PortaPow USB Power Blocker - Stops Charging, Allows Data (Single Pack)(Red)

About this item

• This is NOT a data blocker, see PortaPow's other products if that is what you need
• This is a USB-A male to female adaptor which has the D+, D- and 0V (GND) connected but the 5V disconnected, so power cannot pass through.
• Useful for specialist applications such as 3D Printers and Raspberry Pi where providing power results in undesirable effects
• Note a power blocker is not compatible with smartphones, tablets and many other devices. Please read the reviews to see situations where it does and does not work.
• Supports USB 2.0 Data Transfer.
