UGREEN SD Card Reader, USB C USB 3.0 Micro SD Card Reader Memory Card Reader Adapter for SD SDHC SDXC MicroSD Compatible with iPhone 16 15 Pro/Pro Max Samsung Android Computer PC MacBook iPad

These guys seem to only make good stuff, which is why I bought this. I'm using it to access micro sd cards on my galaxy s24 and it works perfectly with micro usb to usb c. So far I've used it to review dash cam footage, perfectly sized to keep in your car where it won't take up much space but not small enough that you're going to easily lose it.

This adapter is awesome — it works with PC, iPhone, iPad, and any device with USB-C or USB. It’s very fast, much cheaper than other brands, and smaller too. The only thing to note is that on a MacBook Air, when it’s plugged in, you can’t use the USB-C port next to it. But I usually use a hub for my display, so it’s not an issue. I also use it to transfer photos from my camera when we travel — super handy.

Bought this to transfer my games and such on an anbernic device I purchased and this works amazing. I’ve heard such good things about this brand and finally bit the bullet. Works perfect no problems and is double sided which is super nice. It’s a good price and moved files at a good speed I’d say, I didn’t check but I was transferring GB’s of files.

Let me start with an emphatic good feeling about U Green - I have many U Green cables and adapters and this is the first time I’ve had any issues.I got this because I wanted to load an image from a micro SD card into a Yamaha mixer. That has a standard USB A slot, but is particular about formats etc. Still, my colleague had no trouble mounting the card with his adapter, so I assumed I would be able to also. Plus, this has regular SD capability and USB C which is a bonus.No good. I tried several different things and they just wouldn’t Mount. Then, to make sure nothing was wrong with the cards or formats of the contents, I put the cards in my colleague’s cheap reader and they popped right up. :-(A for design. F for functionality - In This Instance. I have not tried it elsewhere so I cannot attest to its function in the real world. I will still buy U Green products in the future.

Stuck the USB-C side of this UGREEN up into the Pixel 8 phone's jack. MicroSD card is in the UGREEN, and the microSD card shows up in the phone's native Files app. (Use Notifications to "eject" the UGREEN from the phone.) So far so good, except I couldn't find if the File app has a function to Move stuff from the phone's memory to the MicroSD card. Figures it can display the external card, but there's no transfer function. Found a 'File to SD Card' app, which has precious little ads, and works fairly intuitively to do transfers. I'll have to give them 5 stars, too. So far, with UGREEN's help, I got the phone from 5 GB free to 60 GB free. 190 GB to go.The UGREEN warms up just sitting inactive in the phone's (or the chromebook's) USB jack. When the data transfer gets going, the UGREEN gets even hotter -- hotter than any device that I own, including wall transformers. Not hot enough to burn my fingers, but it surprises me.The phone has four seasons of a TV show that total about 62 GB. App said it would take 30 minutes to transfer. After 15 GB, the file-moving app crashed, exited, disappeared. Was that some self protection inside the microSD card from getting tooooo hot? Or the app lost its breath? Or the UGREEN has its own heat protection? I don't know.I also don't know if the assorted operating systems will magically assure that no data will be lost when I restart the transfer? Have I learned to transfer no more than a couple of GB at a time, instead of hugemongous 62 GB, assuming that "Nothing can go wrong?"I've noticed that the Moving app erases the source files as the last step, only after the transfer is complete. So, it wouldn't cost much if I just restarted the Move operation form the beginning.Obviously, the UGREEN has no through-power (or whatever it's officially called), so when it's hanging from your cellphone doing transferring operations, you'll be using battery power. I didn't time anything; maybe a move runs around a GB per minute. Last time I tried that on Windows, it took hours per GB, so whatever the exact numbers, I'm not complaining.After reaching maximum temperature and crashing the Move app, I removed the UGREEN from the phone 10 minutes ago, and it's already 100% back to room temperature. It may get hot, but it apparently radiates its heat efficiently. If I had an infrared thermometer, I'd love to know how hot the UGREEN really gets. I'd google if the temperature isn't outside the limits of what microSD cards are supposed to be able to endure.It's a lot of data. Next step is to back up the microSD card. I have full sized SD cards in my toolbox, and the UGREEN can hold a micro and a full-sized card, which should be convenient for backing up the data. But I'll see if processing two cards in the single UGREEN doesn't result in the UGREEN melting down into a conflagration.

Very fast, works well and really like the USB or USB-C compatibility. I like the different slots for the different sized SD cards too. Don't need any other adapters with this unit and really like not having to deal with a cable. Great all in one reader.

Working good, seems to read everything i put in there and it is a nice convenient size for desk and mobile usage. I only wished the USB A/C caps were captive so it would be harder for me to lose them. I used braided fishing line and a tiny hole in each the cap to solve that problem.

Awesome Product!!! This can connect to any of my devices, including my phone, tablet, computer, and more! It is very fast when transferring files and is the perfect size. It reads both SD and Mini SD cards. Great design Ugreen! Thank you!
