HOW THIS INVERTER WORKS

This inverter is an electronic device that converts low voltage DC (direct current) electricity from a battery to 110/120 Volt AC (alternating current) household power. In designing this inverter, we have incorporated design techniques previously employed in computer power supplies. This result of these design innovations is a smaller, lighter and easier-to-use power inverter. The All-in-one mobile power inverter converts power in two stages. The first stage is a DC-to-DC conversion process that raises the low voltage DC at the inverter input to 145 volts DC. The second is a MOFSFET bridge stage that converts the high voltage DC into 110/120 volts, 60 Hz AC.

All-in-one mobile power inverter Output Waveform

This AC output waveform of this inverter is known as a modified sine wave. It is a stepped waveform that has characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads, including linear and switching power supplies used in electronic equipment, transformers, and small motors.

145 volts peak 115 volts RMS

The modified sine wave produced

by your inverter

All-in-One

The modified sine wave produced by this inverter has an RMS (root mean square) voltage of 110/120 volts. Most AC voltmeters (both digital and analog) are sensitive to the average value of the waveform rather than the RMS value. They are calibrated for RMS voltage under the assumption that the waveform measured will be a pure sine wave. Non-TRUE RMS meters will read about 20 to 30 volts low when measuring the output of this inverter. For accurate measurement of the output voltage of this unit, use a TRUE RMS reading voltmeter such as a Fluke 87, Fluke 8080A, Beckman 4410 or Triplett 4200.

ALWAYS TURN THE INVERTER ON BEFORE APPLYING POWER TO THE DEVICE.

The standard North American 110/120 volt AC and USB outlets allow the user to operate multiple devices simultaneously. Simply plug the equipment into the unit.

Note: Ensure wattage of all equipment simultaneously plugged into the power inverter does not exceed 120watts continuous.

Rated Versus Actual Current Draw of Equipment

Most electrical tools, appliances, electronic devices and audio/visual equipment have labels that indicate the power consumption in amps or watts. B e sure the power consumption of the item to be operated is below 120watts. If the power consumption is rated in amps AC, simply multiply by the AC volts (110/120) to determine the power. Resistive loads are the easiest for the inverter to run; however, it will not operate larger resistive loads (such as electric stoves and heaters), which require far more wattage than the inverter can deliver. Inductive loads (such as TVs and stereos) require more current to operate than do resistive

loads of the same wattage rating.

All-in-One

For safety reasons, the inverter will simply shut down if it is overloaded. To restart the unit, simply reinsert the12-Volt

vehicle accessory adapter to reset.

Operation of the 110/120 Volt AC Outlet

1.Connect the Power Cord to the inverter.

2.Connect either the 12-Volt DC Vehicle Accessory Adapter or the 12-Volt DC Airplane Adapter to the end of the 12 Volt Power Cord.

3.Insert the selected adapter Plug into a vehicle's (or other 12-Volt DC power source's) DC accessory outlet or airplane DC power outlet.

4.Rotate the vehicle accessory plug slightly to make sure there is good contact.

5.The LED in the inverter will light GREEN, indicating a proper connection.

6.If the inverter does not work, make sure the ignition/ accessory switch is actually powering the accessory outlet. Some vehicles require the ignition switch to be turned on.

7.Plug the (110/120 Volt AC) appliance into the inverter's two or three-prong AC outlet and operate normally.

Note: The inverter will not operate appliances and equipment that generate heat, such as hair dryers, electric blankets, microwave ovens and toasters.

Operation of the USB Power Port

1.Connect the Power Cord to the inverter.

2.Connect either the 12-Volt DC Vehicle Accessory Adapter or 12-Volt DC Airplane Adapter to the end of the 12-Volt Power Cord.

All-in-One

3.Insert the selected adapter plug into a vehicle's (or jump starter's) DC accessory outlet or airplane DC power outlet.

4.Rotate the plug slightly to make sure there is good contact.

5.The LED will light GREEN, indicating a proper connection.

6.If the inverter does not work, make sure the ignition/ accessory switch is actually powering the accessory outlet. Some vehicles require the ignition switch to be turned on.

7.Plug the USB-powered device into the inverter's USB Power Port and operate normally.

Notes:This inverter's USB Power Port does not support data communication. It only provides 5 volts/500mA DC power to an external USB-powered device. The USB power output is not controlled by the ON/OFF Power. The USB power is always on when the Power Cord is connected to a 12-Volt DC power source. Remember to disconnect the Power Cord from any power source when the unit is not in use.

Protective Features

The inverter monitors the following conditions:

• Low Battery Voltage-This condition is harmful to the inverter, and could damage the power source, so the inverter will automatically shut down when input voltage drops below 10.5 Volts DC.

• Input Voltage Too High-The inverter will automatically shut down when DC input voltage exceeds 15 Volts, as this can harm the unit.

• Thermal Shutdown Protection-The inverter will auto- matically shut down when the unit becomes overheated.

• Overload/Short Circuit Protection-The inverter will auto- matically shut down if a short circuit occurs.

• AC Ground Leakage-The inverter will automatically shut down when leakage current exceeds a preset safety level.

Operating Tips

The All-in-one mobile power inverter should only be operated in locations that are:

• DRY-Do not allow water or other liquids to come into contact with the inverter.

• COOL-Surrounding air temperature should ideally be 0-40°C (32-104°F). Keep the inverter away from direct sunlight, when possible.

• WELL-VENTILATED-Keep the area surrounding the inverter clear to ensure free air circulation around the unit. Do not place items on or over the inverter during operation. The unit will shut down if the internal temperature gets too hot.

• SAFE-Do not use the inverter near flammable materials or in any locations that may accumulate flammable fumes or gases. This is an electrical appliance that can briefly spark when electrical connections are made or broken.

TROUBLESHOOTING

Common Audio/Visual Problems Problem: Buzzing Sound In Audio Systems

Some inexpensive stereo systems and boom boxes make a buzzing sound when operated from the inverter, because the power supply in the electronic device does not properly filter the modified sine wave produced by the inverter. The only solution to this problem is to use a sound system that has a higher quality power supply.

The All-in-one mobile power inverter is shielded to minimize interference with TV signals. However, in some instances, some interference may still be visible, especially when the TV signal is weak. Try the following to improve the picture:

1.Move the 120 Watt Inverter as far away as possible from the TV set, the antenna, and the antenna cables. Use a short AC extension cord, if necessary.

2.Adjust the orientation of the antenna cables, and the TV power cord to minimize interference.

3.Make sure that the antenna feeding the TV provides an adequate (snow-free) signal and that high quality,

shielded antenna cable is used.

Fault LED Lights/Alert Buzzer Sounds

When the Power/Fault LED turns from GREEN (indicating the unit is powered) to RED, a fault condition is present and the unit will automatically shut down shortly. See "Protective Features" on page 9 and "Common Power Output Problems" below.
