Can a 20V, 4.5A cantravel adapter replace a 19V, 3.42A charger on ThinkPad T440 Lenovo?

I have a ThinkPad T440 that came with the new adaptoradapter plug "slim-fit". The original ACcharger is 19V, 3.42A. I orderordered a replacement AC for travel, and Lenovo sent to me a ACcharger that is 20V, 4.5A, with the same polarity. I read here and there that is OK to use it, but I reallyI'd want to make sureensure that it is 110%totally safe tothe use it. Thisthe new Thinkpads are getting confusing to realizeone with higher voltage and current rating. From what ACI have read on various forums, they say it is OK to use the rightnew one for a exactly model. I will appreciate any helpIs it safe to go ahead and hit. Thanks A lot, Cheers from Brazilstart using the 20V, AM4.5A one?
