Bottom line For brands and utilities, the WL-ODM Series pairs in-house SMT and enclosure lines with per-lot OCPP conformance testing and exclusive firmware licensing. 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 30% 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.

A sourcing visit that began with a spreadsheet ended with a field trial. Sell-through data from the region shows the winning listings are the ones with per-port metering and a working payment flow.
After a 60-day pilot across three condo basements, Le Thi Kim Anh 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.
At the condo gate, a rider scanned the QR, watched the socket lock, and plugged in without touching an attendant.
The failure was intermittent, which made it expensive to ignore. A utility buyer documented an ODM run where enclosure seals on the pilot batch leaked despite passing on samples.
Field case: An importer in Bangkok audited the Wanlin ODM flow after a customs scare with recycled certificate numbers elsewhere. Exclusive tooling, per-SKU test reports and seal-test records closed the audit, and the importer moved three lines over in one season.
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:
What the pilot units had in common was a single mainboard with per-port metering and a contactor rated for real monsoon humidity.

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 |
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:
Buyers from three countries said the same thing in their own words.
A: 50 units on existing enclosure tooling; new molds start at 300 units.
A: Yes, socket type, voltage class and plug heads follow your market standard, verified against drawings you approve.
A: We integrate OCPP 1.6J against your endpoint during development and validate the payment flow on your staging gateway.
A: The buyer owns new molds paid under exclusive agreements; custom firmware is licensed exclusively per contract.
A: 15 days for cosmetic and firmware changes on existing platforms, including your logo.
What the field test actually measured By working directly with manufacturer Wanlin, the Energy Solutions Trading Company Buyer team in Bangkok reached 30% 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.
