7.4 x 5.0 mm DC adapter for HP laptops

This adapter converts a 7.4 x 5.0 mm female DC jack to a matching male plug. It is designed for HP laptop owners who need to connect an existing power supply with the same barrel dimensions. The single-piece unit maintains the original connector geometry without changing voltage or polarity.

Same-size barrel conversion only

The adapter accepts a 7.4 x 5.0 mm male tip and presents an identical female socket, so it cannot bridge different tip diameters or pin configurations. Buyers who need to adapt a smaller or larger barrel, or who require a right-angle exit, will need a different converter.

Questions about this item

Will the 7.4 x 5.0 mm connector fit my HP laptop charging port?

Yes, the adapter matches the 7.4 x 5.0 mm barrel size used on many HP laptop power inputs, so it connects directly without modification.

Does the 7.4 x 5.0 mm barrel limit the power my laptop can draw?

The barrel dimensions set the physical fit; the actual current limit depends on the laptop and power supply specifications, not the adapter alone.
