The SunJack solar charger (via Treehugger) is a power source that’s both eco friendly and practical. Outlets don’t grow on trees, after all.
Billed as the “world’s most portable and powerful solar charger,” the SunJack comes in 14-watt and 20W versions, and features removable lithium-ion batteries that can actually recharge devices while being recharged themselves.
The 14W version comes with a single battery that takes about 5 hours to charge, while the 20W version comes with two.
The solar panels are sewn into a foldable carrying case and feature high-efficiency mono-crystalline cells. The larger of the two weighs around 2.7 pounds and measures 8.5″ x 12″ x 1.75″.
Creator Harold Tan was launched a Kickstarter campaign to fund production of the device, with a goal of $33,000. Tan has also linked sales to efforts to provide environmentally-safe lighting to villages in Papua New Guinea.
Campaign backers can choose to donate a SunJack or LED lightbulb to villagers, or purchase a charger for themselves at a discount ($169, versus the retail price of $250).
