First off power inverters aren't cheep, but if you can use it for other things then it might be a good idea. The freezer will draw less than 100 watts when running, but it is the start up when the motor first kicks on that takes the max amount of power so make sure that you pick one with at least double your peak power requirement.

The freezer will work at its most optimum when it is kept full or nearly full. So pick the freezer you need to just cover the amount of meat you will be brings home with a small amount for excess (guessed too small). Of course if you can get the meat frozen before you put it into the freezer you will way better off and the freezer won’t have to work as hard.
