10-pack DC adapter tip for laptop chargers

This set supplies ten 7.4x5.0mm female to 4.5x3.0mm male converter cables. Repair shops and DIY users can adapt existing laptop power bricks to fit devices with the smaller DC jack without purchasing new chargers.

Plug-and-play limits of the DC barrel interface

The adapter only changes the physical tip size; it does not alter voltage, current capacity or polarity. Users must verify that the power supply output matches the device requirements exactly, as a mismatch can damage equipment.

7.4x5.0mm to 4.5x3.0mm tip conversion

This specific dimensional change determines compatibility. The cable works solely when the source charger has a 7.4x5.0mm plug and the target device accepts a 4.5x3.0mm jack with identical polarity.

Questions about this item

How many adapter tips are included in one pack?

Each pack contains 10 pieces, giving you a bulk supply for multiple repair jobs or spare-part storage.

What does the 7.4×5.0 mm to 4.5×3.0 mm conversion actually do for my charger?

It lets you plug a charger that has a 7.4 mm outer / 5.0 mm inner barrel into a laptop that needs a 4.5 mm outer / 3.0 mm inner jack, so you can reuse the existing power supply.

Does the DC barrel interface carry any data or signalling, or is it power only?

The barrel connector is purely for DC power delivery; it does not transmit data or control signals.
