These are good strong cables and seem to give faster ER charging than other regular charging cables I have used for my Galaxy S7 phone and Galaxy tablet. As I've read in some reviews, to include the ER fast charge cable you need a 2.4 amp charging adapter which I have. I would buy it again. I also bought 3.3ft cables which I like as they are neither too short nor too long. But I think it depends on where you plugged your charging adapter. I would recommend.
