Import Dell Laptop Adapter For Pa-12 19.5v 3.34a — Buy in Bulk from Supplier in China

The Dell Laptop Adapter for PA-12 delivers 19.5 volts at 3.34 amps, matching the exact output required by compatible Dell models such as the Latitude E6430, E6440, and Inspiron 15 3000 series. The DC connector measures 7.4 mm outer diameter by 5.0 mm inner diameter with a center pin, ensuring precise fit for the intended devices. This adapter accepts input from 110 to 220 volts at 50 to 60 Hz, allowing use across global power grids without requiring a voltage converter.

The internal circuitry includes over-current and over-voltage protection, which are standard in industrial-grade power supplies for consumer electronics. The housing is constructed from flame-retardant ABS plastic, a common material for adapters operating in ambient temperatures up to 40°C. The cable length is typically 1.5 meters, consistent with industry norms for portable laptop power units. No internal transformer is present; the conversion occurs via a switching power supply design, which improves efficiency and reduces heat buildup compared to linear designs.

This adapter is primarily purchased by IT procurement teams, educational institutions, and resellers who replace failed power units in bulk. It is commonly used in corporate fleets, computer labs, and remote work setups where consistent power delivery is critical. Trade terms include FOB Shenzhen and CIF ports, with packaging in polyethylene sleeves and retail cartons of 50 units. Minimum order quantities are flexible but typically start at 100 units for direct factory orders.
