1. BigBlue 28W Solar Panel Charger with Dual USB-C and USB-A Ports for Backpacking, Camping, and Hiking
This BigBlue 28W panel is a top-tier choice for serious backpackers who need reliable, fast power for multiple devices. Its advanced solar cells and smart port configuration deliver consistent performance even in imperfect conditions, making it a workhorse you can trust on any trail.
Key Features That Stand Out
✓ High 25.4% efficiency from shadow-free N-type solar cells.
✓ Triple-port design with dual USB-C and one USB-A for versatile charging.
✓ IP44 waterproof rating for protection against rain and splashes.
✓ Compact, foldable design with four kickstands for optimal sun angle.
Why We Recommend It
It strikes the perfect balance between power, portability, and ruggedness. The dual USB-C ports are a future-proof feature for modern devices, and the high efficiency means you get more juice from fewer hours of sunlight. For a multi-day trip where every ounce and watt counts, this panel is a reliable partner.
Best For
Backpackers and campers who need to charge two or more devices quickly, such as a phone and a power bank, and want a durable, high-performance panel that can handle variable weather.
Pros and Cons
Pros:
- Excellent power output for its size and weight.
- Versatile port selection covers most device types.
- Very good build quality with effective waterproofing.
- The shadow-free design minimizes power loss from partial shading.
Cons:
- Slightly heavier than some ultralight-specific panels.
- The kickstands, while useful, can be a bit fiddly to set up in wind.
Customer Reviews
Customer Review: “When I first purchased this portable solar panel, I was skeptical about its capabilities. To be honest, I didn’t anticipate its impressive performance.

Customer Review: “This solar charger works awesome! Took it to Death Valley for a two week long camping trip, never lost a charge in my phone, flashlight, camera, or any of my rechargeable equipment. The USB-C port charged our iPhones much faster than the USB-A port…”
2. BigBlue Portable 35W Solar Panel Charger with Fast Charging USB-A and PD 25W USB-C for Camping Ba…
For the tech-savvy backpacker with power-hungry devices, this BigBlue 35W panel is a powerhouse. Its PD 25W USB-C port can fast-charge modern phones and even some tablets at their maximum speed, significantly cutting down charging time when the sun is high.

4. BigBlue 25W Ultra-Light Solar Panel Charger with USB Ports, IP68 Waterproof, and 0.84 lbs Weight for Backpacking
Weighing in at a remarkable 0.84 lbs, this BigBlue panel is a dream for ultralight backpackers. It proves you don’t have to sacrifice all power to shave ounces, offering solid 25W output in a package that folds to the size of an iPad.

8. Goal Zero Nomad 10 10W Monocrystalline Foldable Solar Panel with USB Port and Adjustable Kickstand for Backpacking
From a pioneer in portable solar, the Goal Zero Nomad 10 is a simple, robust, and trusted panel. With a lower 10W output, it’s designed for trickle-charging a phone or keeping a small power bank topped up, prioritizing durability and reliability over raw speed.

Customer Review: “Good value for a waterproof panel. Charges my phone steadily. It’s not the absolute fastest, but for the price and the protection it offers, I’m very happy with it.”
10. BigBlue 28W Folding Solar Charger with Digital Ammeter, High-Efficiency USB Ports, and Waterproof Design for Backpacking

Complete Buying Guide for Best Solar Panels For Backpacking
Essential Factors We Consider
Choosing the right solar panel is more than just picking the highest wattage. You need to balance several key factors for your specific trip. Weight and Packed Size are paramount for backpacking; every ounce counts. Look for panels under 1.5 lbs if possible. Power Output (Wattage) determines charging speed. 10-15W is fine for trickle-charging a phone, but 20-30W is better for power banks and faster phone charging. Durability and Weather Resistance are critical. An IPX4 or higher rating protects against rain, while IP67 or IP68 offers near-total dust and water protection. Finally, consider Port Configuration: USB-C with Power Delivery (PD) is best for modern phones, while multiple ports let you charge more than one device at a time.
Budget Planning
Solar panels for backpacking range from budget-friendly to premium. You can find capable panels between $50 and $100 that offer great value, like our “Best Budget” pick. Mid-range models ($100-$150) often add better efficiency, faster charging tech, and improved durability. Premium panels ($150+) typically offer the best power-to-weight ratios, top-tier brand reliability, or specialized features like advanced shading tolerance. Remember, the best panel is the one you’ll actually carry and use—sometimes a lighter, simpler, cheaper panel is more valuable than a feature-rich one that stays at home.
Final Thoughts
Your perfect solar panel is the one that matches your trip style and power needs. An ultralight thru-hiker will choose differently than a car camper or a group backpacking in a base camp. Think about how many devices you need to power, how much sun you’ll realistically get, and what you’re willing to carry. The best solar panels for backpacking are those that become a seamless, reliable part of your kit, giving you the freedom to explore further without the anxiety of a dead battery.
Frequently Asked Questions
Q: Can a solar panel really charge my devices while I’m hiking?
A: Yes, but with a key strategy. It’s most effective to attach the panel to your backpack to soak up sun while you walk, charging a power bank in your bag. The power bank then charges your phone safely at night. Direct charging to a phone while hiking can be inconsistent due to movement and shading.
Q: How long does it take to charge a phone with a solar panel?
A: It varies widely. Under ideal, direct sun, a 20W panel might charge a modern phone from 0% to 50% in 1.5-2 hours. Cloud cover, panel angle, and the phone’s own charging limits can double or triple that time. Charging a large power bank can take a full day of good sun.
Q: Are solar panels worth it for a weekend backpacking trip?
A: For a typical 2-3 day trip, a large power bank (10,000-20,000mAh) is often simpler and more reliable. A solar panel becomes worth it for trips longer than 3-4 days, or if you’re using your phone heavily for GPS, photos, or satellite communication and need to replenish power daily.
Q: What does “IP” rating mean for solar panels?
A: IP (Ingress Protection) ratings indicate dust and water resistance. The first digit (0-6) is for solids/dust, the second (0-8) for liquids. For example, IP68 is dust-tight and can be immersed in water. For backpacking, look for at least IPX4 (splash-resistant) but IP65 or higher is better for serious weather.
Q: Do I need a special power bank for solar charging?
A> Not necessarily, but some are optimized for it. Look for a power bank with “solar input” or that accepts a wider range of input voltages. Many standard power banks will work fine, but may charge slower from a solar panel’s fluctuating output compared to a steady wall charger.
Stepping off the grid doesn’t mean disconnecting completely. With the right solar panel securely fastened to your pack, you can capture the sun’s energy all day long, ensuring your essential electronics stay powered for navigation, safety, and capturing those unforgettable trail moments. Whether you prioritize lightning-fast charging, ultralight minimalism, or unbeatable value, one of the panels on this list is ready for your next adventure. Assess your personal power needs, check the weather forecast, and make the choice that will keep you connected mile after mile. Ready to harness the sun?
