I know nothing about generators. I do know that they are a good idea and would like to pick up a small one for emergency purposes while we live here in the city. Harbor Freight has a Chicago Electric generator on sale for $89.99 this weekend. The ad only states that it is 800 rated watts/900 max watts. I have absolutely no idea what that means. Would it do in a pinch to run the refrigerator and maybe a couple of appliances? Would it run the fridge and say, the computer and some lights or the microwave. I'd appreciate it if someone more knowledgeable could help me out with some wisdom. It would strictly be for short term use, a short term power outage, not a full time power supply for a SHTF scenario. Thanks.
