iFarmRecommended hardware for your iPhone farm
For a farm of up to 15 iPhones on one Mac we recommend three things: a Cambrionix SuperSync15 USB hub to charge and connect the phones, an AC Infinity MULTIFAN S7 USB fan to keep them cool, and a ventilated multi-device rack such as the Belkin Store and Charge Go to hold them upright with space between them. For 4 phones or fewer you can plug straight into the Mac and only need the fan and a stand.
The short list
| What | Our pick | What it does | Maker's page |
|---|---|---|---|
| Charging and data hub | Cambrionix SuperSync15 | 15 USB ports that charge and connect every phone to the Mac at the same time | cambrionix.com |
| Cooling | AC Infinity MULTIFAN S7 (AI-MPF120A2) | Two quiet 120 mm fans, powered by USB, blowing across the phones | acinfinity.com |
| Phone rack | Belkin Store and Charge Go, 10 devices, fixed dividers (B2B141) | Holds phones upright in separate, ventilated slots | belkin.com |
Details below are from each maker's own page, as of November 2026. Prices and specs change, so check the maker's page before you buy. iFarm doesn't sell these products and isn't paid to recommend them.
Which setup for how many phones
| Phones | Hub | Cooling | Rack |
|---|---|---|---|
| 1–4 | None: plug into the Mac's own ports (a Mac mini M4 has 5 USB-C ports) | One MULTIFAN S7 | A simple stand with gaps, or the Belkin rack |
| 5–15 | One SuperSync15 | One or two MULTIFAN S7 | One or two Belkin racks (10 phones each) |
| 16–30 | Two SuperSync15, each on its own Mac port | Two to three MULTIFAN S7 | Two to three Belkin racks |
How many phones a Mac can run depends on its memory: about 140 MB per phone, so 8 GB runs 5–10, 16 GB runs 10–20 and 32 GB or more runs 20–30. iFarm's Health page shows the real numbers for your Mac. See how many iPhones a Mac mini can run.
Cambrionix SuperSync15: charging and connection
The SuperSync15 is a professional USB hub built for charging and syncing many phones and tablets at once. For an iPhone farm it does the two jobs a cheap hub can't do reliably: it gives every port its own steady power, and it keeps a data connection to every phone so iFarm can control it.
From Cambrionix's specifications:
- 15 downstream USB-A ports and one upstream port to the computer.
- Data up to 5 Gbps per port (USB 3.2), so every phone stays connected to iFarm at the same time.
- Charging up to 12 W per port, 180 W in total, from its own mains power supply (included). When the hub is connected to a computer it runs in sync mode, where Cambrionix quotes a lower charge rate per port. That's enough to keep phones topped up while iFarm uses them.
- Size: 199 × 73 × 42 mm.
What you also need:
- One cable per phone. The hub's ports are USB-A, so use USB-A to Lightning cables for iPhones with Lightning and USB-A to USB-C cables for iPhone 15 and later. Use data cables, not charge-only ones.
- A way to reach the Mac. The hub connects to the computer with a USB-A cable. Recent Macs, including the Mac mini M4, only have USB-C ports, so use a USB-A to USB-C cable or a good USB-C adapter, plugged straight into the Mac (not into a monitor or desk dock).
- A second hub on a separate Mac port if you go past about 15 phones.
Tip: Plug the hub into the Mac itself, not into a monitor's or a desk dock's USB hub. Those often drop the phone's data connection as soon as iFarm starts its helper.
AC Infinity MULTIFAN S7: cooling
Phones that run all day with their screens on and keep charging get warm, and a hot iPhone slows down, dims its screen and stops charging. A small fan blowing across the phones keeps them comfortable.
From AC Infinity's product page:
- Two 120 mm fans joined by a 30-inch cable, so they can cover a whole row of phones.
- 104 CFM of airflow in total at 19 dBA, quiet enough for a room you work in.
- USB powered (2.9 W), with an in-line speed controller and power switch. Power it from a USB-A port on a dock, a phone charger or the wall adapter, not from the SuperSync15's phone ports.
- $22.99 on AC Infinity's site (November 2026).
How to place it: lay the fans on the desk behind or beside the rack, blowing across the phones rather than at one spot. One MULTIFAN S7 covers about 10 phones. Take the phones out of their cases, keep their screens dim, and on iPhone 15 and later turn on the 80% charging limit (Settings → Battery → Charging). See keeping iPhones running 24/7 for more.
Belkin Store and Charge Go: the phone rack
A rack keeps the phones upright with a gap between each one, so air can flow and cables don't tangle. We recommend Belkin's 10-device Store and Charge Go with fixed dividers.
From Belkin's product page:
- Holds up to 10 devices upright between fixed dividers, with front and side slots for the cables.
- Ventilated design to help keep devices at a normal temperature.
- Four holes for fixing it to a desk; a bracket for wall mounting (wall mount sold separately).
- Comes with a surge-protected power strip with 10 outlets. With a SuperSync15 you don't need it for the phones, but it's handy for the hub's and the fan's power.
- $369.99 on Belkin's site (November 2026).
Cheaper option: for 4 phones or a tight budget, any vertical stand with slots that leaves a finger's width between phones works. What matters is the gap and the airflow, not the brand.
Putting it together
- Put the Belkin rack on a desk or shelf near the Mac, with room behind it for the fan.
- Stand the phones in the slots without cases, screens facing the same way.
- Plug the SuperSync15 into mains power and into the Mac with a USB-A to USB-C cable.
- Connect each phone to the hub with its own data cable, through the rack's cable slots.
- Place the MULTIFAN S7 so it blows across the row of phones and plug it into USB power. Start on a low speed.
- Open iFarm. Each phone should appear with a green USB tag. Follow the setup guide for the first start of each phone.
- After an hour of running, open iFarm's Health page to check battery, temperature warnings and how much room your Mac has for more phones.
Frequently asked questions
Do I need a SuperSync15 for 4 phones?
No. A Mac mini M4 has five USB-C ports, so up to 4 phones can plug straight into the Mac with USB-C cables. Get a hub when you go past what the Mac's own ports can take.
Can I use a cheaper USB hub?
You can, as long as it has its own power supply, enough power for every port at once, and data on every port. Many cheap hubs share a small power budget between ports or are charge-only, and phones then drop off or drain while iFarm uses them. That's why we recommend the SuperSync15 for bigger farms.
Does the SuperSync15 work with a Mac?
It connects to a computer with a standard USB cable and passes each phone through as a normal USB device, which is what iFarm and Xcode need. Because the hub's host connection is USB-A, use a USB-A to USB-C cable on Macs that only have USB-C.
Is iFarm affiliated with Cambrionix, AC Infinity or Belkin?
No. These are products we recommend because they suit the job. iFarm doesn't sell them and isn't paid to recommend them. All product names are trademarks of their owners.
