I give this product 5 stars because everything is working exactly as it should and it has my battery problems solved with cellphones final. In addition, you can use this device friends with whom you are traveling very well help if you go out in the battery. The accompanying adapter help this addition, with a fan who Micro USB cable so far have been sufficient for me as Android.
This battery stings in my opinion, especially out by his great power in a small package. The size and shape of the device are very appropriate to the battery always carry in a bag with him. The mAh Power ranges as described from smartphones to charge as follows:
Smartphone with 3000mAh -> 3 1/2 times completely recharge
Smartphone with 2500mAh -> 4 times completely recharge
Smartphone with 2000mAh -> 5 times fully charge
You have the battery thus also quite rare back fully recharge.
A competitor with 5600mAh is slightly smaller in size but has only about half the mAh. And this mAh have felt to about 4000mAh reduced in 1 1/2 years. The RAVPower battery showed in the first 3 months no such phenomena.
Such external battery I would recommend for all who often have the problem that the battery life during the day at 25% comes and you have to worry that the battery soon runs dry. These problems are solved with this product and you can always have the full display intensity activated without any battery-saving modes to activate the smartphone.
The delivery time was very good! 1-2 days and the product is there.
