Need a reliable 30-port industrial USB hub for batch charging, flashing or testing? Sipolar A-812 and Sipolar A-812C are built for high-density USB 2.0 workflows where small chained hubs are not stable enough.
Product Overview
Both models offer 30 USB 2.0 ports, DC 5V/60A EC5 power input, up to 5V/2.1A per port, an independent red power switch and a matte black aluminum housing. The difference is simple: A-812 is USB-A, while A-812C is Type-C.

Why Choose a 30-Port USB Hub?
A single high-power hub reduces cable clutter and avoids the instability of daisy-chained small hubs. It is a practical choice for USB drive mass production, phone farms, IoT firmware flashing, tablet charging, repair workstations and USB sensor expansion.
A-812 vs A-812C: How to Choose
Choose A-812 if your devices use USB-A cables, such as USB drives, older phones, barcode scanners, dongles, keyboards or Micro-USB cable setups.
Choose A-812C if your devices use Type-C cables, such as modern Android phones, newer iPads, Type-C tablets, handheld consoles and phone-farm racks.
Power and Deployment Notes
Use a matching 300W or higher 5V DC power supply for the 5V/60A input. The 2.1A per-port output is a maximum, so leave power headroom for long-term full-load operation.
Both models are USB 2.0 hubs with a theoretical speed of 480 Mbps. For SSDs, industrial cameras or other USB 3.0 high-speed devices, choose a USB 3.0 hub instead.
