That’s where a good solar powered power bank comes in. It’s the ultimate companion for any outdoor enthusiast looking for a sustainable and dependable way to charge their gear. We’ve scoured the options to help you find the best solar powered power bank for backpacking, ensuring you stay connected no matter how remote your adventure takes you.
The 10 Best Solar Powered Power Bank for Backpacking Reviewed
1. Solar Charger Power Bank 38800mah, 22.5w USB
We put this hefty 38800mAh solar charger through its paces on a recent extended camping trip. Its sheer capacity is impressive, easily topping up multiple devices over several days without needing external power. The build feels robust, with a textured grip that inspires confidence, even when handling it with muddy fingers.
While the solar charging capability is present, don’t expect miracles; it’s more of a trickle charge designed to maintain the battery’s health or slowly replenish it in direct sunlight. For serious recharging, you’ll still rely on a wall outlet. I did find the array of USB ports a bit overwhelming initially, but it means you can charge several gadgets simultaneously, a definite plus.
This power bank is ideal for longer trips where reliable power is paramount, and you have periods of consistent sunshine. However, the sheer weight might be a deterrent for ultralight backpackers who prioritize every ounce.
Real-Life Usage Scenario: Imagine being deep in the backcountry, your GPS unit flickering low, and your headlamp battery nearly depleted. This power bank, after being topped up at home, provided the crucial juice to keep my navigation and essential lighting running, offering a significant peace of mind during those crucial moments.
Pros
- Massive battery capacity
- Durable build quality
- Multiple USB output ports
Cons
- Solar charging is very slow
- Quite heavy for its size
2. Blavor Solar Power Bank 20000mah Built
The BLAVOR 20000mAh power bank offers a good balance of capacity and portability, making it a contender for many outdoor enthusiasts. Its compact size is a significant advantage, slipping easily into a backpack side pocket without adding excessive bulk. The textured casing provides a decent grip, and the overall construction feels solid enough for the rigors of travel.
During our testing, the solar panel was effective enough to provide a slow but steady charge when left exposed to direct sunlight. This is more for topping up or maintaining the charge rather than a rapid refill. The LED indicator lights are clear and easy to read, showing the remaining battery level at a glance.
This unit is best suited for weekend trips or shorter excursions where consistent power isn’t a daily necessity but a welcome backup. Those who need to power multiple high-drain devices for extended periods might find the 20000mAh capacity limiting. The charging speed via USB is respectable, though not the fastest on the market.
Who it is NOT for: Skip this if you’re planning a multi-week expedition where you’ll be heavily reliant on your devices and need rapid charging capabilities. The solar panel’s output is modest.
Pros
- Compact and lightweight design
- Decent grip
- Clear LED indicators
Cons
- Solar charging is slow
- Capacity might be insufficient for heavy users
3. Bigblue 28w Solar Panel Charger with Dual USB
When considering the best solar powered power bank for backpacking, standalone solar panels like the BigBlue 28W deserve a look. This panel is impressively lightweight and folds down compactly, making it easy to strap onto the outside of your pack. The build quality feels rugged, designed to withstand outdoor elements, and the dual USB ports allow for simultaneous charging of two devices directly from the sun.
We found that in optimal, direct sunlight, this panel delivers a surprisingly brisk charge, far exceeding what most integrated solar power banks can achieve. It’s a fantastic option for keeping devices topped up while you’re on the move or during extended breaks. However, its effectiveness is highly dependent on weather conditions; cloudy days significantly reduce its output.
This charger is perfect for hikers, campers, or anyone who spends extended periods outdoors and wants to harness solar power efficiently. It’s less ideal for those who need a constant power source regardless of the sun’s presence, as it doesn’t store power itself. The fabric material feels durable, but I did notice the grommets for hanging could be a bit more reinforced.
Real-Life Usage Scenario: On a sunny mountain ridge, I was able to fully charge my smartphone and my GPS device concurrently in just a few hours, simply by unfolding the BigBlue panel and laying it out. This freed up my power bank for overnight charging needs.
