I saw this recently on a TV news feature as Dorian was approaching Florida. It is a silent battery power source with three 120V outlets and four USB ports.

I doubt that it could be attached directly into your home power. Its main uses - as described on the feature - were to power tools at a job site or as a camping power source.

Any experience / comments?
