28W Foldable Solar Panel with Dual USB Outputs

Product Overview

This 28W foldable solar panel provides a compact way to collect solar energy for compatible USB-powered devices during camping and outdoor trips. Four connected monocrystalline sections unfold into a long, narrow panel and pack down into a rectangular format for carrying between stops.

Dual USB outputs provide two connection points, while an ETFE front surface covers the solar cells. The dark fabric-backed construction and rear connection module keep the panel and its outputs together in one portable unit.

Key Features

• Four-panel folding layout: opens out for solar collection and reduces the footprint when packed.
• Dual USB outputs: provides two ports for compatible devices without a separate external output box.
• Monocrystalline cells: a compact solar collection area for a portable charging setup.
• ETFE front surface: covers the cell face while retaining the folding format.
• Integrated rear module: keeps the connection points on the panel assembly.

Outdoor Charging & Handling

Unfold all four sections and position the solar face toward direct sunlight. Keep the panel steady and avoid covering individual sections. Fold the panel for carrying rather than placing pressure on the cell surfaces.

Before connecting a phone, power bank or other device, check its input requirements and use a suitable USB cable. Keep electrical ports and connected electronics dry. Rated panel power is not a guaranteed USB charging rate: available output depends on sunlight, panel angle, temperature, connected-device limits and the charging setup.
