135W 20V 6.75A Square Power Adapter Charger for Lenovo IdeaPad Y700 Y700-15ISK 720-15IKB Y40-70 Y50-70 Y520 Y70-70 Z710,ThinkPad T440P T450P T460P T470P T530 T540 T540P T560 W510 W540 P50 ADL135NDC3A

I was giving a 2017 Lenovo ThinkStation P320 TIny without a power adapter. Purchased this adapter since it has the right voltage and current that it requires. Slapped in 16GB of RAM and 512GB of SSD and everything is running fine with Linux. Hopefully, the adapter would last a while.

Delivery was on time, charger was well packaged and all cables were included. Markings on the charger indicated the correct input and output volts and amps. The new charger is about the same weight and length but it’s around a 3/8” tall than the original. The connector going to the laptop was an exact match and the charging indicator seems happy. So 36 hours in it earns 5 stars. Hope that’s the case 36 months from now.

I have to use my laptop at home and at school, and got tired of packing and unpacking my charger. I keep this one in my bag, and it works wonderfully for my Legion Y520. No complaints at all!

Whenever I asked my kid why they never used their 2018 Lenovo Yoga 730 (15") laptop, the answer was always, "It doesn't work like my old laptop." I thought this was attributed to differences in preference until I tried to use it for a Zoom conference. The battery read 0% when plugged in; when I unplugged it, it went dark immediately.Online forums revealed that there was a batch of bad batteries (we missed the warranty cutoff by two months), but to try replacing the power cord first, just in case. The problem was that there are two different types of connector heads. Mine is the rectangular head and this one matches perfectly. Also, the cord is longer than the original cord, so that's nice.Unfortunately, it did not solve the problem so I had to break down and buy a new battery online and replace it myself. That was actually pretty easy, but I'm glad I tried out the cord first. It's always good to have a spare, especially if you travel. I think I'll take over this laptop until the kid remembers to ask me about it...

Works perfect and I have no complaints.

I first bought this item in August 2019. The product was solidly built, although slightly lighter and bulkier than the OEM cord (Lenovo Y700). However, the cord length is slightly longer which is a huge plus for me.As I use my laptop for work as well, this cord is constantly being plugged and unplugged and moved around. Never had any issues until about a month or two ago when it stopped working (perhaps due to the constant wear and tear). I took it as an isolated incident as these things can happen to electronics, and reached out to the seller to replace the item and it was still well within the 1 year warranty.The seller immediately apologized and, given the nature of the product, shipped me a replacement via express shipping which arrived only 2 days later. Great customer service. Highly recommend. They have found a customer for life.

My Y50-70's laptop charger crapped out on me a couple of days ago. I need the laptop running, so I bit the bullet and ordered this charger with two day shipping.The charger came in on time, which was great. Seems like a good replacement for the OEM one. I didn't compare the original to this one (for obvious reasons). So far, charged the laptop once and I'm happy.I'll edit this review after some time.EDIT 10/21/2019: Charger still working strong. The only thing I'm glad I checked was that this charger is only rated for 100-120V input. In Europe, I was not able to use this charger with a simple outlet adapter (and I didn't want to try, since I'd probably fry my laptop!) I actually had to plug it into a transformer to use it safely. However, since it works fine at home, this doesn't hurt my rating at all, in my opinion; just something to watch out for.EDIT 01/01/2021: Charger still working strong.EDIT 06/25/2022: This thing will probably outlive the laptop.

I only had it for 2 weeks at the most. I went to shut off my laptop and the next day it wouldn't turn on. I thought it was my computer, but when I use a lower wattage charger it was charging just at a lower rate, it wasn't my computer. It was this charger. I wasted my money, now I have to wait for the original to ship.
