1.8  Do not place the inverter on or near heating vents, radiators or other sources of 

heat or flammable materials.

1.9  Do not place the inverter in direct sunlight. The ideal air temperature for operation 

is between 50° and 80°F.

1.10 Only connect the power inverter to a 12 volt battery or power supply. Do not 

attempt to connect the inverter to any other power source, including an AC power 

source. Connecting to a 6 volt or 16 volt battery will cause damage to the inverter.

1.11 Make sure the AC plug is tight.

1.12 Do not modify the AC receptacle in any way.

1.13 Do not try extending or otherwise changing the 12 volt power cord supplied with 

your inverter. Make sure the cord connections are tight.

1.14 Incorrect operation of your inverter may result in damage and personal injury. 

 The inverter output is 120V AC and can shock or electrocute the 

same as any ordinary household AC wall outlet.

1.15 Do not use the inverter with a product that draws a higher wattage than the 

inverter can provide, as this may cause damage to the inverter and product.

1.16 Do not open – No user serviceable parts inside.

1.17 This device does not include an internal Ground Fault Circuit Interrupter (GFCI).

1.  LED Indicator Light (Green = Power ON)

2.  Standard Electrical 120V AC Outlet

3.  12 Volt Power Plug

4.  USB Power Port

5.  Low-Battery Protection

NOTE: This inverter is designed to be used with a single battery, up to group 31 

type (130 Ah or smaller in size). 
NOTE: Do not use the inverter with a product that draws a higher wattage than the 

inverter can provide, as this may cause damage to the inverter and product.
When you turn on a device or a tool that runs on a motor, the device basically 

goes through two stages:

1.  Start Up – Requiring an initial surge of power (commonly known as the 

“starting or peak load”).

2.  Continuous Operation – Power consumption drops (commonly known as the 

“continuous load”).

The wattage (WATTS) or amperes (AMPS) can normally be found stamped or 

printed on most devices and equipment, or in the user’s manual. Otherwise, 

contact the manufacturer to find out whether the device you want to use is 

compatible with a modified sine wave.
