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.

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
