Mona Kattan's Must Haves: From Her Go-To Scent to a Portable Charger

"There are a few things in life that you just have to have: it's data and battery on your phone," Kattan says. She needs to have a portable charger on hand with her busy schedule, and the INIU Portable Charger ($21, originally $25) is her go-to. This power bank is a thin, lightweight device that can fit into small bags (it's a little bigger than a credit card but smaller than an iPhone). It's equipped with three ports, one USB-C and two USB-A ports, so you can charge up to three devices at once. "My phone is almost always 85 percent and above," she says.