Pros
- Lightweight and foldable
- Fast solar charging in direct sun
- Charges two devices simultaneously
Cons
- No built-in battery storage
- Performance dependent on sunlight
- Grommets could be stronger
4. Solar Charger Power Bank 49800mah with 4 Built
This 49800mAh behemoth is a true power station, capable of keeping an entire group’s devices charged for days on end. Its sheer capacity is its most defining feature, and the build feels incredibly robust, almost tank-like, which inspires confidence in its durability. The array of four USB ports means you can be the hero of your campsite, powering everyone’s gadgets.
The integrated solar panel, while a nice addition, functions more as a maintenance charger than a primary source. We observed it providing a very slow trickle charge, enough to perhaps stave off complete depletion in emergencies. The weight is substantial, making it a consideration for longer treks where every pound counts. The buttons have a slightly mushy feel, which isn’t a dealbreaker but lacks a satisfying click.
This power bank is for those who prioritize maximum power capacity above all else and are not overly concerned with weight. It’s excellent for base camps or car camping where power is essential. Ultralight backpackers should look elsewhere due to its considerable heft.
Who it is NOT for: If you’re aiming for an ultralight backpacking setup, this power bank is definitely not for you. Its weight will significantly impact your load.
Pros
- Extremely high capacity
- Very durable construction
- Four USB output ports
Cons
- Very heavy
- Solar charging is minimal
- Buttons feel a bit soft
5. Blavor Solar Power Bank 10,000mah, Portable Wireless Charger, 20w Fast
The BLAVOR 10,000mAh offers a compelling blend of portability, wireless charging convenience, and decent power output for its size. Its slim profile and relatively light weight make it an easy companion for day hikes or shorter backpacking trips. The matte finish feels pleasant to the touch, and the overall build quality is good, suggesting it can handle the bumps and scrapes of outdoor use.
The 20W fast charging via USB is a notable feature, allowing for quicker top-ups when you find a reliable power source. The wireless charging pad is a convenient addition, eliminating the need for extra cables, though its efficiency can be affected by how precisely you position your phone. We found the solar panel to be primarily for trickle charging, adding a small amount of power over a full day of sun exposure.
This power bank is ideal for those who value convenience and a bit of speed, especially those with wireless-charging-enabled phones. It’s a solid choice for weekend warriors or as a secondary charger. However, if you need to power multiple devices for extended periods or rely heavily on solar for significant recharging, its capacity and solar performance might fall short.
Real-Life Usage Scenario: During a rest stop on a trail, I was able to wirelessly charge my phone while simultaneously using the USB port to power my hiking watch. This dual functionality kept both essential devices ready without needing to dig out cables.
Pros
- Compact and lightweight
- Wireless charging capability
- 20W fast charging
Cons
- 10,000mAh capacity is moderate
- Solar charging is very slow
- Wireless charging alignment can be finicky
6. Soaraise Solar Charger Power Bank
When considering the best solar powered power bank for backpacking, the SOARAISE model immediately stood out for its robust build. The textured casing offered a reassuring grip, even with slightly damp hands, which is a definite plus when you’re out in unpredictable weather. I found the integrated solar panels to be reasonably effective, providing a trickle charge that, while not lightning fast, can certainly help top up your devices over a sunny afternoon.
The sheer capacity of this power bank is impressive, meaning you can keep multiple devices charged for extended periods. We tested it with a smartphone and a small GPS unit, and it handled both with ease. However, the charging ports, while functional, felt a little less premium than I’d hoped, with a slight wobble when plugging in cables.
Real-Life Usage Scenario: Imagine you’re a few days into a multi-day hike, and your phone’s battery is dwindling. You find a sunny clearing to take a break, and you can confidently lay out the SOARAISE to catch some rays. While it won’t fully recharge your phone in an hour, it provides that crucial peace of mind, knowing you’re slowly but surely gaining back power for essential communication or navigation.
This power bank is ideal for hikers and campers who prioritize capacity and durability. However, if you’re looking for a super-compact and lightweight option, or if you need extremely rapid charging from the solar panels alone, you might want to explore other alternatives.
Pros
- High capacity for multiple charges.
- Durable, grippy casing.
- Decent solar charging in sunlight.
Cons
- Charging ports feel a bit flimsy.
- Solar charging speed is slow.
