USING THE POWER SOURCE

See Figures 1 - 2.

When a charged battery pack is installed, this power source 

converts DC electricity to 120V AC household power and/or 

USB-A (5/9/12V, up to 3A) or USB-C (5/9/12/20V, up to 2A) 

charging power, allowing the user to charge and power a variety 

of devices. 

WARNING:

Risk of electric shock.

 When using a grounded appliance 

this tool will not provide an electrical path to earth ground. 

Do not power devices with damaged or frayed power cords.

  Insert a battery pack into the power source.

  Press the power button (   ) to turn the power source on. The 

LED will light up green when ready to use.

  Plug devices you want to power or charge into the power 

source’s USB ports and/or 120 volt receptacle.

 

 

If the power button LED blinks red, the power source may 

be overloaded. Disconnect your device, make sure your 

battery pack is sufficiently charged to power your device, 

then press the button to reset the power source. Reconnect 

your device and try again. If the fault condition immediately 

reoccurs, the item being powered exceeds the capacity of 

the power source.

 

 

If the power button LED turns solid red, the power source is 

overheated. Allow the unit to cool until the LED blinks red, 

then press the button to reset the power source.

 

 

If the power button LED blinks yellow, the battery pack is 

low and needs to be recharged.
