When you go with a smaller charger, there's a pretty big chance that there's going to be a lot of compromises. One of the big differences when compared to other compact models is that this version of the Nano charger from Anker has two USB-C ports. So, you can charge up to two devices at once if needed. Furthermore, if you need quick charging or need to charge larger devices like a laptop, this charger can handle it, with up to 47W of charging power. That's going to be for a single port, which should be good enough for most people. If you use both ports, it'll be split: 27W on one port and 21W
