Xiaomi claimed earlier today that its new 5.99-inch Mi Mix 2S phone has better features than the iPhone X. Now, it has another piece of hardware to boast about: a 99 yuan (about $15 USD) wireless charging mat, as spotted by AndroidCentral.

The Mi Mix 2S is the first Xiaomi phone to offer wireless charging, and at today’s launch event, Xiaomi revealed a wireless charging mat designed especially for the phone. The mat supports the Qi spec with a maximum charge of 7.5W. Xiaomi says the Mi Mix 2S takes three hours to get a full charge from the mat.

The maximum charge of 7.5W is lower than other wireless chargers currently available on the market, like Samsung’s 9W Fast Charge Wireless Charging Stand or the 10W Anker Powerport. But that’s to be expected, given that other wireless chargers on average cost between $40 to $50.

There’s no word yet on if the mat will be released outside of China.
