Q1: Is your AC EV charger compatible with OCPP? Which version?
A: Yes. Our AC chargers are compatible with OCPP 1.6 JSON by default — the most widely adopted version among CPO platforms globally. This means you can plug our chargers into your existing CSMS without extra gateways or protocol converters. We also offer OCPP 2.0.1 upgrade option for projects requiring advanced features like smart charging and transaction data granularity, which is increasingly required for EU AFIR compliance.
Q2: Can your chargers connect to any CSMS (Charge Station Management System)?
A: Yes, as long as the CSMS supports OCPP. OCPP is an open protocol designed to prevent vendor lock-in. Whether you use a CPO platform like AMPECO, GreenFlux, Monta, or your own custom-built CSMS, our chargers can communicate with it over 4G, or Ethernet.
Q3: What communication options (4G, Ethernet, Wi-Fi) do you offer?
A: We offer 4G LTE (Cat 1 or Cat 4) with global band support, and Ethernet for stable wired connections. Many customers prefer 4G with IoT SIM cards for remote sites without network cabling — you choose what works for your deployment. We can pre-configure APN settings based on your local mobile carrier. RS485 port is also available for local meter connection or load balancer integration.
Q4: Do your chargers support smart charging and load balancing?
A: Yes. Our AC chargers support dynamic load balancing, which adjusts charging current in real time based on available site power capacity. This allows you to install more chargers on the same grid connection without tripping breakers. We also support external energy meter integration (MID-certified meters) for accurate consumption billing. For DLM function, currently our technology has a limit of 5m/ 10m distance between the charger and the panel box.
Q5: What remote management features are available for CPOs?
A: Through OCPP connectivity to your CSMS, you can monitor real-time charger status (online/offline/faults), start/stop sessions remotely, view session data and Charge Detail Records, update firmware over the air, set dynamic tariffs and pricing rules, and receive fault alerts. Your CSMS handles the CPO features — we ensure the hardware delivers full OCPP capabilities without restrictions.
Q6: What certifications are required for CPO tenders and public projects?
A: For EU public tenders, CE marking (EN IEC 61851 series) is mandatory. For major infrastructure projects, OCPP compliance is typically required to ensure interoperability. For US NEVI-funded projects, UL 2594 certification and OCPP compliance are required. We provide certification documentation and can work with accredited labs for project-specific testing if needed.
Q7: Do your chargers support RFID authentication and payment integration?
A: Yes. Our AC chargers support RFID/NFC card readers for user authentication. For payment integration, your CSMS handles the transaction — our charger simply sends start/stop signals and meter readings via OCPP. This means you can integrate any payment gateway (credit card, QR code, mobile app) through your CPO platform without hardware changes.
Q8: What is the typical uptime and reliability of your chargers in commercial deployments?
A: We have a real-world deployment of 100 wall mounted EV chargers operating in domestic market; and over 1000 units of Level 2 wallbox AC chargers operating in parking lots of HongKong, China. In both cases, the chargers have been stably operated over a year with no major failures or downtime complaints. The chargers use Ethernet cables and Bluetooth & App, communicating via the OCPP 1.6J or domestic Yun Kuaichong protocol to the operator's payment platform. The operator enjoys steady income, and local businesses and residents get reliable charging. That's the kind of real-world result we stand behind.
Q9: Do you offer ongoing firmware updates and technical support for CPO partners?
A: Yes. We provide over-the-air (OTA) firmware updates via OCPP for bug fixes and new feature rollouts (such as updated certification requirements). For CPO partners with ongoing projects, we assign a dedicated technical account manager. Support is available 24/7 via email, WhatsApp, and video call for urgent issues. We also help you integrate our chargers into your CSMS during onboarding — including APN setup, OCPP endpoint configuration, and online commissioning guidance.
Q1: What is your MOQ (Minimum Order Quantity)?
A: We accept flexible MOQ based on your business model. Sample orders: 1-9 units for market testing. OEM/ODM production orders: typically 100-1000 units per portable model, and 100-500 units per wallbox model, depending on customization level. Container orders (full container load) get priority production scheduling and better pricing. Trial orders for new partners are negotiable. Contact us with your estimated annual volume for a tailored MOQ plan.
Q2: Can I put my own brand/logo on your chargers? What does OEM branding include?
A: Yes. We offer full OEM branding services. This includes custom logo placement on the enclosure, custom packaging design, label layout and materials, Pantone or RAL color matching for housing, and localized user manuals with your brand name. We also support private label programs where the entire product is rebranded as yours. The EV charger firmware and app interface can also be customized with your brand identity.
Besides, some countries or regions require local certification which require the source certificates from us. We can also help with that.
Q3: What is your typical lead time for OEM/ODM orders?
A: Sample lead time: about 3 days for white-labeled existing designs.
Lead time for bulk goods: around 25~35 days for orders of 100 units or more, including custom branding, packaging, and labeling work. Full container orders (1000+ units) typically take 35-45 days, depending on customization complexity. For large projects, we can stagger shipments to match your inventory needs.
