Multiple supercharger
We’ve recommended Anker superchargers before; they will charge phones and computer devices really fast. Now, even better is a four-slotted Anker 747 supercharger, which can handle three USB-C cords (the emerging universal standard plug) and one classic USB. This is ideal for traveling, particularly for more than one user, with multiple devices (phone, Kindle, watch, laptop). I used to carry a homemade squid with multiple chargers from one outlet, but this fist-size cube is much more compact, simple, and faster. It can charge up to four devices in a jiffy. — KK
