Impressive for the size

These power banks are very impressive for the size and the price.  We were very impressed that they charged up so fast and charged our devices up even faster.  The power banks are great for several different types of devices so they are great to have around if you have more than one device.  The fact that they come two to a package is even better.  Now we both have our own.  There is a light that shows when that it is being charged up or when it is fully charged.  They both come wth usb cords.  The power banks are small enough to put in your purse or back pack.  These power banks are bluetooth compatible.  Great for on the go and traveling.
