Power Delivery Limits

Output is fixed at 20V and 8.5A for 170W maximum. The adapter does not replace Lenovo 230W chargers, so systems requiring higher wattage will not charge correctly. Input accepts 100-240V at 50-60Hz for worldwide use.

The DC plug must match the laptop’s centre-positive barrel connector. Verify the tip dimensions against the original adapter before purchase to ensure a secure connection.

Questions about this item

Should I choose the 170W 20V 8.5A model or the 135W version listed as compatible?

Pick the 170W 20V 8.5A adapter; it matches the original 170W unit and delivers the full 170 watts your Legion needs, while the 135W unit would limit power.

What does the 170W rating actually provide when the adapter is plugged into my Legion laptop?

The 170W output at 20V and 8.5A supplies the full power budget for CPU and GPU under load, preventing throttling that can occur with a lower-wattage brick.

The barrel connector looks like the standard Lenovo tip — does it support the 230W protocol as well?

No; the adapter is specified to replace 135W and 170W Lenovo chargers only and does not support the 230W protocol used on higher-power Legion models.
