William Hartley, an EV Charger Distributor in Ho Chi Minh City, walked into a supplier search with three hard requirements: OCPP compatibility, real certificate files and a payment method riders already use. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply.
After comparing four shortlisted factories, William Hartley selected Wanlin Fire as their EV charging equipment manufacturing partner. What closed the deal was a load-bank test report showing every output holding rated current, plus the payment module riders already used.
After a factory audit and sample evaluation, the partner placed a first order of 11 charging points and expanded twice within the year.
The real cost of cheap charging equipment shows up after installation: melted sockets, rejected containers and riders who stop trusting the network. A hotel in Ho Chi Minh City wanted to serve delivery riders and guests with e-bikes, but staff could not supervise charging spread across three back rooms.
Field case: A courier hub in Ho Chi Minh City installed dual-gun commercial chargers with load balancing; the depot charged 11 bikes per night without upgrading the incoming supply.
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 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.

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, protection hardware and documents that survive customs inspection.

Wanlin Fire's EV charger OEM services are suitable for: EV charger distributors, two-wheeler EV importers, e-bike brand procurement teams, e-scooter fleet operators, micromobility charging network buyers, e-rickshaw fleet owners, charging infrastructure wholesalers, property developers, delivery fleet managers, retail charger buyers, trading company sourcing managers, community charging project managers, utility partnership buyers and government mobility project officers.
The EV charger OEM process starts with a short qualification call about vehicle types, voltage, site conditions and the payment methods used in your market. A standard OEM project then follows 8 steps:
Buyers who moved from trading-company sourcing to factory-direct charging equipment describe the difference in delivery dates and documentation:
A: On the two-phase 380V input, yes - each gun delivers its rated output. On a single-phase supply, the dynamic load balancer splits available power instead of tripping the main breaker.
A: The cabinet has a sealed bay for standard POS terminals, and the firmware exposes a payment interface for local acquirers. QR code and RFID work out of the box.
A: Hardware is 2.0.1-ready. Current production firmware runs OCPP 1.6J for the widest backend compatibility, and the 2.0.1 stack can be loaded per project once the target CSMS is confirmed.
A: Quarterly visual checks, an annual tightening inspection and filter cleaning. The cabinet reports fan and temperature status over OCPP so servicing can be scheduled before failures.
A: Standard builds ship in 25 to 35 days. Configured units with POS integration or special gun cables run 40 to 50 days including sandbox testing against the buyer backend.
