20V 6.75A 135W AC Power Adapter Laptop Charger Compatible with Lenovo IdeaPad Y40-70 Y50-70 Y50-70AM-IFI Y70-70 Y700 Z710 Power Cord

I have a Lenovo Yoga 720 that I use everyday for work. For convenience, I wanted a second charger to leave at work, so after looking at the (relatively few) options, I ordered this one. I've been using it daily for a week now, and it works perfectly. It seems to charge at the same rate as my OEM charger, although I haven't performed a formal test of that. The cords are of reasonable length and flexibility (I hate rigid cords!). The block itself is large, as you can see in the photographs. The 3rd photo shows this charger and my OEM charger side by side, and although they're roughly the same length and width, this charger is a good bit taller by about half an inch. Interestingly, it's about the same weight as the OEM charger. But the larger size isn't important to me personally since it's my permanent desk charger (I keep the OEM in my bag for convenience). Overall I'm perfectly satisfied with this charger, and I will update this review if anything should change.

Works great, compared to the stock one that came with my laptop i love the slender design of this plug. Makes it portable & easier to tuck away on the setup at home & at work

Great replacement for Lenovo school computer that my son lost for school.

Quick delivery and price was good. Met my need completely.

This product came as described, it is a bit larger than a regular charger from Lenovo, but gets the job done. 100% would recommend .

Charging ability and quality is great, fits perfectly for my laptop, it doesn't get hot while charging. Highly recommend and good for value.

I ordered one of these chargers a little under a year ago, and it worked fine for about 9 months or so. After those 9 months, I had to put the charger in weird positions to get it to charge my laptop. I decided to order another one, since I have had bad experiences with replacement chargers from Amazon before, and I knew this one would work at least. I pulled it out of the box today and it was charging my laptop just fine for about 10 minutes, and now I can get nothing from it. I am a university student who relies on my laptop, and I live in the city where stores that sell specialty laptop chargers are not very common. This is unacceptable, and I want my money back immediately. I know it is not an issue with my laptop, since it will still charge sometimes after I move the charger around enough, and this is the second charger to not work correctly. I will not be buying any products from this vendor in the future, and I would recommend everyone to look elsewhere for a replacement charger. PLEASE REFUND ME MY MONEY.EDIT: so i played around with the charger a bit, and ive come to the conclusion that the new power bank you just sent me was DOA. Then, i used the old power bank with a different wall cable, neither of the ones you sent me, and now my charger is working. So you sent me a completely DOA piece of crap charger, and a charger with a faulty outlet cord.I still qant my 30 dollars back and I will contact customor support if I am not contacted first.

It's the cheapest power brick of these specs on amazon. The one that came with my laptop was 1/3 of the size but it costs 3x the price on here. I have a large backpack, so it works despite being unwieldy and large. You get what you get for the price.Edit: After a year or so of use, the wire has stripped itself and is now only held together by electrical tape that I applied. Do not transport this with any pressure on the fixed wire (the non-detachable one) or it will do the same for you.
