Back Up Your Refrigerator And Cut Electricity Costs with BLUETTI FridgePower

A battery system called the BLUETTI FridgePower is designed to keep your refrigerator running during a power outage, protecting food and medicine when the grid goes down. It typically costs around $900, though promotions may lower that, and the maker offers a discount code (CLEANTECH) at checkout worth checking.

Beyond backup power, the device has a feature that can lower your electricity bill if your utility uses "time of use" pricing, meaning the cost per kilowatt-hour changes depending on the time of day. In the settings, you can switch the battery from "Standard UPS" mode to "Time Control UPS," then set specific "off-peak" hours for the battery to charge itself from the grid and "peak" hours when it should stop drawing grid power and instead run your fridge or other plugged-in devices from its stored charge. One reviewer's utility charged as little as $0.07 per kilowatt-hour overnight and as much as $0.23 per kilowatt-hour during peak afternoon or morning hours, so charging the battery during the cheap window and using it during the expensive window meaningfully cuts costs.

Not every utility offers time-of-use rates, and the pricing structure varies widely by location, so it's worth checking your own utility's rate schedule to see if this kind of shifting would actually save you money before assuming it applies to your home.
