I still use a second bag, the same one I used with the Surface Pro, but my main bag is pretty minimalist as far as rollers go (Eagle Creek rolling tote that I do ~3 days out of). That said, my second bag is also pretty tiny, meant for an 11.6" netbook, though it carries my T100TAM, a small 6" x 8" notebook, and all my chargers/headphones/cables/gadgets. I too use a multi-port charger, a 3.4A model that seems to handle both the Asus and my Moto X 2014 with no issue, though the Asus did require me to replace my cheapo retractable cables with better 28+24AWG cables for full speed charging.
