NOCOBattery Accessories Gb150 Boost Pro 4000a Jump Starter

First off, this product arrived on time and undamaged.Initial Thoughts:This product was packaged very well and it seems quick sturdy and well made. It arrived with a minor charge and took 3 “full” days to fully charge it to 100% while utilizing the included USB power cable in a North American Wall Outlet with USB adapter.Why We Bought It:My wife and I own a H1 6.5L diesel dual turbo (two 12V batteries system) and we live in a region where the days typically stay below freezing and even in the negatives for weeks on end. This longevity of cold weather frequently results in damaged and drained vehicle batteries in our area. In the past, we wasted a lot of money on new batteries until we bought the NOCO Genius G4 Charger. Unfortunately, we cannot utilize it as a trickle charger due to the distance the vehicle has to set away from a power outlet, but we can easily remove the batteries to repair or “boost” them when needed. To date, we have been able to revive many (6 batteries), but not all, damaged and/or drained batteries. The G4 Charger is a hit and miss with us honestly (as our review on that product states); but overall, when it works, it saves us a lot of money instead of frequently purchasing new batteries. Due to our understanding of that product's built quality, we felt purchasing the NOCO Genius Boost Pro GB150 would be a safe bet. We also felt that as long as we can start a vehicle with the GB150, we can at least get it to where we need it and then us the G4 to fully charge it and/or repair it at a later time. In short, the GB150 does seem very well made and sturdy.Before I progress, it is also important to mention that prior to taking the leap in purchasing this product, we even attempted to keep our H1 attached to 4 interconnect 9W NOCO Solar Panels (trickle charging system), but we quickly discovered they are useless for a 2 battery system (even in the summer months). That being stated, the panels are good for charging cell phones and other electronic devices over a "long'" period of time in “direct” sunlight. Since our prior attempts with 4 NOCO solar panels didn't help us maintain a continuous charge and since other battery jumper devices never had enough amps to jump our 2 battery vehicle, we bought this NOCO Genius Boost Pro GB150, charged it upon receiving it, and have waited for a good day to test it.Initial Conditions Tested In and the Results:We have not driven our H1 in 3 freezing weeks (via being out of town) and today we awoke to 7 inches of snow and -5 degrees F. After attempting to start the H1, there was not enough power to crank it over prior to using the GB150. However, once we attached the GB150, it only took 2 cranking attempts and the H1 was purring with no issues. As such, this product works!However, we did experience one flaw. Supposedly, this system is supposed to prevent sparking unless you override the system and turn off its safety features on a fully drained battery (below 2V); however, on the first crank it sparked significantly and suddenly. Since the H1 is so wide and since the view was restrictive by the engine when we cranked it, we were unable to see what initiated the spark. On the second attempt, we checked the connections (which seemed fine) and attempted to crank it again without touching any clamps between the battery terminals and the GB150. This time there were no sparks and it started right up.So you may ask, why did it spark the first time and not the second when no cables were touched? We have no idea. Perhaps we missed something the first time, but we wanted to warn everyone that there “is” a potential for sparking so please be careful. Perhaps there was some corrosion on the terminal or perhaps some snow (since it was snowing and we did this outside) created a short or some sort. In either case, this product “did work” which makes it a good investment for us. We hope it lasts and gives us years of problem-free results.How Long To Recharge After Use?It took approximately 5.5 hours to recharge the GB150 back to 100% after utilizing it this morning. Again, this is utilizing a wall adapter and “not” a computer or cigarette lighter adapter as it states it is capable of doing.Conclusion:With everything considered. This product is well made, sturdy, and does what it’s advertised to do. However, since the first cranking attempt resulted in unknown sparking, it is important to remember you are working with electricity and you should always utilized the proper safety protection (goggles, gloves, etc) when operating this booster. That being stated, in utilizing this product with the NOCO Genius G4 Charger, we finally have a winning system that is saving us money. We hope this review helps.

