Features: brand new and high quality Full encapsulation and waterproof design: high-quality imported high thermal conductivity organic silica gel encapsulation technology is adopted, and the interior is fully encapsulated and sealed with thermally conductive epoxy resin, and the for protection level is IP67. Intelligent protection: Built-in intelligent micro-processing chip, 7-fold intelligent for protection system, effective control of overload and heat, make product performance more stable and safe, and effectively protect the equipment and battery life. SMT process: using SMT process, the product volume is reduced, electromagnetic and radio frequency interference is reduced, the defect rate of solder joints is low, the reliability is high, and the anti-vibration ability is strong. Synchronous rectification technology: greatly reduces the rectification loss at the output of the switching power supply, thereby increasing the conversion rate and reducing the current itself. Wide range of applications: suitable for small car models, car driving recorders, navigators, electronic dogs, mobile phones, MP3, MP4 and other electronic equipment with power within 15W. Package Includes: 1x Car Power Converter Specifications: Material: ABS+Alloy Size: As Shown Style: 12V to 3v3A/12v to 3.3v3A/12v to 3.7v3A/12v to 4.2v3A/12v to 5v3A/12v to 6v3A/12v to 7.5v3A/12v to 9v2A Input Voltage: DC-DC8V-22V Output Current: 3A MAX (2A at 9V) Output Power: 9-18W Working Temperature: -40~80 Installation Cable Length: Approx. 13-14cm/5.12-5.51inch note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
