Copper develops battery-integrated appliances that make home electrification easier and more affordable.
Copper
Battery-Backed Induction Stove
30" induction range with an integrated battery that plugs into a standard 120V outlet. No electrical panel upgrades required.
Description
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.
Cost Savings
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.
Key Differentiators
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

About
Decarbonization Impacts
Operational Emissions
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.
Embodied Carbon
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.
Project + Building Compatibility
Project Type
Both existing building retrofits and new construction
Essential Building Characteristics
Standard 120V/15A outlet within reach (no extension cords). 30" wide opening. Stove weighs 354 lbs.
Ideal Building Characteristics
Multifamily buildings — especially older buildings where electric panel upgrades are cost-prohibitive — and any home where adding a 240V circuit isn't practical.
Minimum Project Size
1 stove. Copper sells single units to homeowners and units at scale to multifamily housing providers.
Ideal Project Size
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.
Additional Considerations
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.
NY Contractor Availability
Copper has built an active network of vetted New York installers.
Other Screening Criteria
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.
Example Installations
Installed By
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.
Case Studies
Additional case studies from the NYCHA deployment will be shareable as initial installs go public.
Resident Experience
During Installation
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.
Post Installation
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.
Financing
Upfront Costs
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.
Ongoing Costs
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.
NY Incentives/Financing Resources
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.
Payback Period
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.
Operations, Management, and Maintenance
Operations and Maintenance Requirements
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.
Ease of Operations
Onsite training included for multifamily deployments, typically 30 minutes per resident cohort. Multilingual quick-start guide and full user manual are provided.
Service Support
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.
Data + Performance
Copper can monitor system performance over time to identify and address ongoing issues.
Future Proofing
The Charlie stove removes a building's exposure to gas shutoffs from LL152 inspections. Once a unit installs Charlie, that kitchen no longer depends on gas. Portfolio owners running LL152 risk assessments can use Charlie to take the kitchen line item out of the gas-dependence equation. Charlie is also Virtual Power Plant-ready, with grid services and tariff-aware charging capabilities in development. Buying today doesn't lock owners out of future grid revenue.
Specifications
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.
