this is a power station that offers the ability to operate as a whole-home backup solution, power an RV, power an off-grid domicile, charge a Tesla, or even run an industrial popcorn machine for hours on end
This unit operates as a UPS with a 10ms switchover time, which ensures no interruptions for critical appliances or lamps, just the same.
It does, however, weigh in at just over 113 pounds, so make sure that you either have help to move it around or that you're not going up and down stairs or loading it anywhere.
