Factory Direct 19.5V 18.4A 358.8W Desktop Power Adapter with Active PFC & Optional DC Connectors | Guangdong QINX

The QXP-PAD-19518400 desktop power adapter delivers 358.8W of regulated DC power at 19.5V and 18.4A. Its high-output design is suitable for electronic systems that require substantial continuous power while maintaining stable voltage delivery. The 219 × 90 × 49mm enclosure provides a practical external power configuration for equipment with limited internal space, while the 1.48kg unit weight reflects its high-power desktop construction.

Because the output power exceeds 200W, this model is configured with Active Power Factor Correction (PFC) to improve input power utilization and reduce harmonic distortion. The 100-240VAC input range supports products intended for international markets and allows the same adapter platform to be considered for different regional deployments.

Guangdong QINX supports OEM and ODM customization for this 358.8W power adapter, including DC output connector selection, cable length, housing color, product labeling, logo application, packaging and other project-specific requirements. This flexibility makes the adapter suitable for equipment manufacturers requiring a high-power external AC/DC solution rather than a standard off-the-shelf configuration.
