The Lenovo 00HM613 is a 45 W AC adapter for powering a laptop. It supplies 20 V at 2.25 A and accepts 100–240 V AC at 50–60 Hz, so it can be used with mains supplies in that range.
The black adapter has a straight Slim Tip connector with a center pin. Its specified outer and inner diameters are 11 mm and 3 mm; check these against the laptop’s power connection.
Package contents: one two-pole C7 power cable, as listed by the retailer.
