Is this capable of starting up a v8? And i don’t mean the tomato juice…:)

I guess i’m the outlier here, my b7 rs4’s battery died the other day because i’m an idiot and left the parking lights on while checking them. First attempt i left it on a good 10-15 seconds before attempting to start, i got one crank attempt out of the jump pack and it was fully charged, almost started, but it sucked the jump pack dry in that one attempt…recharged the jump pack and had another go, got it started with half jump pack left with only 1 attempt. Maybe it’s the high compression ratio of that 4.2, maybe it was all 20 million computers that were also trying to fire up…maybe with my bad luck i have a bad jump pack, idk, but that was my experience using it on a v8. I wouldn’t even think of trying to start my 6.5 detroit diesel with it, lol….

How long does the charge for the jumper last. Dead batteries are few and far in between. If i were to charge it will it last a year, 2 years?

Mine lasted 6 years, in fairness it did not get charged up periodically. I bought it in 2016, it now won’t take a charge anymore.
But, i used it 7 or 8 times in those 6 years (vintage cars) and it saved my butt each time.
For $100 i feel like that’s a fair trade. It lasted about as long as i expected. I will probably buy another

Will this start a gel battery?

I found this on the noco faq page….
What types of batteries can boost jump?
All boost models (except the gb500 boost max) can jump start 12v lead acid batteries only. This includes wet, gel, maintenance free, enhanced flooded battery, and absorbent glass mat batteries. The gb500 boost max is capable of jump starting 12v and 24v acid batteries.

What is the operating temperature range? Can it be safely left in the hot car in the middle of summer (180 degrees or more)?

There is good information that the upper storage temperature of 104°f (40°c) is the limit. My lithium jump starter (types) states this 104° number in its manual and googling provides backup for this temperature limit. My vehicle gets above 150° f when setting in my driveway in the s. Calif summer as determined by my optical thermometer. It is also known fact that keeping a lithium battery fully charged reduces its ability to withstand higher temperatures.

Allowed as carry-on luggage during flights?

Yes. The gb40 is faa compliant and can be taken on a plane, however they have to be in your carry-on. No-lithium batteries are allowed to be checked in luggage.the gb40 is under 100wh which is the limit set by the faa. For more additional information, or for current updates, please see the link below to the faa guidelines. Https://

How long to charge?

Initially you need to charge it for about 24 hours. After the initial charge you can use several times before you need to charge it.
Why did this person charge the gb40 24 hours? After it is fully charged you should have 2 red one yellow and green meaning its fully charged correct . This took me about 3 hours not 24

Lithium doesn’t like hot or cold, so how does this hold up sitting in car, in extreme temps?

I live in central kentucky where we get all kinds of weather.. 100 degrees down -10 most every year. Mine has performed in all kinds of weather. Just last week i used it to start a friend’s car. It had been in the floor of my pickup for 6 months. Turned over a big lexus engine with little effort.

Do the clamps have to be removed quickly like with other chargers? To keep from frying the electronics?

This is not a charger, it is a jump starter, and you do not need to hurry to remove the clamps on any jump starter.

Can this trickle charge a car battery?

It’s a booster pack only not a trickle charger

Why does one say boost and the other one says genius…on the gb40..and why are the claps difernent on tje two..

They are both the same gb40 product. The older model with the word ‘genius’ has larger clamps.

Can i leave the cigarette lighter charger plugged in to keep the unit charged?

Apologies for the delay in response! As long as you’re using a usb-powered port rated at 2.1 amps or less to charge your gb40.

Do you have a repair facility? Mine will not hold a charge. If so, where do i send it?

I think i already answered one of your questions on this topic. You are asking this question in amazons customer question and answer area for the jumper. I doubt that anyone from the noco warranty dept has time to check here for notes like yours. You need to look noco up on the net and contact them directly. Its not all the difficult to do a google search. It wouldn’t take any longer to do than what you’ve already done here in this customer question area on amazon.

How long does it take to charge battery? Recharge unit? How long does charge last?

It will hold 75% of each charge for a year or longer. The time it takes to charge depends on the current being used to charge it. At the max it can accept of 2.1a it charges fully in about 3 hours.

It clearly says in the manual “the gb40 is not suitable for any other type of battery other than a 12 volt lead acid battery”?

The gb40 is suitable for use with lead-acid battery types, which includes wet-cell, gel-cell, agm, agm+, maintenance free, and efb batteries.

How long will it keep a charge? I am gone for 3-5 weeks at a time for work. (4.0l jeep wrangler)

It will hold 75% of its charge for a year or longer. We recommend topping it off once every six months to make sure it stays fully charged but 3-5 weeks should not be a problem at all

The gb40 instructions say it should not be stored in an area 80 degrees or higher. My car & garage get higher than 80 – what happens then ?

