RECOMMENDED YETI PAIRINGS

Solar charge times vary and are dependent on many factors such as elevation, temperature, time of year, angle and position to the sun.

Tips & Tricks for using solar panels

  1. The solar panel does not hold a charge - it only produces power when it is exposed to sunlight and connected to a power station or bank.
  2. Optimize solar panel efficiency by positioning them south-facing at a 45-degree angle.
  3. For faster recharging, use multiple solar panels.

I use the Boulder 100 Briefcase with a Yeti 500X and it does exactly what it promises. The two 50-Watt panels fold on a hinge, and the tempered glass plus aluminum frame with corner protection feels sturdy without being impossible to carry. The included canvas bag makes transport easy. Charge times match the listed range depending on sun and angle, so I just face it south at about 45 degrees. Remember it only produces power in sunlight, it doesn't store any. Solid, practical panel for camping and backup.
