At long last, Xiaomi opens up for business in the US and Europe (but it isn’t selling smartphones)

• Mi Band, an activity and sleep tracker that retails for $15. Compare that to Fitbit’s tracking wristbands, which begin at $100.
• Mi Headphones are $80 headphones that come with over-the-ear and on-ear cushions. Without trying them on, it’s hard to say what their closest competitor is, but over-the-ear headphones regularly start at $100 with high-end versions going for several (or many) times that.
• 10400mAh Mi Power Bank ($14), a portable battery pack, has enough charge to power the iPhone 5S four and a half times. Mophie, one of the better-known brands in this space, sells its powerstation XL, which has a capacity of 12000mAh, for $130.
• 5000mAh ($19) Mi Power Bank can charge the iPhone 5S more than two times over. Mophie’s lower-capacity powerstation plus, which holds 3000mAh of power, retails for $80.

Xiaomi, which has become China’s largest smartphone vendor in its short five-year history, sees accessories as the next growth frontier. Aside from its expansion to the US and Europe, the company recently debuted a slew of new products in China, including a $16 scale that tracks weight and body mass index, an $800 55-inch 4K television set, and an $8 power strip designed for mobile devices.
