Overview
Not a Type-C dongle, this reader plugs into a regular USB Type A port on a laptop or desktop and reads two card types at once. Plug and play operation means no driver install, and the metal body is small enough to carry in a camera bag.
The reason to buy is quick card access for camera or phone photos with two slots in a small metal body. The limit is the long list of card types it refuses, and the listing says nothing about a cable or Type-C adapter.
Who it's for
Picture a camera bag with a laptop that has a free USB port and a few memory cards to empty. Someone with a slim laptop that has only Type-C ports, or a pro camera with a different card standard, needs another reader.
Pros and cons
- Two card slots in one reader
- Plug and play, no driver
- Fast USB 3.0 link
- Reads cards from cameras and phones
- Type A only, no Type-C
- Many card formats refused
- Not for pro card standards
- Contents of the box not listed
Performance notes
Transfer speed is capped by the USB link and by the card itself, so a slow card stays slow in a fast reader. The two slots are separate, and the listing does not say whether both read at the same time. The metal body also helps spread heat during long transfers.
