Most distributors start with price. This one started with a complaint log. Importers are consolidating charging SKUs with fewer factories that can document OCPP conformance and IP ratings.
After a 30-day pilot at two sites, Anucha Limwong 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. A social housing tower banned corridor charging after residents without cards bypassed a keyed socket with tape.
Field case: A fleet yard in Chonburi moved from shared punch cards to the WL-RF8 with a 10,000-card local list. Every session tied to a card ID, charging losses stopped the same month, and the 31% margin on fleet contracts held for the first time.
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.
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 |

The eight steps below are the ones every Wanlin export order actually follows. A standard charging station OEM project then follows 8 steps:
The notes below are from follow-up calls after the first containers sold through.
A: A 10,000-card local list runs offline, and lists sync from the CSMS when connected.
A: Cards still authorize from the local list, sessions log to memory and upload on reconnection.
A: Yes, card IDs export in standard formats so operators can run shared or roaming schemes.
A: Yes, daily kWh or session quotas apply per card in the tariff engine.
A: Yes, QR wallet payment runs alongside card access on the same ports.
