PortaPow USB Data Blocker - Protect Against Juice Jacking (Transparent, 2)

The PortaPow USB Data Blocker 2 is a useful gadget that provides protection against viruses and hacking when charging devices from unknown USB sockets. It features a transparent casing, allowing users to see that no electronic components are present inside, ensuring the security of the blocker itself. This new version of the blocker offers enhanced security and is made with a more environmentally friendly polycarbonate compound. One of the limitations of the Pure Data Blocker is that it does not have the SmartCharge chip found in the 3rd gen design, which may result in slower charging speeds with certain device and charger combinations. It is also not compatible with extra fast charging technologies such as Qualcomm Quick Charge and Samsung adaptive fast charge, as these require data transfer to be enabled. Additionally, some car USB sockets may not provide enough power to charge a device, requiring the use of a dedicated USB car charger. Customers appreciate the data-blocking functionality of the PortaPow USB Data Blocker 2, as it allows them to protect their devices from data theft while charging. The transparent case makes it easy to see that data connections are indeed severed. Users feel more secure when using public USB outlets in places like coffee shops, airports, and hotels. It is also suitable for those who are concerned about state-sponsored security issues. However, one downside pointed out by customers is that the blocker does not support fast charging. This limitation is mentioned on the product page, as it uses the data pins for functionality. Despite this drawback, customers still find the PortaPow USB Data Blocker 2 to be a great product for travel and for ensuring the safety of their devices.
