With the rise of outdoor sports such as mountain climbing, rock climbing, cliff rappelling, river tracing, and adventure, outdoor three-proof mobile phones, namely waterproof, drop-proof, dust-proof mobile phones, have ushered in new development opportunities. Shenzhen Kangkaisite Communication Equipment Co., Ltd., which has been cultivating in the field of outdoor mobile phones for many years, recently said that its professional outdoor mobile phone CONQUEST currently accounts for about 35% of the global market. "Of the ten mobile phones, three and a half are produced by us. Our annual volume is about 2 million units. Based on this, the global annual shipment volume is about 6 million units. We think this volume is extremely high. Big imagination. " CONQUEST recently launched the latest S16 outdoor flagship phone in Shenzhen. This is the brand's new product after the S12 was launched one year ago. The chief technology officer of CONQUEST told reporters that the development of three-proof mobile phones is different from ordinary mobile phones. Three-proof mobile phones need some processing in the layout of ordinary mobile phones, so the development time is relatively long. "The other is the test version. We have to do a lot of cruel environmental testing, and it will definitely take longer than others, so the entire development cycle is relatively long. Generally, we maintain two to three products a year," Chief Technology Officer said. According to reports, the newly launched CONQUEST S16 is thinner and lighter than the previous generation. It also has the ability to resist low and high temperatures while maintaining excellent three-proof performance. In the low temperature environment of -35 ℃, S16 can continue to work. According to the official introduction, in cold weather areas, you only need to bring a pair of 1.5mm thick gloves and turn on the "glove mode" to continue using. In response to the shortcomings of satellite phones currently on the market, such as thick, large, heavy, inconvenient to carry and low configuration, the Chief Technology Officer said that CONQUEST launched the S18 Tiantong satellite rugged mobile phone with a built-in 9000mAh battery, making outdoor adventure and travel more calm. At the same time, CONQUEST and China Telecom jointly launched a dedicated Tiantong satellite SIM card. The ordinary satellite phone's tariff is 6-7 yuan / minute, while the current charge of the CONQUEST S18 Tiantong satellite rugged mobile phone is 1.6 yuan / minute. It is understood that the CONQUEST S18 Tiantong satellite rugged mobile phone has been sold in JD.com and Taobao flagship stores.
