The part of the story that changed the buyer's math For plaza and street bays, the WL-FS7 pairs a floor-standing column with IK10 impact rating and optional bollard guards. Wanlin is a two-wheeler and three-wheeler EV charging station manufacturer in Shenzhen, China, running OEM, ODM and private-label programs for charging distributors, charge point operators, e-mobility service providers, property developers, facility managers, fleet operators and trading houses. Hard numbers from the trial netting the buyer a 39% margin against the previous supplier for importers who source factory-direct, with per-model CE / RoHS / IEC 61851 documentation, OCPP 1.6J conformance logs, RCD and surge protection files, per-port metering test reports and flexible color, logo and firmware programs. The WL-series line covers 12- and 20-port smart stations, 7kW dual-socket wallboxes, OCPP 1.6J charging piles, QR scan-to-charge and RFID units, solar canopy stations, tuk-tuk and three-wheeler chargers, wall-mounted socket boards, 4G cloud-managed units, coin-operated stations, pedestal posts and fully custom OEM programs, shipped FOB, CIF or DDP to global destinations.

The first message asked for a catalog. The real question surfaced two weeks later. Distributors who bought generic charging boards on price alone spent the season managing burned sockets and billing disputes.
Once the field units logged 5,000 charging sessions, Dewi Anggraini selected Wanlin as their EV charging manufacturing partner. The buyer admitted the deciding factor was a supplier who answered protocol questions in hours, not weeks.
Standing in the depot, the buyer ran a full 12-port load while the site breaker held and the display cycled port statuses.
The problem showed up in the field, not in the spec sheet. A plaza operator found floor-standing posts with plastic shells cracked at the base after the first delivery van backed into one.
Field case: A hotel in Bandung chose the WL-FS7 for its drive-up bay after the full-circumference LED ring read clearly from the car. Guest complaints about dead ports fell to zero because status was visible before stepping out.
Why it matters for global buyers:
Wanlin runs OEM and ODM programs for buyers who want their own charging station line without building a factory. Customization covers:
Under the enclosure, the design separates metering from switching so readings stay stable at full load.

Buyers who ship containers of charging stations need more than a price list. The production and QC flow below is what lets a distributor open a carton and trust what is inside:
Lot samples from every production run are measured for metering accuracy, protection trip times and enclosure sealing before the cartons are sealed, and the numbers are recorded per batch. A buyer can request those records with any order.
The buyer compared five candidates on the metrics that caused their previous failures.
| Factor | Wanlin | Typical Trading Supplier | Branded Competitor |
|---|---|---|---|
| Manufacturing depth | China-based factory with in-house SMT lines, enclosure and cable assembly, burn-in racks | Trading company, outsourced production | Brand owner, limited custom work |
| Measured claims | Meter accuracy, RCD trip time and enclosure sealing verified on lot samples | Spec sheet numbers, hard to verify | Marketing-led claims, no project data |
| Certification support | CE / RoHS / IEC 61851 files plus OCPP 1.6J conformance logs per model | Incomplete documents, customs risk | Brand-level only, no per-order files |
| Customization | Colors, logo, firmware, tariff logic, packaging from low MOQ | Stock models only | Fixed SKUs, no private label |
| Price (factory direct) | Tiered factory pricing with volume discounts | Unpredictable markups | Premium brand pricing |
Here is the step-by-step path the order took, with the checkpoints that kept quality on track. A standard charging station OEM project then follows 8 steps:
The notes below are from follow-up calls after the first containers sold through.
A: Pedestals live in the impact zone of vans and carts; the aluminum column with a bollard guard survives hits that crack plastic shells.
A: The full-circumference LED ring shows port state from the vehicle, so nobody walks to a dead port.
A: Through a trench entry in the bolt-down base, keeping the column sealed to IP54.
A: Yes, two metered sockets with independent authorization and billing.
A: Marine-grade coating and sealed entries carry the warranty in salt-air locations.
