If you have an M1-based Mac, Apple says you're limited to just one external monitor. But Anker, which makes power banks, chargers, docks, and other accessories, this week released a dock that it says will boost your M1 Mac's max monitor count to three.

The 4250 Anker 563 USB-C docking station, spotted by MacRumors, connects to a USB-C port on your computer (which doesn't have to be a Mac) and can also charge a laptop at up to 100 W. Of course, you'll also need to plug in the dock's 180 W power adapter. Once connected, the dock adds the following ports to your setup:

• 2x HDMI (version not specified)
• 1x USB-C (3.1 Gen 1): charges devices at up to 30 W
• 1x USB-A (3.1 Gen 1): charges devices at up to 7.5 W
• 2x USB-A (2.0)
• 1x 3.5 mm headphone jack
• 1x Ethernet

You'll need the two HDMI ports and DisplayPort to add three monitors to an M1 MacBook. There are some notable limitations, though.
