Case Study: Sao Paulo Trading Company Sourcing Manager Sourcing Success
Thomas Bennett, a Trading Company Sourcing Manager based in Sao Paulo, was sourcing two-wheeler charging equipment for a network that had grown faster than its charging points. The distributor had lost two container deals because the factory could not provide OCPP conformance statements before the payment deadline.
After comparing four shortlisted factories, Thomas Bennett 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.
- Capacity control: production slots are confirmed before the order, and pre-shipment inspection photos are shared batch by batch
- Payment compliance: QR, RFID, NFC, coin and App payment modules are selected to match local payment habits and regulations
- OEM / ODM depth: custom enclosure colors, logo silk-screening, voltage ranges (48V / 60V / 72V) and socket counts
After a factory audit and sample evaluation, the partner placed a first order of 30 charging points and expanded twice within the year.
Problem Analysis & Field Report: Why Global Buyers Need Portable Low-Voltage EV Charger
Most charging problems in growing cities are not about the vehicle, they are about the socket: wrong voltage, no protection, no payment record and no maintenance plan. A field service team in Sao Paulo serviced e-bikes across scattered sites, but every depot had a different charger model, so the van carried a box of mismatched adapters.
Field case: A service firm in Sao Paulo standardized on portable low-voltage chargers with interchangeable connectors; the van inventory shrank from nine adapters to one unit per voltage group.
Why it matters for global buyers:
- Portable units bring a controlled charge profile to sites that lack fixed infrastructure
- Low-voltage 48V-72V output matches two-wheeler packs without step-down adapters
- Protection circuits prevent overcharging when riders plug into unknown sockets
- Field teams carry one tested unit instead of a bag of generic chargers

EV Charger OEM Process: From Inquiry to Shipment
A typical Wanlin Fire OEM project begins with the target market, because voltage, certification and payment habits decide the hardware configuration. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - Southeast Asia, South Asia, Africa, Latin America, Middle East or Europe; different markets may require different voltage, certification and payment configurations
- Select a Model Line - our team recommends suitable WL-series models according to your vehicle types (48V / 60V / 72V), site conditions and target customers
- 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
Operators who standardized on one OCPP-compatible line report shorter vendor lists and fewer site visits:
- Andre Silva (EV Charger Distributor, Sao Paulo, Brazil): "We replaced eleven different socket models with one Wanlin line, and our maintenance calls dropped by about 32%."
- Priya Nair (E-Rickshaw Fleet Owner, Mumbai, India): "Our logo, the App name and the payment gateway were all configured before the first container left the factory."
- Thomas Bennett (Trading Company Sourcing Manager, Sao Paulo, Brazil): "Spare mainboards arrived within three weeks when a storm surge damaged two sites, which kept the network online."
Frequently Asked Questions
Q: Can the WL-PT replace the original scooter charger?
A: For 36V to 72V lead-acid and lithium packs, yes - the output voltage must match the pack, and the connector is matched to the vehicle. It is not for automotive EVs.
Q: Is the WL-PT safe to leave plugged in overnight?
A: The charge curve ends in a float stage and the overheat sensor cuts current if the housing exceeds its limit. We still recommend unplugging once the indicator turns green.
Q: Which plugs does the WL-PT ship with?
A: Common two-wheeler charge plugs are stocked. Buyers send their market plug drawing or sample, and we match or mold it - custom molds start at 500 units.
Q: How is the WL-PT packed for retail?
A: One unit per color box with manual and cable, 20 boxes per export carton. Retail-ready packaging with barcodes is available for volume orders.
Q: What is the MOQ for the WL-PT?
A: Standard units start at 100 pieces. Custom-branded retail packaging starts at 500 pieces with a 20 to 25 day lead time.
