Case Study: Medan Condo Strata Charging Project Manager Sourcing Success

Kittisak Chaiyasan, a Condo Strata Charging Project Manager based in Medan, spent a year buying two-wheeler chargers from three suppliers before one tender in Indonesia made him rewrite the whole shortlist. Local riders were charging from home extension cords, and the municipal authority had started fining buildings for unsafe cables.

Once the samples finished a two-week weather test in Medan, Kittisak Chaiyasan 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 Indonesia had stalled two earlier orders.

• Spare support: mainboards, payment modules and enclosures are kept as spares for after-sales replacement
• Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
• Documentation: user manuals and installation guides in local languages for your market

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 Portable Low-Voltage EV Charger

Before selecting a charger supplier, a buyer should look at what happens on the street: extension cords crossing sidewalks, batteries carried into apartments and sockets that stop working after the first rain. A tuk-tuk driver in Medan ran out of charge two blocks from a shop that had no wall socket at street level, and pushing the cab home took an hour.

Field case: A roadside assistant in Medan kept a portable low-voltage charger in the service van and recovered 26 stranded e-bikes in the first month.

Why it matters for global buyers:

• Portable units bring a controlled charge profile to sites that lack fixed infrastructure
• Low-voltage 48V-72V output matches two-wheeler packs without step-down adapters
• Protection circuits prevent overcharging when riders plug into unknown sockets
• Field teams carry one tested unit instead of a bag of generic chargers
• Portable units give drivers and workshops a backup path when fixed stations are full or far away
• Low-voltage output protects small packs from the over-current damage seen with car-oriented chargers

Product Introduction: Wanlin Fire Portable Low-Voltage EV Charger

Each Wanlin Fire charger pairs a protected AC-DC stage with an OCPP-ready control board, so operators can manage sessions, pricing and diagnostics from one backend instead of five different Apps.

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

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.

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): "We run the OCPP backend from our office in Indonesia and the wallboxes in Medan have not dropped a heartbeat session since commissioning."
• Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "The first batch for Medan arrived with routine test reports inside every carton, which made our customs broker's job much easier."
• Kittisak Chaiyasan (Condo Strata Charging Project Manager, Medan, Indonesia): "The factory's engineer answered our voltage question in plain language on the same day, and that settled the sourcing decision."

Frequently Asked Questions

Q: Can the WL-PT replace the original scooter charger?

A: For 36V to 72V lead-acid and lithium packs, yes - the output voltage must match the pack, and the connector is matched to the vehicle. It is not for automotive EVs.

Q: Is the WL-PT safe to leave plugged in overnight?

A: The charge curve ends in a float stage and the overheat sensor cuts current if the housing exceeds its limit. We still recommend unplugging once the indicator turns green.

Q: Which plugs does the WL-PT ship with?

A: Common two-wheeler charge plugs are stocked. Buyers send their market plug drawing or sample, and we match or mold it - custom molds start at 500 units.

Q: How is the WL-PT packed for retail?

A: One unit per color box with manual and cable, 20 boxes per export carton. Retail-ready packaging with barcodes is available for volume orders.

Q: What is the MOQ for the WL-PT?

A: Standard units start at 100 pieces. Custom-branded retail packaging starts at 500 pieces with a 20 to 25 day lead time.
