Several months ago, accessory company Hyper introduced a set of three USB chargers designed with travel in mind, featuring compact designs based on GaN technology and interchangeable charging heads for convenient international travel. I've spent some time testing out the 70W ($59.99) and 100W ($89.99) versions of the new HyperJuice charger line, and Hyper has more recently added an even more powerful 145W version ($119.99) to the family.
