The “Waterproof smartphone pouch with air pump” is a high-performance waterproof pouch for smartphones developed by Pleasant.japan Inc., utilizing the technological expertise cultivated since its founding in 2016. Its most notable feature is the air pump system, which has obtained a U.S. patent. This system allows the air inside the pouch to be expelled with a single push, adhering the smartphone closely to the case, thereby significantly improving the operability issues that were a challenge with conventional waterproof cases. The transparent part is made of lightweight and durable TPU material, while the body is made of polyester, ensuring safe use in outdoor and waterside activities. The waterproof performance complies with the international standard IPX8, and the double sealing structure with a zipper and hook-and-loop fastener effectively prevents water intrusion. It accommodates a wide range of smartphones up to 6.8 inches, with the development concept focusing on “balancing protection and functionality,” emphasizing the protection of smartphone touch operations and camera shooting without compromise. While other products are limited to a single sealing method or specific compatible models, this product achieves differentiation through proprietary technology and high-quality management. It is appreciated for its ability to safely protect smartphones without compromising convenience in various scenes such as outdoors, sports, and bathrooms.
