4 hours sure but not if your power is out for days on end.Why? Aren't electric chest freezers efficient enough on their own?
With all the LS it's always a gamble if your power comes back. I had a full freezer spoiled in Feb when the local transformer blew, and again in March when cables grew legs. Running genny at night only did not help.
Personally, I ended up buying a Kool inverter that can use solar to keep my freezer frosty.
