The 10 Best Cheap Solar Power Bank Reviewed
1. Nuynix Solar Power Bank 20000mah
We put the Nuynix Solar Power Bank 20000mAh through its paces, and it offers a decent charge for its price point. The 20000mAh capacity is substantial enough to fully charge most smartphones multiple times. I appreciated the integrated wireless charging feature, which simplifies powering up compatible devices without fumbling for cables. The build feels solid, though the plastic casing does exhibit a bit of a sheen that attracts fingerprints.
The inclusion of multiple output ports is a definite plus, allowing for simultaneous charging of several gadgets. However, the “3”” in the name seems to refer to the screen size, which, while functional, is rather basic and not particularly bright in direct sunlight. Solar charging itself is a slow trickle, as is common with most power banks of this nature; don’t expect it to fully replenish the battery quickly.
This power bank is best suited for casual users who need a reliable backup for their phone on a day trip or a weekend getaway. It’s not ideal for heavy-duty, off-grid charging expeditions where rapid solar replenishment is a priority. If you’re looking for a simple, affordable way to keep your devices topped up with the convenience of wireless charging, it’s worth considering.
Pros
- Good 20000mAh capacity.
- Convenient wireless charging.

- Basic functionality.
3. Minrise Solar Power Bank 40000mah
The MINRISE Solar Power Bank 40000mAh is an absolute powerhouse, and for those hunting for the best cheap solar power bank, this one presents a compelling argument. The 40000mAh capacity is enormous, capable of keeping multiple devices charged for extended periods. I was impressed by the PD 20W fast charging support, which significantly speeds up recharging compatible smartphones. The unit has a robust, almost rugged feel to its construction, suggesting it can withstand some bumps and scrapes.
The solar panel on this unit is larger than many competitors, offering a more noticeable, albeit still slow, solar input. During our real-life usage scenario, we took it on a weekend camping trip. It easily powered our phones, a small tablet, and even a portable speaker throughout the trip, with the solar panel providing a small but appreciated trickle charge during daylight hours. The LED flashlight is surprisingly bright and useful for navigating in the dark.
However, the sheer size and weight of this power bank are considerable; it’s not something you’ll casually slip into a small pocket. The solar charging, while better than average for this category, still won’t fully recharge the massive battery in a reasonable timeframe. This is not for the minimalist traveler. If you need a high-capacity charger with fast-charging capabilities and appreciate the added solar benefit for extended trips, this is a strong contender.
Pros
- Massive 40000mAh capacity.
- PD 20W fast charging.

- Solar charging is still slow for full recharge.
4. Blavor Solar Power Bank 10,000mah
We tested the BLAVOR Solar Power Bank 10,000mAh, and it strikes a good balance between portability and features. The 10,000mAh capacity is ample for topping up a phone a couple of times, making it ideal for daily commutes or short trips. The 20W fast charging is a noticeable improvement over standard chargers, and the wireless charging adds a layer of convenience that’s hard to ignore.

I found the LED indicators to be clear and easy to read, even in bright light. The unit itself is not overly large, making it relatively easy to carry in a backpack or purse. However, the buttons for the flashlight have a slightly mushy feel, which isn’t a dealbreaker but is noticeable.
This BLAVOR is a solid choice for students, commuters, or anyone who wants a reliable portable charger with the added perks of wireless and fast charging. If you’re expecting the solar panel to be a primary charging source or to keep multiple devices powered for days without an outlet, this is not the product for you. It excels as a convenient, fast charging backup with a solar bonus.
Pros
- Good 10,000mAh capacity.
- 20W fast charging and wireless charging.
- Portable size.
- Clear LED indicators.
Cons

5. Soaraise Solar Charger Power Bank
Our evaluation of the SOARAISE Solar Charger Power Bank showed it to be a functional, no-frills option for basic power needs. The capacity, while not explicitly stated in the name, seemed adequate for a few phone charges. It feels decently constructed, with a matte finish that resists fingerprints well. The ports are straightforward, and plugging in cables felt secure. The overall design is utilitarian and focuses on delivering power.
The solar panel is a standard size for this type of device, and as is typical, its charging output is slow. We found that using the AC adapter is the most practical way to charge the power bank itself. The indicator lights are simple LEDs that show the general charge level, which is functional though not highly precise. It’s a bit on the heavier side for its apparent capacity, which was a minor surprise.
This SOARAISE power bank is best suited for individuals who need a backup charger for occasional use and aren’t looking for advanced features or rapid solar charging. If you require a high-capacity unit or plan to rely heavily on solar power for extended periods, you should look elsewhere.

