Key features

Reader role

a USB-C reader with two active SD slots, one active microSD/TF slot and a magnetic compartment for four spare cards.

Host connection

integrated USB-C cable; the host port must support USB data or OTG.

Card layout

Active: SD1, SD2 and microSD/TF. Passive storage: 2 × SD plus 2 × microSD under the magnetic cover..

Practical speed

Up to approximately 170MB/s with a suitable high-speed card and host. Simultaneous activity shares available bandwidth.

Model check: Similar-looking UGREEN readers can differ in host plug, card protocol, simultaneous access, extra USB ports and charging. Match SKU 55886 rather than buying by appearance alone.

Ports, slots and connection map

Host side: integrated USB-C cable; the host port must support USB data or OTG.

Reader and accessory side: Active: SD1, SD2 and microSD/TF. Passive storage: 2 × SD plus 2 × microSD under the magnetic cover..

Extra function: The storage recesses are not reader slots. The cover is magnetic, but the case is not advertised as waterproof, dustproof, crushproof or impact-certified.

Direction rule: A card reader is a host accessory. It must connect to a device that can act as a USB host; connecting two accessories together does not create a host.

Speed explained without the marketing blur

USB/interface ceiling

Up to 5Gbps USB interface bandwidth; the actual card pathway is advertised up to 170MB/s.

Memory-card ceiling

Up to approximately 170MB/s with a suitable high-speed card and host. Simultaneous activity shares available bandwidth.

UHS generation

SD 3.0 / high-speed UHS-I-class workflow as shown in exact media; slot shape does not establish UHS-II operation.

Real-world result

The slowest link wins: card, slot mode, reader controller, host port, file system, thermal state, file sizes and simultaneous activity all matter.

Never equate 5Gbps or 10Gbps with card speed. USB values describe theoretical link signalling. SD and microSD media usually operate at much lower sustained rates, and many small files transfer more slowly than one large sequential file.

Card formats, capacity and file systems

Supported card families

SD, SDHC, SDXC, microSD/TF, microSDHC and microSDXC.

Capacity boundary

Exact live UGREEN India media states up to 2TB. Some external regional listings say 4TB, so this draft keeps the conservative exact-live 2TB claim.

File-system caveat

The card must use a format the host understands. exFAT is common for large removable media; FAT32 has file-size limits; NTFS and vendor-specific formats may not mount on phones/tablets.

Write-protect reminder

A full-size SD card with its lock tab engaged may be readable but not writable. The reader cannot override the card's mechanical write-protect state.

Simultaneous access and shared-resource behaviour

Supported pairs are SD1 + SD2 or SD1 + microSD/TF. SD2 + microSD/TF is not supported because those positions share operation.

Shared bandwidth

Two cards or attached peripherals divide the bandwidth available through the single host connection.

Shared power

Bus-powered readers and USB peripherals depend on host power. High-draw drives may disconnect or fail to mount without an appropriate powered path.

Copying card-to-card

The computer or mobile host mediates the copy. The reader is not an autonomous duplicator and does not copy files when disconnected from a host.

Safest workflow

For irreplaceable media, copy one card, verify the files, create a second backup and only then erase or reformat the original.

Compatible devices and systems

Compatible device class: USB-C laptops and desktops, USB-C iPhone and iPad models, and OTG-enabled USB-C Android phones or tablets.

Operating systems: Windows, macOS, Linux, ChromeOS, iOS/iPadOS and Android where USB mass-storage/OTG is supported..

Mobile rule: USB-C shape alone is insufficient; the mobile device must expose USB host/OTG storage and support the card file system.

USB-C is only a shape

A USB-C port can be charging-only, data-capable, OTG-capable or video-capable. Confirm the exact host function.

Apps and permissions

On phones/tablets, use Files, Photos or the manufacturer's supported file manager and allow removable-storage access when prompted.

Cases and clearance

A thick case can prevent full plug insertion. Remove it temporarily rather than forcing the connector.

Managed devices

Corporate policy, encrypted cards or restricted mobile profiles can block removable media even when hardware is compatible.

