  • Worldwide voltage input for travel flexibility

90W 20V AC Adapter for ThinkPad

This 90-watt power supply delivers 20 volts at 4.5 amps through a 7.9 by 5.0 millimetre connector. It accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use. The unit includes built-in safeguards against incorrect voltage, short circuit and internal overheating. A power cord is supplied in the box.

Suits owners of compatible ThinkPad models

It suits owners of listed ThinkPad Edge, L, T, X and W series laptops that require a 20 volt 4.5 amp input with this connector size. Buyers whose machines need a different voltage, amperage or tip diameter should look elsewhere. The adapter is not suitable for devices that draw more than 90 watts or use a proprietary connector other than 7.9 by 5.0 millimetres.

90 watt capacity for everyday workloads

The 90 watt output comfortably handles typical office tasks, web browsing and video playback on supported ThinkPad models. It will run out of headroom when the laptop demands sustained peak power beyond 90 watts, such as heavy combined CPU and GPU loads or charging a depleted battery under maximum system load.

Questions about this item

Do I need a specific Lenovo ThinkPad model for the 7.9*5.0mm connector to fit?

The adapter fits the ThinkPad models listed, including Edge E420, E430, E530, E545, Twist S230U, SL510, T400, T430S, T430U, T530, T60, T61, W500, X120E, X131E, X140E, X201, X220, X230, X230i, L330 and L521.

Will this 90W 20V 4.5A adapter run an older ThinkPad T60 that originally used a 65W unit?

Yes. The adapter supplies 20V at up to 4.5A; the laptop draws only the current it needs, so a higher-wattage supply works safely with the T60.

How can I confirm the adapter is delivering 20V 4.5A after I plug it in?

The laptop’s power LED should light and the battery icon must show charging; a multimeter on the 7.9*5.0mm tip will read 20V with no load.
