4.5 x 3.0mm Male to 7.4 x 5.0mm Female Adapter
This adapter connects a 4.5 x 3.0mm male power plug to a 7.4 x 5.0mm female socket on a laptop or notebook. It is intended for users who need to match a power source with a different barrel connector size. The cord measures 20cm in length.
Replaces Mismatched Barrel Connectors
The cable bridges the gap when a charger tip does not fit the device input, avoiding the need for a whole new power supply. It is worth using when the voltage and current ratings of both ends already match and only the physical interface differs. It does not convert voltage or regulate current.
Passive Connection Under Continuous Use
As a passive copper cable, it carries whatever current the connected supply and device negotiate without active components. Heat rise depends on the load drawn by the laptop and the contact resistance at both barrels. The short 20cm run keeps resistance low, but the adapter itself has no thermal protection or current limiting.

Questions about this item
Will the 4.5 x 3.0mm male plug fit my laptop's power port?
The adapter has a 4.5 x 3.0mm male connector. Measure your laptop's DC input to confirm it matches this outer and inner diameter before ordering.
How do I connect the 7.4 x 5.0mm female side to my charger?
Insert your existing charger's 7.4 x 5.0mm male tip fully into the adapter's female socket until it seats firmly, then plug the adapter's male end into the laptop.
Does the 20cm cable length put strain on the laptop port over time?
At 20cm the cord is short, so support the adapter brick or cable near the laptop to avoid sideways leverage on the 4.5 x 3.0mm port during use.
