What this charger replaces

This WAWEIS 20V 8.5A 170W AC charger replaces the original Lenovo ThinkPad adapter for models such as the W540, W550s, E440, E450, E555, L450, S431, S440, S531, S540, T540p, X240, X250 and Ideapad Y720-15IKB. It matches part numbers including ADL170NLC2A, 45N0372, 45N0734, 45N0487, 45N0514, ADL170NLC3A, ADL170NDC3A, ADL170NCC3A and SK90B200850. The unit is supplied new with a 10 Ft power cord.

Who should buy this and who should not

Buyers needing a direct replacement for the listed ThinkPad models will find full voltage and current parity plus FCC, CE and RoHS certification. Over current, over voltage, short circuit and total power protection are built in. Users whose laptops require a different output voltage, a higher wattage rating or a proprietary connector not covered by the compatibility list should look elsewhere.

Installation and common issues

The charger plugs into the laptop’s existing DC jack and the mains lead connects to a standard wall socket — no tools or drivers are required. The 10 Ft cord length allows flexible desk placement. The most frequent issue is purchasing a unit with the wrong tip size for a model not listed above; verifying the part number on the original adapter avoids this problem.
