In addition it includes a 12 volt 2.4 amp USB output ideal for using and charging tablets, smart phones and many other USB powered devices. The unit also features a digital display that illustrates the vehicle's battery voltage and device connected current consumption in watts on a large led display. The inverter incorporates all the protection circuitry for the unit and the device connected to it. The inverter also supports a remote on/off panel switch (sold separately) for an out of the way installation. The voltage from your inverter is a little different than the voltage in your home. The voltage in your home is called a “sine wave”, while the voltage from the inverter is a “modified sine wave”. Because of this difference, you will need a meter that measures “true RMS” voltage. If your meter does not measure “true RMS”, then it will read low. If it does not say “true RMS” on the front of your meter, then it is not a true RMS meter and it will read low.
