NOCOBoost X GBX55 1750A 12V UltraSafe Portable Lithium Jump Starter, Car Battery Booster Pack, USB-C Powerbank Charger, and Jumper Cables for up to 7.5-Liter Gas and 5.0-Liter 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.

Finally used mine for the first time I needed it. Was in a hurry and realized my new hardwired dashcam sucked all the life out of my battery. Remembered I bought this thing and went to the trunk to get it. Simply popped the hood and put the terminals onto the battery posts and went and it started the first try. No hesitation or slow starting. Fired right up. Unhooked it from the battery, put it on my charger in my garage and went for a drive. It took less than 5 minutes from start to finish to have my car running again. It was charged up by the time I got back home. Threw it back into it's bag and back into the trunk for the next time. It payed for itself today, great product!

The one of the best things I ever could have asked for that little is powerful it can jump start anything it’s a must have you can’t go wrong b leave me when I say get you one 👍🏽💯

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.

Currently I am having issues with my 2014 Dodge Challenger R/T HEMI not starting as it should. In January, I Purchased this as a stand-by to help me out until I could get to the shop. Unfortunately, I became ill and unable to do anything or go anywhere…ended up being in the hospital for a week….then needed time to recuperate…..it is now May and I can FINALLY be active! I have had to use this each time I tried to start my car as I was told to start it every now and then. Today was my first time getting to drive in months….had a doctors appointment. Had to rinse all the pollen, dirt etc etc off my car just to be able to see out the window….of course had to jump it. Then I recharged the jumper. 3 hours later I had to leave for my appointment only to find it wouldn’t start again. Thank god I had recharged the jumper because I had to use it to get to the appointment. Was there about an hour….only to leave and find out my car wouldn’t start AGAIN. This time it would not start until the 3rd try. Made it home and recharged the jumper and it was only on 1 red box. Each and every time I have jumped my car I have had to immediately recharge it or be in a pickle if I had to leave the house. What good is a jumper if you only get one jump before having to recharge it? I’m extremely disappointed I forked out over 200$ for this. A waste of money as I could have purchased a less expensive one that would have actually done the trick…but I went for the brand name instead…..my mistake! (My car had been worked on in November and had this issue ever since. But as stated, I was simply physically unable to return to the shop. Tomorrow I will be going there…finally). Regardless…this has proven, in my opinion, to be a waste of money and extremely frustrating.

A great addition to my toolbox. One of the additions that I always wanted to make. I have tried other jump starters from different retailers, and they fell far short of my expectations.

Overall amazing product but there is a pretty substantial design flaw. Pretty often I find myself turning off the led light because things got shuffled around causing the light to turn on accidentally. Today I went to use the jump pack because I had a dead battery and the pack was completely dead, I’m assuming because the light had gotten turned on and been running for who knows how long. They need to redesign it so the power button is more protected or honestly get rid of the light entirely.But the jump pack has been amazing other than that, keep it charged and in my car at all times, first time I have had to use it on my car. I use it on strangers cars mostly. But always starts right up
