You need AA batteries for e.g. a flashlight, but don't want an extra charger?
This battery is the solution, because it is charged via USB plug which is hidden in the cell head. So the battery can be charged e.g. at a USB power supply, USB car adapter or even at a powerbank. Ideal for on the road or on vacation. The USB port is under the pole cap, which is simply pulled off for charging. A rubber band secures the pole cap from loss.
