Compact and easy to use, it’s a must-have for professionals needing precise USB power management.

Review: Works as advertised. Blocks the power. I use it with an Android Auto external device because the data+power USB port in my car remains active for an extended period after turning off the car. So I added a splice to draw power from another port (that is off when the car is off) and then only allow data in the primary port. Works perfectly.
Review: Fait parti d'un petit montage dans la voiture pour alimenter le boitier Android Auto sans fil. Le boitier est bien alimenté uniquement quand le moteur tourne. (la connexion se rétablissait avec le téléphone quand je sortait pour aller dans le jardin ou que je bricolais dans le garage). Problème résolu, ça fonctionne depuis 15 jours.

## 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 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.

## Questions & Answers

**Q: Is the data wires usb 3 or is there another product for usb3 that does this?**
A: This device does NOT pass the USB 3.x data lines, only the D+/D- used for USB 1 and USB 2.
I do not know of a device which passes USB 3.x data lines only.  Doesn't mean that it doesn't exist, but I have never seen one - ever.

**Q: Would this help on a usb keyboard(aluminum) when I walk around house electrostatic discharge when I touch it kb has to plugged in ?**
A: No, this blocks power output from the USB port. As USB keyboards are powered by this voltage output, they keyboard wouldn't work unless it has an ac adapter, or used batteries to operate. The best use case I have found for these power blockers is to keep the voltage from away from the mainboard in a 3d printer so it is able to fully power off when the power supply is switched off.

*by P***R on 24 May 2024*

I recently started using the PortaPow USB Power Blocker with my micro USB cable for my 3D printer, and I have to say, it's been a game-changer! This little gadget does an excellent job of preventing my printer from pulling too much power from my sonic pad, which could potentially damage it. It stops charging while still allowing data transfer, ensuring that my devices stay safe and sound. Installation was a breeze - I simply plugged it in between my printer and the sonic pad, and it started working right away. Plus, it's super compact, so it doesn't take up much space. Overall, I'm incredibly impressed with the PortaPow USB Power Blocker. It's a simple yet effective solution that gives me peace of mind knowing that my devices are protected. Five stars from me!
