The wall charger that came with your phone just doesn’t cut it while traveling these days. In addition to probably being slow as hell, you likely have at least two or three USB-powered devices that you’ll want to charge every night while you sleep.
Luckily, Anker stuffed four USB ports and 40W of power into a tiny travel charger (with folding AC prongs!), and you can get it for $19 today with promo code AAAA2142.