The gb40 should never be stored in temperatures hotter than 80c/176f, and the recommended storage temperature range is -20c/-4f to 50c/122f. Storing the boost outside of this range can cause damage to multiple crucial components of the jump starter. If the location you are storing your gb40 in may reach temperatures outside of this, then we would recommend storing the boost in another location.

Can the noco genius boost plus gb40 be used as a battery tender?

Hello pgzone,
the gb40 is a jump starter and should be used when your vehicle requires a jump. If you are looking to maintain your battery, the gb40 should not be used for this purpose.

Simple question: (i’m a woman) how many apps for 4 cylinder honda accord?

The question should be how many amps? Not ‘apps’. The typical battery rating for a honda four cylinder is probably less than 700 ‘cold cranking amps’ (cca). The cca represents the maximum output current in amperes a 12v battery will produce while cranking the cold engine. Actually it is the car’s starter motor that draws, (uses) the current produced by the battery. The noco cb40 is purported to produce 1000 amperes for a limited time frame when attempting to ‘jump start’ a vehicle. This 1000 ampere level is more than adequate to ‘jump start’ a four cylinder honda engine.

How it charge it? Have a charger? Works with 220v?

Yes it work with 220v if you use a 220v rated usb charger meeting the usb amperage as provided by the manufacturer. I do have a charger that will work at 110v and 220v i purchased in germany with all the necessary wall plug adapters, the germany schuk plugs, english plugs, as well as us/canada two or three hole plugs. Personally think the associated high cost is related to all of the included adapters.

Noco boost- jumps your vehicle faster than you can dial a tow truck!

Years ago, a co worker nearly lost her eyesight, when the battery she was jumping exploded- spraying battery acid in her face. I have had a fear of that happening to me, when the cables spark- as a result, i have to get someone to jump it for me, or call a tow truck.
When i used the noco40 to jump my dead battery, there were no sparks when i attached the cables- i was able to jump start it right away, without anyone helping me… And i arrived on time for my drs appointment!
When i called my car ins co about getting a jump start a few months ago, the man sent to help me used a noco boost- he said it would start the battery right away, and it did. I bought one, and it paid for itself the first time i used it! Missing a drs appointment when i’m sick, and having to reschedule means i can’t get the help i need… Putting me at risk of getting worse. But being out in the summer heat while running a fever & dealing with a dead battery- that can be dangerous. A fever can go much higher, resulting in heat exhaustion or even heat stroke…
Having a way to start a dead battery by myself, that sets my mind at ease! There are other bonuses as well:
~i can easily help a neighbor right away, if they run into problems. ~hurricanes are a way of life where i live… I can use the noco to keep my phone charged, even if we don’t have power for several days, or even a week (i have a
solar charger that can charge the noco during the day).

Saved my friend 3 times first week i had it!

I had just bought three on these on amazon prime day, one for each of our vehicles. We went camping with some friends and i kinda bragged about it to the husband. He i haven’t ever needed anything like that. He just always keeps a good battery on his truck. Later that day, he got in his heavy duty dodge pickup truck and the battery wouldn’t turn over the engine. My husband asked me to bring them my starter which i did. It started that huge truck right up instantly! Both men were very impressed! It was used 3-4 more times that weekend while we were there. I just let him
keep it in his truck until he was able to buy a new battery. Our friends said they were going to order one too. (ironic timing, i know!)

my husband had been skeptical because he has a huge jump pack in his truck but this compact one worked just as well!

I had doubts…

The battery for my wife’s 2016 x3 sdrive2.8i is completely dead (nothing electrical turns on) so i decided to get this product to jumpstart the battery so i can take the car to a shop. I got it the next day, but i had doubts that it will work given the battery pack is half the size of my laptop’s power pack. It took 4 hours to charge from 50% to 100%. I followed the instructions on how to hook it up to the battery… Waited a minute since the car’s electrical came to life…the dashboard giving me a bunch of errors and warnings…functions that rely on a good battery…i gave it a shot. The engine fired up normally—doubts erased. The battery pack is rated for 20 starts on a single charge, but i thought it drained it since the battery was completely dead—it still has , or close to, 100% since the green led on it is still lit. This is so worth it.

