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

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.

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.

Ive been in a charger bind for a while now, the plastic was wearing away by the port and there were obvious connectivity issues because Id have to jiggle the cord to get a charge. I was avoiding buying a new one because theyre so expensive, I was really glad to find one that was made for my lenovo (but not with the lenovo brand name and price). This works like it should, and no more jiggling. Woohoo!

Charger works as expected with a Lenovo Thinkbook E15

Ive been wanting an extra charging adapter for my Lenovo laptop for a while. I work with my laptop outside of the house at least two days a week and if I manage to forget my charger at home Im basically SOL. My laptop is a gaming laptop and the battery only lasts for about 2 hours, and thats if I have all of the power saving settings maxed out. With a second adapter I can have one that lives at my desk at home and one that lives in my backpack for travel. This adapter had been successfully powering my laptop for the last 24 hours and my laptop had made no complaints so far. This matches the input and output stats of my original charging brick, so this is a winner in my book. *Worth noting that this is not advertised for my 2018 Lenovo Legion laptop, but the plug in the charger fits perfectly and the input and output stats are identical to the original.

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.

This powerful 170w charger is working great for my Lenovo workstation. No issues with warnings that its not working. Charges just as fast as the OEM one. No issues and would purchase again.

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.

I have the power supply that came with my Lenovo P73 laptop, but it is always handy to have a backup or a second location. Saves having to carry your power supply everywhere. Works flawlessly.

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.
