Product Overview

The In-Vehicle USB Module is a dual-port charging converter that supplies regulated power to USB devices from a vehicle electrical system. It is integrated into dashboards, seat backs, center consoles, bus interiors, and other vehicle panels used to charge phones, tablets, and onboard accessories.

Core Advantages

8 to 36 V DC Input for 12 V and 24 V Vehicles

The DC input range covers normal operation in passenger cars, trucks, buses, and special vehicles. A single module platform can therefore be used across mixed fleets without developing separate 12 V and 24 V charging units.

Dual Outputs with a Combined Current Limit Below 3 A

OUT1 is rated at 1400 to 1600 mA and OUT2 at 2000 to 2100 mA, while the combined output is limited to below 3 A. In shared-console and seat-back installations, both ports can operate at the same time, with current allocated within the module's total output limit.

Protected Output and 10,000-Cycle Port Retention

Short-circuit, overvoltage, and overtemperature protection shut down or reduce output during abnormal loading. The USB interface has been evaluated through 10,000 insertion cycles, limiting looseness in buses and other installations where ports are used repeatedly throughout the day.

Customization Capabilities

Electrical Output Configuration
Input range, output voltage, current allocation between the two ports, protection thresholds, and thermal derating behavior can be defined around the vehicle power system and connected devices.

Panel and Connection Design
Panel cutout, bezel dimensions, mounting clips, rear connector, cable length, port spacing, and installation direction can be matched to dashboards, seat modules, and console assemblies.

Housing and Marking
Housing color, resin selection, texture, illuminated symbols, printed icons, and brand marks can be integrated into the molded front panel.

Quality Control

Input and Combined-Load Verification
Production samples are operated across the approved AC and DC input ranges with single-port and dual-port loads. Output voltage is checked while both ports are active, and the combined current is confirmed to remain below 3 A.

Short-Circuit and Thermal Recovery
The output is shorted for 30 minutes to confirm automatic shutdown and restart after the short is removed. Thermal protection is also checked to confirm controlled power reduction instead of uncontrolled overheating.

Endurance and Interface Release
Validation includes more than 500 hours of continuous operation and 10,000 USB insertion cycles. Port retention, connector fit, housing assembly, and final charging function are checked before release.
