Forget Giant Batteries: Small Ones Are Hiding in Stoves and Food Carts

There's a traffic jam in American electricity. Big battery farms — the shipping-container-sized kind that store power for whole neighborhoods — are slow and expensive to build, especially in dense cities like New York, where permits and regulations can drag on for years. So a group of startups is trying a different trick: shrink the batteries and hide them inside things you already use.

PopWheels runs about 50 battery-swap cabinets across New York City, where delivery drivers on e-bikes trade empty batteries for fresh ones instead of waiting around to charge. It now also powers food carts, replacing the noisy gas generators they run on — roughly four of its batteries cover a full day of selling. Copper builds induction stoves with a battery inside, so you can cook when the power goes out, and you may skip a costly electrical panel upgrade. Every Electric sells a battery that plugs into a window air conditioner. David Energy does the same for laundromats, parking garages, and gyms, paying owners to cut power use when the grid is strained.

Why does this matter to you? Cheaper bills, cleaner air, and fewer blackout days in hot summers. Because these devices plug in like a lamp, they dodge the permits and wiring upgrades that stall big projects. Individually they're tiny. Added up, they're huge: if every stove in America shipped with a battery, that's tens of gigawatts — real power-plant-scale capacity — that utilities could tap when demand spikes.

The catch: this doesn't replace big batteries. Large installations are still needed to soak up wind and solar power and meet rising electricity demand. And batteries in homes and e-bikes come with their own fire-safety worries, which is exactly why some cities stay wary. Small batteries are a helpful side dish, not the main course.
