Configuration d’enregistrement iPhone Pro : connecter un SSD, un micro USB-C et un refroidisseur

“My iPhone recording rig cooler, SSD and USB-C mic can all plug into the phone” is an easy assumption to make while packing an iPhone Pro for a shoot. The KryoZon S9 product specifications call for a separate 12 V / 2.5 A Type-C supply, while Apple’s iPhone USB-C guidance lists external storage and microphones as device types without confirming that your chosen hub runs both together. Draw the two power and data paths before you mount anything; then check the complete rig in the recording app you intend to use.

A port map separates iPhone peripherals from cooler power

Start your equipment list with the exact iPhone Pro model, recording app and intended video format. Add the SSD, its cable, the USB-C microphone and any hub you plan to use. On a second line, list the cooler, its supply and the space you have for its pump and water container. This makes an easily missed distinction visible: the phone’s USB-C connection is the proposed path for recording peripherals, not the planned power source for the S9.

Apple lists external storage and microphones among the device classes that can connect to an iPhone’s USB-C connector. The same page lists iPhone 15, 16, 17 and 18 Pro models for USB 3 external ProRes recording. Those statements establish useful starting points, but they do not establish that an SSD and a particular USB-C mic will work simultaneously through a particular hub.

Write the proposed connections in plain language rather than treating a shopping list as a wiring plan:

• Phone data path: iPhone Pro USB-C connector → proposed compatible hub → SSD and USB-C microphone.
• Cooler power path: separate compatible supply → S9 Type-C connection.
• Physical path: phone mount and cooler head → tubing and pump positioned clear of the camera, controls and working area.

The first line is a topology to verify, not a promise of hub compatibility. If you already own the phone, app, hub and peripherals, assemble them before buying the remaining pieces. If you do not, keep the hub choice provisional until you can confirm its port arrangement, power provisions and behavior with the actual recording setup. A neat drawing prevents the cooler’s separate supply from disappearing into the same box labeled “USB-C accessories.”

External ProRes requirements start with the recording format

For external ProRes recording, compare the SSD’s specifications with the requirements for the format and frame rate you intend to record. For direct external ProRes recording on the iPhone 15–17 Pro models covered by Apple’s ProRes support page, Apple specifies an exFAT-formatted external device, says password-encrypted drives are unsupported, and calls for a USB 3 cable rated at least 10 Gbit/s. Its stated minimum external-drive write speeds are 220 MB/s for 4K60 ProRes and 440 MB/s for 4K120 ProRes.

Check the intended format first, then check the whole proposed SSD path: drive format, drive write capability and cable rating. A drive advertised with a high headline speed does not tell you which cable is in the bag or how a proposed hub will behave in your rig. Keep the drive maker’s specifications handy, and verify recognition and recording on the iPhone rather than treating the number printed on the enclosure as a completed workflow test.

Apple’s current USB-C page also lists iPhone 18 Pro models for USB 3 external ProRes recording. The detailed exFAT, cable and 4K60/4K120 drive-speed requirements quoted above come from a separate page that names iPhone 15–17 Pro. If you are building around an iPhone 18 Pro, check the documentation for that model and your selected recording mode instead of automatically extending every detail of the older-model page.

Record the answers beside your equipment list: phone model, selected format, drive format, rated write speed and cable rating. Leave the actual recording result blank until the preflight. That small distinction keeps a documented requirement separate from something your own combination has demonstrated.

A USB-C mic and SSD need a verified shared path

The microphone is the part that can turn an apparently simple external-SSD plan into a compatibility check. Apple’s USB-C device list names both microphones and external storage, but it does not test their simultaneous use through a specific hub or confirm that a particular recording app selects a connected mic. Treat a powered hub as a possible layout to investigate, not as a guaranteed solution for every microphone and SSD.

Before mounting the phone, inspect the proposed hub’s actual connectors. Identify where the SSD cable would go, where the microphone would go and how the hub itself is powered, if applicable. Do not count a port twice: a connector reserved for one cable cannot also accept another accessory. Check the hub maker’s compatibility information for your exact equipment, then use the complete setup to settle the question that specifications alone cannot answer.

Verify the audio path independently of the video path. In the chosen recording app, look for an indication of the active input if the app provides one. Make a short recording while speaking a recognizable phrase into the intended microphone, then play the file back through a known listening device. A visible microphone connection does not replace listening to the saved file. If the app offers an input choice, note the selection so you can repeat it after reconnecting cables.

Next, confirm where the app says it is writing the video, and inspect the saved file on the intended drive after the test. If either audio or storage fails the check, simplify the connection chain and test one peripheral at a time before rebuilding the proposed shared path. This troubleshooting order tells you more than repeatedly swapping all the cables at once.

The S9 cooler needs its own supply and water setup

The KryoZon S9 Water Cooling Phone Cooler - Fanless Liquid Cooling combines water circulation with a semiconductor TEC. Its approved specifications list a fanless cooling head, a pump rated below 30 dB by the manufacturer, a 75 g cooling-end weight, magnetic and clip attachment, and a 1/4-inch brass mounting thread. Those are equipment specifications—not a measured microphone-noise result or an assurance that a particular phone will record for longer.

