About

Copper (legally Channing St. Copper Co.) is a Berkeley, California appliance manufacturer building battery-integrated home electrification products. Its flagship product, Charlie, is an induction range with an onboard lithium iron phosphate battery of roughly 5 kWh that lets the stove run from an ordinary 120-volt outlet instead of requiring a 240-volt circuit and a panel upgrade. The company was founded in 2022 and is a certified B Corp; it sells the range direct to consumers along with delivery and installation, and also runs programs for multifamily building owners and appliance installers.

The onboard battery removes the biggest barrier to induction adoption: instead of paying for rewiring and an electrical panel upgrade, the customer plugs the range into a standard 120V outlet, and the battery buffers the bursts of high power that induction cooking needs. The battery also charges off-peak, making the appliance a small grid asset rather than just a load.
