FREQUENTLY ASKED QUESTIONS
What issues can cause my mobile power outlet to stop working?
Overheating, incorrect input voltage, and overloading are some basic symptoms. The unit is equipped
with self-protection features that help prevent damage to the mobile power outlet and accessories
being powered by it. There are no replaceable fuses in the mobile power outlet nor do we recommend
or advise opening the unit to repair it. Please follow the proper procedures for resetting the mobile
power outlet which can be found in the owner’s manual for each symptom.
My mobile power outlet does not seem to have the power that I expect from it. Does the age of
the battery or its condition affect the operation of the mobile power outlet?
Yes. Ensure the vehicle battery connections and terminals are free from corrosion and that the battery
is in good working order. If necessary, test the battery to ensure it is producing the proper voltage
level. Clean the terminals with baking soda, water, and a wire brush before connecting the mobile
power outlet to the vehicle battery. Please use all precautions necessary to ensure safety in addition
to wearing rubber gloves and eye protection.
My mobile power outlet is extremely warm during operation. Is this normal?
Under normal operating conditions, the mobile power outlet will be warm but heat should not be
excessive where the case is hot to the touch. If the internal temperature of the mobile power outlet
exceeds its upper limit, the temperature protection feature will engage and the unit will shut off. Allow
the unit to cool, cycle the power switch, and begin using the unit again. Also, do not have the mobile
power outlet in direct sunlight and make sure it is in a well-ventilated area. For adequate performance,
operate the mobile power outlet from 32°F to 104°F (0°C to 40°C).
I plugged a device into my mobile power outlet and it will not power it. The mobile power outlet
began to make a screeching sound and the red LED light is on. What is wrong?
First, test to see if the power source being supplied at the mobile power outlet connection is between
10.5 volts and 14.5 volts (low battery or over-voltage alarm has sounded with red LED light). There
may be adequate voltage coming from the power source but there will be a voltage drop due to the
length and thickness of the wires going to the mobile power outlet connection. If possible, use thicker
gauge wires from the power source to the mobile power outlet or reduce the length of the cables. If
the voltage is not within range, the red FAULT/POWER light will illuminate and the unit will sound an
alarm. The mobile power outlet will have to be reset. Also, it may be necessary to run the vehicle in
order to power the appliance or device upon initial startup and/or during continuous use.
Second, the mobile power outlet may have been overloaded by powering a device requiring more that
the rated power output of the mobile power outlet. Make sure the accessory you are trying to power is
within the rated wattage range of the mobile power outlet (overload alarm has sounded with red LED
light). Use accessories requiring less power. When you turn on some accessories, they may require
two to six times the rated wattage for that appliance or device for startup. If the wattage limitation
is exceeded, the mobile power outlet will not power the accessory. This is known as “peak load,”
“inductive load,” or “starting load.”
There are four power wires and two connections for the positive (+) and negative (–) terminals
on my mobile power outlet. Do I need to use both terminal connections and all four wires?
Yes, connecting the wires using all four terminal connections on the mobile power outlet will ensure
less voltage drop throughout the circuit powering the mobile power outlet from the vehicle’s battery.
Why is the 12-volt accessory plug option only available on some PEAK mobile power outlets?
The 12-volt accessory plug option is available on PEAK mobile power outlets up to 400 watts.
Above this rating, the mobile power outlet’s current draw is higher than what the vehicle’s circuitry is
designed to handle for an accessory plug.
In an effort to extend the run time of the mobile power outlet, is it possible to connect multiple
batteries together?
Yes, but only in a parallel circuit. We recommend you consult the vehicle owner’s manual and the
mobile power outlet instruction manual for proper installation procedures.
