When I use this battery backup for my iphone; every two seconds it loads, it no longer seems permanently lose charge "connection" Electrical. Is the product defective or simply poor, I have no idea. Anyway mine works very badly or it is virtually useless and I do not have the patience or the courage to share a bunch of enamels with the seller or return the item to get one noubeau..pas for that value. So avoid product. Now if the seller wants to do it for me demonstrate his good quamité roduct is up to him to take care
