The USB to 3/4-pin step-up fan power cable can convert the DC5V voltage provided by the USB port into the DC12V voltage used by the computer fan through the boost module. The cable adopts a 1-to-1 design for expanding the connection of a single chassis fan.
Connector 1: USB-A male plug(boost version); Connector 2: 3/4-pin fan male plug; Input: DC5V; Output: DC12V; Cable specification: 24AWG; Applicable current: 1.5A; Cable core: Tin plated copper; Insulation material: PVC; Type of woven mesh sleeve: PET woven mesh sleeve; Cable length: 54cm/21.26 inches (note: including plug length).
The cable conductor is made of tin plated copper, which has good conductivity and strong oxidation resistance. The sheath adopts black high-density PTE braided mesh sheath, which improves the flexibility of the cable and prevents cable bending and breakage.
This cable is widely used in CPU fans, computer hosts, chassis cooling fans, laptops, power banks, etc.
Note:The 3/4-pin fan male plug of the cable is actually a 2-pin plug, compatible with 3/4-pin fan plugs. The cable only supports power supply and does not have PWM temperature control and speed measurement functions.
