seems to work on my x230t, still haven't tested for overheating
After about two weeks of use. Doesn't overheat at first a called bs on the 65W rating let alone 100w , but indeed it does manage to supply the 65w need to function and charge at the same time. The usb port is nice, charges quite well but the usb part does get quite warm after a few minutes , but doesn't seem overly hot. !!!!CAREFULL!!! Be very careful when pulling it out of the cigarette port newer cars can grab the tip so tightly that the socket WILL pull off the contact picture attached. All in all Good, for the price really good, but the case could be better it would be nice if the whole front would be a single peace of plastic.
