The 10 Best Portable Solar Charger for Backpacking Reviewed
1. Solar Charger Power Bank 49800mah Wireless Portable Phone Charger, 22.5w
We put this high-capacity power bank to the test on a recent weekend trip, and its sheer capacity is impressive for keeping multiple devices topped up. The wireless charging feature is a nice addition for convenience, especially when you don’t want to fumble with cables in the dark. Its robust build feels like it could withstand some rough handling in a backpack.
However, the sheer size and weight of this unit are notable drawbacks for ultralight backpackers. Charging it fully via solar alone would take an eternity, so relying on a pre-charge is essential. The plastic casing, while seemingly durable, has a slightly cheap feel to the buttons. It’s definitely a power horse, but not for those prioritizing minimal weight.
This power bank is ideal for car camping or longer trips where power outlets are scarce and you’re not concerned about adding a few extra ounces. It’s also great for families or groups sharing one charger. If you need to keep a tablet, headphones, and your phone alive for days, this might be your pick.
Pros
- Massive capacity for multiple charges.
- Wireless charging offers added convenience.
- Sturdy construction.
Cons
- Very heavy and bulky.
- Solar charging is extremely slow.
- Buttons feel a bit plasticky.
2. Solupup Solar Panels 30w Portable Foldable Solar Charger
During our testing, the SOLUPUP 30W panels proved to be a capable option for generating power on the go. Its foldable design makes it relatively compact for transport, and the included grommets make it easy to attach to a backpack or tent. We found it could provide a steady trickle charge to our devices on sunny days.
While it performs adequately in direct sunlight, its efficiency drops significantly under partial shade or overcast conditions, which is common in mountainous terrain. The fabric casing, while lightweight, feels a bit flimsy and I worry about its long-term durability against abrasions. It’s best suited for situations where you have consistent, strong sunlight for extended periods.
This charger is a good choice for day hikers or basecamp users who need a supplemental power source and have reliable sun exposure. It’s not designed for rapid charging, so patience is key. If you’re constantly moving through shaded forests, you might find its output too inconsistent.

- Fabric casing feels somewhat fragile.
- Not for rapid charging.
3. Soaraise Solar Charger Power Bank
We tested the SOARAISE Solar Charger Power Bank, and its integrated solar panel is a definite plus for off-grid situations. The build quality feels solid, and the rubberized exterior offers good grip and some protection against bumps. It’s positioned as a potential best portable solar charger for backpacking, and its all-in-one nature is appealing.
However, the solar charging speed on this unit is quite slow, even in optimal conditions. You’ll need to leave it in direct sun for a full day to see a significant charge. The LED indicator lights, while functional, are a bit too bright for use in a tent at night. It’s a good backup, but not a primary charging solution for heavy users.
This power bank is best for emergency situations or for those who only need to maintain a charge on their phone for basic communication. It’s a solid choice if you value having a solar option built-in, but don’t expect it to power multiple devices quickly.

- Not suitable for fast charging multiple devices.
4. Blavor Solar Power Bank 20000mah Built
Our experience with the BLAVOR 20000mAh Solar Power Bank revealed a decent capacity in a relatively compact package. The built-in solar panel offers a theoretical top-up, which is better than nothing when you’re out in the wild. The unit feels sturdy in hand, and the ports are well-protected by rubber flaps, which we appreciated in dusty conditions.
The primary drawback is the solar charging capability, which is more of a novelty than a practical charging solution. It took an entire day of direct sunlight to add just a few percentage points to our phone’s battery. The plastic casing, while not flimsy, doesn’t inspire confidence for extreme backcountry abuse. It’s a power bank first, solar charger second.
This power bank is suitable for casual campers or day-trippers who want a backup power source and don’t rely heavily on solar. If you’re looking for a primary solar charging solution, you should look elsewhere. Those who need a reliable power bank with a small solar bonus for emergencies will find it adequate.