Q4: What packaging options do you offer? Can packaging be customized?
A: Standard export packaging: carton boxes with foam inserts, suitable for sea and air freight. We also offer upgraded packaging: individual color boxes for retail display, branded master cartons, and custom inserts designed for specific charger models. All packaging can be printed with your brand elements and product information. Small trial orders use standard protective packaging at no extra cost.
Q5: Do you offer sample units before bulk orders? How does the sample process work?
A: Yes. Sample MOQ is 1 unit. Sample lead time is around 3~7 days. You pay the sample cost plus shipping. If you proceed with a production order, we can also deduct the sample cost from your first invoice. For customized samples (with your logo or specific modifications), sample cost and lead time depend on the scope of work. We also offer sample testing support — we can assist with third-party lab coordination for market entry testing.
Q6: What payment terms do you accept?
A: We usually accept T/T (Telegraphic Transfer). For first-time customers, the typical terms are a 30% deposit, with the balance due before shipment. Small sample orders can be paid via T/T or SWIFT. Large production orders are generally handled via T/T or L/C (through Sinosure).
Q7: Do you offer exclusive distribution rights for specific markets?
A: Yes, on a case-by-case basis. If a distributor commits to annual volume targets and invests in local marketing, we can offer exclusive or semi-exclusive rights for a defined territory (country or region). Exclusive agreements typically include MOQ commitments, marketing support, and technical training. We also protect your IP by not selling to other buyers in your territory once exclusivity is granted. Terms are negotiated per agreement.
Q8: What after-sales support and warranty do you provide?
A: Standard warranty: 2 years for AC EV chargers, covering manufacturing defects. Extended warranty up to 5 years available upon request (cost varies). We provide spare parts for common replaceable components (PCBA motherboards, cables, RFID readers, LCD screens, etc). Technical support is available via email, WhatsApp, or video call.
Q9: Do you offer dropshipping services for online retailers?
A: We work with distributors or wholesalers, not directly with end consumers. However, for established partners, we can ship orders directly to your customers on your behalf. You provide the shipping labels and customer details, we handle packing, labeling with your brand, and dispatch. This is typically available for partners with consistent monthly order volumes. Contact us to see if your business qualifies.
Q10: What trade terms do you support (FOB, CIF, EXW, etc.)?
A: We support EXW (Ex Works), FOB (Free On Board) from major Chinese ports (mainly Shenzhen, Guangzhou), CIF (Cost, Insurance and Freight) to major destination ports, and CFR (Cost and Freight). DDP (Delivered Duty Paid) is available for certain markets and order sizes — we can handle customs clearance on your end, so you receive the goods ready to sell without dealing with import paperwork.
Q11: How do you handle product quality control and inspection for bulk orders?
A: We have a three-stage QC process: incoming material inspection (raw components and PCBs are checked before assembly), in-process quality control (real-time monitoring on SMT lines and assembly stations), and OQC- final testing before packing (each charger undergoes functional testing, including full-spectrum test such as insulation test, output voltage check, communication test, and a simulated charging cycle). We can also arrange third-party inspection (e.g., SGS, TÜV, Bureau Veritas) at your cost, or send you live testing videos/photos upon request.
Q12: What certificates do your products hold for different markets?
A: Our AC EV chargers are certified to CE for the EU market (compliance with LVD, RED and EMC directives based on EN IEC 61851-1). For North America, we offer ETL certification (UL2594 standard, the primary safety standard for EVSE). Certification reports and copies are available for your review. If you need certification for a specific country, we can work with you to obtain it — we have experience with TÜV, Intertek, and other accredited labs.
Q1: Can you customize the exterior/enclosure design of the charger?
A: Yes. We offer full enclosure customization. This includes custom shape/industrial design (we can manufacture from your CAD files), color matching (Pantone or RAL), custom logo placement (silkscreen printing on the lens or laser on plastic), material options (PC/ABS, polycarbonate, metal), and different surface finishes (matte, glossy, textured). We have already showed some new designs of exterior for mold development. Browse our EV Charger Design category for new design concepts we're working on. If none catch your eye, we can design an entirely new exterior based on your ideas. Minimum mold development cost applies.
Q2: Can you rework the PCB/main control board according to my technical requirements?
A: Yes. We have in-house R&D engineers with 15+ years of experience in power electronics. We can design custom PCBA for your project, including customized MCU firmware, specific protection features (over-current, over-voltage, over-temperature, ground fault, surge protection), customized communication modules (Wi-Fi/4G/Ethernet/RS485/BT configuration), and specific metering/precision requirements. The internal PCBA of our new designs category is the same as our regular models, but we can rework it entirely based on your specifications.
Q3: What are SKD and CKD? Do you support both?
A: Yes.
