NOCO GB20 Genius Boost Sport Lithium Jump Starter Diagram

The NOCO GB20 Boost Sport jump starter provides professional grade performance in a compact and portable design. Rated at 400 amps (4,650 joules) of starting power, it can easily jump start gas engines up to 4 liters. This means it's great for cars, motorcycles, ATVs, UTVs, snowmobiles, personal watercraft, and lawn equipment 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 GB20 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 GB20 Boost Sport Layout Diagram

The GB20 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.


Precision Needle-Nosed Boost Battery Clamps

NOCO GB20 Precision Boost Battery Clamps

The Precision Boost battery clamps included with the GB20 are built to fit tight spaces on powersport equipment and remote battery applications. 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. The cables connect to the GB20 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 GB20 Boost Sport Built-in LED Work Light

From jumping a dead battery to changing a flat tire, the GB20 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 GB20 Boost Sport USB Charging Port

The GB20 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 GB20 Boost Sport 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 GB20 Boost Sport Rapid Charge Technology

The GB20'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 GB20 while on the go by plugging it into a USB compatible 12V port, such as a wall charger or vehicle aux port.


NOCO GB20 Boost Sport Charging Times

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


Rugged Weatherproof Design

NOCO GB20 Rugged IP65 Rated Housing with Port Covers

The GB20 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.

Video Transcript for NOCO Genius Boost Sport Jump Starter Review

Hi everyone, Aidan here with etrailer. Today we're be taking a look at the NOCO Boost Sport. This is gonna be a portable jump starter for your car or other equipment. It's gonna work for gas engines up to four liters and a variety of different battery types and give you a quick and portable solution to get those dead batteries started. Let's check it out. So let's take a quick look at the Boost Sport itself.

This is how it's gonna come right out of the box. You'll notice that we've got a variety of buttons on the front and three different ports, one on the side and two on the back. Now this is going to be the way you charge the box and on the side next to it, that's where you can charge up something like smartphone plugging in the USB out to your device or portable speaker, whatever you got. Now the main thing we're looking at though is going to be that 12 volt out. That's gonna be what we plug our clamps into and use to actually jump our vehicle.

Those are gonna be pretty short but it's a good quality cable. Plugs into that 12 volt out. Make sure it plugs in all the way. It's a firm connection. And that'll give us our positive and negative clamps color coded for easy identification and this will be the part that we connect to our battery.

Now, to use this they recommend charging it up to full battery first. They include a charger cable to make that happen because it does come only partially charged. We're not gonna actually be jumping any batteries today 'cause our battery's not dead. So we'll leave it at that. And to begin the jump starting process plug in to those battery clamps and make sure that you've got that full charge.

With the NOCO Boost off and your vehicle off, clamp onto the positive and then the negative terminal on your battery. Once connected, you can hit the power button to turn the unit on. All the LEDs will flash to let us know that they're working and then this white boost LED will illuminate. Now for whatever reason, if we had our clamps hooked up in reverse, then this error light would be illuminated solid red and if the battery was too hot it would be flashing. But since this white boost LED is illuminated, at that point, you could start your vehicle. Now depending on how this all goes, if your car doesn't immediately start up, then you can retry again. You may need to just leave this connected for up to 30 seconds before you try turning your car on. If that still doesn't work, you can retry. Just make sure that you wait about 15 minutes in between each jump cycle and don't exceed five consecutive jump attempts within that 15 minute window. That's just to make sure that nothing overheats and everything stays protected. And when disconnecting it when you're all done, disconnect the clamps in the reverse order. So negative first, then positive. These clamps are gonna have spark protection and nice covers over the top of them so you don't have to worry about that too much. Still be careful of it. Just make sure that you treat them with care and then you can remove the unit from your engine bay. Now a couple other things. If that white LED didn't illuminate when you we're connected to the battery, it might be because your battery is too low. If it's below two volts then you're gonna need to manually override. You can press and hold the red button here to just manually override that and feed that jump into your battery because if your battery is too dead then it just won't be able to detect it and it won't illuminate that white boost LED. The last button on the unit is a light bulb. You probably saw that before but that's just to activate an LED light. So if you needed a small flashlight it's got multiple power levels and then it's got a couple different strobing features. So if you're maybe stuck on the side of the road and you needed some extra assistance and needed to get someone's attention then the strobe could do that. The internal lithium ion battery has a 24 watt hour capacity. Now what that translates to in real world use is gonna be 20 jump starts off a single charge. And the ability, again, like we told you before to charge things like your phone in the case of an emergency. It's gonna hold a charge for a little over a year with minimal discharge. But if you do need to recharge it, you can use that included cable to plug into maybe a USB in your car, plug into the USB in using that micro USB and you can charge it in as little as three hours. Now if it's partially charged, it'll be quicker than that but it's good that you can do it in the car, at the house, in the garage, wherever you need it. And in the case of your devices you just plug into that other USB the USB A port where it says USB out. Get that lined up, make sure it's facing the right way and then you can plug the other end into your phone or device. So we'll grab that, grab my phone and show that that is working as well so long as we have the unit actually on. And there we go. Charging now. With all of these dust caps on, it does have an IP65 rating. So if you're out in the rain and the elements, as long as you open these up when you're under the hood protected from the rain, it shouldn't damage anything and it should hold up pretty well over time. And the nice thing about it is how small it is. It does come with a small bag for storage, plenty of room for the box itself, as well as any of the accessories like the alligator clamps and that small USB charging cable. And when you're done with that, the whole bag is still pretty small and compact making it easy to pull that drawstring tight, store it somewhere like your center console. Mine's a little bit full right now, but if you make a bit of room, stores there in your glove box under your seat wherever you need it to fit until it's ready to be used again. And a couple other things. If you ever needed replacement clamps, you could get those here at etrailer. But NOCO also offers ring terminals. So if you wanted to install that permanently on the battery side, have a lead just hanging out in your engine bay ready to go it makes the hookup process quicker because then all you need to do, plug it in turn the unit on and get to jumping. So if you've got a vehicle that frequently sits for long periods of time that you need to jump maybe after the winter to get it ready for the summer then you can do that. It just makes the whole process easier. But this has just been our quick look at the NOCO Boost Sport Jump box. Thanks for watching.

