A debate on r/prepping turned a humble kitchen appliance into a broader thought experiment about blackout cooking: Could a small rice cooker, powered by a battery pack and solar panels, quietly handle dinner when the grid is down and open flames feel too risky?
Here's what to know
On r/prepping, one user floated the idea that a compact rice cooker might fit into an outage plan. In a Reddit thread, they pointed to rice as a high-calorie staple and suggested cooking meat above it in a steamer tray, with the cooker running on stored solar power during a blackout.
The poster found the proposal appealing because of its modest power draw. They wrote that a rice cooker uses "only about 200 watts for 20-30 min of cooking time" and noted that much of the water stays inside rather than escaping as steam.
They also framed it as a lower-profile cooking method. As the poster put it, "the smoke from a fire would alert other people of your location and compromise your safety."
Not everyone agreed it was the most practical appliance. One commenter wrote, "Electric pressure cookers are even more energy efficient and can perform basically the same job plus loads of other cooking tasks."

The thread widened into a bigger comparison over which electric cooking device gives households the most flexibility when fuel is limited.

A commenter argued that a rice cooker is "very slightly more energy efficient for cooking rice, but it's not by that much," while adding that a pressure cooker can handle a much wider variety of meals.
The original poster, however, pointed to the power demands involved in that option. They said an Instant Pot could draw 700w and might need to be paired with "a 1000w power station," making it a much larger battery setup than the original 200-watt rice-cooker concept.
Commenters also listed other possible rice-cooker uses, including beans, and raised questions about soup, steaming vegetables, boiling water, and coffee. On the voltage side, the original poster said they were "not aware of any 12v pressure cookers available in the USA" and said they had learned that 12v rice cookers do exist.
If versatility is the priority, commenters kept circling back to pressure cookers. One commenter argued that "your best tool is the one that has many uses," while another recommended a portable induction burner, though others pushed back by saying induction cooking usually requires more watts and cannot handle tasks like soup on its own.
