About this item

• Go to your orders and start the return
• Select your preferred free shipping option
• Drop off and leave!
• DUAL 4K MONITORS ON AIR AND PRO (M2/M3) — drives 2 external 4K@60Hz displays on M2 and M3 ; M1 are limited to 1 external display (an Apple M1 limitation, not this dock's), while Intel Macs and Windows can run one 8K@60Hz plus a second 4K@60Hz screen.
• WORKS WITH EVERY M, INTEL THROUGH M4 (PLUS WINDOWS AND LINUX) — any M Air or M Pro with a Thunderbolt or USB-C DisplayPort Alt Mode port connects right up for charging, storage, and the full port hub, along with Windows and Linux laptops with the same port type.
• 21 PORTS, EACH ON ITS OWN CHIP — HDMI and DisplayPort video, 2.5Gbps Ethernet, separate SD and microSD slots you can use at the same time, a 3.5mm audio/mic jack, plus 6 USB-A and 1 USB-C port at 10Gbps; independent chips per function mean nothing slows down when several run at once.
• FULL-SPEED CHARGING FOR M AIR AND 14" M PRO — up to 90W through the Thunderbolt 4 uplink covers MacBook Air and 14" M Pro at their normal charging speed (16" M Pro will charge, just not at its full 140W turbo rate) while other ports keep your phone, tablet, or power bank topped up; the box includes the Thunderbolt 4 cable and 150W power.
• 40GBPS THUNDERBOLT SPEED, BUILT FOR VIDEO EDITORS — move 4K/8K footage, Time Machine backups, and Final Cut or Premiere project libraries at full Thunderbolt speed through the dock's USB-C and Thunderbolt ports, so external drives never become your bottleneck.
• 12-MONTH WARRANTY, REAL SUPPORT BEHIND IT — every Smartlinx dock ships with a 12-month warranty and US-based customer support; if a port stops performing, we're the ones who make it right.
