I bought this charger so I could carry less while traveling. It can easily charge my MacBook Pro, iPhone, Apple Watch, and another USB device at the same time. Compared to Apple's OEM charger, it runs quite a bit cooler, even when it's charging my MacBook and other devices at the same time. The build quality is superb. It feels well designed and expensive in your hand, and the folding plug seems very durable. Even the packaging is elegant, as it comes in a box that's reminiscent of how Apple packages its own products.
