Cheng Han Wei, a Property Developer Procurement Manager in Can Tho, started with a single pilot site and needed a supplier that could scale from 10 card sockets to 300 without changing platform. Delivery riders were swapping batteries on the street, and two logistics firms had asked the operator to host a shared card-gated charging hub for the neighbourhood.
After reviewing quotes from three countries, Cheng Han Wei selected Wanlin Fire as their EV charging equipment manufacturing partner. In the end the buyer chose the supplier that could ship CE and IEC 61851 documents with the first container, since customs clearance in Vietnam had stalled two earlier orders.
Field engineers in Can Tho 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.
The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network because the payment reader failed twice. A rural market in Can Tho had no stable supply for vendor e-rickshaws; batteries were carried home over rough roads to charge, which damaged packs and morale.
Field case: A rural cooperative in Can Tho ran a solar-charged NFC station for vendor trikes and used the card data to show the utility that daytime charging demand justified a grid connection.
Why it matters for global buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own EV charging product lines for global markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized charging line developed for your market, our team can work with you from model selection through mass production.
Wanlin Fire builds the Off-Grid Two-Wheeler EV Charger for the conditions buyers in Vietnam actually deal with: covered parking, humid air, 220V mains and heavy daily card turnover.

Certification is one of the most important considerations when sourcing EV charging equipment for export. Wanlin Fire can provide real documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certificate information for the exact model they intend to purchase.

For customers exporting EV chargers, Wanlin Fire supports CE, FCC, RoHS and UKCA documentation with per-model files, and for projects where additional testing applies, the relevant documentation and testing path can be arranged for any represented model before ordering. Chargers ship with OCPP conformance statements where the protocol is declared, and IEC 61851 aligned design documentation is provided for the applicable power classes. Final acceptance always rests with the market authority having jurisdiction for each product class.
Buyers who compare factories on price alone usually find the difference in the failure rate; Wanlin Fire competes on tested output, card-reader reliability, protection hardware and documents that survive customs inspection.

The OEM process for a Vietnam importer starts with a voltage, card format and payment survey, then moves to samples, container QC and OCPP backend onboarding. A standard OEM project then follows 8 steps:
Operators who standardized on one OCPP-compatible card-charging line report shorter vendor lists and fewer site visits:
A: Yes, when paired with panels and the optional battery buffer. The station manages the solar input, stores surplus and releases power for charging sessions; grid connection is optional where available.
A: The NFC reader still meters each session and credits the operator account, so a resort or community hall can recover the cost of the solar system over time.
A: For a typical 1000W charging station with a 5kWh buffer, a 1.5kW to 2kW panel array covers daily e-bike demand in tropical sun. Wanlin Fire shares a sizing sheet per site.
A: Yes. When both sources exist, the controller prefers solar and draws from the grid only when the buffer is low, which maximizes the renewable share.
A: The enclosure is IP54 to IP65 and the connector area is sealed for salt-air locations. Coastal projects should confirm the site distance from shore at ordering.
Key result: By working directly with manufacturer Wanlin Fire, Can Tho Property Developer Procurement Manager Cheng Han Wei achieved 39% higher margins while offering competitive pricing. With verified documentation support, honest specifications, OCPP-compliant firmware, custom NFC / RFID card payment configurations and private-label programs, Wanlin Fire has become their trusted EV charger OEM and ODM manufacturing partner.
