Most distributors start with price. This one started with a complaint log. Sell-through data from the region shows the winning listings are the ones with per-port metering and a working payment flow.
After the operator's own four-week load-balance logging test, Grace Tanuwijaya selected Wanlin as their EV charging manufacturing partner. The contract went to the factory that could show RCD trip-time data and sealed enclosures, not the lowest quote.
Standing in the depot, the buyer ran a full 12-port load while the site breaker held and the display cycled port statuses.
It started with one return and grew into a spreadsheet of them. A shopfront owner watched sun-faded QR decals send riders to a dead link after one hot season.
Field case: A shopfront chain in Bandung replaced sun-faded stickers with the WL-QR10 UV-laminated per-port QR decals and tamper-proof covers. Scan success stayed above 99% through the hot season, and the chain added a second station at its flagship corner.
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.
The buyer compared five candidates on the metrics that caused their previous failures.
| 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 |