Setup and usability guidance

  1. Confirm SKU 55886, the required host connector and the exact card format before insertion.
  2. If using a phone or tablet, enable or confirm OTG/USB-host storage and make sure the battery has enough charge.
  3. Insert the memory card straight into its matching slot in the orientation shown by the slot label. Never force it.
  4. Connect the reader to the host. Wait for the removable volume to appear in Files, Finder, File Explorer or the supported mobile app.
  5. Copy a small test file first. Then start the main transfer and keep the device, cable and cards still.
  6. Verify copied folders, file counts and several representative files before treating the transfer as a backup.
  7. Use Eject or Unmount, wait for activity to finish, then disconnect by the connector housing rather than the cable.

What this product does

  • a USB-C reader with two active SD slots, one active microSD/TF slot and a magnetic compartment for four spare cards.
  • Provides Active: SD1, SD2 and microSD/TF. Passive storage: 2 × SD plus 2 × microSD under the magnetic cover..
  • Works within the documented speed and compatibility limits.
  • Supports the stated host and card families when the operating system can mount them.

What this product does not do

  • not a five-slot reader, not a waterproof backup case, not a UHS-II promise and not able to use SD2 with TF simultaneously.
  • It does not repair corrupted media, recover deleted files or guarantee that damaged cards will mount.
  • It does not make one copy into a backup; keep another verified copy on separate storage.
  • It does not guarantee every illustrated device, card capacity or speed without the required host capability.

What to do

Do: label cards

Separate blank, active and backed-up cards. Locking or labelling completed media prevents accidental erasure.

Do: verify before erasing

Open several copied files and compare counts or checksums for critical work.

Do: keep connectors clean

Use a dry, dust-free environment and store the reader where slot contacts are protected.

Do: eject safely

Unmount every active volume and wait for activity to stop before removal.

What not to do

Do not: remove during writing

Disconnecting during import, deletion, formatting or metadata updates can corrupt the file system.

Do not: force media

Wrong orientation or the wrong card family can bend contacts or crack the card.

Do not: format the wrong disk

Confirm the volume name, capacity and path before erase or format operations.

Do not: trust one copy

Portable cards fail, get lost and can be overwritten. Maintain a separate verified backup.

Warnings and limitations

Heat and moisture: keep the reader dry and ventilated. Mild warmth during sustained transfer can be normal; disconnect if there is unusual heat, smell, deformation or repeated resets.

Power: The storage recesses are not reader slots. The cover is magnetic, but the case is not advertised as waterproof, dustproof, crushproof or impact-certified.

Card handling: do not touch contacts, bend cards, use cracked adapters or insert nested adapters that do not fit cleanly.

Formatting: formatting deletes the file-system index and can make recovery difficult. Back up first and confirm the target device's preferred format.

Critical data: no reader can guarantee recovery from failing media. Stop repeated write attempts on a card showing errors and seek professional recovery help if the files are irreplaceable.

Troubleshooting

Card does not appear

Reseat the card and reader, confirm slot orientation, test one card at a time, remove an obstructing case and check OTG/file-system support.

Card is read-only

Check the SD lock tab, operating-system permissions, card health and whether the file system was mounted read-only after errors.

Transfer is slower than expected

Use one card, a direct high-speed host port and large sequential files; confirm the card's own sustained rating and negotiated UHS mode.

Reader disconnects

Remove high-power USB peripherals, connect a suitable PD/powered path where this exact model supports it, and avoid loose extensions.

Phone cannot see files

Use the Files/Photos app, enable OTG, grant storage permission and verify the card uses a phone-supported format such as exFAT/FAT32.

Copied file will not open

Compare the original, copy again to a different destination and stop using a card that reports I/O, CRC or corruption errors.

Research and media reconciliation

Exact gallery establishes the three active slots, 170MB/s card maximum, four passive storage spaces and the restricted simultaneous combinations. A tiny corrupted gallery asset and external 4TB claims were excluded.

Visual-media decision: Eight useful exact images are embedded once. The tiny corrupted eighth asset is documented and excluded; the retained visuals distinguish three active slots from four passive storage spaces and keep the 170MB/s and OTG claims qualified.

Excluded exact-media slide: Excluded because the exact live asset is corrupted/tiny and provides no legible product information.

Research method: exact live Shopify product record and gallery were visually reviewed, then claims were checked against exact-SKU UGREEN India or official UGREEN regional pages. Duplicate, corrupted or conflicting artwork was documented and not embedded.

Source discipline: no UHS-II, capacity, speed, simultaneous-access or charging claim was inferred from slot shape, connector colour or a related product family.
