Copper Brings Battery-Powered Charlie Range to Physical Retail Through Royal Green Partnership

Quick Facts

Copper’s Charlie induction range is now available at Royal Green showrooms in New York, New Jersey, and Florida, marking the brand’s first retail partnership.
Charlie plugs into a standard 120-volt outlet and uses an integrated 5 kWh battery to deliver high-power cooking performance, with prices ranging from $6,000 to $6,900.
New York state agencies committed $32 million to develop and deploy up to 10,000 Charlie units in NYC public housing facilities.

Copper is taking its Charlie induction range into physical retail for the first time. The Bay Area startup announced a partnership with Royal Green Appliance Companies on Sept. 2, bringing Charlie to showrooms in Manhattan’s Tribeca neighborhood, White Plains, Long Island, and Parsippany, N.J. Through Royal Green’s Good Deals Appliances network, the range will also appear in Fort Myers and Naples, Fla.

Before this deal, Copper had sold a few thousand units through direct-to-consumer channels and to rental building operators. The Royal Green partnership opens in-person demonstrations to a broader consumer base.

Charlie is the world’s first battery-equipped induction range. It plugs into a standard 120-volt outlet and relies on an integrated 5 kWh lithium iron phosphate battery to deliver power typically requiring a 240-volt connection. The battery charges when electricity rates are lowest, then draws down during cooking. It can sustain three to five meals during a power outage.

The full-sized range includes a ceramic glass cooktop, a 4.5 cubic-foot oven, wooden dials and handle, and a large LCD display. It comes in stainless steel, Sea Salt White, and Azurite Blue, priced between $6,000 and $6,900.

CEO and co-founder Sam Calisch said the move to physical retail reflects the nature of buying premium appliances. “Buying a premium appliance is a hands-on experience. People want to see how it works, cook on it, open the oven, and ask questions,” Calisch said. “Partnering with Royal Green gives customers exactly that experience while helping introduce a new category of home appliance.”

Because Charlie draws power from its battery rather than directly from a wall outlet, it also avoids the buzzing noise some induction cooktops produce, Calisch noted. The battery-first design also lets Copper run live cooking demos in showrooms without special electrical hookups.

Royal Green Chief Commercial Officer Stuart Stone described a recent showroom moment that illustrated the product’s market fit. A customer on Long Island wanted to replace a gas range but had only a 110-volt outlet. A salesperson told the shopper nothing existed for that setup. Stone stepped in, showed the customer Charlie on a computer, and invited them back days later. “It fit their bill, and they bought it right there,” Stone said.

New York was a deliberate choice for the first retail push. Copper had already built relationships with the New York Power Authority, the New York State Energy Research and Development Authority, and the New York City Housing Authority through the Induction Stove Challenge. That program includes a $32 million commitment to develop and deploy up to 10,000 Charlie units in NYC public housing. A $1.2 million pilot phase funded by NYSERDA launched in November 2025, placing prototype units in 100 NYCHA apartments. A large-scale purchase order of up to 10,000 units depends on successful pilot results.

Calisch framed Charlie’s core value as removing the installation barrier that has slowed induction adoption. “We’re making ‘going electric’ like an appliance swap instead of a construction project,” he said. “Rewiring a 100-unit apartment building is such an expensive proposition that basically no one’s doing it.”

The range debuted at CES 2025 and earned praise from the New York Times’s Wirecutter, which called it the “Tesla of induction stoves.” Reviewer Rachel Wharton wrote that Charlie “could be the holy grail of induction.” Chef Christopher Kimball has also endorsed the product.
