Do any of you chaps use either an external battery or battery case to charge your iPhones from? If so whats the best? I have just tried a case from Amazon, https://www.amazon.co.uk/gp/product/B01HXNDBXY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1, (https://www.amazon.co.uk/gp/product/B01HXNDBXY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1,) total poo. Will not connect with either of the phones, usual Chinglish instructions so going back to Amazon Prime on Monday.
Suggestions Please?
These work well with my Android phone and lipo battery
