Copper's 30" battery-backed Charlie induction stove plugs into a standard 120V/15a outlet — enabling kitchen electrification without rewiring. For buildings with ageing or shutoff gas lines, Charlie simplifies the process for building owners to update or restore cooking service. By eliminating gas combustion, the stove also improves indoor air quality and reduces health and safety risks. In addition, the stove's embedded lithium-ion battery enables it to function for up to two days during a power outage.

- No re-wiring needed - Because the Charlie stove plugs into a standard 120V/15a outlet building owners can switch tenants to electric cooking while avoiding costly rewiring - Minimally-disruptive, quick installation - The Charlie stove can be installed in under 1 hour, without tenant relocation - Integrated resilience + energy efficiency - The Charlie stove's integrated lithium iron phosphate battery not only supports energy efficiency but also provides resilience during outages, allowing for uninterrupted operation - Vetted, local installation support - Copper offers a vetted installer network that has already completed hundreds of real installations in New York

Installing the Charlie stove can save a typical multifamily building between $3K-$15K per unit. Cost savings are higher in pre-war buildings where rewiring is impractical. In buildings with ageing gas infrastructure, avoided gas line decommissioning and replumbing increase cost savings. VPP and demand-response revenue generation are in development with utility pilots underway.

Copper’s energy storage-equipped induction stoves deliver significant environmental and greenhouse gas (GHG) benefits by reducing fossil fuel reliance in homes and optimizing grid energy use. By replacing natural gas or propane stoves, Copper eliminates direct emissions from combustion, including carbon dioxide (CO2), methane (CH4), and nitrogen dioxide (NO2). In a typical household, this transition can cut 80–120 kilograms of CO emissions annually.

The Charlie stove uses lithium iron phosphate chemistry which has a lower embodied carbon than nickel manganese cobalt batteries, and is cobalt-free. The unit is designed for service and module-level battery replacement rather than full replacement, which extends product life.

Both existing building retrofits and new construction

Standard 120V/15A outlet within reach (no extension cords). 30" wide opening. Stove weighs 354 lbs.

Multifamily buildings — especially older buildings where electric panel upgrades are cost-prohibitive — and any home where adding a 240V circuit isn't practical.

1 stove. Copper sells single units to homeowners and units at scale to multifamily housing providers.

No ideal project size, however larger orders unlock pricing and dedicated install support. Copper can install multiple units at a time for multi-unit buildings.

To opperate the Charlie stove, induction-compatible cookware is needed (no aluminum or copper-bottom). For installation, a dedicated 120V/15A outlet within 72" of the stove is ideal, recessed if possible. No additional equipment required.

Copper has built an active network of vetted New York installers.

For buildings with stairs, it's critical to use the right equipment, such as a stair-climbing hand truck or lifting straps, as the stove is heavy. A tour of a specific building is required for multifamily projects to ensure successful installations.

NYCHA; contract for at least 10,000 stoves, deployment underway. Sunrun: pilot agreement. Ava Community Energy: induction cooking education and demo program (CA). Plus thousands of direct-to-consumer customers across the contiguous U.S. Multifamily install counts available under NDA.

Additional case studies from the NYCHA deployment will be shareable as initial installs go public.

Average installation time is less than one hour. This includes the time it takes to remove the legacy range, cap gas lines, and install the Copper range. Copper can be installed with tenants in place.

The Charlie stove offers a number health and wellbeing benefits for residents. Installing the Charlie stove reduces NO2, CO, and PM2.5 from combustion. Fire risk drops substantially: no open flame, no pilot light. The induction surface only heats ferrous cookware so the glass stays cool around the pan. Charlie ships with child lock, auto-shutoff if a pan is removed, overheat protection, and pan-detection so a burner won't power on without cookware. For multifamily owners, eliminating gas in the unit also reduces gas leak risk.

Select gas customers in Manhattan, the Bronx and Staten Island may be eligible for incentives under ConEdison's Energy Exchange program. See Copper's incentives and rebate page for more information on incentives in other jurisdictions.

Pricing starts at $5,999. Multifamily and utility pricing is lower at volume; contact Copper for project pricing. Total installed cost is almost always less than gas-to-electric alternatives once panel upgrades, gas decommissioning, and rewiring are accounted for.

Under typical NY rates and household cooking patterns, residents see roughly $3-$30/month more on the electric bill, partially offset by elimination of any fixed gas service charges if the building drops gas. Charlie's battery charges during off-peak windows where tariffs allow, which can further reduce cost.

Compared to installing a typical 240v induction stove with rewiring requirements, payback period is immediate. Compared to installing a traditional gas stove payback period depends on fuel rates and gas line infrastructure maintenance costs.

Copper can monitor system performance remotely over time to identify and address ongoing issues. No routine maintenance for owners and residents beyond a standard wipe-down cleaning of the glass top.

Onsite training included for multifamily deployments, typically 30 minutes per resident cohort. Multilingual quick-start guide and full user manual are provided.

Copper operates a service team partner network for in-New York service calls. In addition there is a two-year limited warranty on every stove. Most issues are resolved remotely via diagnostics; physical service calls are dispatched same-week in the NYC metro area.

UL 1973: Standard for Batteries for Use in Stationary, Vehicle Auxiliary Power, and Light Electric Rail Applications; UL 9540A: Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Systems UN 38.3: transport safety requirements Copper is actively collaborating with UL to update the 858 standard to formally incorporate batteries. In the meantime, Charlie has passed the applicable protection and performance safety tests of the existing UL 858 standard.
