The Yeti 1000X Solar Kit With Boulder 100 Briefcase combines Goal Zero's most versatile power station with a solar panel to charge it whether you're camping, fishing, hunting, or using it in the backyard. The 1000 wattage battery boasts enough power to charge phones or laptops in large groups, photography equipment, or GPS electronics when you're in the middle of nowhere. A 1500W AC inverter ensures enough juice for power-hungry devices and electronics. Goal Zero upgraded the 1000X with a USB-C port for faster charging, and the integrated MPPT enhances charge time from the Boulder 100 Briefcase.