- Ports are well-protected.
- Sturdy feel.
Cons
- Solar charging is extremely inefficient.
- Solar function is more of a gimmick.
- Casing might not withstand heavy abuse.
5. Bigblue 28w Solar Panel Charger with Dual USB
We found the BigBlue 28W panel to be a solid performer for its wattage, capable of charging two devices simultaneously in good sunlight. Its foldable design is practical, and the included carabiners make it easy to hang from a backpack. The fabric is a bit stiff, which provides a reassuring sense of durability. It’s a good option for generating power for a small group.
However, the charging speed is highly dependent on direct, unwavering sunlight, and we noticed a significant drop in output when even a small cloud passed over. The USB ports are exposed, and while there’s a small fabric flap, I’d be concerned about dust and moisture getting in over time. It’s not the most compact panel we’ve tested.
This solar panel is an excellent choice for car camping, base camps, or for hikers who have dedicated downtime in sunny locations. It’s not ideal for those constantly on the move through varied terrain. If you need to keep two phones or a phone and a tablet charged during a sunny day, this panel is a strong contender.
Pros
- Charges two devices simultaneously.
- Durable fabric construction.
- Includes carabiners for easy attachment.
Cons
- Performance highly dependent on direct sun.
- Exposed USB ports could be an issue for durability.
- Not the most compact option.
6. Blavor Solar Power Bank with Hand Crank and 4 Cables
I’ve been testing portable power solutions for backpacking for years, and the BLAVOR with its integrated hand crank immediately caught my eye. The ability to generate power in a true emergency, even without sunlight, is a significant advantage for extended trips. The built-in cables are a nice touch, reducing the need to carry extras, though I found the attached cable somewhat short for convenient use while charging.
The solar panel surface feels durable, and it did manage to trickle charge the battery during a sunny afternoon hike. However, as with most small solar panels, don’t expect this to be your primary charging method; it’s more of a top-up or emergency backup. The hand crank itself requires a fair bit of effort to generate a meaningful amount of charge, but it does work, providing a reassuring sense of self-sufficiency.
This power bank is best suited for the ultralight backpacker who prioritizes redundancy and preparedness above all else. If you’re venturing into remote areas where power outlets are non-existent for days on end, the hand crank offers peace of mind. However, if you’re primarily looking for fast charging and don’t anticipate extended periods without sun, you might find the hand crank feature a bit bulky.

- Hand crank for emergency power generation.
- Integrated cables reduce clutter.
- Durable build quality.
Cons
- Hand crank requires significant effort.
- Charging speed is slow, especially via solar.
- Integrated cable is a bit short.
7. Solar Charger Power Bank, Pd 20w Fast Charging External Battery
When considering the best portable solar charger for backpacking, speed and efficiency are paramount. This unit boasts PD 20W fast charging, which is a substantial improvement over many solar-focused chargers. I found that it could indeed top up my devices at a respectable pace when connected via USB-C. The solar panel itself is reasonably sized, and while it won’t fully recharge the battery quickly, it offers a welcome supplementary charge during daylight hours.
The build feels robust enough for trail use, with a textured grip that prevents accidental drops. However, the solar panel’s efficiency is still limited by its surface area, meaning you’ll still need prolonged sun exposure for any significant power gain. I noticed that the charging indicator lights could be a bit brighter for easier visibility in direct sunlight.
This power bank is ideal for backpackers who rely on their devices for navigation and communication and need quick top-ups. If you have limited time to charge during breaks or at a campsite with good sun exposure, the 20W PD is a real advantage. Those who expect the solar panel to be a primary charging source should temper their expectations; it’s a valuable backup, not a replacement for a wall charger.

