Which Of These 7 Top-Rated Solar Power Battery Banks Is Best For You?
We have a power bank that will get you through a busy workday. And one that will help you survive days off the grid. Here’s a rundown of the 7 Best Solar Power Banks.
This behemoth of a battery pack is the best solar power bank on our list.
Four solar panels take advantage of your time outdoors. It operates off 15-watts, charging WAY FASTER than others. Some users said it only takes about 30 hours to charge their power bank using the panels fully. That’s a far cry from 100 hours with a single panel battery.
This QiSa Solar 35800mAh Power Bank also comes with a good quality LED flashlight. Do some night exploring or flash an SOS sign to save someone’s life. A multi-mode flashlight is a must for any trip into the great outdoors.
With 2 USB ports and a wireless charging pad, you can charge multiple devices at the same time too.
“With great power comes great responsibility.” In this case, you’re responsible for carrying this 1.5-pound battery. It’s also three phones thick. Enjoy the power!
If you want a power bank with the highest battery capacity, fast charging ports, and take days before you need to top up, the QiSa Solar 35800mAh power bank is right up your alley.
Our budget pick, the ADDTOP Solar Power Bank, does not skimp on the features. Unfold the pack, and bam! You have four solar panels to maximize solar charging. While you’re out draining your body’s energy, this solar power bank is charging itself. Just clip it to your backpack and trek away.
This 25,000mAh solar power bank can go from 0-100% in about two days under direct sunlight. The 5-watt solar setup still charges faster compared to those with only one panel. And hey, if you’re off the grid, any amount of power is better than none. Plus, with the LED light, you also get a light source.
The battery pack folds compactly. And looks sleek with the leather casing. It’s also water-resistant and shockproof so that it can handle the rough wilderness.
Pro tip: This can handle water spills, but it’s not cut out for swimming. Fold it up when you’re scaling a mountainside. The panels on their own can only handle a little drop, not a tumble down a cliff.
BLAVOR pulled out all the stops for their solar power bank. Check out what makes it our premium pick.
Let’s start with the detachable solar panels. Each one has 260mAh capacity – that’s a total of 1300mAh for the whole setup! You can fully charge your phone in 3 hours using the power of the sun. That’s awesome if you’re out on a weekend camping trip and run out of battery.
Now let’s say it’s Monday, and you start with the daily grind. You don’t need all those panels every day. Conveniently, the four sheets are only attached magnetically. You can just pop it out and store it in your glove compartment. Ta-da! Normal power-bank.
At 1.25 pounds, the BLAVOR Solar Power Bank is heavy. But remember, you’re taking 20,000mAh of power with you. It’s well worth it. Besides, you won’t need cables with you. Hello, wireless charging.
The BLAVOR Solar Power Bank is for the work-hard-play-hard individuals. Just snap the solar panels, and get an extra source of power when you’re out in the wilderness. Or, detach the 4-panels for everyday use. The choice is yours.
What’s more awesome than a solar power bank? A solar power bank with WIRELESS charging. No more struggling with forgotten or tangled cables. As long as your devices are Qi-enabled, you’re good to go.
This is a monster 30,000mAh battery pack. That’s enough juice to charge four devices at the same time. (Since it has 2 USB ports and 1 C-type plug-in.) Or you can charge your iPhone 11 times before the power bank dies. Perfect for traveling or if you’re the type that forgets to charge their devices before heading out.
Now let’s talk solar. The solar panel of this power bank is for emergency use only. It works, but very slowly. It’ll charge your phone to 50% after about 5 hours under the sun. That’s great for when you don’t have anywhere else to plug. But better stick with DC charging whenever possible.
The QiSa Solar Power Bank is the right solar power bank for you if you like to have different charging options. Compatibility isn’t an issue given all the ports and wireless features. But this chunky, rugged device clashes with a minimalist chic style.
Extreme adventurists will love the military-grade durability of the OUTXE Solar Power Bank. It’s not only shockproof but CRUSHPROOF as well.
This power bank is IP67 certified. It’s a cool term for being totally protected against dust. And it can handle being under 1 meter of water for 30 minutes (1).
This badass energy source stores 25,000mAh of power. It charges two devices at a time using the fast charging USB ports. And this can power up another Qi-adapted device wirelessly.
But wait, it gets better. The power bank itself charges from 0-100% in only 8 hours via 4A input. As for the 2A solar panel, well, it’s for emergency use. You’ll get to convert about 10% on your phone after 1 hour of sun time. It doesn’t seem like a lot. But that’s enough juice to call someone for help if you get lost or in trouble.
The OUTXE Solar Power Bank is the best choice for those who have a very adventurous, off-the-grid lifestyle. This hardcore power bank will keep up with all your activities and charging needs. It’s the perfect add-on to your outdoor gear.
This 10,000mAh battery pack doesn’t have a lot of extra juice, but It should keep you powered up for a whole day tucked away from civilization. Plus, it can charge three devices at the same time.
Speaking of being far away, the pack comes with two built-in flashlights that last 100 hours and a compass kit just in case you prefer to navigate the old-school way. How about charging?
