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

Great cord and fast shipping.

Works great. Super strong

While my P50 wont report connected wattage (Lenovo Vantage is broken) it no longer complains on boot about charger wattage (as it did with my 135w adapter.) No battery drain while assaulting some photos in Photoshop, so Im assuming this is actually a 170w adapter. Works great.

This replacement AC adapter for Lenovo laptops performed just as well as the original Lenovo AC adapter. Ive had issues with other AC adapters in the past that caused my laptop to make various distracting buzzing noises and caused me to be concerned about possible damage to my laptop. This AC adapter worked perfectly and quietly. The ONLY difference that I can observe was that the original 170W Lenovo AC adapter was a bit thinner and lighter. Im happy with this AC adapter and will continue to use it in my home office setup.

Tried to use this on a Lenovo Thinkpad P52. Using the PC for music production with a USB Focusrite 8i6 going to JBL studio monitors. Bought just as a backup. It seems to work as an adapter, BUT it causes a hum through my exterior speakers, no hum when I use the original adapter, so I’m returning it.

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.

Nice long cord length, no issues with my trusty P50 and mine is the one with the xeon processor and Nvidia graphics, pulls a good amount of power and this adapter seems to work identical to the OEM.

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.

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.
