Anker’s new $35 MagSafe gadget sticks SD cards to your iPhone

Anker's next puck-shaped accessory is an SD and microSD card reader called the MagGo USB-C adapter that can be used with laptops, tablets, and smartphones. When connected to an iPhone 15 or 16, it can also enable ProRes 4K recording at 60 frames per second if the memory card supports at least 220 MB/s write speed and 256 GB capacity.

The MagGo USB-C adapter—available in white, black, or teal for $34.99 from Anker or Amazon—is MagSafe compatible, so it attaches to the back of an iPhone and stays out of the way when shooting video. Because it ultimately blocks both ways an iPhone can be charged, Anker has included an additional USB-C port on the MagGo that transfers up to 42.5W of power.

Anker promises transfer speeds of up to 312MB/s, which is the theoretical maximum of UHS-II memory cards. The speeds you get may be lower depending on the type of card you're using, or even how long the card has been in use. If you have an SD or microSD card with less than 220MB/s, you can still use the MagGo to record video externally from an iPhone 15 or 16—it'll just be limited to lower frame rates and possibly even lower resolutions.
