While portable power stations like the one you are describing are great, one needs to remember to plug the equipment directly into the generator to power up the equipment. Many utility workers are injured and even killed each year from people using home generators to supply power in emergency or even short power outages. Quite often people connect these devices directly into their homes electrical circuits in parallel with the outside power and when they are supplying power to the home with the generator; they are also feeding power up the lines to the main header. An electrical worker can come upon a line that is down, and should be dead. However, you may have inadvertently supplied power to the line and made it live. Ergo, dead electrical worker. Just something to think about. While I fully endorse the use of home generators, please make sure you have it wired into your home's electrical system by a licensed electrician.

Ok, down off soapbox
