The Copper Charlie is a home range from Berkeley startup Copper, featuring an internal lithium-iron-phosphate battery that lets its induction cooktop and oven run from a standard 120-V socket. Launched via a gradual spring rollout and now available across the contiguous U.S., the Charlie combines four induction elements with conventional radiant oven elements powered by the onboard battery. Its unique onboard energy storage supplies bursts of current on demand, avoiding rewiring for most North American kitchens.
The unit packs four 8-in (200-mm) induction zones, each rated to about 2.8 kW, plus a high-output oven that preheats faster than typical gas models. The stove manages charger draw to stay below a 15 A circuit threshold and can supply up to 10 kW peak by supplementing mains with stored energy. Copper estimates the LFP battery will last about 20 years and enable multiple family meals during outages.
For consumers, the Charlie offers gas-like responsiveness and precision without costly electrical upgrades, making induction adoption simpler for many households. Its battery-backed design also supports resilience during outages and aligns with decarbonization trends by enabling electrification without rewiring.
