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

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.

Purchased a USB 3.0 UGREEN reader similar to this supposed "USB 3.2" device. Tested with Samsung Pro Plus 128GB microSD, the results speak for themselves! The UGREEN USB 3.0 device out performed the TEC USB 3.2 hands down. I'm finding UGREEN to be a solid product and will continue to stick with them. UGREEN 168 MB/s versus TEC 94 MB/s. I especially like the full insertion of the MicroSD and push to release.

Works as expected. My kids digital cameras have a SD card and this has allowed them to take the pictures and transfer them. another bonus - doesnt take up much space

Haven't use it yet

Got it. Tried it. It worked very well with what I needed for it to do.

Works great with every card I've tried. Excellent for the price. Feels premium. Caps stay on tightly. I especially like that it has the little spring loaded push to eject function rather than just pulling the card out.

I have tried several card readers and sd card adapters on different devices, none was able to read and let me transfer the photos and videos from a corrupt Samsung 128gb microSD card that was in my phone. I bought this to try out and was able to extract all the images and video clips and place them in my SSD on my PC. Lifesaver and worth every penny.

another great way to move files from iphone to notebook and vice versa. have used often with both card sizes. works like a charm.only downside for me is that i have to remove phone from case to make functioning contact with USB C port on phone.
