It is also ideal for use with 12 volt DC cordless/portable/rechargeable DC power supplies and jump-
starter products.
Estimated runtimes below are at 100 watt output:
• Jump-starters with 17-19 amp hour battery
• Compact jump-starter with 15 amp hour battery
• Compact jump-starter with 12 amp hour battery
Lower operating output (less than 100 watts) reduces the current drawn from the DC source, so
longer operating times can be realized.
OPERATION OF INVERTER
1. Insert the unit into the vehicle's (or jump-starter's) accessory outlet.
2. Rotate the plug slightly to make sure there is good contact.
3. A green LED light on the inverter will indicate a proper operation.
4. If the inverter does not work, make sure the ignition/accessory switch is actually powering the
accessory outlet. Some vehicles need the ignition switch turned on.
5. Plug in the AC appliance.
PROTECTIVE FEATURES
The inverter monitors the following conditions:
Low Battery Voltage – this condition is not harmful to the inverter but could damage the power
source, so the inverter automatically shuts down when input voltage drops to 10.6 volts. When this
condition is corrected, the unit will auto-reset.
Over Voltage Protection – the inverter will automatically shut down when the input voltage exceeds
15 volts DC.
Note: The inverter will auto-reset after removing a short circuit. If the inverter's fuse fails,
disconnect the shorter load and replace the fuse inside the inverter. SEE FUSE REPLACEMENT – if
bad fuse is suspected.
OPERATING TIPS
The 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 be between -20°C and 40°C - ideally between 15°C
and 25°C (60 - 80°F). Keep the inverter away from direct sunlight, when possible.
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. The inverter will auto-reset after it cools down.

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.
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. Be sure that the power consumption of the item to be operated is below 100 watts.
If the power consumption is rated in amps, simply multiply by the AC volts (110) to determine the
wattage.
Resistive loads are the easiest for the inverter to run; however, it will not run 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. For safety reasons, the unit will simply shut down if it is overloaded.
To restart the unit, simply remove the load and the unit will auto reset.
Note:
This inverter will not operate appliances and equipment that generate heat, such as
hair dryers, electric blankets, microwave ovens, and toasters.
HOW THIS INVERTER WORKS
This inverter is an electronic device that converts low voltage DC (direct current) electricity from a
battery to 115 volt AC (alternating current) household power. In designing this inverter, the
manufacturer has incorporated design techniques previously employed in computer power
supplies. The result of these design innovations is a smaller, lighter and easier-to-use power
inverter.
The 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 stage is a MOSFET bridge stage
that converts the high voltage DC into 115 volts, 60 Hz AC.
The DC-to-DC converter stage uses creative, high frequency, zero voltage switching power
conversion techniques that replace the bulky transformers found in less technologically advanced
models. The inverter stage uses advanced power MOSFET transistors in a full bridge configuration.
This ensures excellent overload capability and the ability to operate reactive loads like lamp
ballasts and small induction motors.
Inverter Output Waveform
The 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.
The modified sine wave produced by this inverter has an RMS (root mean square) voltage of 115
volts, which is the same as standard household power. 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. These
