    This adapter worked perfectly on my wife’s Lenovo computer. It was a good price and delivery was excellent. We shop with Amazon as much as possible and are enrolled in PRIME. I get to review a great selection sitting in my recliner. I not only give 5 stars to the Charger. I give 5 stars to Amazon PRIME. If you are not enrolled you should consider PRIME. It will save you much time. When you do need to return an item, Amazon is amazing – better than standing in line at Walmart. Amazon emails a return label. I package the product, drop it off at a UPS store, and before I get home Amazon has reimbursed my credit card.

    Adapter gets way too hot. Doesn’t seem authentic., September 7, 2017

    I ordered this to use as a spare charger to leave at my office for my Lenovo Yoga 710-15IKB. The charger pin did fit my Yoga 710, however the adapter gets way too hot – so hot that it is uncomfortable to handle. I let it do a full charge on my machine before I realized the heat issue. After realizing the heat issue, I tried charging with it two more times, plugging into two different electrical outlets to ensure that it wasn’t a problem with the outlet. Both times had the same results – the adapter became too hot to handle within just 10-15 minutes of being plugged in. Also, it did not seem to provide a true full charge the first I used it. The battery said fully charged, but within about 15 minutes of unplugging the machine from the charger, the battery percentage began to drop rapidly and the machine was nearly dead about 80 minutes later. (This is a fairly new machine with a good battery, and this has not happened since using my OEM charger.)

    Perhaps I received a lemon. However, I am concerned that the charger I received is not authentic, despite the Lenovo logo being engraved in the plastic adapter. The actual manufacturer label is missing the Lenovo logo on the side of the adapter – kind of a big red flag. Also, the velcro cord tie is “off” in quality and style from the OEM chargers … it’s wider and really long, to the point I have to wrap it 6 or 7 times around the cord bundle to tie it up. It’s made of a stiffer plastic, all fuzzy down one side and plastic velcro “hooks” all the way down the other side. On my authentic Lenovo chargers, the velcro is narrower in width, just long enough to wrap 3x around the cord bundle, made of much more flexible plastic (almost like a nylon ribbon), and one side is fuzzy all the way down with the other side is mostly smooth except for the last half inch or so at the end where the velcro hook material is located. Along with the missing logo on the manufacturer’s label, the significant difference in the velcro quality AND the lack of any Lenovo documentation or warranty information in the box and the way the box was sealed with a clear sticker rather than Lenovo security tape adds to my suspicion that this is a knock off and not authentic. Unfortunately I already tossed the box for this charger before realizing the heat issue, so can’t return it. After experiencing the heat issue, I went ahead and ordered another authentic charger direct from Lenovo. It was over twice the price, but totally worth the peace of mind to get an authentic charger. If you buy from this seller (the charger I received came from a company called Laptop Power, LLC), I suggest inspecting the label on the adapter very carefully upon delivery to ensure that it seems legit, and also keep an eye on it when charging to make sure it isn’t overheating.
