Using the BioLite Solar Panel 100 is easy. First, find a sunny spot for your off - grid activities. Use the integrated sundial and kickstand of the Optimal Sun System to set up the panel so it catches direct sunlight. Once it's in place, you can directly connect your devices to the USB - A or USB - C PD ports to start charging. If you want a more powerful setup, pair it with the BioLite BaseCharge. When it comes to storage, fold the panel down to its compact size of 50.8 x 36.3 x 3.8 cm and use the storage pouch for added protection. Remember to keep the panel away from sharp objects to avoid damage. To clean it, simply use a soft, damp cloth. In case of rain, don't worry too much as the panel is water - resistant, but it's still a good idea to dry it thoroughly to ensure long - term performance. Also, when using the chaining adapter cable for a higher - wattage setup, make sure all connections are secure.
