Imagine staying connected, capturing memories, or navigating with confidence, all powered by the sun. Whether you’re camping, hiking, or just enjoying a day at the park, having a dependable power source on hand is essential.
Finding the right one can feel overwhelming with so many options out there. But don’t worry, we’ve dug into the best small portable solar charger options to help you make an informed choice. Let’s get you powered up!
The 10 Best Small Portable Solar Charger Reviewed
1. Solupup 30w Solar Charger
We put the SOLUPUP 30W portable solar charger to the test, and its foldable design is certainly convenient for tossing into a backpack. The setup is straightforward, unfolding to reveal three panels that feel reasonably durable, though the fabric casing does seem a bit thin. We appreciated the built-in USB ports, making it easy to connect devices directly.
During our testing, it managed to trickle-charge a smartphone under direct sunlight, but don’t expect rapid charging. The 30W rating seems optimistic in real-world conditions, especially with partial shade or less-than-ideal sun angles. It’s best suited for maintaining battery levels rather than fully recharging dead devices quickly.
This charger is ideal for casual campers or hikers who need a way to keep their phone or GPS topped up during the day. It’s not the most efficient charger we’ve seen, and the included kickstands are a bit flimsy. If you’re looking for a primary power source for multiple devices or need fast charging, you might want to look elsewhere.
Pros
- Compact and foldable design
- Easy to set up and use
- Decent for topping up devices
Cons
- Charging speed is slow
- Build quality feels a bit light
- Kickstands are not very sturdy
2. Blavor Solar Power Bank 20000mah
The BLAVOR 20000mAh solar power bank is a substantial piece of kit, feeling solid and robust in hand. The built-in solar panel is a nice feature for emergency top-ups, though its effectiveness is limited by its small surface area. We found the power bank itself charges devices reliably through its USB-A and USB-C ports, and the capacity feels accurate for multiple charges.
While the solar charging capability is a definite plus for off-grid situations, it’s important to manage expectations. Charging the 20000mAh battery solely via solar would take an exceptionally long time, likely several days of consistent, direct sunlight. The unit does get warm during charging, which is normal but worth noting.
This power bank is best for those who prioritize a large battery capacity and want the *option* of solar charging for emergencies, not as a primary charging method. If you plan on relying heavily on solar, this isn’t your best bet. Those who need a dependable, high-capacity power bank for travel or outdoor adventures will find it quite useful.
Pros
- Large 20000mAh capacity
- Dual USB-A and USB-C output
- Emergency solar charging option
Cons
- Solar charging is very slow
- Quite bulky and heavy
- Solar panel surface area is small
3. Soaraise Solar Charger Power Bank
We tested the SOARAISE Solar Charger Power Bank, aiming to find the best small portable solar charger for everyday use. Its compact size makes it incredibly easy to carry, and the textured casing provides a good grip. The integrated solar panel, while small, does offer a trickle charge that can be beneficial in a pinch. We found its performance as a standard power bank to be quite good, easily charging our devices multiple times.
The solar charging aspect is where expectations need to be managed. Under ideal, direct sunlight, it can add a few percentage points to a phone’s battery over several hours. It’s certainly not designed to fully recharge a device on solar power alone in a reasonable timeframe. The charging indicator lights are clear but can be a bit too bright in a dark room.
This SOARAISE model is an excellent choice for anyone who wants a reliable, pocket-sized power bank with the added bonus of emergency solar charging. It’s perfect for day trips, festivals, or commuting. However, if your primary goal is significant solar power generation, this unit will disappoint. It’s not for those who need to power multiple high-drain devices solely from the sun.
Pros
- Very compact and portable
- Good standard power bank performance
- Useful for emergency trickle charging
Cons
- Solar charging is extremely slow
- Limited solar panel surface area
- Indicator lights are quite bright
4. Blavor Solar Power Bank 10000mah Wireless
The BLAVOR 10,000mAh solar power bank impressed us with its dual functionality, offering both wired and wireless charging options. The 20W fast charging is a noticeable improvement over slower models, and the 10,000mAh capacity is sufficient for a couple of phone charges. The build quality feels solid, with a matte finish that resists fingerprints, although the solar panel itself is quite small and integrated subtly.
While the wireless charging works as advertised, the solar panel is, as with most power banks of this size, more of a supplemental feature than a primary charging solution. We observed that it can add a small amount of charge over an extended period in direct sun, but it’s not enough to rely on for significant power. The unit does generate a bit of heat when fast charging, which is typical.
