Review: Neat little thing - Bought as a belt-and-braces protection for a 3D printer I am using with a Pi and Octoprint. I don't think I strictly need it, in fact, but it is nice to know this specific problem can't occur. Well-made, does its job, and it's a lot easier than modifying a cable.
Review: Possibly the most honest product on desertcart - There’s no hype with this, it is exactly what it says it is - and they’ve literally made it transparent to prove it. The price perfectly matches the product spec. Didn’t solve my particular problem but that’s an issue with my equipment. Well done for providing an honest, well-priced product that solves a need without having to resort to high-priced, obfuscated snake-oil ! (Or taping over USB pins 🙂) Top marks 👍🏼

## 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.

### ⭐⭐⭐⭐⭐ Does what it says !
*by C***T on 3 January 2025*

My USB dongle was kept turning on on my EV car; Which I found kept trouble shooting the 12v battery causing it to drain a lot and potentially causing ICCU problems. Plugged this and got power sourced from the power plug and all sorted!
