I am buying . I found I do not really neeed more than 2 ports on the road really -- even one port is managable and I did manage from just laptop but it's very slow to charge so it got dicey. Two ports are plenty. These 4-5 port things are big and heavy. 9 CAD is really cheap for faster charging in a cube similar size to the super excellent Wonpro Nano. I am ruthlessly cutting weight and yes it does add up.
