    • Works as it should! I would buy it again.

Review Image by SB SB
I've used it to jump off my 12V diesel lawnmower, a couple diesel pickup trucks and just last week my Caterpillar Smooth drum roller went dead after sitting for weeks with the key on. It's a large cat engine around 6-7.0L. I realized it was 24V and looked at the NOCO 4250A I bought and realized it doesn't do 24V. I was disappointed, I thought it did. I stuck the jump box on it anyways to see if I could at least give it some power just to get systems powered up. Everything powered on so I let it sit 45-60 seconds and said hell let me just see what it does. Turned the key and whomp whomp whomp it fired off pretty nicely. I'm happy with it. Would 100% buy it again. ... show more

    • Jumping power
Size: 4250A
I've already jump started 1999 school bus and 5 other diesel trucks with ease. The weight isn't bad for what it can do. If you use there cable to charge the charging time is short. It's the easiest jump pack I've used.

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

    • DO NOT BUY! ... UPDATE: Customer Service did the right thing.
Size: 4250A
I bought the NOCO Boost X GBX155 4250A for the "what if" situation. I pulled it out yesterday to use it for the first time and it is dead, will not take a charge at all. I did a google search and come to find out this is a common issue with the GBX series. I'm assuming I let it sit in a box for too long and it lost all of it's charge? I'm not sure. I emailed NOCO support and will follow up with what they say. 10.15.23 - Following up. NOCO will not respond to me after I showed this was purchased in July 2022. This stayed in the box as a gift and the first time I try to use it it won't turn on and will not take a charge. I'm blown away you can pay over $350 for something and it never work once. DO NOT BUY! 12.1.2023 UPDATE: Customer Service sent me a new Jump Starter. It took some time but they did the right thing. I'm bumping to 4 stars because of that, but it's being noted that you need to check on the battery and never let it run all the way down. I wasn't looking forward to baby sitting TBH, but it is what it is. ... show more

    • Started my semi trucks
Size: 4250A
Started a completely dead semi (Kenworth T680), easily. This thing is brand new to me so later I recharged it. Now I think I probably didn't need to already. A few days later I started another T680 that was also completely dead. This time I didn't recharge it and about a week later it started a completely dead reefer unit. This one was so dead I had to use the override feature. Again, it started fairly easily but I immediately disconnected it and it died. Think I should have left it running for a few seconds more before disconnecting it. After that happened it caused a whole "thing" because it takes so long for the reefer to go through it's start up cycle and you just have 60 seconds to start to use the NOCO so this caused a few times where the NOCO was powered up but then wasn't able to be used and had to start the whole procedure over again. Once I got the timing down though, again, it started the reefer unit fairly easily, let it run for several seconds before disconnecting the NOCO....good to go. I love this little unit. It's a beast! Had another one that's SUPPOSED to start semi's with 6000 amps (small little unit)....total dud. ... show more
