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.
Advanced Protection: Built-in OVP/OCP/SCP, reverse polarity protection, and thermal shutdown (auto-recovery).
Durable Design: Flame-retardant casing with 50cm heavy-duty cable (18 AWG) for automotive/outdoor use.

Color & Dimensions
Available: Black (RAL 9005)
Dimensions: 65mm(L) × 32mm(W) × 18mm(H)
Weight: 38g

Product Features

Precision Conversion - Maintains stable 5V (±3%) output under load variations
Enhanced Compatibility - Works with standard 12V systems (automotive cigarette lighters, marine batteries, etc.)
