Niveo NUPS22-1000U

So this has never been used, The fan makes to much noise for most residential purposes. Please be aware of loud fan noise before you decide to buy this. I believe this is more for a business internet power backup. The internal battery is not hooked up, you will need to connect it when you receive delivery.
