Seriously, its a cable, It's 2020, cables are the most basic tech. I put money on all the negative reviews coming from people not using the right portable charger/bank or wall charger. Look at Aukey's 65w and RavPower! They are compact and give you a lot of power, more than the minimum needed for this cable! Min I believe is 15V/3A and both of those do 20V/3.25A!
