Hey all, I am going on a trip to a cabin, and want to bring my Tablet. It has all my books on it. The cabin is powered with a propane generator. I know that there are voltage fluctuations, because there is a volt meter and it hangs around 120 but sometimes dips and moves about. Is it safe to plug my Acer into the wall socket, that is powered by this propane generator which has voltage fluctuations?
