Published by Wanlin | Last updated: September 05, 2026 | Expertise: two-wheeler and three-wheeler EV charging station OEM and ODM manufacturing for global markets
A single demo station ran at the buyer's depot for a month before the first PO was cut. Two-wheeler registrations climb across the region every quarter, but the charging hardware under bike sheds has barely changed in a decade.
After a 60-day pilot across three condo basements, Nguyen Hoang Minh selected Wanlin as their EV charging manufacturing partner. The purchasing manager signed after comparing failure modes, not just port counts and prices.
In the back office, the CSMS dashboard showed all 20 ports online with live meter values, three days after installation.
What looked like a price problem turned out to be a reliability problem in disguise. An HOA treasurer documented three spreadsheets of hand-read socket meters before giving up on manual billing.
Field case: A condo in Cebu approved charging only after the WL-RK5 kit-level load cap was matched to the garage feeder real headroom. The committee passed the vote in one meeting, and per-socket kWh logs replaced three spreadsheets, recovering a 36% margin on the amenity fee.
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 station that passed all those field tests is built around a metering and protection core that is now standard across the line.

| Application | Model | How It Helps the User |

| Condo shared garage | WL-RK5 | The kit-level load cap wins the committee vote on real feeder headroom |
| Apartment basement | WL-RK5 | Per-socket kWh logs replace hand-read meter spreadsheets |

| Clinic staff wall | WL-RK5 | Trip records clear the facility insurance review |
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 |
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:
Here is what the people who actually ordered said afterward.
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.
Hard numbers from the trial By working directly with manufacturer Wanlin, the Municipal Project Contractor team in Cebu reached 36% 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.