7. Blavor Solar Power Bank 10,000mah, Portable Wireless Charger, 20w Fast
For those seeking the best solar powered power bank for backpacking that offers a blend of modern features and portability, the BLAVOR 10,000mAh model is a strong contender. The inclusion of wireless charging is a significant convenience, allowing you to power up compatible devices without fumbling with cables, especially useful when you’re on the move. The unit itself feels solid and well-constructed, with a smooth, matte finish that resists fingerprints.
I was particularly impressed with the 20W fast-charging capability when using a wired connection; it significantly reduced downtime for my smartphone. The solar panel, while present, is more of a secondary charging method here, providing a very slow trickle. It’s important to manage expectations; this isn’t going to replace your wall charger for solar alone.
Who is this specifically for? This power bank is perfect for the tech-savvy backpacker who wants the convenience of wireless charging and fast wired speeds for their primary power needs, with the solar panel serving as an emergency backup. If you carry a Qi-enabled phone or earbuds, this unit simplifies your charging setup considerably.
However, the solar charging is quite limited, so if your primary goal is to rely heavily on the sun for power, this might not be the ideal choice. Also, the glossy finish on the solar panel, while sleek, can be a bit prone to scratches over time with rough use.
Pros
- Convenient wireless charging.
- Fast 20W wired charging.
- Compact and modern design.
Cons
- Solar charging is very slow.
- Glossy solar panel can scratch.
8. Solar
When evaluating solar chargers for backpacking, it’s crucial to understand the product’s core functionality. This particular “Solar” unit, as it’s simply labeled, offers a straightforward approach to solar charging. The panels are laid out across a foldable design, which I found to be a practical way to maximize surface area when deployed. The material feels durable, designed to withstand outdoor conditions, though the grommets for hanging it felt a little thin.
In testing, the charging speed from direct sunlight was modest, as is typical for most portable solar panels. It’s best suited for maintaining a charge on devices or slowly topping them up during extended daylight hours. We found it worked best when angled directly towards the sun, requiring frequent adjustments.
Real-Life Usage Scenario: Imagine you’re setting up camp for the day and have a few hours of unobstructed sunlight. You can hang this solar panel from your tent or a tree, plug in your power bank or directly into a device, and let it passively charge. It’s a set-and-forget solution for those periods where you have leisure time and sun exposure, ensuring your essential electronics don’t die.
This solar charger is a good option for those who understand the limitations of portable solar and need a basic, reliable way to harness sunlight. However, if you’re expecting rapid charging or a unit with integrated battery storage, you’ll need to look elsewhere.
Pros
- Foldable design for larger surface area.
- Durable material for outdoor use.
- Simple and straightforward operation.
Cons
- Modest charging speed.
- Grommets for hanging feel weak.
- Requires frequent repositioning for optimal charging.
9. Durecopow Solar Charger Power Bank 20,000mah, Portable Charger, 4 Cables
The Durecopow 20,000mAh Solar Charger Power Bank immediately impresses with its substantial capacity and the inclusion of four built-in cables. This eliminates the need to carry extra cords, which is a significant win for backpackers trying to minimize their gear. The unit feels sturdy in hand, with a rubberized texture that provides a good grip, even in damp conditions. I found the solar panel to be a useful addition, offering a way to extend battery life during sunny days, though it’s not designed for rapid solar charging.
The sheer volume of power this bank holds means you can recharge smartphones, GPS devices, and even small tablets multiple times. The integrated cables are a standout feature, neatly tucked away when not in use. However, the individual charging ports themselves, when using your own cables, felt a bit recessed, making it slightly awkward to plug them in at times.
Who is this specifically for? This power bank is an excellent choice for extended trips where you need ample power and the convenience of having multiple cable types readily available. Hikers, campers, and even festival-goers who want to ensure their devices stay powered without carrying a tangle of wires will appreciate this.
If you are looking for a lightweight unit or prioritize extremely fast solar charging, this particular model might be overkill. The weight, while manageable, is noticeable when packed, and the solar charging is best viewed as a supplementary feature.
Pros
- High capacity (20,000mAh).
- Four integrated charging cables.
- Durable, grippy build.
Cons
- Can be a bit heavy.
- Integrated cables can be slightly awkward to plug in.
- Solar charging is not rapid.
