USB4 CFexpress 4.0 Type B Card Reader - Fast Active Cooling

In this review we look at the USB4 CFexpress 4.0 Type B Card Reader and why it makes sense for photographers and video professionals who need a compact, highspeed reader that stays cool under sustained transfers. The bottom line: this reader is for users with modern Macs, iPads, Chromebooks or USB4/Thunderbolt 4 hosts who want nearSSD throughput from CFexpress 4.0 Type B cards and a builtin cooling solution to keep speeds stable. It is not ideal for some Windows laptops with Thunderbolt 3 or certain USB4 implementations, so compatibility checks are important before purchase.

Key Features

• Maximum Compatibility: Plug and play with USB4, Thunderbolt 4 and USBC equipped Macs, iPads, Chromebooks, tablets and smartphones for broad device support.
• High Transfer Rates: Supports CFexpress 4.0 Type B cards with tested read speeds over 3300MB/s on a MacBook Air M2 and up to 1600MB/s with older CFexpress Type B cards.
• Active Cooling: Builtin silent turbo cooling fan helps maintain sustained performance during long transfers and batch offloads.
• Mobile Ready: External USBC PD auxiliary power port solves card reading abnormalities caused by insufficient OTG power on some tablets and phones.
• Included Accessories: Ships with a TB4/USB4 cable and a USB AC cable so users can connect to a range of hosts right away.

Who It's For

The reader is aimed primarily at creative professionals and advanced enthusiasts who own CFexpress 4.0 Type B cards and use Mac or USB4/Thunderbolt 4 hosts that can utilize full bandwidth; the active fan and PD input make it suitable for long shooting days and onlocation transfers. It is also a good option for iPad and tablet users who need OTG support and higher reliability when powering demanding media cards.

People who should look elsewhere include Windows laptop users with only Thunderbolt 3 ports or those whose machines have known USB4/Thunderbolt 4 compatibility quirks, since the manufacturer specifically warns about those combinations. Also avoid this reader if you only use older, lower speed cards and have no need for active cooling or PD power.
