230 W Slim-Tip Power Adapter

This 230 W AC adapter delivers 20 V at 11.5 A through a slim rectangular connector. It is built as a direct replacement for Lenovo ThinkPad P70, P71, P72 and P73 mobile workstations as well as Legion 7, C7 and S7 gaming laptops. The unit accepts 100 V to 240 V input at 50 Hz to 60 Hz for worldwide use.

Black Plastic Housing With Fixed Cable

The matte black enclosure houses a captive DC cable that ends in the yellow-tipped slim connector used by the listed ThinkPad and Legion models. A standard IEC C5 cloverleaf inlet on the body accepts any compatible mains lead. No detachable tips or voltage selectors are present, so the adapter is ready to plug in once the correct AC cord is attached.

Check Connector Shape And Part Number Before Buying

Verify that your original charger uses the slim rectangular yellow tip shown in the product images; round or USB-C tips will not fit. Match your laptop's part number against the supported list such as ADL230NLC3A, ADL230NDC3A, GX20L29347 or 4X20E75111. This unit does not support devices that require a different connector geometry or a lower 170 W rating.

Questions about this item

What output does the 20 V slim-tip connector deliver in practice?

The adapter provides 20 V at 11.5 A for a total of 230 W, matching the rated output printed on the unit.

What clearance does the slim-tip plug need on the laptop side?

It uses Lenovo's rectangular yellow-tip barrel that fits the standard 20 V slim-tip port found on ThinkPad P50, P70, Legion and Yoga models listed.

How do you connect the adapter so the polarity is correct?

Align the yellow square tip with the laptop's keyed port and push straight in until it seats; the key prevents reverse insertion.