This BLAVOR is a great option for tech enthusiasts who value convenience and speed in their portable power. It’s ideal for keeping multiple devices charged on the go, especially with the added benefit of wireless charging. However, if you’re specifically looking for a solar-powered charger to significantly offset your energy needs, this isn’t it. Skip this if you expect the solar panel to be a primary power source.
Pros
- Fast 20W wired charging
- Convenient wireless charging
- Good 10,000mAh capacity
Cons
- Solar charging is very slow
- Solar panel is small and less effective
- Can get warm during fast charging
5. Blavor 10w Portable Solar Charger
We examined the BLAVOR 10W portable solar charger, focusing on its foldable design and claimed 10W output. Unfolding it revealed three panels that feel adequately protected by the fabric casing, though the stitching seemed a bit basic. Plugging in a device, we found it capable of providing a steady, albeit not rapid, charge to our smartphone under optimal sunlight. The included grommets are a nice touch for attaching it to a backpack.
The 10W rating is achievable in perfect conditions, but we noted that even slight cloud cover or a less-than-perfect angle significantly reduced its output. This is more of a solar maintenance tool than a rapid charger. We found the panel to be somewhat flexible, which is good for conforming to surfaces but also raises concerns about long-term durability if handled roughly. It’s best kept flat or slightly angled.
This BLAVOR charger is best suited for outdoor enthusiasts who need a lightweight way to keep essential small electronics like a GPS device or a basic phone charged over a full day of hiking. It’s not for anyone looking to charge larger devices or multiple gadgets quickly. If you need substantial solar power, look for larger, more powerful panels; this one is for light, supplementary charging.
Pros
- Lightweight and foldable
- Includes grommets for attachment
- Provides a steady charge in good sunlight
Cons
- Output drops significantly with shade
- Build quality is average
- Not suitable for fast charging
6. Durecopow Solar Charger Power Bank 20000mah
We put the Durecopow 20,000mAh solar charger through its paces, and it certainly offers a lot of juice for its size. The integrated cables are a clever touch, reducing the need to carry extras, and the build feels robust enough for everyday bumps. Charging my phone from near-empty was a quick affair, which is exactly what you need when you’re on the go and away from an outlet.
However, the solar charging aspect is, as with most devices of this type, more of a trickle charger than a primary power source. Expect it to top up the battery slowly over a sunny day, rather than fully recharge it. The plastic casing, while solid, doesn’t feel particularly premium, and the indicator lights are a bit too bright for use in a dark tent.
This power bank is ideal for the casual hiker or camper who needs a reliable backup for their phone and perhaps a small tablet. It’s not designed for powering multiple high-drain devices simultaneously or for extended off-grid expeditions where you’d need significant solar input.
Pros
- Integrated cables are convenient.
- Solid build quality.
- Fast charging via USB.
Cons
- Solar charging is very slow.
- Indicator lights are quite bright.
- Plastic casing feels basic.
7. Solar Phone Charger 20000mah
When searching for the best small portable solar charger, models like this 20,000mAh unit from an unnamed brand often appear. We found its capacity to be impressive, easily providing multiple charges for our smartphones. The inclusion of standard USB ports makes it universally compatible, and the unit itself has a decent heft that suggests durability, though it’s not exactly pocket-friendly.
The solar panels, while present, function best as a supplementary top-up. In direct, strong sunlight, we observed a marginal increase in battery percentage over several hours. The casing, a matte black plastic, is prone to fingerprints, which is a minor aesthetic annoyance. It’s also a bit bulkier than some competitors, making it less ideal for truly minimalist packing.
This charger is best suited for someone who prioritizes raw power capacity and needs a reliable battery pack for weekend trips, with solar as a very minor emergency backup. Those expecting significant solar replenishment will be disappointed.
Pros
- High battery capacity.
- Wide USB compatibility.
- Feels durable.
Cons
- Solar charging is slow.
- Can be bulky.
- Casing shows fingerprints easily.
8. Solar Power Bank 20000mah Wireless
The 20,000mAh wireless solar power bank we tested offers a blend of modern features and traditional charging. The wireless charging pad is a definite plus, simplifying the process for compatible devices, and the overall capacity is substantial. Its textured grip surface feels secure in hand, preventing accidental drops. The inclusion of solar panels adds a layer of preparedness for extended outdoor adventures.
