7.9x5.5mm Male to Small Square Adapter

This adapter converts a 7.9x5.5mm male power plug to a small square second-generation female interface. It suits laptop owners who need to connect a legacy barrel charger to a newer device port. The 10cm cord keeps the connection short and tidy for travel or desk use.

Practical Limits of the Barrel Interface

The 7.9x5.5mm barrel connector is a passive mechanical fit and does not convert voltage or current. Users must verify that the power supply output matches the laptop's input requirements before connecting. The short 10cm length restricts placement flexibility between the brick and the device.

Polarity and Pin Diameter Compatibility

The adapter works only when the source plug has a 7.9mm outer diameter and a 5.5mm inner pin. A mismatched barrel size will prevent a secure connection or cause intermittent power delivery. Check the original charger tip markings to confirm these exact dimensions.

Questions about this item

Should I choose this 7.9x5.5mm male to small square adapter or a different tip size?

Select this adapter only if your power brick has a 7.9x5.5mm barrel plug and your laptop requires the small square second-generation socket; otherwise choose the tip that matches both ends of your connection.

What does the 10cm length mean once it is in a real machine?

The 10cm cord adds a short bridge between the brick and the laptop, keeping the setup compact for travel while still allowing the connectors to seat fully without strain.

Which interface standard does the small square female end follow and what does it cap in practice?

The small square female end follows the second-generation proprietary socket used on compatible laptops; it passes only the voltage and current that the original power supply and laptop negotiate, with no additional signalling capability.
