uniAccessories Type-C / Type-A USB 3.0 2-in-1 Card Reader Review
Cool Metallic Design!

The exterior is made of aluminum and features the “uni” logo.
Mr. GadgetIt has a metallic look and is quite cool.
It doesn’t feel cheap at all.


The box design doesn’t feel cheap either, and the main unit was securely protected by cushioning material, which was reassuring.
Connect to a variety of devices with just this one


Connection is available via USB Type-A and USB Type-C.
Ms. GadgetSince most devices have USB Type-A and USB Type-C ports, you can use it with a wide variety of devices!
Mr. GadgetAfter all, even iPhones are starting to feature USB Type-C now!
Additionally, it can read SD cards and microSD cards.
The ability to perform simultaneous read and write operations is a very welcome feature.
Easy connection just by plugging into a USB port


There is no need to additionally install apps or drivers, and you can easily use it just by plugging it into the port.
Just plug it in—not only for PCs, but also for tablets and smartphones!


Furthermore, you can use it not just with PCs, but also with smartphones and tablets without installing drivers or apps.
Ms. GadgetBeing able to use things casually and easily is really important, isn’t it?
Compact and Easy to Carry


The “uniAccessories Type-C/Type-A USB 3.0 2-in-1 Card Reader” is just a little bit larger than an eraser, so it won’t get in your way when carrying it around.
Mr. GadgetIf you’re worried about losing something so small, make good use of the included strap!
Supports Up to 2TB
The “uniAccessories Type-C/Type-A USB 3.0 2-in-1 Card Reader” supports capacities up to 2TB.
Mr. GadgetI somewhat question whether anyone actually uses a 2TB SD card, but well, having a high maximum supported capacity is always a good thing.
Transfer Speeds Are Fine Unless You’re Particular About It
Because the “uniAccessories Type-C/Type-A USB 3.0 2-in-1 Card Reader” supports UHS-I, it allows for data transfer speeds of up to 104MB/s.
Mr. GadgetUnless you are doing heavy-duty work, I don’t think you’ll have any problems.
However, if you use SD cards with much faster transfer speeds, you will need a card reader that supports higher standards to fully utilize that performance, so that is something to keep in mind.
Mr. GadgetSince the vast majority of SD cards sold on Amazon only support up to UHS-I, this card reader is more than enough.
However, there are SD cards with much faster transfer speeds, so if you are particular about SD card transfer speeds, you should consider purchasing a card reader that supports higher-tier standards.
The image below shows the speed measurements of an SD card using this card reader.


Both the read and write speeds are virtually identical to the speeds measured in reviews on other sites, so I believe it is measuring accurately.
Mr. GadgetThe topmost item is the so-called read speed, and it reaches very close to the theoretical value of 104MB/s.
Don’t worry too much about the fact that it doesn’t reach the maximum 104MB/s, as that is simply due to the performance limitations of the SD cards themselves.
Ms. GadgetWhile high-end models are a different story, standard ordinary SD cards don’t reach the maximum 104MB/s in the first place.
Peace of mind with an 18-month warranty

It comes with an 18-month warranty, allowing you to use it with a relatively high degree of peace of mind.
Conclusion
A must-buy if you are not picky about transfer speeds!
The “uniAccessories Type-C/Type-A, USB 3.0 Compatible 2-in-1 Card Reader” is, in my opinion, a recommended card reader as long as you are not particularly fussy about transfer speeds like read and write speeds.
The design is cool, it supports both USB Type-A and Type-C, it is easy to use simply by plugging it into a USB port, and it is compact and easy to carry—the list goes on, but I felt it excels in a variety of ways.
It can bring out the performance of most SD cards, and unless you have niche, heavy-duty use cases—such as shooting 4K video and setting the save destination for those video files directly to an SD card connected via the card reader—this card reader should be more than sufficient for most people at present.
It comes with an 18-month warranty, and compared to other card readers, the price is quite affordable. Therefore, if you are looking for an inexpensive, reliably functioning, and cost-effective card reader, please consider purchasing one.
