    • Powerful, Reliable, and Compact – The Ultimate Jump Starter!
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! ... show more

    • Life saver for truckers
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. ... show more

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 product I still recommend Nico GB models. They are way better. ... show more

    • Does the job and does it well. Very well.
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. ... show more

    • Wow! This has some juice!
I bought this jumper because my Tahoe has a parasitic draw and I haven’t had a chance to take it in to get diagnosed. In the past two weeks, I have used it three times already. It charges by using an usb c. The charger came almost fully charged. Each time it jumps the Tahoe with no problem! Prior to this I have two other jumpers and they both struggle with starting a car with a drained battery. I love how solid this little jumper is. I carry it in my Tahoe as an emergency backup. And when I am riding my motorcycle to sturgis this August, this baby will be in my saddlebags! ... show more
