Compact Power Bank, Four Colors

Simple and small. It sits in a bag pocket without adding much bulk. The shell is metal and plastic, and the box measures about 18 by 9.5 by 2.8 centimeters at 300 grams, close to the heft of a bar of soap. It comes in red, white, royal blue, or black, so it can match a phone case or just be picked out easily in a crowded bag. Battery capacity in milliamp-hours and output wattage are not published, so this is best treated as a basic backup charger for topping up a phone rather than a device you'd plan a full workday around. There is no listed fast-charging spec here either. Bring your own cable, since none is stated as included. For anyone who just wants a spare charge in reserve without researching a spec sheet, this covers that plainly.
