Taylor Hill's London Packing Guide, From Travel PJs to Weekender Bags

Apple Mophie Powerstation Mini ($40)

"A portable charger is a must have for keeping my devices powered throughout the day. It's essential for navigating the city and capturing all those memorable moments," Hill explains. The Mophie comes in black or blue and is compact, measuring 1 x 1.6 x 3 inches. It doesn't even weigh half a pound, so you'll barely feel it in your bag, and it provides 20W of PD power via its USB-C port as soon as you plug it in. What's that mean? To put it simply, your battery will be at 50 percent in just 30 minutes.
