SLE-TECH 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.

This product came as described, it is a bit larger than a regular charger from Lenovo, but gets the job done. 100% would recommend. Update: it’s been a year and the charger has held up absolutely perfectly, don’t wait to buy!

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

Excellent, I've had a great experience with the product. Highly recommended.

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

This is not authentic Levono, it's a 3rd-party charger. But it works exactly right in my Levono X1 Carbon; fits and charges, and what more can you ask for? Well, I could ask for 1 thing more ... the cord portion after the transformer is a bit shorter than a real Levono one, to the point of not really letting you put the laptop on a table with the transformer on the floor. But still, worth what I paid for it.

My son got a new position as an Environmental Scientist and needed a laptop. He does not have the money for the laptop he wants yet (maybe in 6 months), so he pulled out his Lenovo from when he graduated college in 2014. He could not find the charger.... I order this charger for him and it worked! He re-image his old (but very good) laptop and was able to work from home. Worth every penny!!!

Original review: It worked perfectly fine for a few months, but then the connection became loose and now it will only charge in very particular positions and will stop charging with the slightest nudge. This is the exact same problem I had with my old laptop charger, hence buying this in the first place! Would not recommend!!!! Updated review: Apparently I forgot that I'd gotten and negatively reviewed this charger before, and bought it twice more. One of the times I bought it, it lasted a full year before breaking, so I trusted it to buy again. However this time it started getting overwhelmed by computer games after about an hour, and then would start cycling from charging to not-charging every 1-2 seconds, causing my computer to freak out and drain battery (albeit more slowly than if not plugged in). It seems that sometimes this charger lasts a long time, but often it breaks after only a few months... so, once again, DO NOT BUY IT!
