KeyboardMan · Spark Lite Dual Split 8K. Lighter. Cleaner. The Spark Lite Dual Split 8K Cable is a streamlined take on the Spark cable platform — one USB-A host plug splitting to two USB-C ends, both supporting true 8000 Hz polling. CNC-zinc connectors, IP65 sealing, and a complete travel kit in the box. The everyday version of the Spark cable, without the heavy-build extras. Dual 8K 1.6 m IP65 CNC Zinc 3 Colorways Dual split One host. Two devices. Full rate. One USB-A on the host side splits through a metal Y-junction into two USB-C ends. Each end sustains a full 8000 Hz polling rate at the same time — keyboard and mouse receiver each get peak responsiveness, no shared bandwidth. CNC zinc build CNC zinc connectors. Anti-interference. The host plug, Y-junction, and both USB-C ends are CNC-machined zinc — solid in the hand, lock cleanly into ports, and engineered for EMI shielding to keep the 8 kHz polling signal clean across both devices. Stable data delivery — 1 GB transferred in 25 seconds. Sealed for daily use IP65. Splash, dust, desk life. Joints and connector shells are sealed to IP65 — dust-tight and protected against water spray from any angle. The kind of resilience that handles coffee spills, energy-drink rings, and desk-side accidents without complaint. Wipe the USB-C contacts dry before plugging back in for best signal integrity.

Spark Lite Dual Split 8K cable × 1 Themed charm × 1 USB-C extender × 1 Travel case × 1 FAQ Common questions. How is the Lite different from the standard Spark Dual 8K cable? Same dual-8K split architecture. The Lite is lighter on the build extras — 1.6 m length, IP65 (splash) instead of full submersion-rated, 5V/3A power delivery (15 W) instead of the 65 W tier, and braided sheath only. Same CNC zinc connectors, same 8000 Hz polling on both USB-C ends. Will both devices really run at 8000 Hz simultaneously? Yes. Each USB-C end supports full-rate 8000 Hz polling at the same time — keyboard and mouse receiver each get peak responsiveness, no shared bandwidth drop-off. What's the IP65 rating actually mean? Dust-tight (the "6") and protected against water spray from any direction (the "5"). It handles spills, splashes, and rain on a portable setup. For best long-term contact health, wipe the USB-C ends dry before plugging back in if they've been exposed to water. Can I use it for charging? Yes — 5V at 3A delivers 15 W of power, enough to charge phones, peripherals, and most small devices alongside running the 8K data signal. What's the USB-C extender for? If your device's USB-C port is recessed or surrounded by a case that makes a flush plug hard to reach, the extender adds a short flexible run to bridge the gap. Otherwise, plug directly. Which colorway should I pick? Personal aesthetic choice — the three finishes are functionally identical. All three use the same CNC-zinc connector hardware, the same sleeve, and the same internal cable spec.
