Geely's Galaxy TT reserves a powered stud connector on top of the dashboard so accessories can be mounted without suction cups or extra wiring. The magnetic wireless charging phone holder attaches directly to that connector and combines an 18N magnetic clamp with up to 15W wireless charging and a ball-joint mount for angle adjustment.

The holder carries model number XW0011, rated at 15W maximum wireless output with a DC 9V-16V, 2A maximum input. The charging module measures about 62.79mm in diameter and 11.99mm thick, and the complete holder weighs roughly 111.0g. Printed safety data lists an operating range of -10 to 45 degrees C, a 0.3kg maximum load while driving and 7kg when parked.

The teardown identifies an MTQ5820 wireless power transmitter chip in a QFN48L package as the core of the module. The part is stated to comply with the WPC Qi V2.2 specification and to support BPP, EPP and MPP modes alongside USB PD, QC and UFCS protocols. It accepts 4V to 24V input and can deliver up to 80W, and it holds AEC-Q100 Grade 1 automotive certification.

Around the controller the board carries an SC8120 buck converter in a QFN32 package and a JMTQ130P04A load-switch MOSFET rated -40V with 9mohm on-resistance, along with 30N40 wireless power MOSFETs. The charging coil uses litz wire and is surrounded by an arc-segmented N52 magnet ring, with NPO resonant capacitors on the board.