Great product. Would buy again if nece ssary.



by:

These hold a charge for months. Have used to charge devices like phones, speakers and flashlights and start my truck when “someone” left the interior light on for a week!



by:

Have had this for over a year. Takes up very little space in my car. My battery died while out of town this summer, used it to jump start my car, drove straight to an auto supply store, got a new battery - no muss, no fuss. I have AAA but this was so much easier than waiting for them to show up.



by:

Work great!I've used them a couple times! A must have in every vehicle!



by:

Noah E ordered me the correct parts that I needed Thanks Noah E



by:

NOCO is a quality known Brand. etrailer delivered the item in a Very timely Manner. The video's really are informative. Thanks



by:

One of the battery clamps came apart within about 2 months (perhaps used twice). The springs in the clamps appear to be too strong for the copper clamps (the riveted ends came apart). Was too difficult to file a claim so I just purchased another set of cables. The unit seems to work well when I need it but the clamps definitely need some tweeking.



by:

Thought I should have one as we travel a lot and tow a car trailer. A week after I got it a car battery died. Jump started instantly with the NOCO and twice more without recharging the NOCO before I got the car to the shop. Very solid wires and clamps, simple to use and recharges quickly.



by:

I had to use it once this year and it did the job to start my car after the battery charge went low overnight.



by:

Best booster I’ve ever owned
Bought
this because friends have the smaller ones and they work great and I’m sick of carrying a big jump pack around. I’ve jumped diesel pickups along with farm equipment. So I put it to the test and tried it on an old
CAT D6 bad it worked plus only used two bars of power
Only complaint is how long it takes to charge



by:

I bought four of them so all of my adult children would have one. Mine has saved me twice starts both my 6 cylinder SUVs.



by:

Fantastic product. Easy to use. Very powerful battery.



by:

Don’t know yet haven’t had the chance to use it.



by:

I have not had to use it very much, but when I have it has started my battery and other's that I have helped also. Lightweight and easy to use. Handy USB connection to charge, but I have had mine in the pickup for 6 months and it was still charged and still jumped a dead battery. I do not think you should leave it that long without charging, but I guess it shows how well this device works!



by:

Great service



by:

Have had my NOCO boost pro for a year now. Has not failed me yet. I've had to use it probably 6 times while at work and it has performed flawlessly. It holds a charge well and I store it in a case in my vehicle unless temps go below 20 and I bring it inside. I would highly recommend having one. Thanks etrailer!



by:

Have not had the chance to use yet it does seem to have some quality about it i also purchased the GBCOO7 cable I have no issues with jump starter at this time but I don’t like the plug cover for the cable it doesn’t seem to stay in place



by:

Order shipped quickly and packaging was in excellent shape. Very happy with my purchase. We are looking forward to using this to save the weight and time associated with a battery test pack and double as a jump starter.



by:

GREAT COMPANY! GREAT PRODUCTS! AWESOME SHIPPING!



by:

Outfitting my UTV for mountain trips. Gonna need this for back up!



by:

THIS IS A VERY ROBUST JUMP STARTER. I PLAN TO USE IT IN MY SHOP AS MY GO TO JUMP STARTER.



by:

Just used it again last week. Holds charge great. Super easy to charge and use. Easy to carry with you in the vehicle. When jumping the dead vehicles start right away. Great product great price. Would positively recommend this product and the order delivery process with etrailer.



by:

From what I see it’s a product
But I
haven’t charged or use tested it , just arrived so
I have not been disappointed yet by etrailer
If ever the opportunity I would like to become a product tester
Best regards



by:

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.



by:

Absolutely great customer service. Called on Wednesday to order the product and had it delivered on Friday. Customer service emailed to verify delivery and everything. Thank you so much for being professional and courteous.
