What changed for this buyer For scattered and island sites, the WL-4G5 pairs 5 metered sockets with global-band global-band connectivity and remote diagnostics. 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 data showed with resale margins holding at 38% across the first season 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 request that opened the account was a fault report, not a purchase order. The margin squeeze in the category pushes buyers toward factory-direct programs with type-test evidence.
Once the field units logged 5,000 charging sessions, Somchai Prasert selected Wanlin as their EV charging manufacturing partner. The contract went to the factory that could show RCD trip-time data and sealed enclosures, not the lowest quote.
The bike shed had a row of scorched sockets and a handwritten notice telling riders to bring their own timers.
Nobody flagged it at the packing station; the market flagged it first. A pilot program burned weeks of data because chargers polled every minute on a plan billed by volume.
Field case: A chain operator in Can Tho deployed the WL-4G5 across 40 scattered street sites. Push alerts replaced truck rolls, fault response fell from days to hours, and the operator held a 38% margin on site operations for the first time.
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.
Against the three suppliers shortlisted, the deciding rows were reliability data and response speed.
| 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 |
From the first sample request to the sailing date, the buyer could see each gate in writing. A standard charging station OEM project then follows 8 steps:
Different markets, same conclusion, in the words of the buyers themselves.
A: Global band coverage with regional carrier lists, and dual-SIM failover for weak coverage areas.
A: Offline, fault, overload and payment anomalies push to the dashboard and email.
A: Yes, OCPP 1.6J remote start, diagnostics and MeterValues run over your platform.
A: Polling intervals and MeterValues frequency are configurable to fit local data plans.
A: Yes, the dashboard groups units by site with per-port status and bulk firmware updates.
