For 4K 60Hz resolution, your device must support DP 1.4. The Anker PowerExpand is special as it offers an HDMI port that supports 4K 60Hz resolutions, where most are limited to 4K 30Hz. You also get speedy 10Gbps transfer rates through two additional USB-A ports, where many rivals max out at 5Gbps. It offers two USB-C ports-one that supports 85W USB-C Power Delivery, while another supports data transfers up to 10Gbps. The Anker PowerExpand 8-in-1 USB-C Hub is compact and powerful, offering greater specs than some of the other leading options on this list. You can certainly use a charger at lower power, but remember that it will power up slower than when using a higher-wattage charger, and if too low your laptop might run out of juice altogether when maxed out on power-hungry apps and devices. 12in MacBook and MacBook Air charge at 30W the 13in and 14in MacBook Pro at 67W, the 15in MacBook Pro at 87W and the 16in MacBook Pro at 96W.

Lower wattage chargers are fine but will limit the hub’s charging potential.Ĭheck the Power Delivery (PD) charging power each hub or adapter offers connected laptops or iPads. Most don’t ship with a charger, so you’ll need to add your own, and remember that it needs to be a 100W charger to give 85W and above charging if offered by the hub. Look for hubs that offer passthrough charging, so you can charge your laptop even though you are using up one of the laptop’s USB-C ports for the hub itself. Card readers come at different speeds: UHS-I at 104Mbps, and UHS-II at 312Mbps although some are slower at 60Mbps. Other ports to look for include Gigabit Ethernet for faster wired Internet access (without the flakiness of Wi-Fi), and an SD or microSD card reader for adding inexpensive portable storage to your system. To fast-charge an iPhone, you need a minimum of 18W and USB-C, so look for extra USB-C slots, which are more capable than USB-A. If your smartphone is compatible, you can charge your phone up to 80% in just 35 minutes.