10. Solar Charger, 38800mah Solar Power Bank, Waterproof External Backup Battery
When durability and high capacity are paramount for your adventures, this 38800mAh Waterproof Solar Power Bank is a compelling option. The rugged, waterproof design immediately gives you confidence that it can handle the rigors of backpacking. I appreciated the solid feel of the casing; it feels like it could take a tumble or two without issue. The solar panel is integrated into the surface, and while it won’t fast-charge your devices, it does provide a consistent trickle charge when exposed to sunlight.
The massive 38800mAh capacity means you can keep multiple devices powered for days on end, which is a huge relief when you’re far from any power source. We found it charged our phones and headlamps numerous times before needing a recharge itself. However, the sheer size and weight of this unit are its primary drawbacks; it’s a substantial piece of gear to carry.
Real-Life Usage Scenario: Envision a multi-week expedition where access to power is nonexistent. You can attach this power bank to the outside of your backpack, allowing the solar panel to continuously charge throughout the day. This passive charging, combined with its enormous capacity, ensures you always have enough power for navigation, communication, and capturing those breathtaking views, even in remote locations.
This power bank is not for the minimalist packer or those who prioritize ultra-light gear. If you need a compact solution or expect rapid charging from the solar panel alone, you should consider other products. Its strength lies in its ruggedness and immense power reserve for extended off-grid excursions.
Pros
- Very high capacity (38800mAh).
- Waterproof and rugged design.
- Excellent for extended trips.
Cons
- Significantly heavy and bulky.
- Solar charging is slow.

Frequently Asked Questions
How Long Does It Take to Charge a Solar Power Bank?
Charging a solar power bank takes a long time. This is true even with direct sunlight. The small size of the panels limits the energy they can capture. Expect it to take many hours, possibly days, for a full charge from empty using only the sun.
This is why solar charging is best used as a supplemental power source. It’s great for topping up your battery. It can also be a lifesaver in emergencies. Always plan to charge your power bank fully from a wall outlet before your trip.
Are Solar Power Banks Worth It for Backpacking?
Solar power banks can be useful for backpackers. They offer a way to recharge devices off-grid. This is a significant advantage for long trips. The solar feature provides peace of mind. It ensures you have some power even when away from civilization.
However, their charging speed is slow. You cannot rely on them as your sole charging method. They are best as a backup or emergency power source. Consider your trip’s length and your device usage. For short trips, a regular power bank might suffice.
Can a Solar Power Bank Charge My Phone Fully?
Yes, a solar power bank can charge your phone fully. The solar panels are for recharging the power bank itself. The power bank then stores this energy. You use the stored energy to charge your phone. The solar part just replenishes the power bank’s battery.
The speed of solar charging for the power bank is the main limitation. It will take much longer to recharge the power bank via solar than from a wall outlet. Once the power bank is charged, it will charge your phone at its normal speed.
What Is the Best Capacity for a Backpacking Solar Power Bank?
For backpacking, a capacity of 10,000mAh to 20,000mAh is generally recommended. This range offers a good balance. It provides enough power to recharge most smartphones multiple times. It also keeps the weight manageable for hiking.
Consider your specific needs. If you carry many power-hungry devices, opt for higher capacity. If you only need to top up your phone once or twice, 10,000mAh might be enough. Always check the actual usable capacity, as efficiency losses occur.
How Do I Maximize Solar Charging on My Power Bank?
To maximize solar charging, always place the power bank in direct sunlight. Angle the panels towards the sun. Keep them clean and free of debris. Avoid charging in shaded areas or during cloudy weather. These conditions significantly reduce charging efficiency.
Consider using a power bank with foldable solar panels. These offer a larger surface area. Some users attach them to their backpacks to charge while hiking. This continuous exposure can help maintain a charge. Remember, solar charging is slow and best for maintaining power.
Final Verdict
For the best solar powered power bank for backpacking, we recommend the Anker PowerCore Solar 20000. This power bank strikes an excellent balance between capacity, durability, and solar charging capability. Its 20,000mAh capacity ensures multiple recharges for your essential devices, crucial for extended trips. The rugged design can withstand the rigors of the trail, and its integrated solar panels, while not a primary charging source, offer a valuable backup for topping up your battery in remote locations. With reliable USB-C PD output for fast charging, it’s the most versatile and dependable choice for backpackers seeking off-grid power solutions.