I'm amazed

I saw someone start a car with one of these a while back so i purchased one. I’m amazed at how well it works.. First my wife’s 2019 honda crv wouldn’t start, so i hooked this up not really optimistic that it would work. But her car started as if from a brand new battery. Then my son was having what he considered to be an electrical issue with his honda civic. There were all sorts of electrical warnings when he tried to start the car. He was about to have it towed to the honda dealer. I took this over and his car started instantly. (side note: my other son had an issue with his 2019 honda battery as well. Don’t get me wrong, i love my hondas, but their batteries absolutely suck. My 2017 silverado has never had an issue with its original battery)

Great little lifesaver! Simple to use!

This unit is a real lifesaver. I was stuck at my office with a dead battery on my truck and nobody had jumper cables. 1 guy had one of these. We clipped it on and it fired the chevy 350 over immediately. I bought 2 of them that weekend and gave one to my wife. It saved her that very next week when the battery died on her suv. She was extremely happy with it. I keep mine in my computer bag that goes with me in my cars or motorcycle. I even used it to jump start my riding lawn mower.
My only complaint is the holder to put the clamps on gets lost easily. Mine is in the depths of my truck now. Be good if it was part of the battery pack or attached somehow. It’s no big deal. The bag that it comes with keeps things togeather.
I love this unit!

Just buy it!

Super easy to use. Purchased it a while back to be safe when we were traveling out of state. Single mom with two kids. One day we are in the opposite side of town at 9:30 coming home from a b-day party- truck is dead. I opened it up and the flash light had been on from the last time i took it out to show someone. It still had battery to jump the truck. That is the only issue. The power button doesn’t need much to turn it on. But still, dumby proof because it got us home lol. I charged it and put it back in my trunk. It has done well over the summer heat in my truck and you only check in it every couple months and charge it at 6 months if needed. Youtube videos on how to use it charge it -yes it is easy but when you get nervous sometimes having that youtube video helps. Get it for emergencies, for your young drivers, for road trips. Worth it.

Dead battery & dead alternator – started and ran car.

Wife’s car had bad alternator, battery died and car stopped blocking traffic. Used regular jumper cables from my car, car started but died again as soon as jumper disconnected (bad alternator). Bought this specifically to have a small device that could jump start the car and power it for a short time, long enough to drive car off road to safe stopping location. Tested this by disconnecting alternator and battery. Jump started car using gb40, and drove it for several minutes (just to test). Disconnected gb40 and car died (alternator disconnected). This proves that the unit will both jump start the car and power it long enough to drive to a safe location (and probably for some length of time, tens of minutes, longer – but did not test that).

I must add to my review that i asked noco specifically about doing this with the gb40 and their reply was ‘manual override is not designed to power devices or act as a battery replacement and doing so could damage the device.’ so while demonstrating it is capable of powering the vehicle as i noted above, do so at your own risk. It does what i specifically bought it for, so i’m satisfied.

Three jumps in three hours

I bought this starter box two years ago after having my battery die with my suv (v6 lincoln) while it was in the garage (facing in). Had not needed to use it until last week when i was headed to a funeral service and tried to start the suv. Was able to start the car in the garage, but figured i would not be able to start car at funeral home. Plugged the box into the usb in the car and headed to funeral (20 minute drive). 60ish minutes later, went to car and ‘click click click’ used the starter box to start car and went to lunch with the family; plugged the box back into usb on the way to lunch (15 minute drive). After lunch, i had appointment at dealership (scheduled for routine maintenance before battery issue). Did not even try to start car, just hooked up starter box and fired the car up. Three jump starts between 10:15am and 12:30pm.

Ps – did not even get dirty while using the product. Wore my dress clothes the whole time. Buying one of these for my wife and two children!

It got the job done!

At first i was getting frustrated, because i clamped the battery terminals, turned the device on, waited 30 seconds and nothing happened for the first 3 attempts at jump starting a completey dead battery on my 98 camry that’s been sitting for weeks. I then watched a youtube video that said to press the ‘override’ button (which is a red exclamation mark on the front of the device) if the device is not detecting the battery. So i did and wallah! It started up that old car with no effort. So i highly recommend this product for that reason. The only cretique i have is that the ‘on’ button is right on the front of the device. They should’ve added a cover over the button so that you won’t accidentally turn it on and drain the battery. It won’t be able to jump start your car if it’s dead it’s self.. Also it should’ve came with a case instead of little bag. If i’m paying $100 this is what i’m expecting. They didn’t even include an adapter to charge it now that i’m thinking about it.. Oh well. It did what it promised.

Charging cord stinks

So i had an incident traveling where my battery died and i needed one of these, so i bought it. I have a noco trickle charger that has worked great for me in the past, but this is nice to have on hand for a quick save. Can’t say that i’ve used it yet “in the field”, so i can’t comment on that. But i like the design and with the case i bought it’s really convenient.

