Solar Panel
Solar Charger with Dual USB Ports, Waterproof & Portable Solar Panel for Outdoor Camping, Hiking, Emergency Devices
Important Notice:
Solar power output is influenced by actual geographical location and angle of sunlight. Panel power may not reach laboratory data.
Panels require sunlight to operate. Not just any light will suffice—sufficient sunlight is necessary.
Key Features:
✅Instant Setup & Go: Pre-attached carabiners and eyelets allow quick attachment to backpacks, tents, or gear—no tools required!
✅Wide Device Compatibility: Safely charges phones, power banks, LED lights, GPS devices, and other 3.6V-5V electronics.
✅Eco-Friendly Power Source: Harness renewable solar energy to reduce carbon footprint during outdoor adventures.
✅Built for Survival: Shock-resistant EVA layer protects against drops, dust, and extreme temperatures (-20°C to 60°C).
✅Smart Angle Optimization: Integrated tilt guidance (30-40°) ensures peak charging efficiency without manual calculations.

Frequently Asked Questions
1.Why does the solar panel charge intermittently?
A: Solar panels consist of numerous small photovoltaic cells connected in series and parallel. If the panel is partially shaded during use, it cannot form a complete circuit internally. This impairs the panel’s power generation efficiency and may even cause it to cease functioning.
The same principle applies to snow, dirt, dust, or grime—all of which can affect the panel’s performance.
2.Can it charge on cloudy or rainy days?
A: Power generation on cloudy days is approximately 10-20% of sunny days. We recommend pairing it with a power bank or storage battery. Output approaches zero during heavy rain.
3.Buyers report insufficient power after testing solar panel parameters with test equipment?
A: The buyer’s device plugs directly into the solar panel’s USB port. Since the USB port is regulated (typically 5V 2A), the maximum power measured via USB is theoretically only 10W. This testing method is inaccurate. Additionally, solar panel output power is affected by sunlight intensity, angle of incidence, and duration of exposure. Any obstruction on the panel surface will significantly reduce conversion efficiency and output.
4.Why did I not get 100w in the actual test of the 100w solar panel I purchased?
A: The maximum power of this solar panel is 100w, the maximum is obtained in the laboratory.Due to geographical constraints, most areas cannot get the maximum power of 100w.So how do you test the maximum power of a solar panel in your-self area?Wait for a sunny day, flatten the solar panels on the ground at 12 noon. Use a multimeter to test the metal sheets in the solar panel junction box.
