Lenovo 90W AC Τροφοδοτικό 2-Pin (45N0198)

The Lenovo 45N0198 is a 90-watt AC power adapter built for ThinkPad laptops that require a round barrel connector. Its 2-pin AC input with C5 cloverleaf socket keeps the adapter slim and travel-friendly, while the 1.8-metre DC cable gives you enough reach to work comfortably away from the wall outlet.

Highlights

• 90 W output with 20 V / 4.5 A for consistent laptop charging
• Round barrel tip (7.9 mm outer, 5.5 mm inner) with centre pin
• Wide 100–240 V input for use in different regions
• DOE Level VI energy efficiency
• Black finish that matches most ThinkPad models

In daily use

This adapter is a straightforward replacement for the original charger on many ThinkPad T, X, R, Z, L, W and Edge series laptops. The cloverleaf AC cable is detachable, so you can swap it for a local power cord when travelling. Built-in protection against over-voltage, over-current, short-circuit and over-temperature helps keep both the adapter and your laptop safe.
