USING THE USB PORT
The USB port provides up to 2A at 5V DC.
1. Plug the device into the USB port.
2. Turn the USB device on.
3. Reverse these steps when finished using the USB port.
4. Reverse these steps when finished using the USB port.
The converter draws power, even when the switch is OFF.
To avoid battery drain, disconnect the converter when not in use.
7. POWER SOURCE
Your average automobile or marine battery at full charge will provide an
ample power supply to the converter for approximately 3 hours when the
engine is off. The actual length of time the converter will function depends
on the age and condition of the battery and the power demand being placed
by the device being operated with the converter.
If you decide to use the converter while the engine is off, we recommend
you turn OFF the device plugged into the converter before starting the
engine. To maintain battery power, start the engine every 2 to 3 hours and
let it run for approximately 10 minutes to recharge the battery.
Although it is not necessary to disconnect the converter when turning over
the engine, it may briefly cease to operate as the battery voltage decreases.
While the converter draws very low amperage when not in use, it should be
unplugged to avoid battery drain.
8. HOW POWER CONVERTERS WORK
There are two stages involved in converting 12 volt DC (battery) power into
120 volt AC (household voltage):
STAGE 1: The power converter uses a DC to DC transformer to increase the
12-volt DC input voltage from the power source to 145 volt DC.
STAGE 2: The converter then converts the 145 volt DC into 120 volts AC
(household voltage) using advanced MOSFET transistors in a full bridge
configuration. A “modified sine wave” waveform is generated by this
conversion.
