I use a Nexus 5, which is somewhat famous for its autonomy smartphone. So we decided to make me a gift by offering me this external battery. What a good idea! However, I am not at all convinced. A friend had made me test an external battery and it was awesome! Copy charge rate, I was really attracted by this type of product. This battery has a "power" theoretical 2600 mAh, after I understood that the values are lower réelement (Number indicates a deviation of 18% is one of the best recorded to date so imagine a gap of 20 or 30% of low capacity like here!) With this, it's really cold shower, I explain: - Using reasonably my smartphone while it is charging, the battery continues to discharge, certainly slower but still! A charger that does not charge obviously, look for the error! - Leaving the smartphone without using a charger for about 30 minutes the gain is less than 10%.
For my part, I have not been satisfied, the product is ineffective or almost useless, go your way, There are of much better quality.
