The TD-300 features five USB 3.0 ports (three at the back and two at the front), two Thunderbolt 3 ports, a Gigabit Ethernet port, an audio in/out port, and an HDMI 2.0 port.
There are a range of Thunderbolt 3 docks on the market now, but Promise Technology's TD-300 includes a good number of ports and an SD card slot, something that we've only seen on OWC's TB3 dock. A Thunderbolt 3 cable and power adapter are also included.
Promise Technology's dock supports two 4K displays or one 5K display and delivers up to 60W of power to charge a MacBook Pro. That's sufficient for the 13-inch MacBook Pro models, but may be inadequate for charging a 15-inch MacBook Pro under a heavy load.
"As part of our mission to offer solutions that are optimized for rich media workflows, we're constantly expanding our portfolio of innovative solutions that harness the latest technology," noted Vijay Char, president, Promise Technology USA. "The addition of a Thunderbolt 3 dock brings a new level of efficiency and flexibility to creative professionals. Laptops can be charged at the fastest speeds possible, images from DSLR cameras are easily transferred, peripherals such as hard drives and monitors can be daisy-chained for increased productivity, 4K video can be sent to multiple displays, and more. The possibilities are truly endless."The TD-300 Thunderbolt 3 Dock can be purchased from the Promise website or from Amazon for $249.
