I needed a universal cable to charge my Macbook with a third party charger and The Wirecutter recommended this cable. It works great and is great for its price. I've also used it to transfer files from external drives but it's USB 2.0 only and slow compared to USB 3.0 but works fine when you need it. The cable looks pretty sturdy and has survived a month at home in various backpacks and briefcases. Good value for money if you need a charging cable.
