Under a thousand: A power bank with some wireless charging speed up its sleeve
The power bank is about 12 mm long and weighs around 270 grams. It is a little heavier than a smartphone, but is small enough to be easily carried inside a jacket pocket, and will not take up too much space even inside a bag. You get a magnetic ring in the box as well as a rather short, 6-inch USB Type-C to Type-C cable.
