170W ThinkPad AC Charger for Lenovo ThinkPad P50 P51 P52 P53 P70 P71 P73 W540 W541 T540P P15 P17 P15v P15g T15g T15p P1 X1 PA-1171-71 ADL170NLC2A ADL170NDC2A ADL170NDC3A ADL170NLC3A

Works well as a backup/garage power supply for my Lenovo P1. The adapter that came with the laptop was 230W, but this 170W is more than enough for 95% of my computer usage. Construction, materials, fit and finish, wire feel, everything feels very close to the actual Lenovo parts.

Charger works as expected with a Lenovo Thinkbook E15

I dont use my Thinkpad P50 as much since getting a new job with a more powerful/modern laptop, but its still around for some consulting work and occasional use in my workshop. I wanted to have a spare adapter in the workshop for the times I want to use the bigger screen and my software load on this system over there. It does what it says it does, keeps the p50 going with 64GB RAM and an extra SSD, and I have no complaints.

Equivalent to the Lenovo charger recommended for my P15 ThinkPad. Provides me with an extra charger for travel so I dont have to disconnect the one that I use with my port replicator at home. Fits and works just like the Lenovo OEM version.

Works great. Super strong

Does exactly what it is intended to. I use this as a travel charger for my work laptop. This way I can leave one at work. No more forgetting the charger and having my computer die after 3 hours

I bought this as a backup charger for my P50, and it has so far been a great travel charger. Slightly lighter than the stock charger but I wouldnt want it to be too light so Im not complaining. As a backup or replacement, this is a great option.

I do like older Thinkpads and have my T440p in a docking station with a couple monitors. A docking station requires more power than a standard 90 watt power brick. This item does the trick. So nice to see that older Thinkpads are still supported by 3rd party accessory manufacturers.

This AC adapter works well. I have included photos of a Lenovo adapter next to this item, as well as a closeup of the specs written on the block. This adapter is larger in physical size than the Lenovo adapter. It works well with my laptop, and I have not felt any heat from the block while in use.

Got this for convenience. Use my work laptop in office and at home. Wanted to have power supplies ready to go at both locations so I dont have to reach behind my desk every time to plug in. Have a third in my laptop bag for mobile use. They all work great and have no issues.
