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.

Ordered for my lrnovo legion. Said it would work. Spoiler alert. It didnt. Now I have a useless charger and a dead laptop.

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 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.

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.

Somehow our Thinkpad chargers keep being left behind so this one came handy. Works as intended, but is a big brick.

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!

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 have worked from home since the pandemic. Recently, I have had to go into the office to take care of some changes. I brought my laptop but it was such a pain to unplug the power cord and untangle it from behind my desk. One of the times I forgot to pack up my power cord to bring it back home. I live about 45 miles from work. Buying this power supply was a lifesaver. No more crawling under the desk to get a cord.

Got this to be a backup or travel charger and it works great on my Lenovo!
