Product Introduction This professional-grade DC voltage converter efficiently transforms 12V power sources to stable 5V output, ideal for charging mobile devices in automotive/marine/industrial environments. Features precision voltage regulation and multiple built-in protections.
Key Specs
Voltage Step-Down Technology: Converts 12V DC input to stable 5V/3A output (±3% precision) for fast charging smartphones, tablets, and low-power devices.
Universal Compatibility: Micro-USB output supports Android phones, Bluetooth devices, cameras, and more (5V/2.4A default, QC 2.0 optional).
Wide Input Range: Works with 12V systems (cars, boats, solar panels) – accepts 9-24V DC input for flexible use.
Enhanced Compatibility - Works with standard 12V systems (automotive cigarette lighters, marine batteries, etc.)
Durable Construction - Flame-retardant casing with strain relief joints
Intelligent Protection - Auto-shutdown for overload/short-circuit scenarios
Universal Fitment - Compact design for confined spaces
Compatibility Designed for devices requiring Micro-USB charging: • Mobile phones • GPS units • Dash cams • Portable speakers • Electronic measurement tools
Applications
Car Charging: Power Android phones, dash cams, or GPS devices via 12V car outlets.
Outdoor Adventures: Charge devices from 12V batteries, solar panels, or RV power systems.
DIY Electronics: Prototype 5V circuits, Arduino projects, or Raspberry Pi accessories.
Emergency Kits: Reliable backup power for portable speakers, drones, or medical devices.
Safety Compliance • Meets international electrical safety requirements • Passed 5,000V AC withstand voltage test • 100% Hi-pot tested • ROHS-compliant materials
Why Choose This Converter?
Plug-and-Play Simplicity: Direct 12V-to-USB conversion – no wiring or configuration needed.
Fast Charging Support: Optional QC 2.0 delivers 9V/12V for compatible devices (select model).
Rugged Build: Weather-resistant casing and shielded cable for harsh environments.
Multi-Device Protection: Safeguards against voltage spikes and short circuits.
Certifications & Standards
Safety: CE, FCC Part 15B, ISO 7637-2 (vehicle EMC)
Environmental: RoHS, REACH
Warranty: 12-month warranty (excludes physical damage or liquid exposure). Note:
Confirm device compatibility – Micro-USB only. For USB-C, use an adapter (sold separately).
Max output: 5V/3A (15W). QC 2.0 requires 12V input and compatible devices.
Critical Safety Warnings
Do not submerge or expose to rain – non-IP rated.
Check input polarity – reverse connection may damage the converter.
Disconnect during vehicle ignition to avoid voltage surges.
Power Anywhere – Step Down 12V to 5V with Uncompromised Safety!
Optional Configurations:
USB-C Output: Replace Micro-USB with USB-C female (+$8).
QC 3.0 Upgrade: Add Quick Charge 3.0 support (+$12).
Extended 2M Cable: Heavy-duty 16AWG cable for off-grid setups (+$15).
Compatible with 12V DC systems. Not for industrial equipment, HVAC systems, or loads exceeding 15W.
