A power outage can threaten more than a household's food supply. It can also wipe out multiple shopping trips' worth of savings from discounted groceries and homemade meals stored in the freezer.
One U.K. prepper raised this concern on Reddit, asking whether keeping less food would help prevent waste. Fellow users reassured them that a full freezer could offer some protection during a blackout.
Here's what to know
Posting in Reddit's r/UKPreppers community, the original poster described buying reduced-price groceries, saving leftovers, and batch-preparing meals. Worried about losing food during an outage, they were considering cutting their supply to about a week's worth of raw meat and ready-to-heat meals.
"How are you guys balancing keeping a frugal stash in the freezer vs what might be wasted in a power cut?" the original poster asked.
One commenter suggested that picnic-box cold packs could fill any empty space. Several users advised keeping the freezer stocked because frozen contents help it stay cold longer without power.
Once thawed, frozen water bottles could double as drinking water, providing an added benefit of another suggestion from commenters.

The commenter who suggested cold packs reported experiencing just one three-day outage in 20 years, while acknowledging that interruptions could be more frequent elsewhere.
More background
Convenience also mattered to the original poster. Pizza and simple oven-ready food were available for days when cooking felt like too much work. The freezer also contained ice cream alongside the homemade meals.
During a prolonged outage, one respondent planned to eat through their homemade meals while avoiding unnecessary opening of the freezer drawers.
"Saving money, and the planet, over the long term is more important to me than potentially losing power long enough for my freezer to completely defrost, which is pretty unlikely to happen," they added.
One commenter said equipment that could meaningfully extend refrigeration cost more than the food in their freezer. Still, they owned a backup system they estimated could power their fridge and freezer for an additional day, partly to maintain access to refrigerated food.
What can be done?
Meals need not depend entirely on refrigeration if tins and packets are available, another commenter noted, recommending that households keep some on hand.
Another Redditor estimated that their home batteries could provide 48 hours of carefully limited electricity use. They also pointed to their car's 3.0-kilowatt vehicle-to-load feature as a potential way to power a freestanding freezer.
Neighbors could share food cooked on a barbecue, the same commenter suggested, noting they had a spare gas tank. The original poster welcomed that plan. Another Redditor described taking that approach during a five-day tornado-related outage in Canada, cooking meat on a barbecue and sharing it with neighbors.
"Something that might be worth thinking about is how your freezer is a financial prep," a commenter asserted. "Having a really good amount of frozen, home cooked meals in my freezer got me through a difficult redundancy period."
Where can I learn more?
Keeping freezer food safe during an outage may mean checking temperatures or having backup power ready.
• A homeowner seeking freezer power alerts received advice to monitor temperatures instead during outages.
• A Jackery Explorer 1000 owner said backup power saved $300 in groceries during an outage.
• A homeowner buying a backup battery learned their Sub-Zero refrigerator's plug might sit up top.
• An apartment renter used a Jackery battery for refrigeration while commenters recommended butane cooking.
