I have a UPS power backup unit here that I can't use. This is a Cyber Power model 1000PFCLCD. This should supply around 15 minutes of power to your computer & peripherals in the event of a power outage. Enough time to shutdown your delicate operations properly, save the doc you were just working on, or put your game on pause... Purchased several years ago (for around $109), I never used it in the old place because NONE of the circuits were grounded --so it wouldn't ever do anything. Now in the new place, nothing is grounded here either! Probably it works but I was never able to test it, since it requires a grounded circuit even to charge itself. It has not been abused except by a little dust. This is about the size of eight bricks all stacked together into a box shape... Probably heavier than eight bricks. Unscented; smoke- & cat-free. Will go with your other shiny black computer decor. Someone needs this! I want you to want this! Offering it here first, FREE to good home. I am still in Worcester, now on the quieter end of Vernon St. Pickup time flexible, and we have an off-street spot where you can temporarily park. Who wants this? Let me know. Liz J