Plan a separate cooler supply. The S9 product specifications list Type-C input and 12 V / 2.5 A operation. The printed operating instructions recommend a compatible 12 V / 3 A fast-charging power source. The recommendation is for the supply you select; it is not an instruction to power the S9 from the iPhone’s recording connection.

Water placement is part of this rig, not an afterthought. The operating instructions say to submerge the pump completely in room-temperature water in a large-capacity container before use and prohibit operating it dry. They then direct the user to fix the cooling head to the phone and press the inline controller button to start cooling; a two-second long press switches it off. Arrange the container and supply before the phone goes onto a stand, and follow those steps when powering the cooler.

The S9 specifications list a 1.2 m tube and support magnetic or clip attachment for phones up to 92 mm wide (KryoZon product page). Check the physical route on your own mount: the cooling head must sit where you intend it to sit, while the tube needs a sensible path to the pump. Treat the listed 75 g as the weight of the cooling end only, not the weight of everything you must carry.

Mounting clearance matters before any cable is tightened

A recording rig can look orderly on a desk and become awkward once the iPhone Pro is framed for a shot. With the power still off, position the phone as you will actually film. Check whether the proposed cooler-head location leaves the camera view, screen controls, USB-C plug and mounting points accessible. Then trace the tube toward the pump and the mic and SSD cables toward the proposed hub. This is a fit check, not a claim that one mounting position works for every phone case or stand.

The S9 specifications list a 1/4-inch brass thread, magnetic and clip attachment, and a 1.2 m tube. Use those details to sketch possible placements, then confirm clearance with the actual phone and support you own. A thread in a specification is an available mounting option; it does not establish that a specific tripod, clamp, cage or camera configuration has been checked with this setup.

Place the water container on a stable surface in a position that lets you follow the instruction to keep the pump fully submerged while operating. Keep the connection layout visible enough to inspect without disturbing the shot. If the proposed arrangement requires a cable to be stretched tight, change the arrangement before recording rather than hoping it will stay in place.

Finally, perform the mounting check in the orientation you will use, whether portrait or landscape. Look through the chosen app’s live view, touch the controls you expect to need and make sure you can reach the power and recording connections. A diagram answers which devices connect; this hands-on check answers whether you can operate the assembled rig.

A short recording check completes the connection plan

Power and recognition are not the final checks. Once the rig is positioned, connect the peripherals in a repeatable order and note which device appears in the phone and recording app. Start with the SSD path, add the microphone through the proposed hub, and confirm that the intended storage destination and audio input remain available together. This is the point at which your particular iPhone, hub, SSD, mic and app either support the proposed workflow or require a different arrangement.

1. Confirm the target format. Select the mode you intend to shoot. For the iPhone 15–17 Pro external ProRes modes described by Apple, recheck the relevant exFAT, USB 3 cable and drive write-speed requirements before pressing Record.
2. Confirm the destination. Check that the app presents the intended external-storage option, then record a short clip and find the saved file on the intended drive.
3. Confirm the audio. Speak into the USB-C microphone during the clip and listen to the saved file. Do not rely solely on a connected-device icon.
4. Confirm the cooler setup. With the pump fully submerged as directed in the operating instructions, start the separately powered S9 and check that its tubing and supply do not interfere with your intended framing or controls.
5. Review the file. Play back both picture and sound, inspect the file at its intended destination, and repeat the check after changing any cable, app setting or mounting position.

Write down the hub model, port assignments, app setting and connection order that worked on your own equipment. If the SSD disappears when the mic is connected, or the saved audio is not from the intended source, do not treat cooler placement as the fix: isolate the peripheral connection first. The iPhone recording rig cooler has its own power path; the unresolved shared USB-C path belongs to the phone, hub, SSD, microphone and app. For this setup, a verified short recording is more useful than an untested promise of a finished rig.

Frequently Asked Questions

Can I connect an external SSD and a USB-C microphone to one iPhone Pro?

Apple lists external storage and microphones as iPhone USB-C device types, but that does not confirm simultaneous operation through a particular hub. Check the hub’s proposed port and power arrangement, then test both devices in your recording app and inspect the saved file.

What SSD and cable do I need for external ProRes recording?

For the iPhone 15–17 Pro models named in Apple’s ProRes guidance, the external drive must be exFAT-formatted and the USB 3 cable rated at least 10 Gbit/s. Apple specifies minimum drive write speeds of 220 MB/s for 4K60 ProRes and 440 MB/s for 4K120 ProRes; check the requirements for your exact model and format.

Does the iPhone power the S9 cooler in this rig?

Plan a separate supply rather than using the phone’s recording connection. The S9 specifications list Type-C and 12 V / 2.5 A operation, while its operating instructions recommend a compatible 12 V / 3 A fast-charging power source.

What should I check before recording with the cooler attached?

Confirm camera and control clearance, SSD destination, recorded microphone audio and playback of a short clip. Before starting the S9, follow its instruction to keep the pump completely submerged during operation.
