The HNHTKJ 170W AC adapter is a high-capacity replacement charger built for Lenovo ThinkPad and select Ideapad models that need a 20V 8.5A slim-tip power source.

This compact power supply delivers up to 170 watts through a slim-tip connector designed to match Lenovo ADL170SCC3A-style laptops and compatible docking stations.

How reliable and safe is the power delivery?

Will this adapter fit my docking station or workstation setup?
