Dell Laptop Power Adapter Converter 7.4×5.0mm to 4.5×3.0mm
This converter tip is a small yet practical accessory designed to adapt older Dell power adapter plugs (7.4×5.0 mm) for use with laptops that require the newer, slimmer 4.5×3.0 mm barrel connector. It allows users to reuse existing higher-power charger bricks, reducing the need to buy a completely new adapter. The compact size makes it easy to carry in a laptop bag or toolbox and install without modifying cables.
Built with durable plastic housing, the converter is lightweight and doesn’t noticeably add bulk. Internally, it’s engineered to maintain stable electrical contact, ensuring the converted connector delivers consistent power with minimal loss. The design ensures the 7.4×5.0 mm end fits securely into the original charger while the 4.5×3.0 mm tip inserts cleanly into the laptop’s power jack.
