USB-C holds the promise of unified chargers for the vast majority of gadgets, including everything from wireless earbuds to laptops, cameras, and beyond. Swapping gallium nitride for silicon promises to shrink them down so they take up less room in a bag. Combine them and you get Anker's Nano II chargers. Available in three sizes — 30, 45, and 65W — they use GaN II technology to pack powerful charging in packages up to 58% smaller than competing options, with foldable prongs on the two more powerful models for added space savings. As a result, you get fast charging without any blocked outlets.
