JSAUX USB 3.0 to Micro B Hard Drive Cable (2-pack, 0.3m + 1m) for external drives and mobile backups
Product description
The essentials
If you’ve got an external hard drive (or a USB 3.0 hub setup) and you keep fighting with the “wrong cable” problem, a proper USB 3.0 A to Micro B lead can make life easier. This JSAUX hard drive cable set is sold as a 2-pack with two lengths (0.3m and 1m), which is handy for real-world setups: one cable for a desk/PC connection, another for a more flexible spot where the drive sits.
On paper, the pitch is simple: USB 3.0 data transfer (up to 5 Gbps), plus support for power charging via the same cable. That makes it more than just a “connect and hope” lead—particularly if you’re backing up photos and files regularly. There’s also a durability angle thanks to nylon braiding, strain relief design, and gold-plated connectors for corrosion resistance and signal clarity.
It’s not perfect for every situation, though. If your device uses a different port type than USB 3.0 A to Micro B, you’ll still need the correct cable format—no amount of build quality will change that.
What you’ll notice in everyday use
The most practical difference with a 2-pack is cable management. A short 0.3m lead can reduce slack around a PC or hub, while the longer 1m cable helps if your external drive ends up on a shelf, under a monitor stand, or a different part of the desk.
In day-to-day use—like copying camera photos from a connected phone/tablet to your computer for a backup—the cable’s “data and power” positioning is meant to reduce friction. You’re not only transferring files, you’re also covering power charging through the connection path (where your device supports it).
There’s also a confidence factor from the construction choices. Nylon braided cable typically feels more robust than basic PVC leads, and the stated strain relief is aimed at the spots that usually fail first when cables get bent or tugged.
Key features that matter (and what to be realistic about)
This set leans on a few specific design points:
- USB 3.0 performance claim: up to 5 Gbps for fast transfer and sync, which is relevant if you’re moving lots of files rather than occasional small documents.
- Power charging support: described as “3A Fast Charger” with “data transfer and power charging 2 in 1”. The exact charging behaviour will still depend on your phone/device and what it’s designed to draw from the USB connection.
- Nylon braided, reinforced build: strong military fibre material, plus strain relief designed to cope with bending and everyday handling.
- Gold-plated, corrosion-resistant connectors: intended to help with signal clarity and reduce interference.
- Premium aluminium housing: mentioned as adding durability to the connector area.
Worth noting: the cable is positioned as a practical accessory for compatibility with listed devices and common external drives, but it can’t magically fix mismatched ports. Double-check that you’re actually looking for USB 3.0 A to Micro B before buying.
Compatibility and what it’s aimed at
The product description calls out a variety of target devices and use cases.
It’s described as compatible with certain Samsung Galaxy models such as S5 and Note 3, plus Note Pro 12.2 and Tab Pro 12.2. It also mentions phone/tablet backup via connecting a Samsung device to a computer.
For storage, the cable is described for use with external hard drives and examples include Toshiba Canvio, Seagate Expansion / FreeAgent, and Western Digital (WD) My Passport and Elements.
If you’re using a USB 3.0 hub or you’re wiring an external drive into a computer setup, this cable set is aimed directly at that “it needs to work reliably” moment.
In the box and cable lengths
You get two cables in one pack: a 1-foot-long cable and a 3.3-foot-long cable. That gives you flexibility without needing to buy multiple single leads—especially if you’re setting up one cable for a permanent desk connection and another for travel or a different workstation.

Is it worth it?
This JSAUX 2-pack tends to make sense if you want one USB 3.0 A to Micro B cable for your computer and another for a more flexible position—while also prioritising a tougher build than basic bargain leads. The nylon braided construction, strain relief focus, and gold-plated connectors are all aimed at reducing the “cable that loosens, bends badly, or gets unreliable over time” problem.
It may not be the best match if you’re not sure about the port type you need, because the cable is specifically shaped around USB 3.0 A to Micro B. Also, if your setup only needs a single short connection, paying for a two-length pack might feel a bit wasteful.
Mini FAQ
Will this work for any external hard drive? It’s described as compatible with specific external drive families (and listed examples). For others, you’ll want to confirm they use a Micro B connection on the drive side.
Is it only for data transfer or also for charging? The description positions it as “data transfer and power charging 2 in 1”, but charging performance depends on the connected device’s support.
Why buy a 2-pack instead of one cable? Two lengths help with desk layout and cable slack. If your drive moves between locations or you set up a permanent home workstation, it’s genuinely convenient.
Does the nylon braided design make a difference? It’s aimed at durability and handling stress points (like strain relief near the ends). It’s not a guarantee against damage, but it’s designed for everyday bending and tugging.
What should I double-check before ordering? Check that you need USB 3.0 A to Micro B, and that your device’s side uses Micro B rather than a different port type.
