I brought this for my daughter to keep her phone and gadgets charged, she cannot breathe without them apparently. I was very impressed with the finish of the power bank and the speed at which it charged her iPhone even while she was still using it. It arrived 80% charged and the power of the power bank drops so slowly so I believe she would get more than the 5.2 charges it claims. I was so impressed that I have just ordered a second one for my husband and I to share so we don’t have to worry about our phones running down in the event of a power failure or when he goes away with the boys for the weekend. Definitely recommend. Postage was extremely fast too.
