- 3-Pack Set: You get 3 pieces of USB 5V to 12V 4-pin fan speed adapters — perfect for projects that need multiple fan controllers. Enough for replacement, backup, or multi-fan setups.
- Reliable Build Quality: Crafted from high-grade PE plastic and copper, these adapters deliver stable power output and consistent speed control. Built to last through regular use.
- Easy Plug & Play Operation: No driver or software needed. Just plug the USB end into any power source or computer, connect the 4-pin to your fan, and use the switch and knob to adjust speed instantly.
- Smart 5V to 12V Boosting: The adapter boosts a 5V USB input to a 12V output for standard 4-pin fans. Note: Only two wires are active — perfectly normal, as USB power requires only positive and negative lines.
