NOCO Boost X GBX155 4250A 12V UltraSafe Portable Lithium Jump Starter, Car Battery Booster Pack, USB-C Powerbank Charger, and Jumper Cables for up to 10.0-Liter Gas and 8.0-Liter Diesel Engines

Works great, I use it daily in Tow industry, on a single charge it jumps about 10 cars, depends on the battery and a drainage of course, works for electric also as a temporary battery just to move the car off of the street to the curb when the vehicle stoped at the middle of the street due to a low or dead battery, jumps 6mont none operated vehicle with using override future, diesel trucks no problem, gets fully charged on a vehicle cigarette lighter about 4-5 hours

I love this product ! JUST MONEY SAVER. When I park my 2015 Freightliner Cascadia semi truck in yard for several days, its batteries are usually drained. So, it used to cost me between 50-150 bucks for jump start ( depends on person helping to jump start ). Then I found this product and bough. It has been saving me hundreds of dollars. With full of charge , it jump starts dead semi batteries 4-5 times. When you charge it at home , it might take 8-12 hours for full charge. Also you can charge your with it.

This particular model sits on the threshold of commercial and home use. If you are only jumping the occasional four or six-cylinder passenger vehicle, it is probably excessive for your needs. If you have a need to potentially jump multiple vehicles in a day or vehicles with larger engines, or a combination therof, the GBX155 will suit you well. Also, it is easily stored in the optional storage case, which I recommend, and is both smaller and lighter than other competitors with similar capabilities.Will start anything from a medium-duty truck and below with little to no issue in sub-zero conditions. It just might need a top off charge right after if you are jumping something more demanding, such as a mid-size to larger diesel engine or large gas engine in colder weather, which isn't difficult and can be done via USB-C fast charge in your vehicle between calls with the appropriate charger.I use this model for roadside assistance duty and it has no problem keeping up with jumping battery after battery in below freezing conditions so long as you monitor the battery level after each use and top off accordingly (much below a green charge level in colder weather and it will start to struggle with bigger engines if the battery is completely dead).Pro Tip: do not leave this, or any other NOCO chargers in your vehicle during extreme (hot or cold) temperatures. If they are too hot or cold, they will not provide power to your vehicle battery.

This product looks and feels it’s made To be really tough. I had a smaller version of this for years but now I’m dealing with transporting cars in the snow which are completely dead at times. Will update in a few months about the performance of this particular unit.I am a little disappointed with one key factor as advance as this looks I was very surprised not to have a C port to C port charger. This unit was way too expensive not to have that included with the product. Also the two A USB out ports are only 2.1A. That is nuts, as advanced this unit is Those A ports should be higher amps in the year 2024.My $50 portable phone charger has higher amp in its A USB out port.Do!!! not invest GB-X series of Nico products.This is hands-down, an inferior line of products Compare to GB models. I am a true believer in Nico products. I had GB 40 for 4 1/2 years and GB 50 for about six years.My GB 50. So considering that, I decided to go a step up and invest a serious amount of money and get GBX 155, Big mistake on my part like big mistake. my GB 50 had more backbone than this GBX 155. For Contrast I jumpstarted two dead batteries Off Jeep patriots, a dead battery of a F150, And a dead battery of a Chevy Malibu. And this jump box was dead, Down to its last bar. Compare to the GB 50 I was able to jumpstart almost 9 cars before it died out. I will be sending this back through warranty. Hopefully they find that there’s something wrong with this and fix it but if they tell me nothings wrong with it, they can keep it.Pls !!!!! Don’t buy noco GBX models. Not a good productI still recommend Nico GB models. They are way better.

I am extremely impressed with the NOCO Boost X GBX155 Jump Starter! It’s compact yet powerful, and it started my car with ease even after the battery was completely dead. The safety features give me peace of mind, and the design is durable but still portable enough to keep in my trunk. Definitely a must-have for anyone looking to avoid being stranded with a dead battery!

works great i've had to use it 2x times since i got it and both truck fired right up
