About GB40. The NOCO Genius®Boost™ GB40 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 GB40 can instantly jump start most single-

battery applications, up to 20 times on a single charge. The

GB40 is also equipped with a USB battery pack and LED

ﬂashlight, making it the ultimate emergency tool.

Getting Started. The GB40 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

GB40 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 GB40 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.) Connect the HD X Connector to the GB40.

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 ﬂash, 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 GB40 is

ready to jump start your vehicle.

6.) Try starting the vehicle. Most vehicles will

immediately start. Some vehicles may require the

GB40 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 GB40 to rest for ﬁfteen

(15) minutes before attempting to jump start the

vehicle again.

7.) Once you have started your vehicle, disconnect the

battery clamps, and remove the GB40.

Low Voltage Batteries & Manual Override

The GB40 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

GB40 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 1000 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 GB40. 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 GB40 “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 GB40 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 GB40 to rest for

ﬁfteen (15) minutes before attempting to jump start the

vehicle again.

Understanding Charge LEDs.

The GB40 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

25%

Red LED The 25% Charge LED will ‘breath’

on/off while charging and will be solid

Red when the internal battery is 25%

charged.

The 75% Charge LED will ‘breath’ on/

off while charging and will be solid

Yellow when the internal battery is

75% charged.

The 100% Charge LED will ‘breath’

on/off while charging and will be solid

Green when the internal battery is fully

charged.

When connected to a USB charger,

no other charge LEDs will be

illuminated. Once disconnected from

the charger, all four (4) Charge LEDs

will be illuminated when the internal

battery is between 75%-100%, and

the unit is powered “ON”.

Understanding Error Conditions.

The GB40 shall display an Error Condition when a reverse

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

Charging the GB40.

Connect the GB40 using the included USB Charge

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

efﬁcient 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 GB40 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 GB40 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 GB40 will have

various levels of output and runtime. Selecting a lower

power level when using the GB40 for extended periods of

time will prolong battery life.

Modes:

100% > 50% > 10% > SOS > Blink > Strobe > Off

Energy Saving Auto Shut Off.

The GB40 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.
