Ultra Slim High Capacity 50000mAh Dual USB Ports Portable External Power Bank Charger for iPhone 6 6s Plus 5s 5se Samsung Galaxy S7 S6 S5 HTC (Gold)

Does not hold the charge it says and even though it has energy it stopped charging my phone at 40 percent and that is not okay. The battery stopped working shortly after. Waste of money a star is too generous

I can charge my iPhone twice so it doesn't work

Definitely not 50000mah only lasted for about 1½ charges for my Galaxy S6 edge plus. My old portable charger which was 20000mah lasted 3-4 times longer than this. Maybe it is supposed to be 5000mah? That would make a lot more sense.
