In large-scale commercial furniture projects, “Efficiency” is the metric that defines success. Whether it is a hotel bedside table, a corporate conference desk, or a public marble bench, the time spent on installation, calibration, and maintenance directly impacts the project’s bottom line.
At Shenzhen Honghao Electronic Technology Co., Ltd. (泓浩电子), we don’t believe in a “one-size-fits-all” approach. By mastering the spectrum from 3-12mm embedded modules to 30mm long-distance chargers, we provide tailored solutions that optimize both the manufacturing process and the user experience. This technical guide explores how selecting the right charging distance saves time across the entire product lifecycle.
1: The 3-12mm Embedded Series—Precision for Thin Surfaces
The 3-12mm range is the industry benchmark for standard office and home furniture. Our latest technical revision has optimized the induction coil for an even wider range, starting from 3mm.
1.1 Why 3-12mm is the “Efficiency Champion”
-
Material Versatility: Whether you are working with a thin 3mm wood veneer or a 12mm thick composite board, this module maintains a peak efficiency of ≧80%.
-
Reduced Milling Depth: For thinner tabletops, technicians don’t need to mill deep into the material. This preserves the structural integrity of the furniture and speeds up the CNC routing process by approximately 15%.
-
Thermal Safety: At this distance, the coupling between the charger and the phone is at its strongest, meaning less energy is wasted as heat. This eliminates the need for complex external cooling systems, saving both component costs and assembly time.
2: The 28mm & 30mm Long-Distance Series—Zero-Surface Modification
For premium projects involving thick materials—like solid oak desks or 3cm marble countertops—the 28mm and 30mm series are the ultimate time-savers.
2.1 No Holes, No Damage, No Hassle
The biggest “Time Killer” in furniture manufacturing is surface modification (drilling and edging).
The 28mm & 30mm Advantage: These high-power modules are mounted entirely underneath the surface. You do zero work to the top of the desk.
Labor Efficiency: A team of two can outfit an entire VIP lounge with hidden charging in a few hours, simply by using industrial-grade adhesive or brackets to fix the chargers under existing tables.
Maintenance: Since the surface is untouched, there are no charging “pads” to be scratched, stolen, or damaged by spilled liquids. This reduces long-term maintenance hours to nearly zero.
2.2 Technical Distinction: 28mm vs. 30mm
The 28mm Solution: Optimized for standard thick timber and mid-range stone. It balances high-speed 15W charging with a cost-effective PCBA design.
The 30mm “Distance King”: Specifically engineered with a high-voltage (24V) input and specialized magnetic resonance coils to penetrate heavy granite and quartz. At Shenzhen Honghao, we use 100% pure copper coils to ensure that even at 30mm, the charging speed remains competitive with standard desktop pads.
3: Engineering the “Honghao” PCBA—A Deep Dive into SMT Quality
“How much time is saved when a product doesn’t fail?” This is the question our engineering team answers daily in our SMT (Surface Mount Technology) facility.
3.1 Reliability Through In-House Manufacturing
Unlike trading companies, Honghao controls the PCBA production.
Component Selection: We use automotive-grade capacitors and high-efficiency chips that can handle the power surges of a 30mm induction cycle.
AOI Testing: Every board undergoes Automated Optical Inspection. This ensures that when our 28mm or 3-12mm chargers reach your factory, the “out-of-the-box” failure rate is virtually non-existent, saving you hundreds of hours in quality control and returns.
4: Safety Certifications—Saving Time in Global Logistics
When exporting “Smart Furniture,” the biggest delay isn’t shipping—it’s customs and compliance.
Pre-Certified Solutions: Our 3-12mm, 28mm, and 30mm series are all CE, FCC, RoHS, and PSE certified.
Plug-and-Play Compliance: By providing a certified kit (including the adapter), we save furniture brands the 4-6 months typically required for independent electronic safety testing. You can launch your “Smart Desk” line internationally almost immediately.
5: Summary—Choosing Your Efficiency Path
Choose 3-12mm when you want a visible, high-speed, and ultra-efficient flush-mount design for standard furniture.
Choose 28mm/30mm when you want “Invisible Power” without modifying the expensive tabletop surface, saving massive amounts of labor during installation
Conclusion: Pragmatic Technology for B2B Partners
At Shenzhen Honghao, we don’t just sell chargers; we sell Engineering Confidence. Whether it’s the precision of our 3-12mm series or the raw power of our 30mm long-distance modules, every product is built with one goal: To make your integration faster, safer, and more profitable.
