Camping and hiking

Keeping a phone or tablet charged on a trip

What to expect from the sun

On a clear day with about four hours of strong sunlight, a 20W panel typically yields roughly 60Wh of usable energy after real-world losses. Cloud, haze, shade and a poor angle will reduce that.

Good to know

A solar panel only produces power while it is in sunlight, and its rated wattage is what it can deliver under ideal conditions, so real-world output will usually be lower. Angle the panel toward the sun and keep it free of shade. Before you order, make sure the panel's connector and voltage are compatible with the power station or battery you plan to charge.

Who this is not for

Anyone who needs to charge a laptop, a power station or high-wattage devices.

Setup and care

Unfold on a flat, stable surface angled toward the sun
Keep the panel clean and free of shade
Connect to a compatible device or controller before leaving it in the sun
Fold and store dry after use

Frequently asked questions

Does it work on cloudy days?
Yes, but charging will be much slower. Direct sunlight gives the best results.

Will it charge my device?
If your device charges over USB and the port listed in the specs matches your cable, yes. Charging speed depends on the sunlight and the device.

How should I store it?
Keep it dry, out of extreme heat and wipe it with a soft damp cloth. Fully charge any battery before long storage.

Look at something else if…

You need to charge a laptop or a power station
You need high-wattage charging

Rough estimates using typical device wattages. Real results vary with the device, temperature, sunlight and battery age.

Good to know about this one

Solar output drops when the angle is off. Reposition the panel toward the sun every hour or two for best results, rather than leaving it flat.

Plan before you need it

Solar works on the sun's schedule. Winter days are shorter and the sun sits lower, so panels produce less than in summer. If solar is part of your outage or off-grid plan, order the panels together with the battery or power station they will charge, and confirm the connector fits before the weather turns.
