About GB30. The NOCO Genius®Boost™ GB30 is
an ultra-compact and portable lithium-ion jump starter
for cars, boats, motorcycles, ATVs, lawn mowers, RVs,
tractors, trucks and more. It’s extremely safe for anyone to
use. It features spark proof technology and reverse polarity
protection. The GB30 can instantly jump start most single-
battery applications, up to 20 times on a single charge. The
GB30 is also equipped with a USB battery pack and LED
ashlight, making it the ultimate emergency tool.
Getting Started. The GB30 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 specic 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
GB30 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 GB30 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

Mailing Address:
negative (NEG,N,-) battery terminal or vehicle chassis.
3.) When disconnecting, disconnect in the reverse
sequence, removing the negative rst (or positive rst
for positive ground systems).
Jump Starting.
1.) Verify the voltage and chemistry of the battery.
2.) Conrm the HD battery clamps are connected to
the correct polarity battery terminals.
3.) Connect the HD X Connector to the GB30.
4.) Make sure all of the vehicle’s power loads
(headlights, radio, air conditioning, etc.) are turned off
before attempting to jump start the vehicle.
5.) Press the Power Button to begin jump starting. All
LEDs will ash, indicating that all LEDs are properly
functioning. If you are properly connected to the
battery, the White Boost LED will illuminate. 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 GB30 is
ready to jump start your vehicle.
6.) Try starting the vehicle. Most vehicles will
immediately start. Some vehicles may require the
GB30 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 ve (5) consecutive jump starts within a fteen
(15) minute period. Allow the GB30 to rest for fteen
(15) minutes before attempting to jump start the
vehicle again.
7.) Once you have started your vehicle, disconnect the
battery clamps, and remove the GB30.
Low Voltage Batteries & Manual Override
The GB30 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
GB30 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 400 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 and the HD X Connect is connected to
the GB30. 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 ash “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 GB30 “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 GB30 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 ve (5) consecutive jump starts within a
fteen (15) minute period. Allow the GB30 to rest for
fteen (15) minutes before attempting to jump start the
vehicle again.
Understanding Charge LEDs.
The GB30 has four (4) Charge LEDs - 25%, 50%, 75%
and 100%. These Charge LEDs indicate the internal
battery’s state-of-charge (SOC). See below:

Cable to the USB IN port and the USB car charger. It
can also be recharged from any USB powered port,
like an AC adapter, car charger, laptop and more. The
USB IN port is rated at 2.1 Amps to ensure safe and
efcient charging of the internal lithium battery. Due to
FCC regulations, we recommend not to charge and
discharge the unit at the same time.
Charging Times.
The time to recharge a GB30 will differ based on the
discharge level and the power source used. Actual
results may vary due to battery conditions.
Charging Your USB Devices.
You can recharge virtually any USB device, like a
smartphone. Connect the included USB Charge Cable
to the USB OUT port and connect to your USB device.

LED Flashlight.
The GB30 has an integrated ultra-bright LED ashlight. It
has seven (7) light modes that effect its performance and
longevity: 100%, 50%, 10%, SOS, Blink, Strobe, and Off.
To turn the ashlight “On” and “Off”, use the Power button
with the light bulb icon. Press once to turn the ashlight
“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 ashlight “Off”.
Depending on the mode selection, the GB30 will have
various levels of output and runtime. Selecting a lower
power level when using the GB30 for extended periods of
time will prolong battery life.
Modes:
100% > 50% > 10% > SOS > Blink > Strobe > Off
Energy Saving Auto Shut Off.
The GB30 has a built in energy saving feature that will
automatically turn the unit off after seven (7) hours. To
continue using, simply power on the unit again.
