INJOINIC IP6823 Wireless Charging SoC Found in Three CukTech Products — 7.5W/15W Transmitter Application Roundup
2026-09-08 · Compiled by Best IT Parts from public industry reporting
Teardown investigations by Chongdiantou show INJOINIC's IP6823 Qi wireless charging transmitter SoC has been adopted across three CukTech products: the WPB100P "No. 10 Super Magnetic Power Card" (5,000mAh, 55W bidirectional wired plus 15W wireless output), the TA1406U "No. 15 Super Power Station" desktop charger (up to 140W wired with 15W magnetic and 5W wireless zones), and the CP132ML magnetic power block. The chip integrates dual half-bridge drivers that combine with external N+PMOS transistors into an H-bridge, delivering 5W-15W output under WPC Qi BPP, PPDE and EPP protocols. It also embeds USB PD and DP/DM fast-charge negotiation for 5V/9V/12V input sourcing, ASK demodulation and FSK modulation for Qi communication, plus FOD, NTC temperature sensing and OVP/UVP/OCP protections. Typical standby draw is 10mA (30µA sleep) in a 4x4mm QFN24 package — a compact, high-integration option for magnetic power banks and desktop wireless chargers.
