Anker 715 Nano II 65W Charger

A single-port 65W gallium nitride charger roughly a third the size of the plastic brick a laptop ships with. Gallium nitride runs cooler than silicon, which is what allows the shrink. 65W charges most 13- and 14-inch laptops at full speed and any phone or tablet. Only one port, so it charges one device at a time. The single best upgrade to a travel bag for the money.
