Great product, small and versatile., 27 Feb. 2014
About the same size as an iPhone so fits in my pocket and extends my HTC WD7 to allow use for the whole time of any European flight. Led indicators give good status on battery remaining. I can now run GEO tracking apps all day without fear of a flat battery. The built in micro USB is convenient but the additional standard USB means I can also use it on iPhone or iPad. Delivery was next day although 3-5 days was quoted. Very happy.
