Bought this plus the extension cable to add to my portable power station. I have regular power outages, one of which recently caused my fridge/freezer to be off for several days while I was away. With this new battery added, the fridge will stay powered when the grid goes down & there's enough energy for approx 6 days. The price was excellent value, free & fast delivery, & the packaging was really solid. I travel frequently so am already considering getting another one to connect my internet, security system, & other devices to ensure I can remotely monitor & keep my whole house powered during cyclone season.
