Bests & Worsts Reviews from Amazon

The slow charging part is my fault, I should've paid more attention before ordering this. But I saw 36800 mAh and was excited for so much battery. I've already lost a quarter of the charge just charging my iPhone 8 Plus. Doing quick math I'd say roughly 2000 mAh were fed into the battery, so this is likely around 8000-10000 mAh in all actuality. Pretty much false advertising, if you ask me. I would absolutely not recommend.
