5-layer cooling devices,3-second cooling :Air cooling plus ice magnetic,dual micro-channel heat dissipation, composite structure design,efficient cooling. Exposed heat dissipation channel:Metal structure heat dissipation air outlet, combined with axial flow fan blades, increases air flow and quickly dissipates heat. No vibration and low noise:Brushless silent motor, lower than standard value noise of 27dB, easy to enjoy silent cooling. Anti-condensation:Automatic adjustment reduces temperature difference and prevents condensation inside the mobile phone, protecting the mobile phone more safely. Wide compatibilities:65mm-89mm adjustable clamp length, suitable for most cell phone models.
