I have a 3000VA UPS Battery Backup for sale. This unit has a 30 amp twistlock on the end, but it could be changed for a normal plug. It does not have batteries with it, however you can buy them online for about $80. This unit is meant to be for enterprise and corporate environments. It is a rack unit and is very heavy. It is capable of powering giant loads and could easily run your business equipment or home computers for a long time.
I am asking $300 OBO. This unit new sold for well over $1,500.
