C356 Type-C MicroSD Card Reader with USB 3.0 Super Speed Technology, Supports MicroSDXC, MicroSDHC, and MicroSD for Window, Mac OS X and Andriod (Midnight Grey)

I bought the SmartQ USB-C MicroSD card reader (or OTG adapter) as I was wanting to access some files on a microSD card that I was using as expandable memory for my windows laptop from my Android tablet. The first thing I noticed was that the card reader has a robust build, with a sleek design. Included in the package is a card from SmartQ asking for feedback and offering contact details for if you have any issues. The adapter has a slot for a microSD card on one side and on the other side is a standard USB Type-C connector. You just plug your microSD card into the one side and then slide the USB-C connector into the USB-C port of your device. It slots in easily. I was using a Samsung Galaxy Tab A9+ which worked great. It also worked on my Samsung Galaxy S24 Ultra mobile phone. Once you've slotted the adapter into the USB-C port, your device should inform you that you've got a new USB device connected and then you can go into your device's file explorer and the microSD will show up as external USB storage. You can then access the folders and files on the microSD card just like you can with any internal memory. I was able to view and copy photos and videos from my microSD card with no issues. It works well. I'm was quite impressed. And then, when you're done, you just unplug the adaptor and you good to go. I would say that this microSD USB-C adapter is perfect for using with laptops, phones and tablets that have a USB-C port.

Works perfectly. Tried with my Samsung Galaxy S24 and iPad Air M2. Wanted to view my action camera footage on a recent trip and it allowed me to do so quickly. I always forget to set the date & time with battery changes (so annoying), so after every day I could quickly use my iPad to group that day's vids into a folder. Less than 5mins. Transfers were quick and no stalling or anything. And I love how compact yet sturdy it is. Would recommend! Definitely a bargain.

I picked up the SmartQ USB-C OTG adapter hoping for modest gains, but it blew my expectations out of the water! This compact dongle is solidly built, with precise connector tolerances and snug fit—no wiggle or dropouts. When I plugged in my trusty A2 microSD card and ran the same 573 MB test folder, I clocked ~95 MB/s write and an astonishing 350 MB/s read. That level of throughput rivals many full-size card readers I’ve used. Beyond raw speed, I appreciated the SmartQ adapter’s thermal performance: after multiple transfers it barely warmed up, even under sustained high load. There’s no flex in the port, and it handles both UASP and bulk-only devices flawlessly. It auto-recognized the card every time on Android 15 (and my little Nokia test phone too), making it universally plug-and-play. I haven’t noticed any data errors or hiccups, even on long batch jobs. I paid under £10 for this, which is exceptional value given the performance. The packaging was minimal but secure, arriving without any visible damage to the adapter. If you’re hunting a palm-sized OTG adapter that unlocks the full potential of UHS-II microSD cards, this is it. It’s priced competitively, delivered promptly, and lives up to its advertised specs—something rare in the adapter world. Highly recommended for photographers, videographers, and anyone who needs on-the-go file bursts without compromise. Five stars without hesitation.

Good product but feels a bit flimsy. Great for transferring music from computer to phone and car

First one that arrived was the wrong one, just USB. Returned and refunded straight away. No probs. Re ordered, as other reviewers had no issues. 2nd one was correct and worked a treat. Useful little item. Not noticed any issues with data speeds etc but I'm no techno geek.

Fantastic, exactly what I was looking for, great quality and is actual fast transfer, doesn’t heat up as much but nice a portable so much better vs the usb 2 useless ones that heats up so much and has super slow speeds. This is so worth it, using it for my legion Go micro as scan disk extreme 1TB, works super fast and great quality build and both secure and strong, highly recommended.

Great micro sd card reader

Well made works as it should

This device is make my mmc corrupted.

me encantó, es comodo, y facil de usar con la lap que tengo.

Rempli tout à fait sa fonction. Parfait. Merci.

At first I thought this unit got hot and worked slow. I was using genuine Samsung EVO micro SD cards. They would transfer fast for a few seconds then very slow (below 3MBs) I thought this unit was overheating and reducing speed. Later found out that my Kingston Canvas cards transfer very fast and do not get hot. So if you are seeing slow transfers. Check your cards, not only to see if genuine but also do read write speeds. This little unit works amazing and I get 80MBs with my new setup. Highly recommend this adapter and buying quality mico sd cards.

I absolutely love this little thing. I can’t even begin to tell you how useful it is.. I have a dash cam in my car that uses a microSD card and I have the newer iPhone so it uses a type sheet adapter if I’m ever in an accident all I gotta do is take the car out of the dash cam and boom I have the video on my phone, but I’m a videographer. I use my drones for doing videos. I’m gonna begin my trek all around the world here pretty soon, but this little device even sitting in the middle of nowhere I can put the card and transfer the videos to my phone. Do whatever editing I’m gonna do it. It’s absolutely fantastic.! works every single time do not hesitate. To use it on your iPhone, you simply go to the Files tab on your phone that’s where it likes to store files when you plug it in it’ll show up as another folder on your tab and then you just go through each folder and there’s your photos in your videos it’s great