6. Yelomin 38800mah Solar Power Bank
We put the YELOMIN 38800mAh Solar Power Bank through its paces, and for a budget option, it offers a substantial amount of juice. The sheer capacity is impressive, promising multiple charges for most smartphones. Its robust build feels ready for some outdoor adventure, with a textured grip that’s reassuring in hand. The dual USB-A ports are standard, but we found the charging speed to be adequate for topping up devices during a day hike.
The solar panel itself is present, as expected, but its effectiveness in truly charging the power bank is, frankly, minimal. It’s more of a trickle charge, best suited for maintaining a small amount of power or slowly replenishing after a long period of inactivity. We wouldn’t rely on it as a primary charging source in an emergency situation unless we had days of direct sunlight.
This power bank is ideal for campers, hikers, or anyone who spends extended time away from wall outlets and needs a reliable backup. It’s a solid companion for keeping your essential devices alive, especially if you can top it up from a wall charger before you leave. For those who prioritize capacity and ruggedness on a budget, this is a contender.
However, the charging indicator lights are a bit rudimentary, offering only a general sense of the remaining battery rather than precise levels. This can make it slightly difficult to gauge exactly when a recharge is needed. Also, the included carabiner feels a little flimsy, and we opted to use our own for attaching it to a backpack.
Pros
- Very high capacity for the price.
- Durable build quality.
- Good for extended outdoor use.
Cons
- Solar charging is very slow.
- Basic battery indicator lights.
- Included carabiner is weak.
7. Solar Power Bank 8000mah
When looking for the best cheap solar power bank, the 8000mAh model we tested offers a decent balance of portability and power. Its compact size makes it easy to slip into a pocket or small bag, and the 18W output means it can charge devices relatively quickly. We appreciated the solid, no-nonsense design; it feels well-constructed without any unnecessary frills. The single USB-C port for input and output is a welcome modern touch.
The solar panel, while present, functions as more of a supplementary top-up rather than a primary charging solution. It’s sufficient to provide a small boost if you’re caught out with no other options, but don’t expect it to fully recharge the bank. We found that even after several hours in direct sunlight, the battery percentage barely nudged.
This power bank is best suited for everyday commuters, students, or travelers who need a reliable way to keep their phone charged throughout the day. It’s not designed for extended off-grid expeditions but rather for those occasional moments when you’re away from an outlet. The 8000mAh capacity is enough for about two full charges of most standard smartphones.
One minor annoyance we encountered is that the glossy finish, while looking sleek initially, is a fingerprint magnet. It also lacks any form of water resistance, so we’d be hesitant to use it in damp conditions. For users who require rapid charging and a compact form factor, this is a good option, but those needing extensive solar replenishment should look elsewhere.
Pros
- Compact and portable.
- 18W fast charging support.
- Modern USB-C port.
Cons
- Solar charging is very slow.
- Glossy finish attracts fingerprints.
- No water resistance.
8. Solar Charger, 38800mah Solar Power Bank
This 38800mAh Solar Power Bank impressed us with its rugged, waterproof design, making it a strong contender for outdoor enthusiasts. The build quality is substantial, with rubberized edges and secure port covers that inspire confidence in its ability to withstand the elements. We found the multiple USB-A ports to be convenient for charging several devices simultaneously, although the shared output meant speeds dipped when all were in use.
While the solar panel is a nice feature, its practical charging output is limited. It’s best viewed as an emergency trickle charger to extend battery life slightly, rather than a means to fully recharge the massive 38800mAh capacity. We spent a good portion of an afternoon under direct sun and saw only a marginal increase in the battery indicator.
This product is ideal for hikers, campers, boaters, or anyone who needs a durable and high-capacity power bank that can handle less-than-ideal conditions. It’s a workhorse that provides peace of mind when you’re far from civilization. The large capacity means it can keep multiple gadgets powered for extended trips.
The charging indicator lights are a basic set of four LEDs, which provide a general idea of the remaining power but lack precision. We also noticed that the unit can get quite warm during heavy charging cycles, which, while not alarming, is something to be mindful of. If you need a robust power bank and don’t mind the slower solar recharge, this is a solid choice.
Pros
- Waterproof and rugged design.
- High capacity.
- Multiple USB-A ports.
Cons
- Solar charging is very slow.
- Basic battery indicator.
- Can get warm during use.
9. Errbbic Solar Charger Power Bank 20000mah
We evaluated the ERRBBIC 20000mAh Solar Charger Power Bank, and its inclusion of wireless charging is a notable feature at this price point. The matte finish feels pleasant to the touch, and the overall construction seems reasonably solid for everyday use. The 15W wireless charging pad is convenient for quick top-ups without fumbling for cables, though we found its placement required a bit of adjustment to ensure a good connection.
The solar panel on this unit is, as with most in this category, more for show than for substantial charging. It offers a very slow trickle charge that won’t significantly impact the 20000mAh capacity in any meaningful timeframe. We observed minimal gains even after extended periods in direct sunlight, so it’s best to rely on the USB-C input for primary charging.
This power bank is well-suited for tech-savvy individuals who appreciate the convenience of wireless charging and need a portable power source for their smartphones and other Qi-enabled devices. It’s a good option for daily commutes or short trips where you might not have access to a wall outlet for extended periods. The 20000mAh capacity offers a good number of charges.
One slight disappointment was the feel of the buttons; they have a bit of a mushy, less tactile response than we prefer. Additionally, while it has USB-C input, the output ports are only USB-A, which feels a bit dated. If you prioritize wireless charging and a decent capacity over fast wired charging or advanced features, this could be a good fit.
Pros
- Integrated wireless charging.
- Decent 20000mAh capacity.
- Matte, pleasant finish.
Cons
- Solar charging is extremely slow.
- Mushy button feel.
- Only USB-A output ports.
10. Solar Power Bank 20000mah
In our testing, the 20000mAh Wireless Portable Charger with a built-in solar panel presented itself as a competent, albeit standard, option for portable power. The unit feels fairly solid in hand, with a textured back that provides a good grip. The inclusion of wireless charging is a definite plus for convenience, allowing us to power up our devices without needing to search for cables, though precise alignment was sometimes tricky.
We must reiterate that the solar charging capability on this device is more of a supplementary trickle than a practical charging solution. Relying on the sun to significantly replenish the 20000mAh battery would require an impractical amount of time and consistent, direct sunlight. It’s best to view the solar panel as a minor power-saving feature rather than a primary charging source.
This power bank is a good choice for general users who want a reliable backup for their smartphones and other portable electronics, especially those who appreciate the added convenience of wireless charging. It’s ideal for short trips, long workdays, or any situation where you might be away from a power outlet and need to keep your devices topped up. The 20000mAh capacity is ample for multiple recharges.
The indicator lights are a simple four-LED system, which gives a broad indication of battery level but lacks the granularity we prefer for precise power management. We also found the unit to be a bit bulkier than some other 20000mAh power banks we’ve tested. If you’re looking for a basic, wireless-capable power bank and aren’t concerned with precise indicators or ultimate compactness, this is a decent pick.
Pros
- Includes wireless charging.
- 20000mAh capacity is sufficient.

