by installing this device in your car, you can easily check the battery voltage in your car using meters. Индикатор напряжения показывает уровень заряда батареи в процентах.
Additionally, the panel has two USB sockets with a total maximum output current of 2.1 A
It does not need an additional power supplyIt is enough to connect the device to the electrical installation, e.g. to the сигаретой lighter socket outputs (preferably in a place for the voltmeter to be activated after turning the ignition key) and the display immediately shows the current battery voltage, the charge indicator and the 5V voltage on the USB outputs.
с этим устройством вы будете знать заранее, когда батарея будет о разрядке.
проверяя статус заряда батареи, вы продляете свою жизнь.
the device is especially useful in the winter.
With the help of a voltmeter, you can keep track of the battery voltage both when the engine is running and when it is turned off.
Only remember to disconnect the device before leaving the car or so that the voltmeter is started after inserting the key into the ignition (leaving the device turned on for a long time may weaken or discharge the battery).
SPECIFICATION:
the range of correct voltages of a car installation:
1. When the engine is running, the voltage should be between:
2. When the engine is turned off and all current consumers are turned off, the voltage should be greater than:
