A:Answer Yes, the second old large "A" size USB jack on Anker products typically supplies standard 5V DC to USB devices. However, based on similar product specifications, the USB-A ports usually provide a power output of 5V/2.4A (max per port), making them compatible with regular USB devices that have been around for many years. If your device adheres to the typical USB power specification of 5V, the USB-A port should work without any issues.
