Tiny 3-in-1 charger
The inCharge All-in-One charging cable is so small it fits in my wallet (along with a band-aid and one Advil tablet). It has USB-C on one end for plugging into a laptop or battery, and a convertible Lightning/MicroUSB connector on the other side for phones and devices. Magnets in the cable let you snap it on a keyring. — MF
