This handy adapter cable will convert a 7.4mm power supply commonly used with Dell, HP and ASUS laptops and docking stations to a 2.5mm male barrel connector.
Laptop power supplies are terrific for powering experimenter projects as they can reliably deliver higher currents in a convenient power cube. The power cubes can also be used for powering LED projects.
The adapter cable measures 50mm (approximately 2inches) end to end and accepts standard Dell, HP or ASUS power adapter plugs. Output is to a 2.5mm male barrel jack.
If your power requirements are for a 2.1mm male barrel jack, see our optional 2.5mm to 2.1mm Adapter.
