The Amber Valley Power Protector makes flat batteries a thing of the past!
The Power Protector constantly monitors the battery voltage and warns if it drops below a certain level. Warning is either by speech alarm or buzzer alarm.
If the vehicle's ignition is on, the Power Protector will constantly warn the driver, without automatically disconnecting all circuits passed through it.
If the ignition is off, the Power Protector will automatically disconnect all circuits passed through it after 1 minute from the warning.
