The one-paragraph takeaway The WL-WM10 puts ten metered sockets on an IP54 steel panel, each metered and fused, with a feeder-matched 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. What the field test actually measured and the landed margin landed at 31% after freight and duties 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 buyer had already shortlisted three factories before this conversation started. Across the market, most charging complaints trace back to unmetered sockets, flat-rate billing and boards with no overload protection.
After a 60-day pilot across three condo basements, Faridah Yusof selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.
At the taxi queue stand, drivers tapped RFID cards while the station logged each session to the cloud.
The failure was intermittent, which made it expensive to ignore. An apartment corridor board with no per-socket timers let batteries cook all night and swelled two packs in a month.
Field case: An apartment block in Jakarta 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 31% 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:
What the pilot units had in common was a single mainboard with per-port metering and a contactor rated for real monsoon humidity.

| Installation | surface mount on shed wall or column with anchor kit |
| Application | Model | How It Helps the User |
|---|---|---|
| Apartment corridor bike parking | WL-WM10 | Per-socket cut-off stops batteries cooking all night |
| Parking garage wall | WL-WM10 | Metered sockets end the garage flat-fee argument |
| Shop house back wall | WL-WM10 | Tenants pay for exact kWh with QR payment |
| Dormitory bike area | WL-WM10 | Firmware timers behind lock covers stop tampering |
| Warehouse staff wall | WL-WM10 | Group load cap keeps the warehouse feeder safe |
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 |
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.
What the field test actually measured By working directly with manufacturer Wanlin, the Electric Tuk-tuk Fleet Operator team in Jakarta reached 31% 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.