The 180mA solar panel needs to bask for 60 hours to charge fully. Don’t go out with this battery, hoping to charge it on the way. The solar charger is just a backup. It can save you (just in case you’ve been trying to figure out the compass for a while and need a rescue).
The rugged construction and multiple charging modes are great for those that like to go hiking for a day. It’s an ideal phone charger or an emergency solar charger for your earphones and tablet.
Using PD 18W technology – some scientific ju-ju that manages high voltage – and a large 30,000mAh capacity, the Soluser Solar Power Bank safely charges your devices (including a laptop) at lightning speed.
Tech geeks will be happy with this solar charger. Aside from the Type-C port, it has three other USB ports for simultaneous charging. All the ports are Q3 fast charging. And we mean FAST. Fully charge an iPhone in less than an hour. You can check the status using the light indicators near the ports.
The solar panel holds 280mAh. It will charge your 3000mAh phone to near full after about 10 hours under the sun. That’s slow. But if you consider the power is free and comes out of nowhere, it’s amazing!
Leave no gadget behind when you have the Soluser Solar Power Bank. Its high capacity and PD 18W technology have enough juice to power up your phone, camera gear, and laptop.
Solar Power Bank Buying Guide
Getting a solar power bank can be overwhelming especially if it’s your first purchase of anything solar. Fret not! We’ve prepared a buying guide for you.
Here are the things you should consider when you’re choosing your solar power bank:
Count how many devices you use daily—phones, tablets, earphones. Round ‘em up, people. Check how much battery (mAh) each device has and list them down.
The total mAh value is the smallest capacity you need to supply daily.
Always choose a solar power bank with at least double the capacity you need. More capacity means less frequent charging.
Having more power means a longer charging time too. You want a high-capacity solar charger when you go off-grid for more than a day.
Now, if you just have a phone and a Bluetooth headset, that should be around 4,500mAh. Solar power banks like the 10,000mAh LEO WAY Solar Power Bank will last you two full charges for both devices. That’s roughly three days’ worth of regular use.
Charging time depends on the current. That’s the 1A, 2.1A, etc., that you see in chargers. Basically, the higher the current, the faster the charging time. But wait. Device traffic slows charging down (2).
“…there may be an overall maximum current output which will be shared between the outputs, slowing down the charging of the devices.”
Think of this as your WiFi speed. It has a maximum speed that gets slower when more people connect to it.
Some power banks solve this with fast-charging technology. It boosts the voltage to push more energy into the ports to charge at the highest current. All while making sure the power bank doesn’t explode. It’s pretty much magic to regular people.
The Soluser Solar Power Bank uses 18-Watt Power Delivery. That’s almost 4x more than usual-Powerful enough to charge a laptop.
Portability & Durability
A good outdoor solar charger needs to fit in your backpack. But the rule of thumb is the bigger the power, the heavier the bank. One pound of extra weight is a small price to pay for a whole lot of power.
It should also be rugged enough to handle a few falls, and it definitely needs to be water and dust-proof. There’s even a legit rating scale for this called the Ingress Protection (IP ratings).
The OUTXE Solar Power Bank tested as IP67. The second highest protection for devices. It means it’s completely dust-proof and can survive a soak for 30 minutes under 3 feet of water.
Solar power banks nowadays all have LED flashlights, especially those designed for outdoor use. It’s already a must-have when camping, so it makes sense to incorporate it into your solar power bank.
If you need extra light but don’t want to reduce power, try getting a solar lantern. It’s great for an extended camping trip.
Wireless charging means no more tangled cables. Or you don’t have to worry about forgetting them in the first place.
Most wireless chargers are Qi-adapted. It’s built-in tech that the latest models of most brands support. Think iPhone 8 Plus or Samsung S series generation (3).
Wireless charging is more convenient but also safer. Contrary to popular belief, waiting to drain your phone to zero before charging damages your phone (4). Going the wireless route extends your battery life by keeping your phone charged regularly. Also, no wires mean no damaged ports.
Solar Charging Time & Panels
One thing you have to understand is solar power banks take hours to fully charge in the sun.
That’s why most of them have direct power outlet changing. Plus, solar charging time can change depending on the number of solar panels, wattage, and battery capacity (5).
“Depending on the solar panel’s size and its rechargeable battery, the time to fully charge a solar power bank using only solar panels can range between 20 to 50 hours.”
Big capacity batteries need more solar power to charge faster. That’s why some have more than one solar panel.

Yes, you will need to charge a solar panel in direct sunlight to achieve maximum efficiency. But, it doesn’t mean you won’t be able to top up your power bank. Solar power banks will still charge even on cloudy days. They just take longer to charge than they would on a bright sunny day.
It will take 20-60 hours to charge a solar power bank, but it depends on the capacity, the solar panel’s watts, and voltage. Let’s use the QiSa Solar 35800mAh Power Bank as an example. It is rated at 10V, 15-Watts, and 35,800mAh. By using the watt-hours formula (Wh = Ah x V), it operates at 358wh. Now divide it by the wattage (15W). It will take 23.8 hours to charge in the sun.
A solar power bank can cost anywhere from 12 US dollars to over 100 US dollars. However, there are solar power banks with more expensive price tags. The more features you get, the more expensive it gets. More panels are especially pricey because of the build quality and all the tech that goes into it.
