Application Environment
Backup power for hiking, mountaineering, tourism, camping, outdoor activities, and field operations.
FAA-compliant for air/rail/maritime transport (≤160Wh lithium capacity per IATA PI 965 Section II).
Principles of Solar Power Generation
Solar Panels (SOLARPANEL) convert solar radiation energy into electrical energy by absorbing sunlight, either directly through the photovoltaic effect or indirectly through photochemical effects.
FAQ
What devices can this solar panel charge?
This panel supports USB-A, Type-C, and DC output. It can charge smartphones, tablets, power banks, flashlights, action cameras, and other small USB-compatible devices.
Is the battery inside the pack replaceable?
Yes. The integrated 5000mAh lithium battery is removable and can be replaced with another battery of the same specifications.
Does it support pass-through charging?
Yes. The solar panel can charge the battery pack while simultaneously powering external devices through the output ports.
What is the maximum output power of the solar panel?
Under optimal sunlight, the panel can deliver up to 40W of power, with a total output current of up to 10A. Actual performance depends on sunlight conditions.
Can I use the product at night?
Yes. The built-in battery pack stores solar energy collected during the day and can power your devices at night or during cloudy conditions.
Is the solar panel waterproof?
The panel is splash-resistant and suitable for outdoor use, but it should not be exposed to heavy rain or submerged in water.
