Product description
High‑speed transfers: This reader uses a USB 3.0 interface capable of up to 5 Gbps for faster file moves compared with legacy USB 2.0 (480 Mbps). Typical operation lets you move gigabyte‑size files in seconds, and the unit remains backwards compatible with USB 2.0 and 1.1 hosts.
OTG plug‑and‑play: The adapter supports OTG functionality so you can connect directly to compatible phones and tablets without additional software. Just plug the appropriate connector into a device and access, copy, or view files in real time.
Three‑slot layout: The tool includes three card bays that accept SD and microSD (TF) formats and can be used concurrently. Both SD and microSD slots are rated to handle transfers up to about 104 MB/s. Supported formats include UHS‑I SDXC/SDHC/SD, MMC, RS‑MMC, microSDXC and microSDHC from cameras, action cams, dashcams, surveillance units and other devices.
Design and protection: The reader comes with protective end caps to keep dust and moisture out when not in use. Its slim footprint fits easily into camera bags, backpacks, or on a keychain, making it practical for field work and travel. The housing is a sturdy metal alloy that gives a solid feel while remaining lightweight.
Compatibility and contents: The package contains the multi‑slot card reader (memory cards not included). It works with USB‑C and USB‑A hosts — ranging from recent smartphones and tablets to laptops and desktops — including many modern iPhone, MacBook, Windows laptop, and Android phone models (adapter compatibility varies by device and OS).
Pros
- Fast USB 3.0 transfers with USB‑2/1.1 compatibility
- Three simultaneous card slots supporting UHS‑I/SDXC
- Small, metal body with protective caps for travel
Cons
- Secondary side port limited to USB 2.0 in some units
- Memory cards are not included
- Actual speeds may fall short of the theoretical maximum
VerdictA handy, pocketable card reader that brings fast USB 3.0 transfers and plug‑and‑play OTG support to phones, tablets, and computers. The three‑slot layout handles full‑size SD and microSD cards (including UHS‑I/SDXC/SDHC) and can read both slots at around 104 MB/s. Build quality feels solid thanks to a metal casing and protective end covers. Some users note the auxiliary port is limited to USB 2.0

StAugBchBum 5/5
Small but capable
Multiple ports in a compact, simple package — exactly what I wanted.
-
John McCrone 4/5
Good value, minor caveat
Transfers aren’t always as fast as advertised, which is fairly common. The main USB‑A connector runs at USB 3.0, but the side port is only USB 2.0 — that would be nicer at 3.0. Card slots perform well and the metal build feels solid. I’ll be carrying it on my keychain.

Simple and effective
Restoring old camera gear meant I needed a basic reader — this was exactly that. No extra features, just reliable performance. A solid find.

Antonio Linton 5/5
Tiny, fast and dependable
This compact reader moves large photo files much quicker than older models. It’s small enough to keep on a keyring so you always have it when you need to offload images. Works with full‑size SD, microSD and standard USB drives — no drivers required. The portability is what sold me.
