Power Up Anywhere with the ETFE Foldable Solar Panel

Whether you're camping deep in the wilderness, hiking remote trails, or simply traveling off-grid, the ETFE Monocrystalline Foldable Solar Panel keeps your devices charged using clean, renewable solar energy. Available in 30W (3-fold) and 40W (4-fold) configurations, this high-efficiency panel is engineered for adventurers who demand reliable power wherever the sun shines. Made in Mainland China.

Why Choose This Solar Panel?

  • High-Efficiency Monocrystalline Silicon Cells: Achieves a 16.5% photoelectric conversion rate, delivering more power from every ray of sunlight compared to standard polycrystalline panels.
  • ETFE Surface Coating: The premium Ethylene Tetrafluoroethylene (ETFE) laminate provides excellent durability, UV resistance, and weatherproofing — built to withstand the elements on every adventure.
  • Foldable & Ultra-Portable Design: Folds down compactly for easy storage in a backpack or travel bag. Unfold it and you're ready to harvest solar energy in seconds.
  • Fast & Efficient Charging: When sunlight is sufficient, the working current reaches up to 1.3A, charging your devices quickly and efficiently.
  • Strong Performance in Low Light: Unlike standard panels, this solar charger can still supply power during overcast or low-light conditions, keeping you connected even on cloudy days.
  • Wide Compatibility (5V / 9V / 12V Output): Compatible with most digital devices on the market — smartphones, tablets, cameras, laptops, and more.
  • Half-Moon Hanging Hole + Mountaineering Buckle: Easily attach to tents, backpacks, or other outdoor gear using the included carabiner-style buckle for hands-free charging on the go.
  • No Built-In Lithium Battery: Completely safe for air travel. No internal battery means no risk from high-temperature exposure and no airline restrictions — just pure photovoltaic power generation.
  • Eco-Friendly & Energy-Saving: Harness the sun's energy for safe, environmentally responsible charging anywhere you go.

Frequently Asked Questions

Q: Can I take this foldable solar panel on an airplane?

A: Yes! This solar panel has no built-in lithium battery, which means it is safe for air travel and complies with most airline carry-on regulations for electronic devices. It generates power purely through photovoltaic cells — no stored charge, no restrictions.

Q: What devices can I charge with this ETFE solar panel?

A: The panel supports output voltages of 5V, 9V, and 12V, making it broadly compatible with smartphones, tablets, cameras, laptops, and a wide range of other digital devices that accept USB or DC charging inputs.

Q: What is the difference between the 30W and 40W models?

A: The 30W model uses 3 foldable panels and is ideal for charging smaller devices like phones and cameras. The 40W model uses 4 panels, providing greater output power for faster charging or powering larger devices such as tablets and laptops.

Q: Does it work on cloudy days or in low-light conditions?

A: Yes. Thanks to its high-efficiency monocrystalline silicon cells, this solar charger is designed to perform even in weak or diffused light conditions, such as overcast skies — though output will be lower than in direct, full sunlight.

Q: How do I attach the panel while outdoors?

A: The panel features a half-moon hanging hole and comes with a mountaineering buckle (carabiner), allowing you to easily clip it onto a backpack, tent, or other outdoor gear for convenient, hands-free solar charging while you're on the move.
