With a peak output of 1,250 watts, Goal Zero's Yeti 1250 is powerful enough for large-scale applicances. And unlike traditional diesel generators, there's no loud sound or stinky exhaust. Perfect for off-the-grid travels into the bush, or for power blackouts at home. The Yeti collects a full power charge in 20-22 hours with the two included Boulder 30 solar panels, or 16-20 hours with AC power. LCD indicators allow you to keep and eye on the 1250 watt-hour battery level. Three DC ports, three USB ports, and three AC ports give you multiple plug-in options for devices.
