Power Adapter for Laptop Charging

This 20cm cable adapts a 7.4 x 5.0mm male power tip to a 4.5 x 3.0mm female port for laptop charging. It connects an existing power supply with the larger barrel to a device that requires the smaller connector. The short length keeps the link tidy on a desk or in a bag.

Compact Connector for Mobile Use

The adapter needs a compatible power brick with a 7.4 x 5.0mm output and a laptop accepting 4.5 x 3.0mm input. It frees you from sourcing a dedicated charger when only the tip differs. No extra cables or voltage regulation are included in the assembly.

Simple Tip Conversion Only

The bundle contains only the gender-changing cable itself. It changes the physical interface without altering voltage, current or polarity. Buyers who need a complete power supply, voltage step-down or additional tip sizes must source those separately.

Questions about this item

Will the 20 cm length reach the power port on my laptop without strain?

The cable is 20 cm long, designed to bridge the gap between a 4.5 x 3.0 mm female socket and a 7.4 x 5.0 mm male plug.

Does the adapter generate heat during continuous use?

It is a passive connector with no active electronics, so it does not produce measurable heat when powered.

Do I need a charger with a 4.5 x 3.0 mm output tip to use this adapter?

Yes, the female end accepts a 4.5 x 3.0 mm male tip, so your existing power supply must provide that exact connector.
