Hub with External Power Supply 4-Port USB 3.0

Quick answer: This 4-Port USB 3.0 Hub with external power supply lets a classroom lab connect multiple digital sensors to one computer simultaneously, using its own power source to keep high-current peripherals running reliably during data collection. Hub with External Power Supply 4-Port USB 3.0 is priced at approximately ₹3,250 (indicative market benchmark, incl. GST, August 2026).

The Hub with External Power Supply, 4-Port USB 3.0 is designed for labs running several digital sensors or data-collection devices at once from a single computer — a common setup in modern chemistry, biology and physics classrooms using probeware. Because multiple active sensors can draw more current than a computer’s built-in USB ports can reliably supply, this hub uses its own external power source to keep every connected device powered consistently, reducing the risk of dropped connections or corrupted data mid-experiment. USB 3.0 support also allows faster data transfer than older USB standards, which matters when several sensors are streaming readings simultaneously. STEMAids supplies this hub as an accessory to its broader digital sensor and data-logging equipment range.

Frequently Asked Questions

Why does this hub need its own external power supply?

Multiple active sensors drawing power simultaneously can exceed what a computer’s built-in USB ports reliably supply; the external power supply keeps all four ports powered consistently to prevent dropped connections or corrupted data.

Is this hub compatible with all STEMAids sensors?

Compatibility depends on the specific sensor or data-logger’s USB requirements — confirm compatibility with your equipment set with STEMAids before ordering.

What is the benefit of USB 3.0 over older USB standards here?

USB 3.0 supports faster data transfer, which is useful when several sensors are streaming readings to the same computer simultaneously during an experiment.

How many devices can be connected at once?

This hub provides 4 USB 3.0 ports; if more simultaneous devices are needed, confirm with STEMAids whether additional hubs or expanded port options are available.

Are exact power output and current specifications available for tender documentation?

Exact power output and per-port current ratings have not been independently verified for this listing. Institutions preparing tender documents should confirm precise specifications directly with STEMAids before finalising procurement paperwork.

Is STEMAids a registered manufacturer of this product?

Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
