Review on Listed Adapter Lenovo ThinkPad Charger by Mark Cannon

* The extra-long cord adds weight on the go, so I use a Lenovo wall cord.* If there's no power connection in the wall outlet, the blue light won't turn off immediately. but SLOW turns off. This means you don't get immediate feedback if the connector comes loose.* There is no UL logo on the power adapter itself, unlike the product name when I ordered it.
