Struggling to launch a USB-powered rotary shaver that meets Singapore’s strict safety, sustainability, and usability requirements — without in-house engineering or regulatory expertise?
Singapore-Based Brand Launches Magnetic Portable Men’s Shaver with Haohan Electric
A Singapore-based lifestyle brand specializing in compact personal care solutions for urban professionals, RV travelers, and hotel amenity partners approached Haohan Electric in Q4 2025. With no internal hardware development team and limited exposure to PSB certification, packaging compliance under NEA guidelines, or USB-powered motor integration, they faced three critical bottlenecks:
- Technical uncertainty: Could a single-blade rotating system deliver consistent shave performance at ≤120g weight and 5V USB input?
- Regulatory risk: No internal capability to navigate Singapore’s EEESR framework, SINGLAS-accredited lab testing, or bilingual labeling mandates.
- Sustainability execution gap: Needed fully recyclable packaging meeting NEA’s 2025 plastic reduction targets — but lacked supplier alignment on material specs and traceability documentation.
Clear Requirements, Defined Scope
The client requested a commercially viable magnetic portable men’s shaver designed specifically for Singapore’s market conditions:
- USB-C powered (5V/2A input), no AC adapter required — compatible with power banks, hotel USB outlets, and RV systems
- Single-rotary blade head with neodymium magnetic attachment (≥8 N pull force; tested to 10,000+ attachment cycles)
- IPX4-rated housing for bathroom and travel use
- Full compliance with Singapore PSB safety standards (IEC 60335-1 + IEC 60335-2-27), including thermal, electrical, and mechanical stress testing
- Recyclable mono-material PET tray + FSC-certified molded fiber sleeve; zero PVC, zero metallized film
- Batch-level QC documentation: 100% functional test log, 3-point blade runout verification, and full traceability by production lot
Tailored OEM Execution — From Concept to Commercial Shipment
Haohan Electric delivered end-to-end OEM support across R&D, compliance, and supply chain operations — completing the project in 14 weeks from initial inquiry to FBA-ready shipment:
- Co-developed motor control firmware enabling 3-speed USB-stable output (5,000–7,500 RPM) with thermal cut-off at 65°C
- Engineered magnetic docking interface with dual-axis tolerance compensation (±0.15 mm X/Y, ±0.08° angular), validated via 3D-printed prototype iteration and real-user drop testing (1.2 m onto ceramic tile, 50x)
- Secured PSB certification through SINGLAS-accredited lab (Test Report No. SH25-8891); provided full technical file package including circuit diagrams, BOM, and risk assessment per ISO/IEC 17065
- Pre-approved NEA-compliant packaging: 92% post-consumer recycled PET tray + water-based ink printed fiber sleeve; all components labeled with SG recycling symbol (♻️) and material code “PET 1”
- Implemented batch-level quality tracking: Each unit serialized with QR code linking to functional test data, battery cycle count, and assembly timestamp