- SKD (Semi Knocked Down) means we assemble the PCBA and main electronics, and/or provide part of other main parts of EV chargers like cables or enclosures, then you assemble the enclosure and final assembly locally (reduces shipping volume and import duties).
- CKD (Completely Knocked Down) means we send you fully disassembled components — PCBA, enclosure parts, cables, connectors, mounting hardware — and you do full assembly and testing locally (maximum tariff benefit, but requires your local assembly capability). We offer both models and provide assembly support and documentation. MOQ for SKD/CKD programs is usually 1000sets, while it is also negotiable.
Q4: Can you provide white-label solutions (my brand, no manufacturer branding)?
A: Yes. White-label means the charger carries no manufacturer branding — everything is yours. We remove all Zopoise branding from the product and packaging. The enclosure, labeling, user manual, too. We also offer pure hardware-only supply (no software) where you integrate our hardware into your own ecosystem.
Q5: What software customization options do you offer (App UI, backend, protocols)?
A: White-label mobile app for home EV chargers (iOS & Android) with your brand name, logo, and color scheme — basic app includes start/stop, schedule charging, real-time current/voltage/power display, charging history, and fault alerts. For commercial EV chargers, OCPP 1.6/2.0.1 pre-configured to your CSMS endpoint (most flexible, works with any CPO platform). Custom app UI design (your visual identity, layout changes, added features).
Q6: What's your minimum order quantity for custom OEM projects?
A: This depends on the level of customization. Sample orders (1-9 units) available for evaluation with existing designs. Logo and label changes — MOQ as low as 100 units. New color including finish on existing enclosure — MOQ around 500 units. Full custom enclosure with new mold — MOQ typically 500-1000 units depending on mold cost sharing arrangement (mold cost can be amortized over a smaller initial order if you accept higher per-unit pricing). Custom PCBA/firmware — MOQ negotiable, typically 500-1000 units.
Q7: How long does custom mold development take? What is the cost?
A: Mold development typically takes 30-45 days from design confirmation to first samples. Mold cost (based on a service life of 200,000 cycles) varies based on complexity and size — entry-level wallbox upper housing molds start around $8,000; more complex designs or larger enclosures range $9,000-$15,000. We can share mold cost if you commit to volume purchase — the cost is amortized over your order quantity.
We provide 3D design support and prototyping before final mold cutting. Once mold is made, production lead time is approximately 30-35 days.
Q8: Do you support ODM (full product development from concept to production)?
A: Yes. ODM means we take your concept or specification and develop the complete product — from initial design to engineering validation, prototype, testing, certifications, and mass production.
This includes hardware design (schematics, PCB layout), enclosure industrial design, firmware development, CSMS platform integration, testing, and certification support.
You own the design as your exclusive product (we do not sell your ODM design to other buyers). ODM projects typically take 3-6 months from concept to mass production, depending on complexity.
Q9: Can I get a sample of a custom design before mass production? How does it work?
A: Yes. Custom sample process:
Step 1 — define requirements (spec, design brief, target price).
Step 2 — we send 3D renderings and electrical schematics for your approval.
Step 3 — sample unit built and tested internally.
Step 4 — sample shipped to you for evaluation (testing, fit, finish).
Step 5 — any revisions made (typically 1-2 rounds included).
Step 6 — sample approved, then mass production begins. Custom sample lead time: 7~15 days depending on complexity. Sample cost is deducted from your first production order if you proceed.
Q10: What certifications can you help with for custom products?
A: We have in-house testing capabilities (2,000 sqm lab with CNAS, UL WTDP, and TÜV witness lab qualifications) primarily for our parent company's lighting products, but we apply the same strict testing discipline to all our chargers. We can help you obtain CE (EU), UL (North America), CB (global mutual recognition), UKCA (UK), and other country-specific certifications. For custom PCBA designs, we guide you on design-for-compliance — ensuring the design incorporates required safety margins and protection features from the start. We work with accredited labs and can manage the certification process on your behalf.
Q11: Do you protect our design and intellectual property in OEM/ODM projects?
A: Yes. We sign a legally binding Non-Disclosure Agreement (NDA) before any project discussion. For ODM projects where you own the design, we commit in writing that we will not manufacture the same design for any other buyer. All CAD files, schematics, firmware source code, and bill of materials remain your property. We have secure data management and access control systems in place. Custom tooling molds are also your property (or you can opt for mold amortization arrangement).
Q12: How do we start an OEM/ODM project with you?
A: Step 1: Send us your requirements — target market (region), desired specifications (power, connector type, communication), target price range, estimated annual volume, and any reference designs or competitor models you like.
Step 2: We review feasibility and send you a proposal with timeline and estimated costs.
Step 3: Sign NDA and development agreement if needed.
Step 4: We deliver 3D renders and electrical schematics for your approval.
Step 5: Sample production and testing.
Step 6: Sample approval and mass production. We've worked with distributors, CPOs, and brands across Europe, North America, the Middle East, South Asia, Southeast Asia, Africa, and Latin America — and we're ready for your project too.
