connected to your solar panels will receive power.
Portable solar panels allow you to power up your devices and appliances most cleanly and quietly possible. They are mobile and easy to use, giving them the ability to generate power on the go.
If you plan on going on a lengthy road trip with your trusty RV, having a foldable solar panel for camping on standby will be beneficial to everyone. That way, you can ensure that all appliances can be charged if the sun is shining.
There are various situations, from recreational to preparing for a disaster, where a portable solar panel will prove useful.
However, you seek the answer to a different million-dollar question. If portable solar panels can charge everything from a mini-fridge to a cell phone, are they powerful enough to charge a vehicle? specifically, an electric car.
Can You Use a Portable Solar Panel to Charge an Electric Car
Before we can answer this question, we need to understand why it would even be considered as an option.
Many vehicle manufacturers are taking the electric route in terms of how cars are being powered.
Not only is this better for the environment due to lower carbon emissions, but you are now able to charge your car as if it were an appliance. However, this comes with a downside.
As more electric cars are being produced, more charging stations are needed.
Since there’s an insufficient amount of charging stations, people are being forced to charge their electric cars with electricity from coal and nuclear power plants.
This isn’t a clean way to go about charging your vehicle.
Another option that isn’t exactly green is using a wall outlet at home to charge your electric car. This method is slow and expensive.
Also, standard household plug points aren’t designed to use so much power for such a long period.
Clean Energy for Electric Cars
The best and cleanest solution to charging your electric car is indeed using a portable solar panel. What makes this the cleanest solution is providing 100% renewable and natural energy to your electric car.
Using a solar panel to charge your electric car is an independent and affordable solution. You won’t need to worry about price increases from power companies. Your only concern is if there’s enough sunlight in a specific area.
The most important factor to take into consideration is how much power an electric car uses and needs to fully charge.
For example, making use of a 200 W solar panel hooked up to a portable 100 watt-hour generator will take 8 hours to get about 8 miles worth of driving.
Having a portable solar panel to charge your electric car serves as an emergency charging station should you not be near any other sources of charging.
However, if it’s bright out and you wish to add some juice to your electric car, making use of a portable solar panel will do the job.
This answers the question of whether a portable solar panel can charge an electric car. It certainly isn’t the most efficient way to charge your vehicle, but it’s the cleanest and most affordable.

The 10 Most Practical Solar Car Battery Chargers Of 2023
A portable solar car battery charger uses solar energy as source of power. There are many advantages of solar power over conventional power sources like fuel because solar energy is clean. This means that it does not pollute the environment.
What’s more, solar energy is free once the installation costs have been met. To convert sun rays into useful power, one needs a solar panel. This principle is no different when it comes to solar car battery chargers.
Why Solar Car Battery Charger is the Best Option
Most solar-powered chargers charge slowly which is a good thing right? Yes right. You see, when a battery charges too fast, a lot of heat is generated which reduces the shelf life of the battery. In extreme cases, Rapid high-voltage charging may cause the battery to explode.
As earlier mentioned, solar chargers use the sun which is readily available, and you will not need any specialized equipment to charge your battery. This makes charging your battery very easy and convenient. The case is different with an electric charger as you would have to look for a power source to do the charging. Let’s have a look at the 10 best solar car battery chargers.

How Does Solar Car Battery Charger Work?
The portable solar car battery charger uses the sun as its source of power. Usually, the charger has a solar panel that is portable, and you can place it on the dashboard or the roof of your car. Regardless of where you place it, make sure there is enough exposure to sunlight. The solar panel converts the sun rays to DC which charges the car’s battery. The charger comes with alligator clips which you clip to the terminals of your battery. You can also charge your battery through the cigarette lighter port in your car.
There are usually two types of solar car chargers that are on the market. The first solar charger has a regulator which controls the charge that goes into the battery. The advantage of the regulated solar charger is that it prevents overcharging of the battery. The regulated battery chargers are used to ensure that your car battery does not drain when you leave the car for long periods of time. The second type of solar charger does not have a regulator.
Features of The Solar Car Battery Charger
Prevent Overcharge or Discharge of Your BatteryAny solar car charger worth its salt should come with a mechanism to prevent your battery from overcharging or discharging. Some have a regulator that prevents overcharging. For other brands, you have to set the current that you want to flow into your battery.
Ample-sized wires and connectorsYou might find yourself in a situation where you need to move the solar panel of your charger a long distance. A charger that comes with long wires and connectors is very ideal for such situations. The long wires will enable you to place the panels in the optimum position.
High Powered chargersThere are solar power panels that have a high resolution and can convert light to power even in an overcast sky. Ideally, all solar panels can do so, but their power output is greatly reduced. You should buy solar battery chargers that are designed to work in low-light situations.
Benefits of The Solar Car Battery Charger
One of the greatest advantages of the solar car battery charger is its portability. You practically move with it wherever you go and can charge your car battery on the move. Another advantage is that the charger does not require an external source of energy, unlike the electric charger. This makes it cheaper since you do not incur additional electricity costs.
With proper usage and maintenance, the charger is guaranteed to give you service for a long period. Since you can use the cigarette port to charge your battery, you need not worry about fixing the alligator clips to the battery terminals- just plug the charger in ad off you go!
The portable solar car battery charger is not only effective, but they are also efficient. With the ease of portability and use, it makes sense to grab one for yourself. With a solar car battery charger, you no longer have to worry about your car not starting due to a low battery.
