Review on 5000MAh S-Miphee Charging Case For IPhone 7 Plus/8 Plus - Battery Charger Case For Extended Power by Alexander Roberson

The seller does not provide the actual size and weight of this case. It is 0.70 thick and weighs 12.3 oz with the phone installed. Thickness feels worse because the battery hump is extended all the way the sides unlike Apple's own case or those of others. It is definitely not slim. The Achilles heel of these cases in my experience is the lighting cord connection loosening to the point it loses contact and can't charge the case. This one felt tight the first time I plugged a cable in but within 24hrs started to loosen up. Battery seems weak with more than half discharged to raise the phone battery from 55% to 82%.
