Instead of carrying a phone charger and cable, I now carry an Anker Nano Power Bank. It’s tiny and light (3.5 ounces) and easily powers up my phone in my pocket while I’m walking around at a conference. I travel with two of these in case I have an extra long day and need multiple charges. My one wish for future versions is to have Qi2 wireless charging support to refill these more conveniently when I’m back at my hotel room.