- Robust build with good grip.
- Decent solar panel surface area.
Cons
- Solar charging speed is still moderate.
- Indicator lights could be brighter.
- Bulkier than non-solar power banks.
8. Blavor Solar Power Bank 10,000mah, Portable Wireless Charger, 20w Fast
For a backpacking trip, having multiple charging options is key, and this BLAVOR model offers both wired and wireless charging, alongside solar. The 10,000mAh capacity is a good balance for carrying weight and providing enough power for a few device charges. I appreciated the convenience of placing my phone on top for a wireless charge, although it does add a slight thickness to the unit. The 20W fast charging for wired connections is a definite plus.
The solar panel is integrated into the back, and while it does contribute to topping up the battery, its output is modest. I found it best for maintaining a charge rather than significantly replenishing it. The unit has a solid feel, but the plastic casing, while durable, doesn’t feel particularly premium. The placement of the ports is sensible, keeping them protected.
This power bank is a strong contender for the tech-savvy backpacker who values versatility and doesn’t want to carry multiple chargers and cables. If you have a Qi-compatible smartphone and want the option of wireless charging on the go, this is a convenient choice. However, if your priority is solely the fastest possible solar charging, you might find other dedicated solar panels more efficient, despite the added bulk.
Pros
- Wireless charging capability.
- 20W wired fast charging.
- 10,000mAh capacity offers good power.
Cons
- Solar charging is supplementary, not primary.
- Plastic casing feels functional but not high-end.

9. Soaraise Solar Charger Power Bank
The SOARAISE solar charger power bank presents a straightforward solution for keeping devices powered in the backcountry. Its design is fairly compact, making it easy to clip onto a backpack for passive charging while hiking. I found the solar panel surface to be fairly resistant to minor scuffs, which is important for outdoor gear. The unit includes multiple output ports, allowing for charging more than one device simultaneously.
When it comes to actual charging speed, the solar input is, as expected, quite slow. It’s best viewed as a way to slowly maintain battery levels or add a small percentage of charge over a full day of good sun. The power bank itself holds a decent charge, but recharging it fully from empty via solar would take an exceptionally long time. The buttons have a slightly mushy feel when pressed.
This power bank is well-suited for casual backpackers or day hikers who need a reliable backup power source for their phone or GPS. If you’re looking for something to keep your devices alive during multi-day treks without access to power, and you understand the limitations of solar charging, this is a solid option. However, if you need to rapidly charge devices or rely heavily on solar input for substantial power, you’ll likely be disappointed.
Pros
- Compact and easy to attach to a pack.
- Multiple output ports for simultaneous charging.
- Reasonably durable solar surface.
Cons
- Solar charging is very slow.
- Power bank takes a long time to recharge via solar.
- Buttons have a mushy feel.
10. Blavor Solar Power Bank 10,000mah, Portable Wireless Charger, 20w Fast
This second BLAVOR model I tested offers a compelling combination of features for the modern backpacker. The 10,000mAh capacity provides a good amount of juice, and the inclusion of both 20W wired fast charging and wireless charging options is a significant convenience. I particularly liked the flexibility of being able to just place my phone on the charger without fumbling for cables, especially when setting up camp in low light. The unit feels solid in the hand, though the glossy finish is a fingerprint magnet.
The solar panel, while present, serves more as a supplementary trickle charger. I found it useful for maintaining the power bank’s charge during a sunny day, but it’s not a realistic option for fully recharging it quickly. The speed of the 20W wired charging, however, is impressive and can quickly bring devices back to life. The LED indicator lights are bright and easy to see, even in daylight.
This power bank is an excellent choice for the gadget-oriented backpacker who wants convenience and multiple charging methods in one device. If you have a Qi-enabled phone and appreciate the speed of 20W charging, this BLAVOR offers great value. However, if your primary goal is to maximize solar energy capture for off-grid living, you might find that a dedicated, larger solar panel offers more efficient power generation, even if it means carrying an extra item.
Pros
- Fast 20W wired charging.
- Convenient wireless charging option.
- 10,000mAh capacity is ample.
Cons
- Solar charging is slow and supplementary.
- Glossy finish attracts fingerprints.
- Can be a bit bulky with wireless charging.

Frequently Asked Questions
How Much Wattage Do I Need for a Backpacking Solar Charger?
For most backpackers, a solar charger between 10W and 20W is a good starting point. This wattage is usually enough to charge a smartphone or a small GPS device effectively. If you plan to charge multiple devices or larger electronics like a tablet, you might consider a higher wattage charger, perhaps 25W or more.
It’s a balance between charging speed and the charger’s size and weight. Higher wattage often means a larger and heavier panel. Always check the charger’s specifications for its actual output under ideal sunlight conditions.
