The one-paragraph takeaway For cash-first sites, the WL-CN6 pairs 6 metered sockets with auto-refund logic and a jam-proof acceptor rated for humid corners. 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. What the field test actually measured netting the buyer a 36% 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 inquiry arrived on a Tuesday; by Friday a sample was on a plane. The quiet shift in the category is buyers moving from flat-rate power strips to metered, OCPP-connected stations.
Once the field units logged 5,000 charging sessions, Rizky Pratama selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
At the taxi queue stand, drivers tapped RFID cards while the station logged each session to the cloud.
The complaint did not arrive through the returns portal; it arrived as a repeat-order question. A dormitory operator traced tariff losses to a fixed coin-to-time mapping set before the utility raised night rates.
Field case: A market operator in Penang replaced a mechanical slot board with the WL-CN6 after string tricks ran months of free charging. The anti-string acceptor and per-kWh mapping ended the losses, and the operator held a 36% margin on the first season of honest coin revenue.
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:
The production version carries the same OCPP stack the pilot units earned, so what the buyer validated is what ships.

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 comparison table below is based on the buyer's own bench notes, not our marketing claims.
| 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 |
The workflow below is the same one every Wanlin OEM order follows, from sample to dock. A standard charging station OEM project then follows 8 steps:
Buyers from three countries said the same thing in their own words.
A: The acceptor uses anti-string mechanics plus a tamper log, and the cash box sits behind dual locks in an anti-pry cabinet.
A: Yes, the mapping adjusts in the field without a technician visit, so utility rate changes do not eat the margin.
A: The station refunds automatically before charging starts when a port reports a fault.
A: Single-coin and multi-coin acceptors are configured to the local currency at order time.
A: No, coin operation runs fully standalone with local counters and a tamper log.
What the field test actually measured By working directly with manufacturer Wanlin, the Electric Scooter Fleet Operator team in Penang reached 36% higher margins on its charging line while keeping rider tariffs competitive. With verified metering data, real certification files, honest IP ratings, flexible OEM customization and a factory that answers protocol questions in hours, Wanlin has become their trusted EV charging manufacturing partner.
