LL-5587+7510LDJ
67W 2C1A GaN Fast charging solution With Zero standby power & Smart display
Product Overview
The LL-5587+7510LDJ 67W 2C1A Zero Standby Power Fast Charging Solution solves a long-standing industry challenge—standby power consumption. By achieving an ultra-low standby power of <5mW, it not only complies with IEC62301 and ErP 7 standards but also significantly reduces energy waste, setting a new benchmark for efficiency.
Leveraging next-generation GaN (Gallium Nitride) technology, this solution delivers high efficiency in a compact form factor with improved thermal performance. Its 2C+1A multi-port design intelligently distributes power, supporting fast charging for multiple devices simultaneously, while broad protocol compatibility—including PD3.2 AVS for iPhone 17, PPS, QC, and SCP—ensures it works seamlessly with everything from laptops to smartphones.
What truly sets this solution apart is its integration of a smart display, offering real-time charging status for a modern, user-centric experience. As an exclusive, production-ready solution, we provide the only offering on the market that combines zero standby power, multi-port fast charging, and an integrated display in a mature, customizable package, backed by our full technical support to accelerate your time to market.

<5mW Standby Power – Tested & Verified
Traditional chargers continue drawing power even when not in use—wasting electricity 24/7. Our zero standby power solution cuts this waste by over 95%, reducing standby consumption from typical 75-150mW to <5mW.
That means your product stops consuming energy the moment devices are unplugged, eliminates phantom energy waste—delivering measurable savings for users and the planet.
For users, this means lower electricity bills and a smaller carbon footprint—automatically, every single day.
Reliability Testing
Voltage Stress Test (Primary & Secondary)
Ripple & Noise Test (<30Mv)
Our 67W 2C1A solution delivers a peak efficiency of 93.4% at 230Vac—exceeding global energy standards including US DoE Level VI and EU CoC Tier 2. Unlike conventional designs that optimize only at specific loads, our GaN-based architecture maintains >90% efficiency across the entire load range (10%–100%), ensuring minimal energy loss whether charging a smartwatch or a laptop.
Engineered for the unexpected.
We don't just design for ideal conditions—we test for the extremes:
- Voltage stress testing 264Vac ensures safe operation even in unstable grid conditions
- Full-load burn-in validates long-term stability
- Wide temperature range testing guarantees performance from cold winters to hot summers
When you choose our solution, you're choosing proven reliability.
Smooth Power = Safe Charging
High ripple & noise can damage sensitive electronics and reduce battery life. Our solution ensures:
- ✅ Battery-friendly charging – Ultra-low ripple protects device batteries
- ✅ Stable performance – Clean power means no unexpected shutdowns
- ✅ Full compliance – Meets strict international standards
Peak ripple & noise: <30mV across all conditions.
