Charge from USB-A ports without opening a USB data connection. The Rixmie USB-A Data Blocker sits between a USB-A power source and your existing USB-A charging cable, creating a charge-only connection that blocks USB file transfer and syncing while allowing charging power to pass through. The compact aluminum-alloy housing measures only 1.14 inches (2.9 cm) long and is easy to carry for airports, hotels, libraries, offices, vehicles, and other shared charging locations. It supports up to 60 W power pass-through at 20 V / 3 A max and QC 2.0/3.0 pass-through when used with compatible chargers, cables, and devices. Actual charging power depends on the complete charging setup. This product does not support data transfer, device syncing, audio, video, displays, or USB peripherals. Package includes two black USB-A male-to-female data blockers. This adapter helps reduce unwanted USB data connections but does not guarantee protection against every security threat.
