Power adapter for laptop charging

The eForChina DC 5521 to DC 4506 adapter converts a 5.5mm by 2.1mm male barrel plug into a 4.5mm by 0.6mm female socket. It is built for notebook users who need to connect a power supply with a larger tip to a laptop that requires the smaller connector.

Suits owners of mismatched laptop tips

This gender changer works for anyone replacing a lost charger or using a universal supply with the wrong tip size. It will not help buyers who need voltage conversion, a different polarity, or a connector shape outside the two listed barrel dimensions.

Fits between supply and laptop port

The male end plugs into the power brick while the female end accepts the laptop’s own charging cable. Its small, lightweight body adds almost no bulk to a travel kit and requires no extra cables or tools to install.

Questions about this item

What power brick tip must I already have to plug into the DC 5521 male end?

You need a charger with a 5.5 mm outer diameter and 2.1 mm inner diameter tip that includes the centre needle.

Will this adapter let me keep using my existing 4.5 mm × 0.6 mm laptop jack?

Yes, the DC 4506 female side matches a 4.5 mm outer diameter and 0.6 mm inner diameter socket with needle.

How can I confirm the connection is solid after I plug everything in?

The laptop should show its normal charging indicator and power on without intermittent disconnection when the cable is moved.
