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 👍🏼 Review: Does what it says ! - 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! ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B094FYL9QT | | Best Sellers Rank | 17,515 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 2,099 in USB Cables | | Brand | PortaPow | | Brand Name | PortaPow | | Colour | Clear | | Compatible Devices | 3D Printer, Raspberry Pi | | Compatible devices | 3D Printer, Raspberry Pi | | Connector Type | USB Type A | | Connector type | USB Type A | | Country of Origin | China | | Customer Reviews | 4.0 out of 5 stars 768 Reviews | | Global Trade Identification Number | 00027829469634 | | Manufacturer | PortaPow | | Manufacturer Part Number | PP_PBC1 | | Model Number | PP_PBC1 | | Number of Items | 1 | | Number of Ports | 2 | | Number of ports | 2 | | Power Plug Type | No Plug | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | 3D Printer, Raspberry Pi | | Specific uses for product | 3D Printer, Raspberry Pi | | UPC | 278294696340 027829469634 | | Unit Count | 1.0 count | ## Product Details - **Brand:** PortaPow - **Colour:** Clear - **Compatible devices:** 3D Printer, Raspberry Pi - **Connector type:** USB Type A - **Specific uses for product:** 3D Printer, Raspberry Pi ## Images ![PortaPow USB Power Blocker - Stops Charging, Allows Data (Single Pack) - Image 1](https://m.media-amazon.com/images/I/51YnuSrATxL.jpg) ![PortaPow USB Power Blocker - Stops Charging, Allows Data (Single Pack) - Image 2](https://m.media-amazon.com/images/I/51FAhda7ziL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Possibly the most honest product on Amazon *by A***Y on 21 May 2023* There’s no hype with this, it is exactly what it says it is - and they’ve literally made it transparent to prove it.
