Car chargers look simple, but a poorly specified car charger OEM order leads to returns, certification failures, and burnt connectors. This guide covers what procurement teams must pin down before production.

1. Output & Charging Protocol

  • Power: 30W–100W PD 3.0 is the current sweet spot; GaN lets you shrink the body.

  • Ports: Dual USB-C or USB-C + USB-A combos remain popular for fleet and taxi use.

  • Vehicle class: Confirm 12V (cars) and 24V (trucks/buses) compatibility.

2. Safety & Certification

Automotive environments are harsh. Require:

  • Over-voltage, over-current, short-circuit, and temperature protection.

  • CE, FCC, RoHS, and (for EV-adjacent use) relevant automotive EMC testing.

  • Flame-retardant housing rated for cabin temperatures.

3. OEM vs ODM

A standard car charger supplier offers OEM (your label on a catalog SKU) at low MOQ. For differentiation, choose ODM with a private mold shell, custom LED ring, and retractable design — typically 3,000+ pcs.

4. Validate Before Mass Production

  • Pre-production samples on a real vehicle electrical system.

  • Thermal imaging under maximum load for 2+ hours.

  • AQL 2.5 incoming inspection on the first three shipments.
