Initial Setup & Charging

First-time setup for optimal solar charging.

  1. Unfold the solar panel completely on a flat surface.
  2. Position in direct sunlight, using kickstand for best angle (facing the sun).
  3. Connect your device to the USB port using your own cable.
  4. The LED indicator will light up showing charging status.
  5. For first use, charge the internal battery (if equipped) fully via solar or USB input.

IMPORTANT: For best results, ensure panels are clean and in direct, unobstructed sunlight.

Specifications

Controls and Indicators

Simple interface with LED indicator for status monitoring.

LED Indicator Behavior:

Physical Controls: None - automatic operation when device is connected and sun is present.

Charging Your Devices

Connect and charge smartphones, tablets, and other USB devices.

  1. Ensure solar panel is unfolded and positioned in direct sunlight.
  2. Use your device's original USB cable (or high-quality equivalent).
  3. Plug the USB end into either USB port on the solar panel.
  4. Connect the other end to your device.
  5. The LED will indicate charging status.
  6. Devices charge best when not in use during solar charging.

Tip: For faster charging, angle the panel perpendicular to the sun's rays and avoid shadows.

Solar Panel Operation

Optimal use for maximum power generation.

  1. Sunlight Requirements: Direct sunlight produces best results. Cloudy conditions reduce output.
  2. Positioning: Use kickstand to tilt panel toward the sun. Adjust every few hours as sun moves.
  3. Temperature: Extreme heat can reduce efficiency. Allow ventilation behind panels.
  4. Shading: Even partial shading on one cell can significantly reduce total output.
  5. Charging Time: Varies based on sunlight intensity, device battery size, and panel wattage.
  6. Storage: Fold neatly and store in dry, cool place when not in use.

WARNING! Do not stare directly at the sun when positioning panels. Do not expose to extreme heat sources.

Accessibility Features

Simple, intuitive design for all users. Tactile indicators on USB ports. Universal device compatibility.

Care & Maintenance

Proper care extends product life.

  1. Cleaning: Wipe solar panels with soft, damp cloth. Dry completely. Do not use abrasive cleaners.
  2. Storage: Fold neatly, store in cool, dry place away from direct sunlight when not in use.
  3. Water Resistance: While IPX4 rated, avoid submerging or exposing to heavy rain for extended periods.
  4. Cable Care: Disconnect cables by pulling on the connector, not the cable.
  5. Inspection: Periodically check for damage to panels, fabric, or connectors.

CAUTION! Do not attempt to disassemble or repair. No user-serviceable parts inside.
