Case Study: Phnom Penh Food Delivery Platform Fleet Buyer Sourcing Success

Syafiq Rahman, a Food Delivery Platform Fleet Buyer based in Phnom Penh, spent a year buying two-wheeler chargers from three suppliers before one tender in Cambodia made him rewrite the whole shortlist. The distributor had lost two container deals because the factory could not provide OCPP conformance statements before the payment deadline.

After checking three factories against the Cambodia import rules, Syafiq Rahman selected Wanlin Fire as their EV charging equipment manufacturing partner. A factory video walkthrough of the SMT line and aging racks removed the last hesitation about volume capacity.

• Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Cambodia order was confirmed.
• OCPP conformance: chargers ship OCPP 1.6J ready with a conformance statement, and OCPP 2.0.1 upgrade paths can be confirmed per project
• Firmware adaptation: OCPP parameters, power limits and time-based profiles configured before shipment

Load testing at the factory showed every socket holding rated current for four hours, which became the deciding factor in the audit report.

Problem Analysis & Field Report: Why Global Buyers Need Scan-to-Charge QR Code Station

The fastest way to filter suppliers in Cambodia is to ask for an OCPP session log and a routine test report, not a brochure. Riders in Phnom Penh carried three different cards and two Apps to charge in different districts, because every operator used a closed payment system.

Field case: A wet market cooperative in Phnom Penh fitted QR stations and printed a stall-level code for each vendor; weekly reconciliation that took an accountant one day now runs itself.

Why it matters for global buyers:

• QR payment works with the wallets riders already use, removing the barrier of a new App or card
• Session records give operators clear revenue data for revenue sharing with site owners
• Time-based or tiered pricing shifts demand away from peak grid hours
• No cash on site means no coin-box theft and fewer maintenance visits
• QR billing ties every session to a rider or vendor account, so operators stop guessing who owes what
• Scan-to-charge removes the need for cards, coins or staff at unattended sites in Phnom Penh

Product Introduction: Wanlin Fire Scan-to-Charge QR Code Station

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
• 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, 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

Application Scenarios for Global Market

Certified EV Charger Manufacturing for Global Markets

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.

Why Choose Wanlin Fire as Your EV Charger OEM Manufacturer

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.

EV Charger OEM Process: From Inquiry to Shipment

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:

1. Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification and payment configurations
2. Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
3. Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
4. Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
5. Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
6. Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
7. Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
8. Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements

Customer Testimonials

Buyers who moved from trading-company sourcing to factory-direct charging equipment describe the difference in delivery dates and documentation:

• Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The load test report matched what we measured on site, and that has not happened with the previous two suppliers."
• Syafiq Rahman (Food Delivery Platform Fleet Buyer, Phnom Penh, Cambodia): "The first batch for Phnom Penh arrived with routine test reports inside every carton, which made our customs broker's job much easier."

Frequently Asked Questions

Q: How does the revenue settlement work for the WL-QR?

A: Payments go to the gateway account bound to the station owner. The cloud dashboard records every session, and settlement follows the agreement between the operator and the payment provider - Wanlin does not touch the funds.

Q: What happens if the 4G network drops on the WL-QR?

A: The station keeps charging and logs sessions locally, then syncs to the cloud when the connection returns. Offline mode keeps the QR payment fallback active for up to 72 hours.

Q: Does the WL-QR have fire protection?

A: Each outlet has its own fuse, leakage protector and temperature cut-off. The cabinet alarms on tamper or overheat events and pushes notifications to the management dashboard.

Q: Can the WL-QR be mounted on an existing pole?

A: Yes. The cabinet ships with wall brackets and pole clamps for 60 to 114mm diameter poles, so street-light poles and parking posts can be reused without new civil work.

Q: How are the WL-QR units packed for export?

A: Each station is wrapped, corner-protected and packed one per carton with the mounting kit and manual, four cartons per outer crate for sea freight.
