Established in Shenzhen in 2015, Paiyi Power Technology Co., Ltd. began as a power supply trading enterprise. We expanded our business and built our own manufacturing base in Huizhou, Guangdong in 2019.
Today, we run a 2,000 m² standardized factory with 50 staff members, focusing on the R&D and production of 20W–300W power adapters. We deliver reliable, cost-effective power supply solutions for industrial, commercial and automation applications worldwide.
Our engineering direction is led by the founder, who spent his earlier career as R&D director at Shenzhen Meikai Electronics. That background is why power architecture, magnetics and EMC design stay in-house at Paiyi Power rather than being outsourced.
Our OEM Experience — We have developed OEM/ODM power programs for a number of well-known European and American consumer brands — including Legrand, HKC, Belkin and Hama — producing GaN chargers and power adapters built to strict EU and US compliance standards. Working to these requirements has shaped our quality-control process and our ability to handle complex custom requirements.

SMT Capability Behind Our Power Programs
High-power custom power supplies depend on the upstream chain, not only on the final assembly floor. This is the SMT factory Paiyi Power holds a stake in — a Tier-1 placement partner.
- Fuji NXT / M3S placement modulesModular high-speed placement on the partner line our programmes run on — the fine-pitch, high-pin-count boards a multi-port high-power design needs.
- Boards come back to our own floorPCBA is inspected on arrival in Huizhou, then assembled, ATE-tested and aged under our own process. Every unit ships after 100% inspection.
- Why it matters for high powerThermal layout, creepage and clearance are decided at placement. Working through the same partner instead of a broker is how those decisions stay under control.

Brands We Have Developed Power Programs For
PY-DC-GaN-140W — 140W GaN Charger (2C1A)
A shipped, certified example of our high-power GaN ODM platform: full-speed PD 3.1 EPR on a single port plus two extra devices, in a compact 2C1A body.
Why it stands out
- Full-speed laptop + 2 more devices. USB-C1 delivers the complete 140W (28V/5A) to a 16″ laptop, while USB-C2 and USB-A keep a phone and earbuds charging at the same time — something a single-port 140W brick cannot do.
- Compact for a true 2C1A 140W unit. 78×77×30 mm / 0.35 kg (~180 cm³), smaller than comparable 2C1A 140W chargers.
- Up to 93.25% efficiency at 28V/5A (single-port, 100% load); EU ErP (Reg. 2019/1782) compliant.
- Universal protocols: USB PD 3.1 / PD 3.0 / PPS / QC — MacBook, iPad, iPhone, Galaxy, Steam Deck.
- Certified safe: IEC 62368-1 (CB Scheme) + CE + RoHS + ErP, with OVP / OCP / OTP / SCP and CB-tested fault auto-shutdown.
86.58Wh Portable Power Station → OEM Reference Design
A shipped example of our OEM work: this 86.58Wh portable power station was engineered and brought to mass production by us for an outdoor-power brand, and is selling really well on Amazon across the dash cam and camping categories.
- Developed as a complete unit. System design, electronics and final assembly handled in our Huizhou plant, from concept to mass production.
- Certified and fully protected. FCC, CE and RoHS certification arranged before mass production, with over-current, over-voltage, short-circuit and temperature protection built in.
- Sized for real use. 86.58Wh keeps a dash cam running through the night, recharges in about four hours over USB-C PD, and stays under the 100Wh airline limit.
- Higher power, same team. We develop, design and produce higher-output outdoor power stations for projects that need more than this 86.58Wh class.
