What changed for this buyer The WL-WM10 puts 10 breaker-protected sockets on an IP54 steel panel, each metered and fused, with a firmware load group cap and per-socket auto cut-off. 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. The numbers that mattered which left a 30% margin after the first sell-through cycle cleared 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.
Published by Wanlin | Last updated: September 05, 2026 | Expertise: two-wheeler and three-wheeler EV charging station OEM and ODM manufacturing for global markets
A sourcing visit that began with a spreadsheet ended with a field trial. Distributors who bought generic charging boards on price alone spent the season managing burned sockets and billing disputes.
After a 60-day pilot across three condo basements, Viriya Chanthavong selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
Nobody flagged it at the packing station; the market flagged it first. A shop-house owner documented one tripped group breaker killing all ten sockets every laundry evening.
Field case: An apartment block in Chiang Mai fitted the WL-WM10 after swollen battery packs traced back to all-night charging on timer-less boards. Per-socket auto cut-off stopped the cooking, and the building committee recovered a 30% margin by switching the garage from flat fees to per-socket kWh billing.
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 shipping version keeps the same sealed gland plate and the same RCD wiring the field units earned.

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 rows below come from the buyer's own comparison notes, not from our brochure.
| 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:
Different markets, same conclusion, in the words of the buyers themselves.
A: Each socket runs a timer with auto cut-off, so packs stop drawing at the set time or full-charge signal.
A: Yes, the group ceiling is set in firmware to the feeder rating the building actually has.
A: Timer settings sit behind a lockable cover; riders only see socket status and QR.
A: Per socket, with QR payment and kWh logs exported for building management.
A: Yes, the IP54 panel handles shed and column mounting with the included anchor kit.
The numbers that mattered By working directly with manufacturer Wanlin, the Municipal Project Contractor team in Chiang Mai 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.
