Stronger together

The largest energy transition in history is here. Distributed battery energy storage helps everyone.

We make appliances with integrated battery energy storage.

The home of the future is full of batteries. Imagine dedicated energy storage in every appliance you own allowing it to work seamlessly regardless of weather, grid demand or whatever life has in store.

Every battery energy storage equipped appliance smooths local grid demand and ensures energy is available for everyone in your community no matter when it's needed.

Our vision is a fleet of battery powered appliances, responding to your needs and the needs of the our planet, together.

Copper's appliances deliver tons of power without requiring major home electrical upgrades making the upgrade to electrification easy and obvious.

Gas is poison

Let's clear the air.

You wouldn't leave your car running in the garage; why would you burn gas in the kitchen?

Children in homes with a gas stove are 42% more likely to develop asthma.

Induction stoves are more powerful, more consistent, and easier to clean.

Why a range?

Dinner time is when the mix of electricity on the grid is dirtiest. So why use it?

The battery in Charlie charges when the grid is cleanest, avoiding fossil fuels in the kitchen and out on the grid.

"This could be the holy grail of induction, as far as I’m concerned."

Rachel Wharton, Wirecutter, The New York Times

"New stove that plugs into a normal wall outlet could be major gain for health and the climate"

Isabella O'Malley, The Associated Press

"Copper’s stoves use a lithium-iron phosphate battery — the same type found in many electric vehicles — to store energy and contribute it toward cooking heat."
Hilary Howard, The New York Times
"Using battery-equipped stoves as distributed storage networks that lessen needs for gas-fired peaker plants during high demand."

Ben German, Axios

"Switching from gas to electric? Here are 3 appliances that are easy to install"

Jeff Brady, NPR

"Someone please buy me this battery-powered, plug-in induction range."

Amy Skorheim, Engadget

"I like that it has a soft, natural look even though it's a high-tech item."

Lisa McManus, America's Test Kitchen

"Berkeley-based Copper was selected to supply 10,000 stoves to the New York City Housing Authority."

"Take the knobs on the induction range from Copper. Made of walnut, they let cooks know, without looking, the level of heat they’ve set a burner to."

Christopher Mims, The Wall Street Journal

"Both the convection oven and the cooktop have better temperature control than the gas alternative."

Adele Peters, Fast Company

"Handsome battery-powered induction stove revolutionizes home cooking"

Ian Baker, New Atlas

"A good example of how clean tech is coming to our homes in a meaningful way."

Adam Clark Estes, Vox

"[Charlie] draws on the trickle of electricity from a 120-volt outlet to charge its own battery, allowing it to provide the bursts of power needed for cooking even without a 240-volt socket."

Induction Delivers

Powerful. Steady. Clean.

Smokin’ searing, smooth simmering, and everything in between.

"For the vast majority of cooking that the average American home cook does, an induction burner will perform as well or better than a typical gas range." - J. Kenji López-Alt, Gear Patrol
