The Mophie 4-in-1 Charging Mat features a multi-coil Qi-inductive array designed for simultaneous power delivery to four devices, including a dedicated mount for an Apple Watch stand. Material analysis identifies a fabric-finish top surface and UL-rated plastic housing. Technical specifications list a proprietary 19V / 4.47A DC input, which provides the necessary power overhead to drive multiple 10W charging zones and an additional 5W USB-A output for legacy devices.
Performance metrics indicate that while the multi-coil design supports varied device placement, efficiency peaks at the center of each coil. Aggregated specification data shows that the unit relies on a Power Management IC (PMIC) to handle 10W, 7.5W, and 5W handshake protocols. Forensic reports suggest the fabric surface can retain heat during peak loads, and the absence of magnetic alignment (MagSafe) requires manual device centering to prevent thermal protection circuits from interrupting the charge cycle.
For users who prefer a single-device, high-fidelity solution with better thermal dissipation, the Belkin 15W pad provides a ventilated base and a certified power adapter.
This multi-device array is classified under smart power as a high-density cable consolidation tool.
