After power-on, this12V to 5V Buck Module / LED Car Battery Voltage Meter provides real-time detection voltage. When you need to charge phone, iPad, MP3 and other digital products, touch "Output Enable" button and the USB power indicator lights with 5.0V output voltage; when you need to turn off the digital control, touch the "low-power" button, then the module will turn into ultra-low-power standby mode, USB output accordingly shutdown. The 5.0V, 2A of output current capability is enough to meet a variety of USB devices. Besides,voltage is very stable. With wide input voltage, this module can be used for a variety of voltage measurement purposes such as car, battery car, motorcycle, etc.

Features

• Wide range of voltage meter: DC4.5 - 40V
• Output current capability 2.5V/2A (note: the input voltage to a regulated output voltage of 5.0V when the 6.5 - 40V)
• A button ("Output Enable" button) to switch USB output, a key ("low-power" button) to enter the ultra-low power
• Car voltmeter can self-calibration, will never exist without accurate voltmeter problem
• With reverse polarity protection, reverse polarity does not burn
• With over-current, over-temperature protection
