Meizu's PANDAER WP07 is a foldable three-in-one wireless charger built around a compact burger-like form factor. It unfolds to power a phone, a smartwatch and wireless earbuds at once, with the magnetic pad rated to 15W. The unit ships with a USB-C to USB-C cable and a manual.

Nameplate data lists USB-C input of 5V/3A, 9V/3A and 12V/2.5A. Outputs are a 15W magnetic pad, a 5W base pad and a 2.5W watch pad, for 22.5W maximum total. Measured dimensions put the main body at about 61.09mm across and 29.92mm thick when folded, with the two charging modules at roughly 12.47mm and 17.54mm; the whole unit weighs about 96.9g.

POWER-Z KM003C testing recorded a 0.54W idle draw and about 18.77W (8.73V/2.15A) into an iPhone 17 Pro Max. Charging a phone and earbuds together pushed input to roughly 21.31W (8.70V/2.45A).

Inside, the magnetic coil uses Litz wire over a flux-guard sheet with a magnetic positioning ring. The main board carries the wireless transmitter, buck-boost conversion, power MOSFETs and resonant-capacitor switching, alongside NPO resonant capacitors and a power inductor.

Voltage conversion is handled by a Southchip SC8724 synchronous four-switch buck-boost converter that integrates four power MOSFETs. It accepts 2.7-22V input and delivers 3-22V output with up to 10A average inductor current, with switching frequency configurable across 250kHz, 500kHz, 800kHz and 1MHz in a 25-pin 4x4mm QFN.

Power stages use Vergiga VS3622DE dual NMOS devices rated 30V and 10mOhm in PDFN3333, driven at 5V logic. The watch module relies on a GeoforceChip GWW6025 wireless power transmitter SoC in FC-QFN25 that combines a 32-bit MCU with a 15mOhm full bridge, FSK modulation and ASK demodulation.
