ATTENTIONS
Extreme Weather Storage: The GT-TRUCK can be stored safely in
temperatures ranging from -22°F (-30°C) to +140°F (60°C). Note that
while it is safe to store the device in these temperatures, room
temperature (+72°F (+21°C)) is considered optimal operating range. If
at all possible, we recommend bringing the GT-TRUCK to room
temperature before using for maximum effectiveness.
Cold Weather Operation: Cold weather makes jump starting much
more difficult, as not only do batteries lose their effectiveness but
turning over your engine is tougher due to stiff belts, thicker oil, etc.
To optimize starting, we recommend bringing your GT-TRUCK to room
temperature before boosting. If this is not possible, you may find that
the first attempt at jump starting will produce a weak output (turn
over slow or maybe not at all). This is normal as when a battery is cold,
output is reduced. One advantage of lithium batteries is that they
warm up fast from use. After each attempt wait at least 30 seconds to
allow the battery to warm up sufficiently before attempting next
boost, and do not crank for more than 5 seconds per time.
Discharge Rate: With the GT-TRUCK powered off and stored, the
typical discharge rate is 2-3% per month. Meaning after 6 months, you
should still have at least three bars of charge, assuming it was left at
100%. This is enough to boost your vehicle in most conditions,
however, to be safe, we recommend charging the GT-TRUCK back to
100% every 3 months to ensure maximum power when you need it.

JUMP STARTING A VEHICLE
Step 4: Once the vehicle is running, remove the red
positive "+" clamp and the the black negative "-"
clamp (in that order) from the battery of the vehicle
being boosted.
Step 3: Start your vehicle as normal using your key or
by pushing the start button, if so equipped. If your
vehicle fails to start or you see a red light and or
beeping, please refer to the next page for
trouble shooting.
Step 2: Connect the red clamp to the vehicles
positive "+" battery terminal or boost point and the
black clamp to the vehicles negative "-" battery
terminal or boost point. If you are unsure of where
these are located, please consult your vehicles
owners manual. After connecting the clamps
successfully the “Start Light” should be solid green,
this means power is flowing and it is safe to move
to Step 3. If the light is not solid green, please refer to
the troubleshooting guide on the next page.
Step 1: Make sure your GT-TRUCK has at least 75%
(three bars) charge before boosting, we recommend
a full charge for larger engines. The higher the
charge level, the more available boosting power.
7
JUMP STARTING A VEHICLE
It is possible to jump start most vehicles when the GT-TRUCK
has a charge below 75% , but a more powerful boost is available
at higher charge levels. We recommend boosting with a charge
level as close to 100% as possible.
Most engines should start in less than 3 seconds. Do not crank
for more than 5 seconds continuously as you may cause
damage or overheating to the GT-TRUCK
TIPS & TRICKS
Trouble shooting: Explanation of lights and alerts
GREEN LIGHT ON - Good connection and the
circuit is working. You may attempt to start the
vehicle at this point.
GREEN LIGHT BLINKING - The vehicle battery
is low. Press the BOOST button. When the light
illuminates a steady green, start the vehicle
within 30 seconds.

JUMP STARTING A VEHICLE
TIPS & TRICKS CONT’D
In cold weather or for vehicles that are more difficult to start
(older, in poor mechanical shape, vehicles that have been
sitting for extended periods, etc.) it may be necessary to make
a few start attempts. Crank the vehicle for no more than 5
seconds at a time and allow the jump starter to cool off for at
least 60 seconds between attempts. If the vehicle fails to start
after 5 attempts, we recommend using an alternate method to
get the vehicle going or consulting a mechanic.
To maximize the power available to start your engine, please
ensure to shut off all accessories not required to start the
vehicle such as heaters, heated seats, radios, lights and any
other electronics. Doing so will ensure all the power is directed
to where it is needed, starting the vehicle.
The SUPERSAFE features are designed to minimize the risk
of boosting a vehicle, but please note that it is impossible to
eliminate all risk. Using the "Boost” feature means that power is
flowing once the green light is solid. It is important you are
aware and willing to accept the risks that come with this.

CHARGING USB DEVICES
Step 2: Plug the other end of your USB charging
cable into the device in need of charging.
QUICK
PRESS
TIPS & TRICKS
Be sure to use a quality charging cable that is compatible and
recommended for use by the manufacturer of the device you
are charging for optimal results.
The output level from the USB ports can vary depending on the
type of cable being used and the requirements of the device
being charged.
Step 3: For charging with the USB Type-A port, please
quick press the power button to initiate charging.
INPUT OUTPUT
Step 1: The GT-TRUCK has two USB ports
including one High Speed USB Type-A port (Blue
port) and one 2.4A USB Type-A port (White port).
Plug your USB charging cable into one of the
ports as required
11
DC OUTPUT
Step 1: Open the rubber cover on port labeled as
“DC POWER OUTLET" and plug your 12V device in.
TIPS & TRICKS
Be sure to check the power draw of the device you are trying to
power as this port is limited to a 10A draw. Anything above that
will cause power to be disabled to the port.
The DC port is an output port used to power car products，
NOT a charging port
The DC Output port is designed to provide mobile power to 12V
devices such as air compressors, GPS units and more. The
port is rated for max output of 12V/10A. As with any battery,
the output voltage varies based on the charge level.

Step 2: Plug the other end of the USB charging
cable into any appropriate USB charging port (Type-
A or Type-C).
Step 1: Plug the USB Type-C end of the
included charging cable into the GT-TRUCK.
TIPS & TRICKS
The GT-TRUCK is designed to prevent overcharging, however it
is best to unplug the charger once the charge level reaches
100%.
It is best to charge the GT-TRUCK at room temperature.
Allowing the GT-TRUCK to cool down after jump starting or warm
up if it is in freezing conditions before charging will prolong and
prevent damage to the internal battery.
The GT-TRUCK features an 18W max USB Type-C input charging
port. This gives the GT-TRUCK the flexibility to be charged with
any compatible USB Type-C charging cable using most USB
Type-A or Type-C ports on the market. Please note, however,
that the power output from USB ports can vary significantly
which will affect total charge times. A full charge should take
approximately 10.5 hours but will vary based on the type of
charged used.
CHARGING THE GT-TRUCK
INPUT OUTPUT
It is important not to leave the GT-TRUCK completely
discharged (one bar) for extended periods, as this could cause
irreversible harm to the lithium battery in the GT-TRUCK.
