Comparison

User Tips / Usage Guide

  1. Placement: For best results, place the solar panel where it can access maximum sunlight—ideally on RV roofs or facing windows in a garage.
  2. Avoid Shading: Even though it performs well in partial shade, try to minimize shadows for optimal performance.
  3. Secure Properly: Utilize the suction cups on non-porous surfaces for a sure grip during windier conditions.
  4. Keep It Clean: Wipe down periodically to maintain its efficiency. Dust and debris can lessen its performance.
  5. Battery Type Caution: Always ensure compatibility with your device’s battery type. It's designed for 12V only.
  6. Seasonal Check: If used seasonally, store it in a dry, safe place during off-use months.
  7. Monitor Performance: Pair with a voltmeter occasionally to assess the charging efficiency.
  8. Consider Reflections: Maximize dual-sided absorption by placing near reflective surfaces when viable (e.g., metal or water).
