The inquiry arrived on a Tuesday; by Friday a sample was on a plane. Property developers now pre-wire bike sheds for charging because tenants ask before they sign.
The pilot ran for two full months of monsoon weather, Thanin Srisuk selected Wanlin as their EV charging manufacturing partner. The order followed, but only after the buyer verified three things on the bench.
At the condo gate, a rider scanned the QR, watched the socket lock, and plugged in without touching an attendant.
It started with one return and grew into a spreadsheet of them. A social housing tower banned corridor charging after residents without cards bypassed a keyed socket with tape.
Field case: A rider co-op in Cebu tested the WL-RF8 offline behavior by pulling the network for a weekend. The local authorization list kept every card working and queued the logs, and the co-op ordered stations for two more depots.
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 production version carries the same OCPP stack the pilot units earned, so what the buyer validated is what ships.

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 |
| 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:
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.
