So I have to say the battery is just great, whether in the garden or when I'm traveling by bike is always enough power for my phone have been doing! I can my phone Sony Xperia T 10 times full load it! What I think is good is you can charge it with mini USB and the phone as well, so no need other cables only what comes with! Had bought me one where it is not so went it was pretty annoying, a cable for charging for the big battery and one for the phone to recharge! What is also very well done, the LED lamp on the power battery! I am really very happy with the Accu 15600 Easy! And thanks to Amazon for the very fast delivery of the battery's!
