INKEE CC700 Teardown: Five Identical 140W USB-C Boards Turn a CRPS Server PSU Into a 700W PD3.1 Hub
2026-09-29 · Compiled by Best IT Parts from public industry reporting
The INKEE CC700 Charging Mate is a desktop CRPS adaptor that takes 12V 65A from a standard server supply and exposes five independent USB-C ports, each rated 5V 3A, 9V 3A, 12V 3A, 15V 3A, 20V 5A and 28V 5A for 140W per port and 700W total. The housing measures 23.5cm by 81.1mm by 46.14mm and weighs 311g; the platform recognises the attached module's rating from an 800W unit up to a 1600W CRPS supply. The box ships with five 1.5m braided cables measured at 50V 5A.
Opening the case shows a modular split design with five electrically identical USB-C daughter boards, each carrying its own conversion loop. The port controller is an Injoinic IP2366, an integrated PD3.1 and bidirectional synchronous buck-boost battery-management IC rated to 140W that needs a single inductor and few external parts. It supports 2 to 6 series cells, comes in a 5mm by 5mm QFN40 package with 0.4mm pitch, and adds a 14-bit ADC with I2C telemetry. Each board pairs it with two 04N2R6 MOSFETs in DFN5x6 and two Wayon WMB050N04LG4 40V NMOS devices rated 5.5milliohm in PDFN5060-8L, a CODACA CSBX1265-9R2 9.2uH buck-boost inductor and 100uF 35V filter capacitors.
The main board carries the data path. A WCH CH334P four-port USB2.0 MTT hub in QFN16 with a 12.000MHz crystal links the daughter boards, while a WCH CH32V208CBU6 RISC-V microcontroller with a V4C core at up to 144MHz, 128KB flash, 64KB SRAM, BLE5.3, 16-channel TouchKey and USB2.0 full speed in QFN48 runs from a 32.000MHz crystal to drive the colour display, buzzer and USB communication. A SOP16 touch-detection chip and a synchronous buck converter marked GBJ3C in SOT23-6 complete the control section. Because the five output boards are identical, a single failed port can be serviced without disturbing the other four.
