Pls guys i use Samsung galaxy note 3 and yet to see a strong power bank that can comfortably charge the phone, I came across one HP Power bank that is 50,000Mah which I was told it's been sold for 3,500 don't know if it's a real one , its very big even bigger than my phone and also don't know how reliable it could be. I need advice on the best power bank to buy Pls guys.