Can’t give 5 stars though because the charging cable it came with didn’t work! I plugged it in, tried it with different power sources like a usb to wall cube, the car charger attachment, and my computer usb connection and it wouldn’t show it was charging. I grabbed another micro usb that i had lying around the house and it immediately started charging and finished within a few hours. So it appears all is well now, but the cord they sent me is crap. I didn’t bother to reach out to them over the cord since i had another one. But it was disappointing to get this and not have everything included working fresh out of the box. I hope the battery itself holds up for me for a long while! We will see though!

It works great though some minor design flaws

This is a great jump starter box. Has lots of power and easy to use.

Now the design flaws. The buttons are too easily pressed. The power button doesn’t seem to be a big deal but twice now the light has been turned on and i didn’t know it because it was in it’s pouch and had drained the battery twice both times i went to use it and couldn’t.

The second one i bought was on a prime day and the cases were on sale so purchased two of those to keep it and the buttons safe from being pressed.

The light works great but i gave it two stars because of the button.

The need to put some raised plastic around them or make them sunken or even require a long press to turn it on. I’m guessing it was bumped on something when i put it in the car which turned the light on.

Just be careful when putting it in the car or where ever you store it and check it regularly to make sure it has a good charge.

Only 4 stars on safety because of the buttons.

Very convenient and portable but…

I bought this for a car i had that i couldn’t move to a place where i could jump it using another car. At this point the battery had been dead for probably two weeks. The noco did not start it. My mechanic brought over his much larger portable charger and got it working. But i turned the car off because i was going to go get gas before going to get a new battery. The car would not start again, so this time i tried the noco again and it did work. So the point is it can jump a car battery depending on how weak the battery is. If it has not been started in a week or more this probably won’t work. Less than a week; it probably will. Can also charge your phones. Good to have charged before a storm.

Great for those just in case moments

My car battery lasted 6 years with no problem until it didn’t all of sudden last week. The person who helped jump my car had one of these, so i bought it. However, i bought a new car battery, but this is nice to have for those just-in-case situations or to help others in need. I hope i never have to use and if i do, i pray it doesn’t let me down though these exceptional reviews should prove it should. I did note that the light wasn’t as bright as i expected. I know the technology around flashlights is vastly improved these days.

Charged up and ready to go!

Product is charged and ready to go.
I’d been following jump start devices for a while.
My intention was for emergency jump starting vehicles…
The reduced size and capability these type products is amazing to me!
The added benefit of remote phone and computer charging is great… Camping etc.
The light is bright and useful.
I’m reasonably confident the product will function as advertised, based on increased battery technology, cordless tools i use and positive reviews, and look forward to more safely jump starting vehicles without using my regular cables.
Not that it happens very often but i’ve always carried jumper cables in my car which have come in very handy for myself and other motorists…
I’ll probably order the hard case for it rather than the bag it comes with.
Good night & good luck

Connection is persnickety but otherwise easy to use

Happy enough that i decided to keep it but wish it didn’t take half an hour (not exaggerating) to get the clamps placed just right so that the jump starter recognized that it was connected to a battery and therefore usable. But once that magical connection occurs, it works great. The battery of my jeep (2018 wrangler jk) was so dead that even once started and driving i was still having electrical issues but the jumper started it with the first crank. My decision to keep the jump starter was largely due to the fact that it does have an indicator light to let you know when the proper placement of the clamps has been achieved.

I’m not sure how this thing works so well but you can pretty much put it only totally dead battery in about 30 seconds my truck will crank. But if you use jumper cables you have to wait about 10 minutes so this thing is pretty awesome and it fits in my glove box.

This box got juice!

This thing was an emergency purchase as i was facing a workweek and a car that refused to start. Asking for jumps is doable, but i’m way too stressy to want to do that every single time i wanted to drive somewhere.

This little pack jumped me in the morning to get to work, jumped me after work to go to an o’reilly’s (where i learned that my 10 year old battery was the issue), jumped me out of their parking lot to the advanced auto parts down the street, and jumped me on my way back home.

That’s 4 whole jumps with minimal fussing (i got way more practice hooking it than i would have liked), and the battery pack still read 3/4 charge.

Set up is easy, charge it, plug in the jumper cables, attach it to your car battery (mine is positive terminal first, but i make no claims that yours is the same), push the power button on the pack, and start your car. Worked with no issues all 4 times.

Can charge phones/other devices, and comes with a passable flashlight built in as well, which is neat multipurposing, but not something you’d buy this for imo.

Complaints would be that the clamps are a little stiff to start, or maybe i just have weak hands.

Super useful stuff, and it’s something i’d recommend to anyone that gets stressed out by asking strangers for jumps.
