Anker’s PowerPort Speed 1 is basically Anker’s take on Apple’s 29W USB-C charger that comes bundled with the 12" MacBook. They’re both small bricks with a single USB-C port, power throughput is almost identical (the Anker ekes out one extra watt), and they’ll both charge that 12" MacBook at full speed, or your Nintendo Switch when it’s in portable mode. And if you own an iPhone 8 or are planning to buy an iPhone X, it’ll also give those the fastest possible charging speeds, if you pony up for a USB-C to Lightning cable).
You probably see where I’m going with this, but there is one big difference: Price! The Apple charger will set you back $49, while the Anker is on sale for just $22, down from it usual $26.
