A single demo station ran at the buyer's depot for a month before the first PO was cut. Across the market, most charging complaints trace back to unmetered sockets, flat-rate billing and boards with no overload protection.
After the operator's own four-week load-balance logging test, Faridah Yusof selected Wanlin as their EV charging manufacturing partner. The buyer admitted the deciding factor was a supplier who answered protocol questions in hours, not weeks.
The monsoon test bench sprayed the cabinet for an hour and the IP54 gaskets kept the board dry.
What looked like a price problem turned out to be a reliability problem in disguise. An apartment corridor board with no per-socket timers let batteries cook all night and swelled two packs in a month.
Field case: A shop-house row in Hai Phong split a tripping group breaker across the WL-WM10 capped load groups. Laundry evenings no longer cut charging, and the owner added a second board for the row delivery riders.
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.

| 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.
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 |
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:
Three buyers who ran the same evaluation shared what they told their purchasing committees.
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 E-Mobility Service Provider team in Hai Phong reached 39% 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.
