Use for my chromebook.Worked just like the OEM charging cord. Gets warm while it is charging laptop but cools down after fully charged. Very satisfied.Didn't work, I don't think it is 45 watts, charged the chromebook really slowly then quit working after a couple days.Tried to return, but I have to take it to a UPS store, which is 40 minutes away from my house, one way. Not worth the time or gas to return it. In the trash it goes.I received the charged sooner than expected and i am happy with this charger. it works well and it is what i needed it... i surely will buy from this company again, great job! :)It was very easy to find and a really good product. I will order one more. The price was very reasonable.Works great, would buy again if needed.Worked as expected for my sons chrome bookWorks great and worth it for the price. My son let the dog chew his new one and this may be lighter probably cheaper plastic, but works the same.
