With my Garmin there has always been a problem when connecting to a car that the car rather than just giving power to the device would try to connect. This eliminates that problem. Now with rental cars I've switched to Google Navigation and I like that this isolates power only to your usb device, and that way my phone is safe from a USB Virus attack from a rental car. The peace of mind of being able to plug into any USB JACK and just get power only is priceless. CONS: These are easy to loose either to theft or just putting in a drawer and forgetting which one. Yes I'd buy these again, and just did as didn't want to spend time looking, Also I'd recommend them to friends. bdv Review: Carry them whenever I travel. - They work fine. Did a little test to ensure it's power only by connecting phone to laptop with it - it charged the phone but laptop did not recognize the phone - so works as intended. Glad I purchased. ## Features - Attach between your USB cable and charger to physically block data transfer / syncing.

From the PortaPow website as of 02/03/2020: Our Pure Data Blocker not only protects your devices from viruses and hacking from an unknown USB socket while they are being charged, but also features fully transparent casing and zero electronic components inside so you can be sure the blocker itself is secure. It is also made with a 25% lighter polycarbonate compound to be more environmentally friendly. Simply connect the data blocker in between your charging cable and the USB socket when you need to charge your phone, tablet, satnav or other device and you can be sure that only power and no data is flowing between the two. Limitations – 1) Since the pure data blocker has a zero-chip design principle, it doesn’t have the SmartCharge chip featured in our 3rd Gen design. This means charging speed may be slower with some combinations of device and charger. 2) The blocker is not compatible with extra fast charging technologies such as ‘Qualcomm Quick Charge’ ‘Samsung adaptive fast charge’ as these require data transfer to be enabled. Public USB chargers do not support these standards either so your device will charge as normal. 3) Some car USB sockets do not provide enough power to charge a device, so a dedicated USB car charger must be used. **Q: What is the max power throughput rating of this adapter?** A: I believe that this gadget will handle any power that comes from the power cube/adapter. It is basically an adapter with two wires which allows the current to run through (but no wires for data). It is useful when you use a public usb outlet such as in a coffee shop, airport or the usb outlet found at the base of the lamps in many hotels. If you are in a country where you are concerns about ‘state sponsored’ security issues, place this between your own power adapter and charging cable . One cannot be too paranoid, sometimes. :) **Q: is this the 3rd generation?** A: There is nothing on the device, packaging or instructions that indicates what gen it is. It does read, “For a list of all the improvements or to get in touch visit us at PortalPow.co.uk.” Hope this is helpful. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple and Works no Juice Jacking here ;) bdv *by W***E on February 25, 2025* Pros: I like the price and fact that the red makes these stand out.

Glad I purchased. ### ⭐⭐⭐⭐⭐ Great Tool for Finnicky USB Devices (old Garmins) and Defeating Fast Charge Protocols *by S***N on July 4, 2022* Great for devices that will freak out or change modes when they detect *any* data communication -- the red one has a charge protocol detection chip which is useful when securely charging high-draw modern devices, but useless for diagnostic purposes or legacy devices. This adapter is a fantastic way to use standard mini USB leads with devices running the older GarminOS based on an unknown embedded OS (used as recently as the DriveSmart 50, many still run current maps with a microSD setup). These devices give no choice to simply charge if a data connection is detected and block out the UI in PC Connection mode. Newer Linux-based ones (like DriveSmart 65) now have a prompt and will work as expected with the red adapter in a secure charging scenario, or bare lead for normal use. Since USB-A luckily tops out at 2.4A under most cases, even the red one will charge modern devices at a sane rate, but for devices with low standby draw that can trickle charge at 500mA this is useful to defeat fast charging protocols for debugging or increased battery life. The red one should still be safe even if your device uses Qualcomm BatteryKiller 3.0 because of it visibly having no upstream data pins to the charger required to enable fast-charge combinations that are unacceptable for everyday use. In this context this (clear) one is good if you're paranoid, or it's a rare device where the 5v@2.4A provided by the USB BC 1.2 standard is too much . ## Frequently Bought Together - PortaPow USB-A Data Blocker – Protect Against Juice Jacking (1, Transparent, 1) - PortaPow USB-C to C Data Blocker - Protect Against Juice Jacking - PortaPow USB-A to USB-C Data Blocker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/159033525-portapow-usb-data-blocker-protect-against-juice-jacking-transparent-1](https://www.desertcart.it/products/159033525-portapow-usb-data-blocker-protect-against-juice-jacking-transparent-1) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-08*
