The feel of the battery is very valuable by the rubberized surface, the built-in LED light enough to illuminate the road or a dark corner in an emergency. The four blue LEDs for monitoring the state of charge be activated in single pressing the button ... If you press twice in quick succession to activate the LED light, which also works with the rest discharged battery, ie even if the USB ports located already off you have an emergency light.
Can buy only recommend for people are like outdoor road and yet do not compromise on amenities such as a charged smartphone or as in my case a wireless router ;-)
