Best Portable Solar Panel for Camping in 2026
A portable solar panel keeps your devices charged on multi-day trips without access to power. A 20-25W panel charges a phone in 2-4 hours of direct sun, a GPS in 1-2 hours, or fills a battery bank over a full day of hiking. For weekend camping with a phone and headlamp to charge, a 20W panel is sufficient.
Wattage Guide
10W: Phone charging only, slow. Adequate for 1-2 day trips with one device.
20-25W: Phone + GPS + earbuds. Fills a 10,000 mAh battery bank in 6-8 hours of good sun. Best for most backpackers.
40-60W: Multiple devices + laptop. Car camping and basecamp use. Heavy for backpacking.
100W+: RV and van life. Requires charge controller. Not portable in the backpacking sense.
Top Picks
Best Backpacking: BigBlue 28W Solar Charger
Price: ~$60 | Best for: 28W, lightweight, foldable, USB-A + USB-C
BigBlue 28W folds to book size and weighs 20 oz. Three USB outputs (USB-A x2, USB-C) allow charging multiple devices simultaneously. SmartIC technology identifies each device and delivers optimal charging current. In practice, delivers 2-3A in good direct sun — sufficient for fast charging a phone in 2-3 hours.
At $60, the best value in foldable backpacking solar panels. Attach to the back of your pack with included carabiners and charge while hiking.
Pros: $60, 28W, 20 oz, USB-A + USB-C, fold flat, charge-while-hiking design
Cons: USB direct only (no battery bank — pairs with a power bank), no built-in storage
Best with Battery: Goal Zero Nomad 20 + Sherpa 100 Bundle
Price: ~$350 bundled | Best for: Integrated system, multiple devices, power bank included
Goal Zero Nomad 20 solar panel + Sherpa 100AC power bank bundle provides the complete off-grid power system: solar panel charges the power bank, power bank charges devices (including laptops via 100W AC outlet). Suitable for extended trips or photographers with camera battery needs.
The Nomad 20 panel alone (~$80) is also the best standalone foldable panel in its class — ETFE coating for durability, kickstand for optimal angle, weather-resistant.
Pros: Complete system, 100W AC output (laptops), Goal Zero ecosystem, durable build
Cons: $350 bundled cost, 2+ lb power bank adds pack weight, overkill for phone-only charging
Budget Pick: Anker PowerPort Solar Lite 15W
Price: ~$35 | Best for: Ultra-budget, phone charging only, USB-A
Anker's 15W folding panel delivers basic phone charging at $35. Two USB-A ports. PowerIQ delivers up to 2.4A total. 14.7 oz folded. For backpackers who only need to top off a phone every 2-3 days and do not want to spend $60+ on solar.
Pros: $35, 14.7 oz, Anker reliability, two USB-A ports
Cons: 15W (slow for anything beyond phones), USB-A only (no USB-C), 15W underperforms in partly cloudy conditions

Frequently Asked Questions
How much sun do I need for effective solar charging?
Direct, unobstructed sunlight produces rated wattage. Partial cloud cover reduces output 50-80%. Fully overcast reduces output 80-90%. A 28W panel in partly cloudy conditions may deliver 8-15W effective — enough for slow phone charging. Positioning the panel perpendicular to the sun maximizes output.
Can I charge a laptop with a portable solar panel?
Small panels (10-30W) do not deliver enough power for most laptops (45-65W requirement). A battery bank charged by solar (Goal Zero Sherpa 100AC) can then charge a laptop from stored energy. Direct laptop charging from a small panel is impractical.
Do I need a charge controller?
Foldable USB solar panels include built-in regulation — no separate charge controller needed. Charge controllers are required when connecting rigid panels directly to 12V battery systems (RV, van builds).
