The Xiaomi Smart Jump Rope XMSR-P804 in blue is a versatile fitness tool designed to track your progress through a hidden dot matrix digital display. It utilizes Bluetooth Low Energy 5.0 to sync with Android 8.0 or iOS 12.0 devices, providing detailed weekly, monthly, and annual exercise reports to help you monitor your activity over time. Constructed from durable PC and ABS materials, the device weighs approximately 180g and features handles measuring 162.2 x 25 x 25 mm. You can switch between a traditional 3-meter cord and integrated swinging balls, which allow you to maintain your workout indoors without needing a large open space. Three high-precision Hall sensors ensure your jumps are counted accurately across six different training modes, including options based on calories, repetitions, intervals, or time. The built-in 200mAh battery charges via a Type-C port and lasts up to 20 days if you jump for 30 minutes daily. To get the best experience, the rope length should be adjusted to your height, such as 250cm for someone 150cm tall or 280cm for someone 180cm tall. The package includes the smart rope, a storage pouch, and a user manual.
