NOCOBoost X GBX55: 1750A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 7.5L Gas and 5.0L Diesel Engines

1. Functionality: Works very well for my use. So far, I've used it twice on my 2012 Honda Civic when the temp was -10F and my car wouldn't start. Plug it in, light was chasing, started the engine, boom, works like a charm.2. Jump Capability: Since I've only used it twice, and on my 2012 Civic, small car, I don't really know how well it works with SUVs & Trucks, but I would hope it work. Will update later if I use it to help out friend's cars.3. Battery Life: Fully charged, used it twice within two months, drained the battery to half or so, if I remembered correctly. So, I would say you could use it to jump start about 4-5 small cars. Not sure about bigger cars.4. Ease of use: VERY VERY easy to use. Self-explanatory. Make sure you read up on it or watch video on YouTube on how it work, especially if the battery is completely dead and the light is not chasing and you have to use the "Override" mode.5. Compactness: VERY VERY compact. I put in my work backpack and bring it with my to work every day in case my car or a friend/coworker's car broke down due to battery drain or something. Or in the sever cold weather of -10F or below and car doesn't start.Overall, I would say it's very useful. Choose your own model and go down if you have to to save money. I bought theNOCO Boost X GBX55 1750A 12V model because I want it to be at least strong enough for my Tundra.

Started my 2011 Ford F150 Lariat Super Crew v8 5.0 without issue.Battery was completely dead. I did not check voltage but no lights on entry and no power locks.Connected my fully charged Noco that has been in the vehicle for 2-3 months. Power on. Counted to 40. Truck started as if it was fully charged.-I have about (12) Noco products. None of them have cause me issue or hesitation.The Noco GB40 took some extra work to start the truck in the past. It works well on my V8 4.6, my v6 3.5 and my v6 3.0. The 5.0 is just a little larger and seemed to tax the GB40.First (2) of these specific units were bought from a refurbished. Both were dead on arrival.Bought a new unit. Brand new. No issues.

The NOCO Boost X GBX55 has officially earned a permanent spot in my car. I’ve used it multiple times already—from jump-starting a completely dead SUV battery to helping a friend with a diesel truck and it hasn’t failed once. The power this thing delivers is impressive for such a compact device.What really sets it apart is the ease of use and safety features. It’s nearly foolproof no sparks, no confusion, just connect and go. The USB-C fast charging is a game changer, and the built-in flashlight is surprisingly bright. It also doubles as a power bank, which is super handy when you're off the grid or during a power outage.If you drive anything especially in cold climates or long trips this is a smart investment. Peace of mind in your glove box!

I waited to review this until I had owned it for a while and had a chance to use it a few times.I have an older 8 cylinder car that I use infrequently that also has an electric issue. The battery drains if it sits. I purchased this charger to keep in that car just in case. When the battery drains, it goes DEAD. i have now used this to jump the big 8 cylinder several times, it works instantly. I can get 3-4 jumps out of a charge.I also take this out on my boat as backup and as a flashlight if needed.The usb-c charging is nice since that is what my phone now uses, so I have multiple charging options.Overall this was more expensive than the models I was looking at but I’m glad that spent the money. This is a great charger.

I purchased this product less than two years ago and only used it twice during that time, both without issues. However, yesterday, my car battery died after sitting idle for a few weeks over the holidays. When I attempted to use the jump starter, I noticed the battery was low, so I plugged it in to charge. After about 30 minutes, I checked on it, but all the lights were off. I unplugged the device to see if it had finished charging, but it wouldn’t power on at all.I reached out to the company for support, and they said it was broken, and since my unit was out of warranty, the best they could offer was a 35% discount on a new one. For such an expensive device, this resolution feels inadequate. It's disappointing that the company doesn’t stand behind its products longer. I won’t be purchasing from them again—back to reliable jumper cables for me.

Hell yes this is a great item!.. I have a smaller version that I carried around and forgot I had for a couple of years until my battery shot craps, I remembered it, pulled it out and hooked it up and started right away. After 2 years of just sitting in heat, cold, whatever. Highly recommend. ( I bought this one to go in our truck, I put the smaller one in our car.)

I bought this after having another brand that didn't work for my truck. Mr truck has a coil that has to heat up before you can start and this thwarts the previous chargers I have bought.I have an 18 y.o. 3L turbodiesel truck that has an electric leak so it constantly drains my battery.My truck wasn't started for a month and the battery was dead. There was nothing, no clicks, lights, no power locks. Noting.Clipped this on, pressed the boost and heard the alarm beep.I walked around and started the truck the first time. Nothing else to say but this is worth the money

Over all decent now that I know to use over ride button. I dont like the very short cables, should've been 2" longer each. I put on a totally dead car and would not do anything and I was just about ready to pack it up and buy a regular booster pack, but then saw the over ride button. After pressing and holding over ride button, worked good and started 2 dead cars but was quickly down to second red charge light.One thing that is really lacking is a high wattage usb charger to plug in to. This thing really takes a while to charge with a normal phone usb.
