Correction: The FCC approval mentioned in this story relates to an updated Apple Watch charger, not the long-awaited AirPower charging mat. The story has been updated to correct the error.

Apple just updated its magnetic Apple Watch charger. Since the physical design looks unchanged, it’s likely that only minor internal tweaks are included in the updated device.

The new device’s model number is MU9F2AM/A, while the old model number was MLDW2AM/A, according to MacRumors.

A Federal Communications Commission document published today granted approval for the new device. It describes the tested unit as “a magnetic charging device which has a single inductive charging coil to charge Apple Watch. The charging frequency is 326.5 kHz, and the maximum power consumption is 5W.”
