USING THE SCHUMACHER EC-4000-USB EMERGENCY
CAR STARTER AS A 12V DC POWER SOURCE
The Emergency Car Starter has a 12V DC accessory outlet located
behind the right cap. This port has a positive center terminal. Most
12V DC accessories have this conguration. Do not use the ac-
cessory if it does not have a positive center pin. NEVER plug the
Emergency Car Starter’s male adaptor plug into the 12V accessory
outlet on the right side of the Emergency Car Starter.
USING THE EMERGENCY CAR STARTER AS A USB
POWER SOURCE
The Emergency Car Starter has a 5V DC USB power outlet located
on the back of the case. This USB outlet can power devices that
require less than 500mA of power. NEVER plug this USB outlet
directly into a computer USB outlet or damage to both devices
could result.
To activate the USB power port, depress the CHARGE CAR BAT-
TERY switch on the front of the unit. When nished using the USB
power port, press the CHARGE CAR BATTERY switch to the OFF
position (button up) before storing the EC-4000-USB.
STARTING A VEHICLE WITH A WEAK BATTERY:
Important: Turn your ignition key, lights, radio, etc., to OFF posi-
tion before connecting the Emergency Car Starter, as it will drain
the EC-4000-USB’s power:
1. With the CHARGE CAR BATTERY button in the OFF position
(button up), connect the EC-4000-USB’s male plug to the
vehicle’s 12V DC accessory outlet.
