About GB70. The NOCO Genius®Boost™ GB70 is an
ultra-compact and portable lithium-ion jump starter for high-
displacement gas and diesel engines in cars, trucks, boats
and more. Safe to use on engines of any size. It’s extremely
safe for anyone to use. It features spark proof technology
and reverse polarity protection. The GB70 can instantly
jump start most single-battery applications, up to 40 times
on a single charge. The GB70 is also equipped with a USB
battery pack, 12V OUT port and LED flashlight, making it
the ultimate emergency tool.
Getting Started. The GB70 comes partially charged
out of the box and needs to be fully charged prior to use.
Carefully read and understand the vehicle owner’s manual
on specific precautions and recommended methods for
jump starting the vehicle. Make sure to determine the
voltage and chemistry of the battery by referring to your
battery owner’s manual prior to using this product. The
GB70 is for jump starting 12-volt lead-acid batteries only.
Connecting to the Battery.
Before connecting to the battery, verify that you have a 12-
volt lead-acid battery. The GB70 is not suitable for any other
type of battery. Identify the correct polarity of the battery
terminals on the battery. The positive battery terminal is
typically marked by these letters or symbol (POS,P,+).
The negative battery terminal is typically marked by these
letters or symbol (NEG,N,-). Do not make any connections
to the carburetor, fuel lines, or thin, sheet metal parts. The
below instructions are for a negative ground system (most
common). If your vehicle is a positive ground system (very
uncommon), follow the below instructions in reverse order.
1.) Connect the positive (red) HD battery clamp to the
positive (POS,P,+) battery terminal.

2.) Connect the negative (black) HD battery clamp
to the negative (NEG,N,-) battery terminal or vehicle
chassis.
3.) When disconnecting, disconnect in the reverse
sequence, removing the negative first (or positive first
for positive ground systems).
Jump Starting.
1.) Verify the voltage and chemistry of the battery.
2.) Confirm the HD battery clamps are connected to
the correct polarity battery terminals.
3.) Make sure all of the vehicle’s power loads
(headlights, radio, air conditioning, etc.) are turned off
before attempting to jump start the vehicle.
4.) Press the Power Button to begin jump starting. All
LEDs will flash, indicating that all LEDs are properly
functioning. If you are properly connected to the
battery, the White Boost LED will illuminate and the
charge level LEDs will chase. If the battery clamps are
connected in reverse, the Red Error LED will illuminate.
Reverse the connections to clear this error and then
the White Boost LED will illuminate. The White Boost
LED is illuminated, when the GB70 is ready to jump
start your vehicle.
5.) Try starting the vehicle. Most vehicles will
immediately start. Some vehicles may require the
GB70 to be connected for up to 30 seconds before
starting. If the vehicle does not start right away, wait
20-30 seconds and try again. Do not attempt more
than five (5) consecutive jump starts within a fifteen
(15) minute period. Allow the GB70 to rest for fifteen
(15) minutes before attempting to jump start the
vehicle again.
6.) Once you have started your vehicle, disconnect the
battery clamps, and remove the GB70.
Low Voltage Batteries & Manual Override
The GB70 is designed to jump start 12-volt lead-acid
batteries down to 2-volts. If your battery is below 2-volts,
the Boost LED will be “Off”. This is an indication that the
GB70 can not detect a battery.
If you need to jump start a battery below 2-volts there is a
Manual Override feature, which allows you to force “On” the
jump start function.
CAUTION. USE THIS MODE WITH EXTREME CARE. THIS
MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY.
BOTH THE SPARK PROOF AND REVERSE POLARITY
PROTECTION FEATURES ARE DISABLED. PAY VERY
CLOSE ATTENTION TO THE POLARITY OF THE BATTERY
BEFORE USING THIS MODE. DO NOT ALLOW THE
POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH
OR CONNECT TO EACH OTHER AS THE PRODUCT
WILL GENERATE SPARKS. THIS MODE USES VERY
HIGH CURRENT (UP TO 2000 AMPS) THAT CAN CAUSE
SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF
YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT
ATTEMPT AND SEEK PROFESSIONAL HELP.
Before using the Manual Override feature, make sure the
HD battery clamps are connected to the correct polarity
battery terminals. To use the Manual Override feature, press
and hold the Manual Override Button (a red exclamation
point icon inside a red circle) for three (3) seconds. The
White Boost LED will flash “On” and “Off” indicating you
have successfully entered into Manual Override and it is
ready to jump start your vehicle. If connected in reverse
polarity, the Red Error LED will illuminate and the unit will
not operate.
CAUTION: POWER THE GB70 “OFF” BEFORE
DISCONNECTING THE BATTERY CLAMPS. THIS WILL
ENSURE YOUR SAFETY. REMEMBER BOTH THE
SPARK PROOF AND REVERSE POLARITY PROTECTION
FEATURES ARE DISABLED.
Most vehicles will immediately start. Some vehicles may
require the GB70 to be connected for up to 30 seconds
before starting. If the vehicle does not start right away,
wait 20-30 seconds and try again. Do not attempt
more than five (5) consecutive jump starts within a
fifteen (15) minute period. Allow the GB70 to rest for
fifteen (15) minutes before attempting to jump start the
vehicle again.
Understanding Charge LEDs.
The GB70 has four (4) Charge LEDs - 25%, 50%, 75%
and 100%. These Charge LEDs indicate the internal
battery’s state-of-charge (SOC). See below:
LED Explanation
The above charge states apply when the GB70 is NOT
connected to a power supply and recharging.

polarity condition is present, a battery below two (2) volts,
or the internal battery overheating. When one of these Error
Conditions are present, the following will happen:
LED Explanation

the USB OUT port and connect to your USB device.
The number of times you can recharge a USB device will
vary between devices. For recharge times, contact your
device manufacturer.
Powering Your 12V Devices.
Connect the 12V Cable to the “12V OUT” port on the
GB70, and the other end to the Female 12V Plug (12V AUX/
Cigarette Lighter Port.) Plug-in any standard 12V device (Up
to 15A) with a 12V plug and turn the GB70 “On” to start
powering your device.
LED Flashlight.
The GB70 has an integrated ultra-bright LED flashlight. It
has seven (7) light modes that effect its performance and
longevity: 100%, 50%, 10%, SOS, Blink, Strobe, and Off.
To turn the flashlight “On” and “Off”, use the Power button
with the light bulb icon. Press once to turn the flashlight
“On” at 100% luminosity, again for 50% luminosity (within
3 seconds), again for 10% luminosity (within 3 seconds),
again for SOS (within 3 seconds), again for Blink (within 3
seconds), again for Strobe (within 3 seconds) and again
for “Off”. If a light mode is not selected within 3 seconds,
it will remain “On” in the current light mode, and the next
selection will turn the flashlight “Off”.
Depending on the mode selection, the GB70 will have
various levels of output and runtime. Selecting a lower
power level when using the GB70 for extended periods of
time will prolong battery life.
Modes:
100% > 50% > 10% > SOS > Blink > Strobe > Off
