The upgraded CoolHyper cooling system uses a silicone thermal pad, aluminum heat sink, and honeycomb ventilation structure to help transfer and release heat more efficiently. Strong MagSafe compatibility comes from built-in magnets that provide stable alignment with compatible chargers, stands, power banks, wallets, and other magnetic accessories. The A18 Ultra Slim Aramid Fiber Case combines aramid fiber and aluminum alloy in a practical design for users who want slim coverage, camera-area protection, and magnetic accessory compatibility. Its listed Pro Max weight is approximately 27g, supporting a lightweight everyday carry experience. Manual measurements may have minor discrepancies, but these variations will not impact practical use.