Frequently Asked Questions
How Fast Do Solar Power Banks Charge?
Solar charging for power banks is generally slow. It depends heavily on sunlight intensity and panel size. Expect it to take many hours, even days, for a full charge from empty. This is best for topping up devices on the go.
It’s not a primary charging method for most users. You’ll likely still need to charge it from a wall outlet. Solar is more of a backup or emergency charging solution. Look for larger solar panels for slightly better performance.
Are Cheap Solar Power Banks Worth It?
Cheap solar power banks can be worth it for specific use cases. They are great as emergency backups or for light outdoor use. However, their solar charging capabilities are usually limited. Don’t expect them to replace your main charger.
For the price, they offer convenience and a bit of off-grid charging. If your expectations are realistic, they can be a useful addition to your gear. Consider them a bonus feature, not the main selling point.
What Is a Good Mah Capacity for a Solar Power Bank?
A good mAh capacity depends on your needs. For charging a smartphone once or twice, 10,000 mAh is often sufficient. For multiple charges or larger devices like tablets, consider 20,000 mAh or more.
Keep in mind that solar charging won’t significantly boost large capacities quickly. It’s more about the stored power. Balance capacity with portability and price. For a cheap option, 10,000-15,000 mAh is a common sweet spot.
Can I Rely on a Solar Power Bank in Cloudy Weather?
Reliance on a solar power bank in cloudy weather is minimal. Clouds significantly reduce sunlight intensity. This means the solar panels will generate very little power.
You might get a tiny trickle charge, but it won’t be enough to significantly charge your devices or the power bank itself. It’s best to have an alternative charging method available. Solar charging is most effective in direct, bright sunlight.
What Does Ip Rating Mean on a Power Bank?
An IP rating, like IP65 or IP67, indicates a device’s resistance to dust and water. The first digit refers to dust protection, and the second to water protection. Higher numbers mean better protection.
For example, IP67 means it’s dust-tight and can withstand immersion in water up to 1 meter for 30 minutes. This is vital for outdoor power banks. It ensures they can survive splashes, rain, or accidental drops near water.
Final Verdict
For the best cheap solar power bank, we recommend looking for a unit around 10,000-15,000 mAh with decent durability features. While the solar charging will be slow, it offers a valuable backup. Prioritize models with multiple USB-A ports and consider one with a built-in flashlight for added utility. Brands like Anker or RAVPower often have budget-friendly options that strike a good balance between price and performance, ensuring you get a reliable power source for emergencies and outdoor adventures without breaking the bank.
