Your eFUEL switching DC Power Supply is designed to use household AC power source to power
equipments that required DC power. The eFUEL converts standard household power 100-240V AC to 12-
18V DC power and can supply up to 30 amperes of continuous power.

* Two DC power outputs, up to 30 amperes
* Output voltage adjustable 12-18V
* Large LCD indicates voltage and current amperes output
* Two USB ports, 5 volts, 1000mA total for MP3 player, mobile phone and digital cameras
* Smart cooling fan
* Over temperature protection
* Over loading protection
* Short circuit protection



Caution: Make all other connections before you connect the power supply to standard AC power

Turn the sleeves of the red and black binding output posts counterclockwise to expose the wire hole.
Insert the device's positive wire (usually red) into the red binding post's wire hole, then tighten the
binding post's sleeve to secure the wire in place.
Insert the device's negative wire (usually black) into the black binding post's wire hole, then tightening
the binding post's sleeve to secure the wire in place.
If you are using the banana plugs connection, insert the plugs into the terminal's jack.

Warnings: To avoid damage to both the power supply and the device:

Follow the correct polarity when connecting the power supply and the device.
Do not let the ends of the positive and negative wires touch each other.





To use the power supply after you connect the device to it, set POWER to turn it on with the power switch.
Please check all connections and confirm the wall AC outlet has power before you switch on the power

If the outlet has power, set POWER to OFF, reduce the load (by using a device that does not require
more than 30 amps), then set POWER to ON. Your power supply's overload protection circuit
automatically shuts down the power supply when it is overload and resets by turning POWER to OFF.

Caution: Place your power supply in a well ventilated open and cool area. Do not block the openings at
the fan suction on the side and the discharge openings on the other side.

Caution: To reduce the risk of energy hazard, be careful not to short the output terminal during operation.
Remove the output connections after use.

Caution: Your power supply might cause TV or radio interference even when it is operating properly. To
determine whether your power supply is causing the interference, turn off your power supply. If the
interference goes away, your power supply is causing it.

Try to eliminate the interference by:

Moving your power supply away from the receiver.
Connecting your power supply to an outlet that is on a different electrical circuit from the receiver.
Contacting a qualified service technician forhelp.
