Case Study: Siem Reap Condo Strata Charging Project Manager Sourcing Success

Chanrithy Meas runs charging procurement for a group that operates in Siem Reap and two neighbouring provinces, so grid voltage and rain protection mattered more than the lowest quote. A monsoon-season inspection in Siem Reap found rusted pins on three outdoor sockets that had never been rated for rain.

After two rounds of document checks, Chanrithy Meas 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.

• Site replication: the same wallbox model had been running under a tropical downpour test for 30 days before the Cambodia order was confirmed.
• Regional paperwork: CE / FCC / RoHS certificates plus OCPP 1.6J conformance statements were prepared for the Cambodia importer and attached to the commercial invoice.
• Private label: your brand on the enclosure, LCD screen boot logo, packaging and the mobile App name

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 App Payment Timer Charger for E-Bikes

Every failed charger in Siem Reap had one thing in common: nobody checked the IP rating against the installation site before ordering. A motorcycle shop in Cambodia offered charging as a side service but lost money because customers left bikes plugged in overnight.

Field case: A market in Siem Reap installed coin-and-App chargers; riders without wallets used coins, tourists scanned, and utilization reached 24% across both groups in the first month.

Why it matters for global buyers:

• Dual coin and App payment covers users with and without smartphone wallets
• Timer countdowns end overstay and make socket turnover predictable
• Coin operation works during power or network outages when App payment cannot reach the server
• Session logs reconcile coin drops with App records for operators and auditors
• Timer control caps each session, so one rider cannot occupy a public bay for the whole evening
• Coin and app options suit markets where cash is still common and riders without smartphones are regulars

Product Introduction: Wanlin Fire App Payment Timer Charger for E-Bikes

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

Wanlin Fire positions itself as the manufacturing partner behind local charging brands, offering private label, payment customization and after-sales spare parts rather than a closed hardware box.

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

A typical Wanlin Fire OEM project begins with the target market, because voltage, certification and payment habits decide the hardware configuration. 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): "Our logo, the App name and the payment gateway were all configured before the first container left the factory."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 24%."
• Chanrithy Meas (Condo Strata Charging Project Manager, Siem Reap, Cambodia): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."

Frequently Asked Questions

Q: Why keep coin payment on the WL-TM?

A: In many markets a large share of two-wheeler riders still pay cash. The dual-flow design keeps those riders served while the QR option captures card and wallet users.

Q: How is the coin box emptied and audited?

A: The box sits behind a security lock. The counter log records total coins per day, so the collection tally can be checked against physical coins in minutes.

Q: Can pricing differ by outlet on the WL-TM?

A: Coin pricing is set per cabinet, while app pricing can differ per outlet. Operators commonly run uniform coin pricing and time-based app tiers.

Q: What happens when the timer ends?

A: The outlet powers off and the LED goes dark, freeing the slot for the next rider. The vehicle cannot keep drawing current once the session closes.

Q: Does the WL-TM replace old resistor-panel stations?

A: Yes. It mounts on the same wall footprint and reuses the existing supply in most retrofits, which is why property managers choose it for legacy upgrades.
