Bộ chuyển đổi nguồn điện 3000W 12V sang 220V/110V USB kép 12-04 cho xe hơi

3000W 12V To 220V/110V Dual USB Car Power Inverter Converter Modified Wave 12-04 Features: 1. This is a 3000W dual USB power inverter,easy to connect to your vehicle battery. 2. Fault prompt function. In addition to different sound prompts, it can also be displayed more intuitively from the display screen (for example, battery undervoltage, battery overvoltage, overload, high working temperature, output short circuit, etc.). 3. The overload delay closing function is added in the product to solve the sensitive problem of inverter protection when the soluble electrical appliance is started. 4. The small power non professional user market has increased the positive and negative pole return protection function. 5. Intelligent temperature control oil sealing fan. When the inverter is working, it can work at a certain temperature, which is more energy-saving and quieter. 6. Digital MCU control, output wave type, more accurate frequency, accurate output voltage, fast response of protection circuit. Descriptions: Widely used in cars, steamboats, mobile offering post and telecommunications, public security, emergency and other field.
