The Goal Zero Yeti 1250 is powerful enough to back-up critical appliances - refrigerators and freezers - as well as home health care equipment - heart monitors, oxygen & CPAP machines.Charge your Goal Zero Yeti 1250 in silence using the free and clean energy of the sun. You can also charge it from the wall. Either way, there are no worries of toxic fumes or the transportation and storage of flammable fuel.Multiple ports -DC, USB, and AC - make it easy to power all your devices. Activate the ports with one master switch and let everyone in the family help themselves.Because power is generated silently and cleanly from the sun or the wall, you can operate your Goal Zero Yeti inside the house, cabin, or tent. Our cart makes it easy to move the generator closer to appliances and use shorter extension cords, minimizing power loss and tripping hazards.What's in the Box: 1 x Goal Zero Yeti 1250 Solar Generator 1 x Roll CartTechnical Specs:USAGE Charges the following: Approx.
