UGREEN SD Card Reader USB C, USB 3.0 Micro SD Card Reader 2

The Verdict

Let’s be blunt: most card readers under $20 are disposable junk. The UGREEN SD Card Reader USB C (model B07D1J88CF) is not that. It’s the one I’ve kept on my desk for two years, and it’s the one I’d buy again tomorrow if it died. Here’s why.

What you actually get

The box contains the reader itself — a compact aluminum slab roughly the size of a matchbox (about 2.2 x 1.1 x 0.4 inches) — plus a short lanyard. No cables, no drivers, no software. It’s plug-and-play on Windows, macOS, iPadOS, Android, and ChromeOS. The USB-C connector is built into the body, not attached via a dangling cable, which keeps it pocketable and means one less thing to lose.

Performance and build

The headline spec is USB 3.0 at up to 5Gbps. In real-world testing, that translates to roughly 90–100 MB/s read speeds on a UHS-I card — enough to offload a 32GB SD card in under three minutes. It reads UHS-I and UHS-II cards (the latter at UHS-I speeds), plus SDXC, SDHC, and microSD variants.

The dual-slot design is the killer feature. As shown in the product image, both slots sit side by side, and the reader handles simultaneous read/write to both cards. That means you can copy from a camera SD card to a microSD for your drone or phone without swapping anything. It’s a workflow saver.

Build quality is genuinely impressive for the price. The aluminum alloy housing isn’t just cosmetic — it pulls heat away from the controller chip during sustained transfers. I’ve moved 100GB+ of RAW files in one sitting, and the unit gets warm but never uncomfortable to hold. The spring-loaded slots click cards in firmly; there’s no wobble or half-seated connection issues.

What buyers consistently praise

Scrolling through the 229 ratings (4.6 stars), a few themes repeat. One verified buyer wrote: “Finally a reader that doesn’t disconnect mid-transfer. I’ve returned three others — this one just works.” Another noted: “Plugged into my MacBook Pro and it was instantly recognized. No drivers, no hassle.” The dual-slot functionality gets called out repeatedly as the reason people chose this over single-slot competitors.

Where it falls short

The biggest limitation: USB-C only. If you’re on an older laptop with only USB-A ports, you’ll need a dongle, which negates some of the portability. It also doesn’t support UHS-II speeds fully — if you shoot on a high-end camera with V90 cards, you’ll be bottlenecked to ~100 MB/s instead of the 300 MB/s those cards can deliver. That’s a niche complaint, but honest.

The included lanyard is nearly useless — thin, and the attachment hole is too small for any keyring thicker than a paperclip. Minor, but it’s the kind of detail that shows where corners were cut.

Who should buy this

Three buyer personas fit best:

1. The hybrid shooter — you use both a mirrorless camera (SD) and a drone/action cam (microSD). This reader handles both simultaneously, so you’re not carrying two readers.
2. The iPad Pro/tablet user — plug this into a USB-C iPad and you can import photos directly into Lightroom or Files. No laptop required.
3. The budget-conscious professional — you need reliable daily transfers but don’t shoot 8K RAW video that demands UHS-II speeds. This does 95% of the job at a fraction of the cost of pro readers.

FAQ

Q: Does it work with the Nintendo Switch?
Yes, but with a caveat. The Switch’s USB-C port supports data transfer, so you can read SD cards from it, but the Switch won’t recognize exFAT-formatted cards above 32GB without reformatting. Stick to FAT32 for Switch use.

Q: Can I read two cards at the same time?
Yes, and that’s the point. Both slots are active simultaneously, and the reader appears as two separate drives on your computer. You can drag files between them directly.

Q: Will it work with a USB-C phone?
Mostly. Android phones with USB-C and OTG support will recognize it. iPhones with USB-C (iPhone 15 and later) work too, but iOS won’t read NTFS-formatted cards without a third-party app.

The Verdict

Buy it if: you need a reliable, dual-slot USB-C card reader for everyday photo/video work and don’t need UHS-II speeds.
Skip it if: your workflow is USB-A only, or you shoot demanding 8K/ProRes footage requiring UHS-II V90 cards.

At 4.6/5 stars, this is the rare accessory that earns its rating. It’s not perfect — the USB-C-only design and lack of UHS-II support are real limitations — but for the vast majority of photographers, videographers, and tablet users, it’s the last card reader you’ll need to buy.

Rating: 4.6/5 — Buy it with confidence.
