65 W AC adapter for ThinkPad notebooks

This 65 W power adapter delivers 20 V at 3.25 A through a 7.9 x 5.5 mm barrel tip. It is built for ThinkPad notebooks that require this exact voltage and connector size. The unit accepts AC input from 100 to 240 V at 50 to 60 Hz.

Input range and output limits

The adapter operates on a worldwide input range of 100 to 240 V at 50 to 60 Hz with a rated draw of 1.5 to 0.9 A. Output is fixed at 20 V and 3.25 A for a maximum of 65 W. It cannot supply higher current or different voltages, so it will not charge devices that need more power or a different tip.

Plug-in replacement with fixed tip

Installation is a direct plug-in: connect the AC cord, then insert the 7.9 x 5.5 mm tip into the notebook power jack. The tip is not interchangeable, so the adapter will not fit models that use a different connector diameter or pin layout. No drivers or configuration are required.
