Product FAQ
Questions about setup, fit, and cooling.
Which phones fit the KryoZon S9?
The S9 supports phones up to 92 mm wide. Use the magnetic attachment with a compatible magnetic phone or case, or use the clip when a magnetic connection is unavailable.
What power adapter does the S9 require?
Use a Type-C power source rated at 12 V / 2.5 A or higher. This is required for the S9's rated 30 W operation; a basic 5 V USB port is not sufficient.
Is the S9 completely silent?
The cooling end is fanless, so it produces no fan noise. The water-circulation pump is rated below 30 dB, so the complete system is quiet but not completely silent.
What cooling modes does the S9 have?
The S9 provides three modes: High, Low, and AI. Select the mode that matches the workload and the amount of cooling needed.
Can I mount the S9 on a streaming stand or tripod?
Yes. The S9 has a standard 1/4-inch brass thread designed to fit most streaming stands and tripods.
How does the S9 cooling system work?
The S9 combines semiconductor TEC cooling with water circulation. Its cooling end has a 60 x 60 mm contact surface and connects through a 1.2 m tube.
What is included with the S9?
The package includes the cooler, power cable, clip, and user manual. A power adapter is not listed among the included items.
What protection features are built into the S9?
The S9 includes an overheat alert and automatic shutoff protection. Its display also shows the temperature in real time.
