SUNTRSI Y-BD 4-in-1 SD Card Reader with USB, USB-C and iPhone Charging Port

Multiple connection options and a built-in charging port make the SUNTRSI Y-BD a practical way to access card files across phones, tablets, and computers. Its SD and microSD slots let you transfer photos and other files from a camera card without first moving them to a separate computer.

The compact reader supports USB, USB-C, and micro-USB connections, with a port for iPhone and iPad use. During file transfers, the added charging port can charge a connected iPhone or iPad at the same time. For Android phones, OTG must be enabled to use the reader.

Who it’s for

Need to check camera photos on a phone while keeping it plugged in to charge? The dedicated charging port supports charging during file reading and transfer.

Compared with a single-connection card reader, the Y-BD brings several connector options and two card formats into one portable accessory. Its listed operating system support includes Android and Mac OS, and it supports iPhones and iPads running iOS 8.0 or later. Android users need OTG enabled. Buyers often praise its compact size and file-transfer convenience, while compatibility feedback is mixed across individual devices, checking that the device supports the relevant connection is a useful step before transferring files.

Usage tips

For Android, turn on the phone’s OTG function before connecting the reader. On iOS 13 and later, card files can be viewed in the Files app. For iOS 9.2–12.4, the provided guidance describes viewing full-resolution images by long-pressing a thumbnail in Photos. The 512GB capacity ceiling is useful when choosing a card for larger collections of camera photos or other files. Its slim form also makes it easy to keep on hand for card access away from a desk.

Is it worth it?

A solid pick if you want one compact reader for SD and microSD cards, with connection choices for common mobile and computer setups. The combination of two card slots, multiple interfaces, and charging during transfers makes the SUNTRSI Y-BD well suited to checking camera images, organizing files between devices, and handling card-based backups on the go.
