Temdan Waterproof Case for iPhone 18 Pro Max, IP68 and MagSafe Compatible

A case for everyday carry has different priorities from one designed for wet outings. This Temdan case combines full-body coverage with an IP68 waterproof design for the iPhone 18 Pro Max. Its built-in screen protector and magnetic ring keep key features part of the case, while the translucent matte back adds a subdued look.

Why it makes sense

For pool days, beach trips, or snorkeling, the case is designed for underwater use up to 6.6 feet (2 meters) for 30 minutes. A built-in waterproof membrane helps seal the phone in wet environments, and the touchscreen remains responsive for taking photos while submerged. That makes it a practical choice when you want your phone protected without giving up access to its screen for capturing a moment in the water.

Protection also extends to everyday handling. The full-body design has raised edges around the screen and camera, reinforced corner bumpers, and sealed ports to help shield against scratches, dust, sand, and direct drops. A textured side grip helps the case feel secure in damp hands, while the matte thermoplastic polyurethane back provides a comfortable surface to hold.

The essentials

The case is made specifically for the 6.9-inch iPhone 18 Pro Max, with aligned openings for ports, speakers, microphones, and buttons. The mute switch, volume buttons, and camera button remain accessible, so routine phone use does not require removing the case. Its black, semi-transparent matte back shows the phone while keeping the finish understated.

An embedded magnetic ring supports magnetic accessories such as chargers, wallets, power banks, and car mounts. The case is also described as compatible with MagSafe and wireless charging, so you can keep magnetic accessories in your everyday setup. For sound, open the silicone plug on land to let speaker audio through more clearly, close it before taking the phone underwater to maintain the waterproof seal.

Tips for day-to-day use

Before underwater use, close the silicone sound-port plug to preserve the sealed design. When using the phone on land, open the plug for clearer speaker output. The textured sides are useful for a firmer hold during commutes and outdoor activities, while the raised screen and camera edges add coverage when the phone is set down. For shoppers choosing between a basic everyday cover and a case built for wet environments, this design brings water-use features and full-body protection together.

Before you decide

Which phone does this case fit? It is designed for the 6.9-inch iPhone 18 Pro Max. The button and port openings are aligned for that phone, so confirm the exact phone model before choosing a case.

When it makes sense

It suits you if you want one case for daily handling and water-focused outings, with a built-in screen protector, camera and screen edge coverage, and magnetic accessory support. The iPhone 18 Pro Max-specific fit, adjustable sound port, and underwater-use design make it especially suited to beach days, pool visits, snorkeling, and commutes where a secure grip and all-around coverage matter.
