White‑Label ODM for North American Importer | US‑Spec Home AC EV Chargers

Client Type: Professional North American import brand owner with solid offline distribution networks and online retail channels for residential new‑energy products.

Product in Scope: 7.7kW / 9.6kW / 11.5kW US‑spec wall‑mount Level 2 home AC EV chargers (three power variants)

Cooperation Model: ODM White‑Label. Mature mass‑production hardware & software platform, custom branding and export packaging without core‑hardware modification.

This North‑American brand aimed to scale Level 2 home EV charger sales across US residential markets. Previous supplier partnerships brought repeated setbacks in product stability, landed cost and after‑sales support, failing to meet strict US market requirements. The key challenges were as follows:

1. High North‑American market‑access barriers with incomplete compliance documentation US market requires NRTL safety listing for EV charging hardware. Former suppliers delivered products lacking valid safety certification, which caused failures in local electrician inspections, blocked offline retail access and brought marketplace delisting risks.
2. Mandatory ENERGY STAR qualification required for mainstream retail channels The client needed ENERGY STAR certification to qualify for major home‑improvement retail chains and local incentive programs, so as to expand sales coverage and improve brand competitiveness. The base hardware had no pre‑existing ENERGY STAR registration at project kick‑off.
3. Lack of dedicated technical resources and fragile after‑sales infrastructure The client’s team focused on sales & channel development, with limited in‑house EV‑charging technical expertise. They struggled with on‑site installation guidance, fault diagnosis and technical support, resulting in slow after‑sales response and high end‑user complaint rates.
4. Insufficient packaging performance for full‑container ocean shipment Most North‑American orders are shipped as FCL full containers. Standard packaging offered inadequate shock‑resistance for long‑haul sea transit, leading to high in‑transit damage rates. Extra replacement units and reverse‑logistics costs continuously eroded profit margins.
5. Brand differentiation requirement via white‑label customisation The client required custom logo silk‑printing, nameplate and export packaging on proven mass‑produced chargers. No hardware or firmware changes were needed; they wanted fast‑to‑market private‑label products for competitive retail positioning.

As a professional EV‑charger manufacturer based in Zhuzhou, China, Zopoise has long‑standing R&D and manufacturing experience for US‑spec chargers. We deliver a one‑stop white‑label ODM service covering 7.7 kW, 9.6 kW and 11.5 kW wall‑mount models, with validated hardware platform, ETL & FCC certifications, high‑volume production capacity and end‑to‑end technical after‑sales support.

1. Valid ETL & FCC certifications for market entry Our three US‑spec charger power variants hold ETL and FCC certification. Complete test reports and technical dossiers are provided to support electrician field acceptance and e‑commerce platform listing approval.
2. Project‑specific ENERGY STAR certification support for the client Since there was no pre‑existing ENERGY STAR registration for this product line, Zopoise coordinated the full certification process on the client’s behalf. We supported all required testing and documentation work to obtain official ENERGY STAR qualification, unlocking access to US retail chains and incentive‑eligible projects.
3. Round‑the‑clock professional technical after‑sales backup Our dedicated technical team offers ongoing support including installation guidelines, fault troubleshooting, technical consultation and standardised repair workflows. We fill the client’s technical gaps, accelerate response for North‑American end users and reduce brand‑related complaint risks.
4. Optimised FCL‑oriented packaging to minimise ocean‑shipping damage Packaging structures are engineered for long‑distance maritime transport: enhanced shock‑absorbing materials and reinforced stacking performance mitigate vibration and humidity during full‑container transit. Transit‑related damage rates are significantly lowered, cutting the client’s overall operational costs.
5. Flexible white‑label customisation with zero hardware modification for fast launch Custom logo silk‑printing on charger housings, rating nameplates and outer cartons are supported on our existing mass‑production platform. No re‑engineering is required, shortening lead‑time for private‑label product roll‑out in the North‑American market.

The client successfully launched 7.7kW / 9.6kW / 11.5kW home EV chargers across online retail and local offline channels in the United States. Supported by our ETL & FCC certifications, project‑secured ENERGY STAR qualification, consistent product quality, shipping‑optimised packaging and comprehensive technical support, the client resolved historic pain‑points including insufficient compliance, high field‑failure rates, inefficient after‑sales handling and logistics damage.

Stable end‑user feedback was achieved, product return‑and‑repair rates dropped substantially, and overall profit margins improved. Initial trial orders grew into sustained high‑volume white‑label ODM collaboration, empowering the client to expand further within the North‑American residential EV‑charging segment.
