It looked like a routine RFQ until the buyer mentioned what the last batch cost them. Two-wheeler registrations climb across the region every quarter, but the charging hardware under bike sheds has barely changed in a decade.
Once the field units logged 5,000 charging sessions, Aung Kyaw Moe selected Wanlin as their EV charging manufacturing partner. By the time the container was booked, the decision had already been validated by real riders.
The monsoon test bench sprayed the cabinet for an hour and the IP54 gaskets kept the board dry.
The complaint did not arrive through the returns portal; it arrived as a repeat-order question. A repair shop bench charged lead-acid and lithium packs on one fixed-current charger and cooked a lithium pack within a week.
Field case: A rental fleet in Johor Bahru deployed the WL-AC33 across its check-in desks after swollen packs appeared on shared chargers. Per-chemistry curves cut battery replacements by a third in one quarter, and the fleet held a 33% margin despite cutting rental rates.
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:
Inside, the board layout keeps the 4G radio away from the contactor coil so sessions stay online when ports switch.

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.
Ranked on what caused the previous supplier to lose the account, the factory scored first on every row that mattered.
| 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:
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.
Measured result By working directly with manufacturer Wanlin, the EV Charging Equipment Wholesaler team in Johor Bahru reached 33% 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.