This device is insane .I have been using standard 50 pound jump starters for years and they usually , but not always , performed sufficiently , and not always reliably . Lately , for the last 2 years , I have been dealing with a failing " battery saver module " in my 2007 Ford F350 CrewCab 4x4 6.0 diesel pickup . The short explanation is that when the outside temps drop below 60 to 50 degrees , the battery saver module kicks in . Once the days get cooler and the BSM activates it completely drains both batteries in my truck in about 2 days while my truck sits unoperated . My standard jump box just wasn't charging sufficiently anymore to jump my truck from a dead start , and about 2 weeks ago it completely failed even though it was as charged as it was going to get . After reading up on these type of jump starters and reading tons of reviews for different brands and sizes of these jump boxes , I wasn't completely confident that these things can or would actually operate as the manufacturers claim . I decided to purchase the NOCO GB150 mostly because ;1. They are an American manufacturer and ...2. because they have been manufacturing vehicle assistive devices for many years and have an established reputation and ...3. because their machines aren't built around add on cheap , junky , gimmicky crap like tire inflators , laser lights , compasses , radios , mini winches , etc....its just a solid jump box built into a strong , high quality housing with a useful , quality LED headlight and a few plugs for USB and charger adapters , and..4. it seems to have better overall safety features than the other comparable brands , plus it is rated for much larger engines , and I did not find any other brand offering a machine rated for such large engines and..5. In comparing the NOCO GB150 and it's parts such as the cables and post clamps to other brand boxes , the NOCO quality seems to be solid , professional quality .After receiving the box and examining it , it is my opinion that this is a finely manufactured product , no cheap or flimsy parts at all .Charging it completely out of the box as advised in the user manual took about 12 hours . The following afternoon I went out to my truck to start it up . It was about 3pm and the afternoon temp was about 75 degrees , and the overnight temp got down to about 49 to 53 degrees . My truck had been parked for 12 days without being started , and the batteries were completely dead . I attached the post clamps , waited about 1 minute , and keyed the ignition switch. The engine kicked over vigorously , no lag , no hesitation . I went into town to do chores and run errands , making several stops throughout the afternoon . I jumped my truck 5 more times that afternoon . When I returned home , I checked the box and the charge indicator gauge showed the box STILL at 100% . I left the box on the passenger side of the floor for the next use . I went out 2 days later , jumped my truck that morning and 4 more times that day . Upon returning home I checked the box and the charge indicator gauge showed the charge at 75% ! Think about that ...I jumped my 6.0 diesel 11 times over a 4 day periodwithout recharging this box , and it only used approximately 1/4 of the contained charge ..that is unreal .After reading the reviews , the only concern I had --apart from this box actually performing as the manufactures claimed it would -- was the complaints from a few customers that the power component ( battery pack ) failed rather early ...there were only like 3 or 4 reviews with this complaint ...in contrast there were hundreds of 4 and 5 star reviews for this box , none of which mentioned the box having a short lifespan or otherwise failing . Also , there were a few follow up reviews from guys who had purchased the box more than a year or more prior and talked about how the box was still functioning dependably as it was designed to do .One other thing to keep in mind is that should the battery pack fail , NOCO states in its user manual that it does rebuild the box should the owner send it in for such service .In conclusion I absolutely recommend this box or its smaller versions . In my opinion , NOCO builds the best quality box , and judging from other reviews , also maintains a responsive Customer Assistance department which is important as these jump boxes are not a throwaway item . Buy this jump box . 5 STARS !

This things works awesome I have yet to find a vehicle it won't start. Even if the vehicles battery is completely dead this unit fires it right up. Charges up fast and will start many vehicles before requiring a recharge. I originally purchased a cheaper model but it just didn't have enough power so I purchased this one instead and it does exactly what I need. Highly recommend.

This thing works great. Takes a long time to charge it up but once you do it lasts a good while. It’s never let me down.

Best Product✅Powerful✅1 full charge was enough for 8-10 times, and it took only 25% of Battery life.I have shop ill do Super Duty Ford 6.7 diesel, it works with no issue. Even if battery dead, it can boost your dead battery easily.✅Just put on charge again, ill do Roadside assistance, will try on Semi-Trucks soon and update my review, that what is the highest engine capacity for cranking, cause it says it can crank 7L diesel engine only, but I don’t think it’s max of its power.
