Unirex 128GB MicroSD Bundle

This bundle provides a 128GB microSD card together with a USB-C reader and an SD adapter. It is built for users who need portable storage for full HD or 4K video recording and fast file transfers. The card is waterproof, x-ray proof, temperature proof and shockproof. Compatible with most operating systems for broad device support.

Ideal for USB-C phones and multi-device workflows

The included reader moves data between microSD cards and USB-C smartphones, tablets or PCs without extra cables. The SD adapter lets the same card work in cameras, laptops or card slots that only accept full-size SD. Buyers who need higher capacities or faster sustained write speeds should look at other options.

128GB capacity with multi-format support

The single specification that decides fit is the 128GB capacity combined with support for microSD, microSDHC and microSDXC formats. This determines how much footage or how many files the card can hold before offloading. Verify that your host device accepts cards of this capacity and format class.

Questions about this item

How often will the 128GB MicroSD card need replacement under normal use?

The card is built to be waterproof, x-ray proof, temperature proof and shockproof, so it resists the common causes of early failure. With no moving parts and robust construction, it typically lasts for years of regular read/write cycles before wear becomes a concern.

What speed limit appears first during sustained 4K video recording?

The card is rated for smooth full HD or 4K video recording and playback, so the write speed ceiling is the first limit reached during long captures. Sustained high-bitrate streams will hit that maximum throughput before the 128GB capacity fills.

Does the USB reader get hot or draw much power during all-day transfers?

The reader has no active cooling and draws minimal bus power from the host USB or USB Type-C port. It stays cool to the touch during continuous operation because the MicroSD card itself consumes very little energy and the adapter adds negligible overhead.
