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. ## Frequently Bought Together - PortaPow USB Power Blocker - Stops Charging, Allows Data (Single Pack) - ALINNA Black USB 3.0 Female to Dual USB Male Extra Power Data Y Extension Cable Splitter Adapter for 2.5" Mobile Hard Disk - Anker 323 USB-C Car Charger Adapter, 52.5W Cigarette Lighter Charger with 30W PowerIQ 3.0 Fast Charging Cable for iPhone 15/15 Pro Max, 14/13/12 Series, Galaxy S23/22, Pixel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/359343622-portapow-usb-power-blocker-stops-charging-allows-data-single-pack](https://www.desertcart.pt/products/359343622-portapow-usb-power-blocker-stops-charging-allows-data-single-pack) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-15*
