Case Study: Vientiane Ride-Hailing E-Bike Fleet Buyer Sourcing Success
What started as a request for twenty wall-mounted units from a Ride-Hailing E-Bike Fleet Buyer in Vientiane became a 200-unit pilot after the first OCPP test session. The first quotes he received were for car chargers that needed 380V input, while his depots only had 220V single-phase supply.
Following a three-week sample window, Ahmad Fauzi selected Wanlin Fire as their EV charging equipment manufacturing partner. A factory video walkthrough of the SMT line and aging racks removed the last hesitation about volume capacity.
- Export experience: the factory ships charging equipment to Southeast Asia, South Asia, Africa, Latin America and the Middle East
- Document pack: certificate files, user manuals, installation guides and wiring diagrams are packed with each export order
- Firmware adaptation: OCPP parameters, power limits and time-based profiles configured before shipment
The pilot covered a condo tower, a shophouse row and a market stall cluster in Vientiane, and the failure data pointed to one common cause.
Problem Analysis & Field Report: Why Global Buyers Need QR Code Smart Charging Station
A charging point looks simple until it has to survive humidity, voltage dips, careless riders and an inspector with a checklist. Riders in Vientiane carried three different cards and two Apps to charge in different districts, because every operator used a closed payment system.
Field case: An operator in Vientiane switched a 40-socket pilot to QR billing with time-based pricing; usage reports showed peak loads shifted 33% away from dinner hours within two weeks.
Why it matters for global buyers:
- QR payment works with the wallets riders already use, removing the barrier of a new App or card
- Session records give operators clear revenue data for revenue sharing with site owners
- Time-based or tiered pricing shifts demand away from peak grid hours
- No cash on site means no coin-box theft and fewer maintenance visits
- QR billing ties every session to a rider or vendor account, so operators stop guessing who owes what
- Scan-to-charge removes the need for cards, coins or staff at unattended sites in Vientiane

- Verify Documentation - for certified models, request and verify the relevant certificate, OCPP conformance and enclosure rating documentation files
- Confirm OEM Requirements - color, logo, payment modules, voltage, socket count, packaging and accessories
- Sample Evaluation - samples can be evaluated before mass production according to the agreed commercial terms
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project can proceed to production
- Quality Inspection - chargers are inspected and tested with load-bank and aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials

Frequently Asked Questions
Q: How does the revenue settlement work for the WL-QR?
A: Payments go to the gateway account bound to the station owner. The cloud dashboard records every session, and settlement follows the agreement between the operator and the payment provider - Wanlin does not touch the funds.
Q: What happens if the 4G network drops on the WL-QR?
A: The station keeps charging and logs sessions locally, then syncs to the cloud when the connection returns. Offline mode keeps the QR payment fallback active for up to 72 hours.
Q: Does the WL-QR have fire protection?
A: Each outlet has its own fuse, leakage protector and temperature cut-off. The cabinet alarms on tamper or overheat events and pushes notifications to the management dashboard.
Q: Can the WL-QR be mounted on an existing pole?
A: Yes. The cabinet ships with wall brackets and pole clamps for 60 to 114mm diameter poles, so street-light poles and parking posts can be reused without new civil work.
Q: How are the WL-QR units packed for export?
A: Each station is wrapped, corner-protected and packed one per carton with the mounting kit and manual, four cartons per outer crate for sea freight.
