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.
Once the field units logged 5,000 charging sessions, Thanin Srisuk selected Wanlin as their EV charging manufacturing partner. Two factors closed it: the test report matched the samples, and the answers arrived within a day.
The monsoon test bench sprayed the cabinet for an hour and the IP54 gaskets kept the board dry.
A single customer complaint exposed a pattern the team had not connected. An HOA treasurer documented three spreadsheets of hand-read socket meters before giving up on manual billing.
Field case: A developer in Phnom Penh stacked a second WL-RK5 kit on the same feeder after the first five sockets filled within a month. No rewiring was needed, and the amenity became a leasing talking point.
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.
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:
The quotes below come from follow-up calls after the first season of uptime data arrived.
A: The load cap matches the garage feeder headroom in writing, and per-socket kWh logs answer the billing question before it is asked.
A: Yes, a second kit stacks on the same feeder within the cap, with no rewiring.
A: The kit-level RCD and per-socket breakers ship with witnessed trip records that clear insurance reviews.
A: Nobody; per-socket kWh logs export automatically to the HOA spreadsheet or portal.
A: A single-column surface install with included hardware; an electrician bolts it on and sets the load cap.
