Key Features of AULUMU A18 Ultra Slim Aramid Fiber Case

Premium Aramid Fiber with a Minimalist Feel

Aramid fiber is valued for its combination of strength and low weight. AULUMU uses 1500D aramid fiber in the A18 case, giving it a finely woven appearance and a technical finish while helping maintain a slim overall profile.Unlike bulky protective cases, the A18 uses a semi-cover design that reduces coverage around the phone's edges. This approach is intended for people who want a closer-to-bare-phone grip, a lightweight carry experience and a case that complements the original design of their iPhone.

• Fine-woven 1500D aramid fiber construction.
• Minimal additional bulk for everyday carrying.
• Refined black finish with a technical, understated appearance.
• Semi-cover design intended to preserve the original button feel.
• Lightweight construction for comfortable daily handling.

Protection note: The A18 is designed around a slim semi-cover profile. It should not be treated as equivalent to a rugged, full-coverage or certified drop-proof case. For frequent heavy impacts or demanding outdoor use, consider whether this minimalist design provides the level of coverage you need.

CoolHyper Cooling Technology for Demanding Use

Modern smartphones can warm up during gaming, navigation, video recording, charging and other processor-intensive activities. The AULUMU A18 incorporates its CoolHyper thermal design to help move heat away from the phone through a silicone thermal pad, an aluminum heat sink and a honeycomb ventilation structure.AULUMU describes the updated design as creating a more direct thermal path closer to the phone's processor. The intended benefit is improved heat transfer and slower temperature rise during demanding use, helping make the case a distinctive option for people who frequently use their phones for gaming or navigation.Cooling performance depends on the phone model, workload, ambient temperature, charging conditions and other factors. The case is designed to assist heat dissipation, but it cannot guarantee a particular operating temperature or prevent a phone from heating up.

Aluminum Camera Guard and Raised Edge Protection

The A18 includes a hard-anodized aluminum alloy camera guard designed to help reduce scratches and everyday wear around the camera area. Its raised construction helps keep the camera surround from making direct contact with flat surfaces during ordinary placement.AULUMU also specifies a raised screen edge of approximately 0.5mm. The camera guard is listed as approximately 0.9mm raised, helping reduce direct surface contact when the phone is placed down carefully.These features are intended for everyday scratch and friction protection. They do not make the phone immune to cracks, severe drops or impact damage, and the level of protection depends on how the device is handled.

MagSafe Compatibility for Your Everyday Setup

Built-in magnets help align the AULUMU A18 with compatible MagSafe accessories. This makes it convenient to use a compatible wireless charger, magnetic phone stand, power bank or wallet without removing the case for every attachment.The magnetic system is designed to support a stable attachment experience across compatible accessories. Actual attachment strength, wireless charging performance and accessory fit can vary depending on the accessory and phone model.

• Compatible MagSafe wireless chargers.
• Magnetic desktop and bedside phone stands.
