S35 Portable Solar Panel | 35W, USB-A & Type-C

The GEYOTO S35 is a lightweight, foldable 35W solar panel designed for directly charging phones, tablets, power banks, cameras, GPS devices, and other USB-powered electronics. It is ideal for camping, hiking, travel, emergency preparedness, and everyday outdoor use.

35W is the panel’s rated maximum output under standard laboratory conditions. Actual output depends on sunlight intensity, panel angle, temperature, cloud cover, shading, surface cleanliness, and the power accepted by the connected devices.

The S35 features two output ports:

One USB-C port supporting PD 3.0 charging up to 20WOne USB-A port supporting QC 3.0 charging up to 18W

Under suitable sunlight, the two ports can charge compatible devices simultaneously, with up to 35W of total available solar power.

Yes, but output will be significantly lower and may fluctuate as sunlight changes. For more stable charging, connect a power bank to the panel first and then use the power bank to charge sensitive electronic devices.

Passing clouds, shade, an incorrect panel angle, or insufficient sunlight can cause the output to drop. Some devices may automatically stop charging when the available power becomes too low. Reposition the panel in stronger sunlight and reconnect the device if necessary.

The solar panel surface is rated IP68 for water and dust resistance. However, the junction box, USB ports, and cable connections are not covered by this rating and must be kept dry. Always dry the panel completely before folding and storing it.
