Silkland S3641 Thunderbolt 4 Cable

The Silkland S3641 is a 1 FT Thunderbolt 4 cable built for professionals moving large media files between certified hosts and peripherals. Its short length keeps signal integrity high on cluttered desks or inside portable kits.

40 Gbps certified throughput

This cable delivers 40 Gbps data transfer when both connected ends support the same speed, deciding whether a workflow runs at full bandwidth or falls back to a slower link. The integrated E-Marker chip negotiates the correct rate automatically.

240 W power delivery headroom

It carries up to 240 W (48 V / 5 A) and steps down to 180 W, 140 W, 100 W, 60 W, 35 W or 18 W as the device requests, charging a 16 inch laptop to 50 percent in 30 minutes while sustaining peak data rates. The 1 FT limit means it cannot bridge longer desk-to-monitor runs.
