With its convenient briefcase design and weighing in at around 4.5 kg, these high quality monocrystalline panels pack up to 100W of solar generating power into a lightweight yet rugged package! Easy to carry with you on camping, boating and beach trips, the SP100 has a switchable 18/36V output which allows for charging of a wide range of battery types. Via the 18V output it efficiently charges our PS300 portable power supply, especially when there is some intermittency due to cloud cover. Via the included solar charge controller you can charge virtually any camping battery such as Goal Zero products and a wide range of lead acid, AGM and other sealed batteries. Experience the freedom and peace-of-mind of knowing that you can go anywhere your sense of adventure takes you while still enjoying the comforts of home like fridges, phones, tablets, cameras, lighting and much more. Happy travels!
