OEM Charger - Chargers and Adapters

Arrived in a Levono box, looked exactly like the original that came with the laptop (Flex 14). Worked great, charged the laptop in about 30 minutes (from 70%) and only got slightly warm. It's always a good idea to have a spare and this is the perfect solution.

Pros
  • Stylish and modern design
Cons
  • Nothing

Great price and works!

Of course, the fact that the original Lenovo charger stopped working after less than 18 months is very bad. Best Buy had one for $75, but I checked out Revain (of course!) and found this one for half the price. I checked twice if this would work with my Lenovo Ideapad flex 4 and it worked. So fast shipping and I have a better lighter weight. I am very happy. Just take the time to make sure it works with your particular computer and you should be good to go!

Pros
  • Free for educational purposes
Cons
  • Doubtful

The cable is too short; breaks easily; awkward shape

The reason I'm writing this review is because my charging tip came loose and I had to buy another one. These are 2 pieces of metal with plastic inside and a broken tip. I also hate the cable length; It's too short, so the laptop needs to be within 3 feet or so of an outlet. And the base is an odd square shape that, instead of fitting snugly against the wall, juts out. Therefore, it is not suitable for narrow spaces such as a chair or a desk. It's just a cumbersome shape and awkward to use! I'll

Pros
  • Great for a small home
Cons
  • Empty

I got a good power adapter from Amazon.

Bought for a backup for @home use. Came in a box with a spotty envelope. The product looks like an original Lenovo power adapter. All labels, trim, plastic and print quality - everything is high quality and looks like Lenovo. There are a few differences, but these are due to an overhaul of said power supply. I am very satisfied with the product received. Many Thanks. I don't usually write reviews for most of the products I buy on Amazon, but this one makes me happy. I've included all the images

Pros
  • Good product for the price
Cons
  • Updates

I hate that I had to buy another one. This is actually the third one I've had to buy for a computer that's not very old. I'm not sure what the heck is wrong with Lenovo power cords. . . but they suck like kings. The square fork is a terrible design. The best I can say about it is that it is smaller than what came with the computer. The original had a larger square sticking out of the wall, blocking another plug hole (if you turned it upside down to unlock the other plug, it would eventually…

Pros
  • Absolute Legend
Cons
  • Good but not great

THIS ARTICLE WORKS WHILE IT WORKS, AND THEN IT DON'T WORK!

This item works well until it finally stops. In all my years of experience with laptops, I have never had to repeatedly replace the power cord. This cable is a little over a year old and needs to be replaced. It's made of materials that cause the cord to keep spinning, requiring you to keep untangling it until it suddenly stops working. This problem occurred with the original cable that came with the kit. I need a third now. I bought this power cord in late 2018 and have not had to replace it…

Pros
  • Satisfied so far
Cons
  • Hard to say

Perfect power cord replacement for my 110-15isk laptop

I have a Lenovo 110-15isk laptop. I only use my laptop over the network and never use it over Wi-Fi or wirelessly. I've found that because of this habit, power cords only last about a year before needing to be replaced. I bought this cable for my laptop and it works great. The 45W cable plugs into a standard power outlet. The end of the power cord that plugs into the laptop is a round plug. The cable only seems to last after a year of warranty and will die after around 13-14 months when the…

Pros
  • Excellent design
Cons
  • Functionality

The adapter gets very hot. Doesn't look authentic.

I ordered this as a replacement charger for my Lenovo Yoga 710-15IKB at the office. The charging pin fits my Yoga 710, but the adapter gets pretty hot, so much so that it's uncomfortable to use. I had it fully charged on my car before figuring out the heat issue. After realizing the heat issue, I tried charging it two more times, plugging it into two different outlets to make sure the outlet wasn't the problem. Both times had the same results - the adapter became too hot to use in just 10-15…

Pros
  • Excellent overall performance
Cons
  • Useless features
