Case Study: Ho Chi Minh City Shopping Mall Facility Buyer Sourcing Success
Somsak Ratanawong, a Shopping Mall Facility Buyer in Ho Chi Minh City, needed a charging line that property managers would approve and riders could pay for with a card or a wallet, without a dedicated app for every site. Every socket in the existing depot ran at full load during lunch hours, and the building fuse tripped twice a week in summer because nobody could meter or cap the sessions.
Once the samples finished a two-week weather test in Ho Chi Minh City, Somsak Ratanawong selected Wanlin Fire as their EV charging equipment manufacturing partner. Documentation decided it: CE / FCC / RoHS files and an OCPP 1.6J conformance statement arrived with the samples, ready for customs.
- Export experience: the factory ships card-activated charging equipment to Southeast Asia, South Asia, Africa, Latin America and the Middle East.
- OCPP conformance: chargers ship OCPP 1.6J ready with a conformance statement, and OCPP 2.0.1 upgrade paths can be confirmed per project.
- OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V), socket counts and card formats.
Field engineers in Ho Chi Minh City mounted the units, enrolled the first batch of NFC cards, tested QR fallback payment, and left the property team with a one-page operating checklist.
Problem Analysis & Field Report: Why Global Buyers Need 20-Outlet EV Charging Cabinet
Every failed charger in Ho Chi Minh City had one thing in common: nobody checked the IP rating or the payment module against the installation site before ordering. A dormitory in Ho Chi Minh City let 50 students charge e-bikes in a bike room with six wall sockets; the room breaker tripped every night and bikes blocked the exit.
Field case: A dormitory operator in Ho Chi Minh City installed 30-port NFC cabinets in a ventilated shed with per-port breakers; the fire marshal approved the layout and riders paid per session by card.
Why it matters for global buyers:
- High port counts charge an entire dormitory or staff fleet from one engineered supply point
- Per-port breakers and over-temperature shutdown isolate a failing battery instead of taking down the row
- Card billing recovers electricity cost and caps how often each account can charge
- Outdoor-rated cabinets move charging out of corridors and lift lobbies where fire risk concentrates

Product Introduction: Wanlin Fire 20-Outlet EV Charging Cabinet
Wanlin Fire builds charging stations around three things riders and operators actually measure: reliable output under load, payment methods people already use and certificate files that clear customs.
Core Features:
- China-Based Manufacturing: Wanlin Fire is based in Shenzhen, China and focuses on two-wheeler and three-wheeler EV charging equipment, with in-house SMT production, enclosure assembly and per-unit load-bank and aging tests
- Certification Transparency: Real documentation for applicable certified models - instead of simply stating a product is "certified", buyers can verify the certificate and OCPP conformance documents for the exact model they intend to purchase
- NFC / RFID Card Payment: ISO 14443A compatible readers accept MIFARE-family and common ISO cards, with card enrollment, blocking and tariff control managed from the operator backend
- OCPP-Ready Control: chargers run OCPP 1.6J compliant firmware with 2.0.1 upgrade paths, so operators connect to their own CSMS instead of a closed vendor cloud
- Private Label Support: color, logo, card design, payment module, voltage, packaging, manuals and firmware parameters customized according to project requirements
- Global Market Experience: we work with distributors, operators and fleet owners worldwide and understand export steps, certification questions, local payment habits, labeling preferences and tender submission needs

EV Charger OEM Process: From Inquiry to Shipment
A typical Wanlin Fire OEM project begins with the target market, because voltage, certification, radio rules and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification, card format and payment configurations
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, card design, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials
Importers who moved from white-label resellers to factory-direct supply in Vietnam usually mention the same shift.
- Raj Kumar Pillai (Property Developer Procurement Manager, Penang, Malaysia): "The load test report matched what we measured on site, and the reader enrolled our test card on the first tap; that has not happened with the previous two suppliers."
- Putu Arimbawa (Charge Point Operator, Bandung, Indonesia): "We run the OCPP backend from our office in Indonesia and the NFC stations in Bandung have not dropped a heartbeat session since commissioning."
- Somsak Ratanawong (Shopping Mall Facility Buyer, Ho Chi Minh City, Vietnam): "The first batch for Ho Chi Minh City arrived with routine test reports inside every carton, which made our customs broker job much easier."
Frequently Asked Questions
Q: Why choose a cabinet over several single sockets?
A: A cabinet concentrates metering, protection and payment in one enclosure on one feeder, which is cheaper to install and maintain than wiring many individual smart sockets across a large parking area.
Q: What is the largest cabinet available?
A: The 30-outlet model runs on a three-phase feed and is built for estate courts and factory sheds. Bay current is set per outlet, so a cabinet can mix 5A, 10A and 13A bays.
Q: How do we top up resident cards?
A: Residents pay by QR or bank transfer and the operator adds credit to the card account from the dashboard. The cabinet itself needs no cash handling.
Q: Can the cabinet report to a government or utility platform?
A: Yes, through the OCPP 1.6J connection. Session, meter and status data export in standard format for subsidy, reporting or audit requirements.
Q: What protection is built in?
A: Each outlet has overcurrent and leakage protection, and the cabinet has a master breaker sized to the declared feeder. Surge protection is included on the input stage.
