Bottom line The WL-TK3 feeds 48V, 60V or 72V DC through multi-stage curves for lead-acid and lithium packs, with heavy-duty sockets and per-port fusing on an IP54 pedestal. 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 which translated into a 38% gross margin on the first container 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.

Most distributors start with price. This one started with a complaint log. Two-wheeler registrations climb across the region every quarter, but the charging hardware under bike sheds has barely changed in a decade.
After the operator's own four-week load-balance logging test, Kumaravel Raj selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
The burned-socket shelf in the maintenance room had shrunk to zero after the old boards were swapped out.
What looked like a price problem turned out to be a reliability problem in disguise. A rank manager measured billing disputes every week because flat-rate overnight fees ignored how empty each battery actually was.
Field case: A rickshaw co-op in Penang standardized on the WL-TK3 after melted plugs on forced connectors. Heavy-duty sockets matched to the pack inlet ended the melting, and the co-op fleet downtime fell by half within a month.
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.
Core Features:
| Parameter | Wanlin Specification |
|---|---|
| Output | 48V or 60V DC matched to tuk-tuk battery packs |

| Housing | IP54 steel pedestal with IK10 rating |
| Billing | per-kWh metering with QR or coin options |
| Display | port status LEDs and kWh counter per socket |
| Installation | pedestal mount with anchor bolts and cable trench entry |
| Application | Model | How It Helps the User |
|---|---|---|
| Tuk-tuk rank charging post | WL-TK3 | Drivers pay per kWh instead of flat overnight fees |
| Rickshaw co-op yard | WL-TK3 | Heavy-duty sockets match the pack inlet without adapters |
| Market loading zone | WL-TK3 | Cargo three-wheelers top up between loads on metered sockets |
| Temple parking area | WL-TK3 | Quiet overnight charging with auto cut-off at full charge |
| School gate stand | WL-TK3 | Parent three-wheelers charge safely behind per-port fuses |
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.
Ranked on what caused the previous supplier to lose the account, the factory scored first on every row that mattered.
| 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 |
Moving from first contact to a sealed container took a sequence the buyer could follow in writing. A standard charging station OEM project then follows 8 steps:
Different markets, same conclusion, in the words of the buyers themselves.
A: 48V, 60V or 72V DC configurations, matched to the pack the fleet actually runs.
A: Yes, multi-stage curves switch by profile so both chemistries charge correctly.
A: Three-wheeler packs draw heavy current for hours; three sockets keep the feeder, fuses and cables inside their ratings.
A: Per-kWh billing through QR wallet, or a coin option for cash ranks.
A: Fire-retardant cable, per-port fuses and an overheat sensor are standard.
Hard numbers from the trial By working directly with manufacturer Wanlin, the EV Charging Station Distributor team in Penang reached 38% 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.
