Panasonic and a few other models do have versions that will use the phone in the base cradle to power the cradle so the other cordless units will function for a few hours, depending on use.
My Panasonic has a set of rechargeable batteries in the base station that will keep it alive for about 90 minutes. If the power is out for longer than that you can replace them with standard alkaline batteries for another 90 minutes.
