The numbers that mattered with landed cost at 31% under the branded alternative at the same retail point 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.
Published by Wanlin | Last updated: September 05, 2026 | Expertise: two-wheeler and three-wheeler EV charging station OEM and ODM manufacturing for global markets
Most distributors start with price. This one started with a complaint log. 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, Chhay Sophal selected Wanlin as their EV charging manufacturing partner. The order followed, but only after the buyer verified three things on the bench.
The bike shed had a row of scorched sockets and a handwritten notice telling riders to bring their own timers.
What looked like a price problem turned out to be a reliability problem in disguise. A resort bike fleet lost batteries to a charger that had no reverse-polarity protection when staff plugged leads in a hurry.
Field case: A resort in Phnom Penh issued the WL-AC33 to staff after reverse-polarity leads killed two packs in a hurry. The protection circuit survived repeated wrong-way tests, and the resort bike fleet downtime fell to near zero.
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 comparison table below is based on the buyer's own bench notes, not our marketing claims.
| 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 |
From the first sample request to the sailing date, the buyer could see each gate in writing. A standard charging station OEM project then follows 8 steps:
Different markets, same conclusion, in the words of the buyers themselves.
A: Turn the rotary dial to the pack specification and lock the cover; eight steps run from 6A to 15A.
A: Yes, the protection circuit blocks wrong-way connections, tested repeatedly on the bench.
A: Yes, dedicated multi-stage curves per chemistry, selected at the dial.
A: Yes, the IP54 shell mounts on the wall or travels with the fleet in a pannier.
A: Yes, logo and color runs start from 100 units.
The numbers that mattered By working directly with manufacturer Wanlin, the Electric Tuk-tuk Fleet Operator team in Phnom Penh 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.
