  • FOOD PRESERVATION Prevent food from spoiling when stored inside a refrigerator. Food is among your most precious resources. Save as much of it as you possibly can!
  • ADAPTABILITY Adapt to different situations as your survival circumstances change. Use the generator as it charges from solar power during the day, then rely on stored energy at night.
  • LONG BATTERY LIFE ­– Since you can charge the generator while you use it, you’re less likely to deplete the battery. This extends the life of your battery for years and years of use!

The 2200XP battery provides protected charging options. Maximum Power Point Tracking, or MPPT, protects you and your electronics in an emergency through efficient charging.

This efficient charging refuels faster, ensuring your electronics operate fully sooner. Plus, the more efficient your energy use, the longer your electronics can run. Energy efficiency is optimal, reducing your dependence on unstable or unavailable power grids and making you more self-sufficient during disasters!

*The 2200XP Expansion Battery Unit contains only "DC-Out" ports. It will run devices (not included) with "cigarette lighter plugs" (12V adapters) or USB-A and USB-C plugs (like most cell phones). It can also run AC devices using an inverter adapter.
