What this adapter powers

The NShi 230W AC adapter replaces the original charger for Lenovo Legion and ThinkPad laptops that require a 20V 11.5A supply. It fits models including Legion 5, 5 Pro, 7, C7, S7, Y540, Y545, Y720, Y740, Y920 and ThinkPad P73, P72, P71, P70, P53, P52, P51, P50, W540, W541, W550 series.

Thermals noise and power draw

The unit accepts 100-240V 50-60Hz input and delivers a steady 230W output at 20V 11.5A for normal charging and operation. It is built to run quietly and maintain safe temperatures under typical daily loads without exceeding its rated capacity.

The deciding specification

This adapter is not compatible with systems that require a 300W charger; verify your laptop’s original power rating before ordering. Matching the 230W output and the correct connector ensures proper fit and function for the listed Legion and ThinkPad models.

Questions about this item

How do I connect the 230W adapter to my Legion 5 Pro 16ACH6, and what mistake should I avoid?

Plug the barrel connector firmly into the laptop's DC-in jack and the IEC C5 cord into the adapter brick; the common error is trying to use this 230W unit on a model that requires the 300W charger, which will not supply enough power.

What part of this charger will need replacement first under normal use?

The detachable IEC C5 mains lead (the "figure-8" cord) typically frays or loses its retaining clip before the sealed brick or the barrel cable, so keep a spare C5 cord handy.

What is the first limitation I will hit when running a Legion Y740 at full load for hours?

The adapter is rated for 230W continuous output (20V 11.5A); sustained peak loads that exceed this will trigger the laptop to throttle or draw from the battery instead.
