Why KingARC
What Makes Our Solutions Different
Chip-Level R&D
Founded in 2016, KingARC designs its own wireless charging and fast-charge technology — the engineering runs deeper than assembly.
120W Full Compatibility
Fast chargers and cables handle Apple, Huawei, Xiaomi and more, across PD, QC, PPS, SCP and FCP, up to 120W.
Wireless, Done Right
Phone, car and Qi2 magnetic charging with stable thermal control, foreign-object detection and reliable alignment.
Full-Process Support
From design and firmware to testing and mass production, we support your project end to end as a technical partner.
Quality Control
Quality You Can Trace to Every Batch
Every production batch goes through testing, inspection and documentation — because reliable products are built on systematic processes, not luck.
- 1
Incoming Inspection (IQC)
Chips, coils, connectors and materials are checked on arrival; non-conforming lots are quarantined before assembly.
- 2
In-Process Control (IPQC)
First-piece confirmation and in-line audits during every batch keep assembly consistent.
- 3
100% Functional Test
Every unit is tested for charging output, protocol handshake and protection behavior — no sampling on safety.
- 4
Aging & Reliability
Units run under load to surface early failures inside the factory, not in your customers' hands.
- 5
Outgoing QC (OQC)
Appearance check, AQL sampling and per-batch records keep every shipment fully traceable.
Documentation that protects your brand
- Batch-level test reports with serial numbers
- Pre-shipment QC inspection records
- Certification compliance tracking (CE / FCC / RoHS)
- Real-time production line photos on request
