What the specs mean for you

Charger to use

45W

For full-speed charging, use a USB-C Power Delivery charger rated 45W or more and a cable rated for at least 60W. A bigger charger is safe: the device only draws what it needs.

USB ports

1

1x USB-C (USB 3.2 Gen 1, 5Gbps)

Data speed

5 Gbps

About 400 MB/s: fine for flash drives, hard drives, keyboards and webcams, and a bottleneck for fast SSDs.

Display output

Samsung DeX or screen

Supports an external display. Check the resolution you need.

Two monitors on a Mac

Mirrored

macOS can’t extend two screens through this kind of hub (MST). Both monitors show the same image on a Mac; Windows can extend them.

Total ports

1

Compact: the essentials for travel or a light setup.

Why people pick it

  • S Pen included in the box
  • Works with any 45W USB PD charger; Samsung lists 20W as the minimum
  • USB 3.2 Gen 1 port at up to 5Gbps for SSDs and hubs, plus microSD up to 2TB
  • Samsung DeX gives a windowed desktop on an external monitor through a USB-C to HDMI adapter
  • Thin 5.3 mm body with a 10,600mAh battery

Know before you buy

  • No charger in the box
  • Charging tops out at 45W, the same as earlier Galaxy Tab S models
  • One USB-C port, so charging and a monitor at the same time need a hub with USB-C PD pass-through
  • Samsung doesn't publish a maximum external display resolution
