I'm definitly an Anker fan as far as Chargers, Batteries and CarChargers. However I travel frequently and HATE messing with cables.
I've found that the right retractable cable can be one of the most appreciated pieces of your kit, so I'm somewhat surprised Anker doesn't offer a high quality retractable among its charging cables.
It also doesn't seem to be a crowded category such as car chargers. Go find a retractable USB-C to USB-C on Amazon. A month ago there was only one.
If you are interested in exploring this category my favorites currently are:
USB to lightning - Scosche 12R: have replaced every apple cable with this one.
USB-C to USB-C - Retrak charge and sync: the only one I could find on Amazon but it works and beats the hell out of apple's new MacBook cables
What do you think ?
