This is a pretty cool idea. Simply because rechargeable batteries are very common today and laptops are more common than battery recharger. This USB battery has a flip top which lets you flip the anode to expose an inbuilt usb port which you can plug into any USB port and get the battery recharged. This saves time and also is good since you wouldn’t have to lug the battery charger any more.
Maybe this isn’t as great as it sounds, but it definitely is a great idea. Man! These people know how to combine technologies for the better 
These batteries are available in various sizes (AA, AAA etc.) and voltage ratings (1.5V, 9V etc.).
