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

Key features

• 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 the 3D Printers and Raspberry Pi where providing power results in undesirable effects
• Note that blocking charge/power will also prevent data transfer for smartphones, tablets and many other devices, so this device will not be useful in those cases.
• Supports USB 2.0 Data Transfer.
