Product FAQ
Questions about setup, fit, and cooling.
Which phones are compatible with the K12?
The K12 works with iPhone and Android phones that have MagSafe or a compatible magnetic ring. It uses magnetic attachment and does not include a clip mount.
Can I use the K12 with a phone case?
Yes, if the case is MagSafe-compatible or fitted with an adhesive magnetic ring. A non-magnetic case will need a compatible ring before the cooler can attach securely.
What charger does the K12 need?
Use a PD power source rated at 5 V / 3 A or higher through the Type-C port. Lower-current USB sources may prevent the 15 W cooler from starting or reaching full output.
How loud is the K12?
The K12 fan is rated at 32 dB. Its low-noise design is suitable for gaming, voice chat, and recording, although microphone placement and room noise will affect what is captured.
How much does the K12 weigh?
The K12 weighs approximately 65 g, which keeps the magnetic setup compact for handheld gaming or recording.
Does the K12 use water cooling?
No. The K12 uses semiconductor TEC cooling with a fan. It does not use a water tank or external tubing.
What finish does the K12 use?
The K12 uses a vacuum-electroplated finish. Keep the contact surface and magnetic area clean and dry before attaching it to a phone or case.
