SunJack Portable Solar Charger
For eons man has sought to harness the power of the sun… or at least since 1839 when Alexandre Edmond Becquerel observed the photovoltaic effect. GigaWatt has built on 175 years of research since then, and the culmination of that research is the SunJack Portable Solar Charger. This lightweight, durable, and compact (about the size of an iPad when folded) solar charger uses 14 Watts of high efficiency mono-crystaline solar cells in conjunction with a 8,000mAh lithium-polymer battery to keep you up and running wherever the sun shines. Powerful enough to charge its internal battery in just 5 hours or directly power a multitude of USB devices, SunJack is perfect for hikers, campers, or for any emergency bag. And when the sun goes down, the battery holds enough juice to fully fuel up to 4 smartphones at wall outlet charging speeds.
