I purchased a GB40 a couple years back for my son and daughter and a GB70 for my diesel. Recently I purchased another GB40 for another vehicle since I was sharing. I take the GB40 on the boat just in case. My tolling motor battery died while on the lake and i had about half a charge on the GB40 and thought I would see if it would work. I connected it to the trolling battery and was surprised that it worked well over an hour. It’s not designed for this but it worked in a pinch. You never know when you’ll have a dead battery and I’ve been stuck out before. Caught all mine on a special buy but if I was stuck out with a dead battery battery it would be worth full price.
I don’t use my car a ton as I am attending college, so over time the battery in my car runs low and I keep the NOCO jumper in my dorm so I can get my car going without having to ask a friend for a jump. The battery is more compact than a standard set of jumper cables so it can slip into a drawer or glove box and be there when you need it. So far I’ve only needed it once, but it fired up my 4 cylinder sedan without the battery charge status lights going down. Very pleased ?

I work 12 hour night shifts and got off work this morning a 6am. Upon arriving at my car, I discovered that my battery was dead. I popped the hood, pulled out my old jumper cables and waited for some else to come out to the parking lot. No one did, so I went back in and asked security if they could give me a jump. The officer came out carrying one of these NOCOs and said that he would rather use that than pull his truck around and use jumper cables. I was open to the idea but was extremely surprised at how quickly the connection was made and how quickly my car was up and running. Afterward, I asked the officer where he got the NOCO and how much they run. He told me that they are on Amazon for about $100. He said that he never leaves home without it as it can be used multiple times before it needs to be charged again and that when fully charged it can sit for up to a year without needing to be charged again. Before I pulled out of the parking lot, I got on my phone , went to Amazon and ordered one along with the wall charger and hard shell case. Surprisingly, Amazon had it all on my doorstep by 3pm this afternoon! I fully charged it (took about 3 or 4 hours plugged into a wall socket at work). If you decide to make this purchase, I would HIGHLY suggest that you get the wall charger accessory and use that rather than plug it into a USB port. It would have taken forever to get to a full charge that way.

This unit works GREAT.I can only assume that many of the negative reviews are from people who either didn’t read the instructions, don’t know what they’re doing, or possibly both.I had to jump a vehicle that had been sitting for months. Battery was stone cold dead. AutoZone jump box thing would only get a slight attempt to crank, then just clicking.Bought this unit, hooked it up….nothing. READ THE INSTRUCTIONS. if the battery is very dead, you have to turn on boost mode.Turned on boost, tried again. It cranked up better than a new 540cca battery, and fired up before it even finished the first turnover.Went to move the car, it stumbled and died. Hooked the Noco up again, once again started with a half a crank like it had a brand new battery.After I got the car moved, I plugged in the unit to let it recharge. It hadn’t even used enough power to need a charge. Just went straight to the slow green pulsing “maintenance” light.Again, read the instructions. Charge it completely before using it. Charge it after you use it. Check the charge every few months of non-use. Make sure you have a GOOD connection to the positive cable or jump point, and attach the ground clamp to the chassis/block/etc NOT the negative terminal. This gives the power a more direct path to the starter and fuel/ignition system.

When you unbox a product and the quality of the packaging, the multi box protection and the glossy printing on the box is as good as a new IPhone’s box, then you know the product has to be good. If they are willing to spend extra money on making sure the packaging and printing is of high quality I would trust them. In terms of the product itself, the battery on my 4Runner was dead and after hooking it up for 20 seconds it started immediately. I like the flashlight and the fact that you can charge your phone on it. In other words, its a good multi tool to keep in your car.
I have been keeping this in my car for about three years and absolutely love it. I charge it every three months to be sure it’s always ready when needed, but the battery only needs a little top off even after that long. I’ve used it to jump start both my own vehicle and to help out a stranger in the parking lot. It’s incredibly easy to use and works perfectly every time. I have a sense of safety and security knowing this is tucked under the car seat. I’ve also used it to charge my cell phone while camping and even the light has come in handy more than once. It has become the gift I send to nephews and nieces when they get a drivers license or go off to college. I highly recommend this product.

It was not fully charged when I got it (see first photo) but, plugged in immediately. Having electrical issues with my car and this saved the day. Worked first time. For me, didn’t have to wait 30 seconds but, think everyone is different. I previously bought another model that was similiar and had to return it because it did not work the first time around or held a charge but, after reading reviews from other diesel engine owners, went with this one and it has worked perfectly. One thing, would mention is if you use it, make sure to keep it fully charged where the cycling mulit-lights flash and is a solid green only light (like second photo). Great product and very happy buyer. Writing this review because after all the searching I did, wanted to help others out to save time.
If you were wondering.. Yes it can start 100% dead or no battery car jumps.I know it’s hard to find this specific information if you aren’t a mechanic etc. I bought another Jump starter I won’t name and the other one did not jump my dead battery. I was frustrated and pissed off that I spent $76 on the ineffective one.I bought it because the seller claimed that it can charge a completely dead battery when they answered someone’s question. I haven’t used the car in question for quite some time and the battery was drained completely.I had a Tacklife T8 and it worked on jumping 100% dead batteries but… It was stolen which is why I was looking for another one. Amazon does not sell the Tacklife anymore but Tacklife sells it on their website. I would rather buy from Amazon to be honest… Guarantees, refunds, customer service etc…But anyway, my refund for the previous jumper went through and will be credited within the week.Now, to the product… NOCO Boost Plus GB40… EXCELLENT. It jumped my 1.8 L sedan EASY. Easier than the Tacklife. Like there was no continuous cranking until start. It was just as if the battery is still good.And this is from 100% dead battery.Battery was dead as in when the key is turned, no sound whatsoever.The key to finding one that can cold crank a dead car is to look at the instruction manuals for it online. If it mentions a forced boost mode which both NOCO and Tacklife have and a warning about it… Then that jumper can start from dead/no battery.The warning is because the forced boost opens all circuits so if you have the clamps on the wrong connectors… The risk is sparking, fire, high heat etc. Is what I’ve heard/read. So, yea just color match and make sure the correct clamps are on the right connectors.

Good bye to jumper cables, or waiting in a scary place for a tow truck or other entity to come and give your car battery a jump.It arrived almost fully charged, and I topped it off before using it on a mid-sized car, and on a SUV.Why did I buy this?Well, after I waited four hours for AAA to give me a jump at 7 pm, and by 11 pm, no help arrived, so I told them, “Forget it, I’ll get a friend to give my car a jump in the morning.”I later learned that the car had a “phantom” or “parasitic” computer chip that drained the battery over a few days, much as if you left the lights on-the service dept. didn’t figure that out at first, hence the need for more than one jump over a couple weeks.While sometimes a drained battery may take a few jump attempts to give it a charge, and start it up, this device started up drained batteries immediately.It’s paid for itself easily, and I won’t leave town without it.
Noco’s GB40 provides up to a 1,000 amp boost (your vehicle’s electrical draw while starting determines how many amps will be needed) which is more than enough to start just about any car/truck/suv. In fact, a lot of car batteries don’t provide 1,000 amps.Physically, this unit weighs about 1lb, is easy to carry and could be stored in a glovebox or console.Safety features such as reverse polarity detection protect the user. There’s really no way someone can harm themselves or their car using this booster; everything is automatically analyzed by the GB40 before it will function.I own another GB40 and have jump started at least 12 people’s cars, 2 which wouldn’t start when they were already connected to jumper cables. I top off the charge about every 6 months – it usually recharges in 15-20 minutes using a 5V IPhone charge cube.Noco makes an optional case that I also recommend.
