Satechi's slim aluminium hub expands a single Thunderbolt 4 port into three downstream TB4 ports plus a 10Gbps USB-A, returning up to 60W of charging to the host. The host link supports one 8K@30Hz display or two 4K@60Hz displays, and the downstream ports allow up to six levels of daisy-chaining at 40Gbps. Each downstream Thunderbolt port can also push 15W to phones and tablets.

Notes & Compatibility
Four Thunderbolt 4 ports total: one upstream to the host, three downstream. Requires its own DC barrel power adapter (not modeled). Distinct from the later Slim Hub Pro (100W) model. Satechi rates it for two 4K@60Hz displays, one 8K@30Hz, or a single 6K panel on a Mac, and says a MacBook on a base M1 or M2 chip still drives only one external display: that ceiling belongs to the Mac, not the hub. The host cable in the box is 28 inches, which is no accident. Passive Thunderbolt cables hold 40Gbps only to about 0.8m, so a longer replacement has to be an active Thunderbolt cable. Mains power reaches the adapter over an IEC C5 cloverleaf cord.
