Mophie Powerstation Hub Teardown Review: All in One
The Powerstation Hub by tech accessory maker Mophie is quite similar to the Anker PowerCore Fusion we reviewed earlier. It is a USB-C and USB-A wall charger that doubles as a portable battery, but also has the added benefit of featuring a Qi charging surface. And here's our teardown.
It is a black rounded square with a two-tone matte-and-glossy finish.
From top to bottom: USB-C bi-directional input and output port, two USB-A output ports, LED indicators, and power button.
The larger part of the case is covered with anti-slip silicon pads.
Input: 100V-240V，50/60Hz，0.25A. Input (USB-C PD): 5V2.4A, 9V2A, 12V1.5A. Total output: 18W. Qi wireless charging: 5W. Output: (USB-C PD): 5V2.4A, 9V2A, 12V1.5A. Output: (USB-A QC): 5V2.4A, 9V2A, 12V1.5A. Output: (USB-A): 5V2.4A. Battery: 3.6V, 6100mAh, 21.96Wh.
Interchangeable adaptor with foldable prongs.
It is also a power bank with 6100mAh capacity.
The thickness is 29.5mm/1.16inch.
It weights 259.7g/9.16oz.
Dimensions: 84 x 84 x 29.5mm. It is slightly bigger than the Apple 87W PD charger for MacBook Pro 15.

The Injoinic IP6528 is a buck converter with integrated synchronous switch, and an SoC that supports USB-C multi-protocol dual-port output. It supports dual port detection, single port fast charging output, dual port intelligent recognition 5V output, and can provide up to 45W output power. It also has line compensation function, as well as input overvoltage protection, undervoltage protection, output overcurrent protection, overvoltage protection, undervoltage protection, short circuit protection and other functions. It provides an all-rounded solution for applications including car chargers, power adapters, and smart sockets.

The controller chip for the power bank function also comes from Injoinic, model IP5328P. Thanks to its high integration with fewer components needed, the IP5328P is very suitable for PCB designs which require small footprint. The Injoinic IP5328P also integrates the QC2.0/QC2.0/QC 3.0 input/output fast charge protocol, and passed the QC3.0 Qualcomm certification with certificate number 4780056908-2. FCP, AFC, SFCP, MTK PE, USB C DRP, BC1.2 input/output charging protocols are all supported. It is worth mentioning that the IP5328P not only supports PD3.0/2.0 fast charging, but also PPS (Programmable Power Supply) at 5~12V.

The controller chip for power bank function is a Injoinic IP5306. The IP5306 is a multi-function power management SoC with integrated boost converter, lithium battery charge management, and battery level indication. It requires only one inductor for buck and boost functions. The synchronous boost system provides up to 2.4A of output current with conversion efficiency as high as 91%. It automatically enters sleep state when no load is present, and the quiescent current is reduced to 50uA. The chip requires fewer peripheral compnents, which can effectively reduce the size of the overall solution and reduce the BOM cost.
