NOCO GB40 Genius Boost Plus Lithium Jump Starter Diagram

The NOCO GB40 Boost+ jump starter provides professional grade performance in a compact and portable design. Rated at 1,000 amps (7,000 joules) of starting power, it can easily jump start gas engines up to 6 liters, or diesel engines up to 3 liters. This means it's great for cars, trucks, boats, motorcycles and ATVs with single battery systems. The rechargeable lithium-ion battery provides up to 20 jump starts per charge. A built-in LED work light and charging port for USB devices make it a great addition to any roadside emergency or safety kit.

How to Jump Start Your Car Using A Lithium Jump Starter Diagram

The GB40 removes the frustration of having to find or wait for someone to give you a jump. Just attach the clamps to the vehicle's battery terminals, turn the unit on, and start your engine. It's that simple.

User-Friendly Interface with LED Indicators

NOCO GB40 Boost Plus Layout Diagram

The GB40 was designed to provide a simple, user-friendly experience. Back-lit LED indicators let you verify that the unit is operating correctly, and they allow it to be easily operated at night. These indicators signal the unit's charge status and alert you to potential performance issues or errors. This allows you to identify if the unit is too hot or cold for operation or detect a reversed polarity connection to a battery.

The touch-button interface allows you to turn the unit on or off or activate the LED work light at the push of a button. The manual override feature can be selected to jump start a deeply discharged battery, below 2-volts. It is important to remember that when this mode is activated, the unit's safety features will be disabled.

Heavy-Duty Boost Battery Clamps

NOCO GB40 Boost Battery Clamps

The Boost battery clamps included with the GB40 are built to handle the toughest conditions. Unlike typical, plastic battery clamps, the Boost clamps are constructed entirely of metal, ensuring maximum conductivity. The clamps are covered with an over-molded plastic housing, which makes them easy to operate even with work gloves on. And the durable 8 AWG silicone cables remain flexible in cold weather so you won't struggle while positioning the clamps.

High-tension springs in the clamps let them tightly grip top and side post battery terminals, and prevent them from slipping during use. And the clamps' large teeth provide a strong connection to the terminals.

The cables connect to the GB40 by plugging them into the available Boost connector port. A protective cover ensures the connection point stays protected when the cables are disconnected from the unit.

High-Intensity LED Work Light with 6 Settings

NOCO GB40 Boost Plus Built-in LED Work Light

From jumping a dead battery to changing a flat tire, the GB40 has you covered. The unit has integrated LEDs, with 3 brightness settings, which can be used as a work light in low-light conditions. It can also function as an emergency beacon. Just choose a flash pattern, SOS, blink, or strobe, and then set the unit behind your vehicle to increase visibility and safety.

Portable Charging Power for USB Devices

NOCO GB40 Boost Plus USB Charging Port

The GB40 also doubles as a portable power source. The unit has a USB port, which make it easy to charge a smartphone, tablet, camera, wireless headphones, or other device. This is great when you're in an area where power may not be readily available, like a campsite.

NOCO GB40 Boost Plus USB Device Charging Times Diagram

The table above provides a quick reference for how many times you can recharge your USB devices before the unit itself needs to be recharged.

Quickly Recharge from USB Power Sources

NOCO GB40 Boost Plus Rapid Charge Technology

The GB40's lithium-ion battery can be recharged from 0 to 100-percent in as little as 3 hours, from a USB power source rated at 2-amps. You can easily charge the GB40 while on the go with the included USB car charger that plugs into a vehicle's aux port, or cigarette lighter socket.

NOCO GB40 Boost Plus Charging Times

The Boost Plus can be charged from any USB-powered port, like a wall charger or laptop, but can take up to 12 hours to completely charge based on the amp rating of the connection.

Rugged Weatherproof Design

NOCO GB40 Rugged IP65 Rated Housing with Port Covers

The GB40 comes with rubber covers that seal the connection points to protect the unit from dirt, dust, and water. With the ports closed the unit has an IP65 rating, which means it can withstand multi-directional, low-pressure water jets and is completely sealed against solid particles like dust or sand.

The housing is made from tough lexan resin that protects the internal electronics against impacts. The unit can handle being dropped, kicked over, and just about anything else the work day brings with it.

Great. Holds charge for a long time.

I have used my NOCO to start my truck and my Ford Tractor. The tractor was out in the brush and very difficult to get to with jumper cables. The NOCO paid for itself with the tractor because I didn't need to have a service call. You hope you don't need it often but when you do, it is a life saver. For a hundred bucks one should be standard equipment in every new car.


Not working right; who do I send it to to be fixed?


Bought this to carry in my boat. It’s light and does take up much room. I haven’t had to use it yet.


Delivered as promised. Charged up and waiting to go for jump starting toad behind my class c rv.

Have been an etrailer customer for years. As usual, my order arrived in a very timely manner. I have carried a lead acid battery type of emergency jump battery in my car for years. I purchased one for my adult daughter but, she does not carry it in her car because of it's size (she always has things in the trunk) not to mention she never remembers to charge it. I had one of the lead acid types corrode and leak acid inside the unit and ruin it. This time I purchased two of the Noco 1000A GB40 units, one for me and one for my daughter. Because of it's much smaller size, lithium battery, power output and ability to hold a charge for longer periods. maybe she will keep it in her car.


I've owned this unit for a full year now and used it several times. Like all of these things you have to read the actual directions, which I failed to do the first time. The unit and the boost function work great. I've jumped super dead cars, and larger trucks with it with no issues at all. The unit feels like a quality build and has a nice case. Another superb product from etrailer.


Watched my friend jump start his outboard motor with this NOCO charger. Also had ports to charge cell phone for weeks. With this hurricanes plowing through, invaluable...if power goes out.


Work great. Hold a charge for months. Have used for charging devices and to start my suv.


Have not used it yet but glad I can carry it in my car or boat and know I have something to start my car in and emergency


I like the size of the unit but cannot honestly say how it works as I haven't had to use it yet. I'm hoping it still has power if n when I do need it.


It is greatI have used several times an works great. No complains.
