The Anker 523 Charger (Nano 3, 47W) is a compact dual-port USB-C wall charger that fast charges two devices at once, in a body about the size of an old 20W brick.

Two USB-C ports let you charge an iPhone and an iPad together — 27W from one port and 20W from the other. Need more for a single device? Either port delivers up to 45W on its own, enough to charge a MacBook Air at impressive speed. Anker's ActiveShield 2.0 monitors temperature over 3 million times a day for safer charging, all packed into a genuinely travel-sized 47W charger.
