I have the Dell Latitude X1, which has a small power draw. The Kensington web site indicates shows that two adapters are compatible with the X1 -- the 70 watt and the 120 watt. If you click on product details, the 120 watt model lists "most" Dell models. However, the 70 watt model doesn't list any Dells at all.

There is obviously an inconsistency on Dell's website, so I am hoping that someone with experience can weigh in on this. Will the 70 watt model work?

Many thanks in advance.
