I am wondering if this is a U P S (uninterruptable power supply)? Basically it is a power strip with a built in battery. When you have it plugged in it keeps the battery charged so if the power goes out you have a few minutes to shut everything down "properly". It also helps with a power flash (where the power flashes and does not go out). You can get different sizes based on what type of things you have plugged in to it. They are very nice and not terribly expensive.
same here I have not heard of this generator but all my machines are hooked up with a surge protector. Something I will have to look into this generator thing. Thanks for the info. ~hugs~
Thanks Karen for this. My machines are on a surge protector but I have never heard of using a generator before. All good advice for anyone who has a embroidery machine(s)