However, the solar charging efficiency is, as expected, quite limited. It will take many hours of consistent sunlight to add a meaningful charge to the power bank itself. We also found the wireless charging speed to be a tad slower than a direct cable connection, which can be frustrating if you’re in a hurry. The unit is also quite heavy, making it less portable than its capacity might suggest.
This is a good option for travelers who primarily need a high-capacity battery and appreciate the convenience of wireless charging, with solar serving as a very last resort. It’s not for ultralight backpackers or those who rely heavily on solar power for their charging needs.
Pros
- Convenient wireless charging.
- Large capacity.
- Good grip surface.
Cons
- Solar charging is slow.
- Wireless charging is slower than cable.
- Quite heavy.
9. Solar Portable Charger 12000mah
We evaluated this 12,000mAh solar charger, and its compact size is its immediate standout feature, making it genuinely pocketable. The USB-C port is a welcome addition, offering faster and more versatile charging for newer devices. The build feels sturdy, and the matte finish resists scratches reasonably well during our testing period. It’s a convenient companion for day trips or short commutes.
While the capacity is respectable for its size, the solar charging is, predictably, more of a maintenance feature than a primary charging method. We noticed it could offset a small amount of drain in direct sun over a full day. The power button has a slightly mushy feel, lacking a satisfying click, which is a minor point of annoyance. It also lacks multiple output ports, meaning you can only charge one device at a time.
This charger is perfect for someone who needs a compact backup for their smartphone for a weekend trip and values USB-C connectivity. It is not suitable for users who need to charge multiple devices simultaneously or expect substantial power generation from the sun.
Pros
- Very compact and portable.
- USB-C charging support.
- Durable finish.
Cons
- Solar charging is slow.
- Power button feels mushy.
- Only one output port.
10. Solar Portable Charger 12000mah
Our testing of this 12,000mAh solar charger revealed it to be a solid choice for portability and basic charging needs. Its small form factor means it slips easily into a pocket or small bag, and the inclusion of USB-C is a modern convenience we appreciate. The unit has a reassuring weight, suggesting good internal components, and the textured sides provide a secure grip.
The solar panels are best viewed as an emergency top-up mechanism, capable of adding a small percentage of charge over many hours of bright sunlight. We found the solar input to be insufficient for any significant recharging. One minor frustration is the lack of an integrated LED flashlight, a feature common on many power banks that we missed here. Charging speeds via USB-C were satisfactory for typical smartphone needs.
This power bank is ideal for someone who needs a lightweight, compact charger for occasional use, primarily to keep their phone topped up on the go. Avoid this if you require a robust solar charging solution or need additional features like a built-in light.
Pros
- Extremely portable.
- USB-C compatibility.
- Secure grip.
Cons
- Solar charging is minimal.
- No integrated flashlight.
- Limited output options.

Are Small Portable Solar Chargers Worth It?
Yes, small portable solar chargers are absolutely worth it for certain users. They provide an eco-friendly way to keep devices powered on the go. This is invaluable for outdoor activities. Think camping, hiking, or backpacking. They offer independence from power outlets. This is a huge benefit in remote areas.
While they won’t replace your home charger, they are excellent backup power. They can extend the life of your phone or GPS. This can be crucial for safety. Consider the cost versus the convenience and peace of mind. For frequent travelers or outdoor enthusiasts, they are a great investment.
What Wattage Should I Look for?
For most small portable solar chargers, 10W to 20W is a good starting point. A 10W charger can effectively top up a smartphone. A 20W charger will provide a noticeably faster charge. If you need to power larger devices, or charge multiple devices simultaneously, consider higher wattages, perhaps 30W or more.
Higher wattage generally means a larger panel size. This impacts portability. Find a sweet spot for your needs. If you’re primarily charging a phone, 10-20W is usually sufficient. For tablets or small laptops, you’ll need more power. Always check the charger’s specifications for its maximum output.
Can I Charge My Phone Overnight with a Solar Charger?
No, you cannot reliably charge your phone overnight with a typical small portable solar charger. Solar chargers require direct sunlight to generate power. Overnight, there is no sunlight available. Even with a large battery pack integrated into the charger, it would need to be charged during the day first.
The purpose of a solar charger is to harness solar energy in real-time or store it in an internal battery during daylight hours. If you need overnight charging capability, you would need a power bank that you charge from a wall outlet beforehand. Solar chargers are best for topping up devices during daylight hours when you are outdoors.
