My iPhone 5 I can therefore bring about 2 times by 10% to 100%, a GoPro2 can thus be charged about 5 times. For long outdoor days without electricity so wonderful!
But what excites me is this built-in flashlight with pushbutton switch in a prominent place. By pressing because it accidentally (pocket / backpack) then the battery is empty after 4 hours!
Why someone builds there a flashlight?
And wiso gets then no ordinary switch?
