Female Connector (Input): 5.5mm (OD) x 2.5mm (ID) DC Socket.
Connector Type: DC Power Male Plug to DC Power Female Socket.
Color-Code: Blue Tip.
Application: Commonly used for modern HP and Dell Ultrabooks, high-end portable electronics, and proprietary industrial equipment.
Is this compatible with my HP or Dell laptop? The 4.5mm x 3.0mm blue tip is the standard size for many modern HP and Dell slim-profile chargers. However, because these devices use the center pin for "smart" charging communication, you must ensure the original power supply you plug into the socket matches the wattage requirements of your laptop.
Does this adapter change the voltage? No, this is a passive adapter. It only converts the physical size of the connector and passes the signal through. Always verify that your power source matches the voltage and amperage requirements of your equipment before use.
How secure is the connection? The adapter is built with high-quality metal contacts and a precision-machined barrel to provide a firm mechanical lock. This ensures stable power delivery and minimizes the risk of accidental disconnection during movement.
