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.

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.

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.

We have an older hobby vehicle that tends to sit for long periods and need a jump. Even with a completely dead battery, this device started it right up no problem! You get multiple starts from one charge, too. Very easy to use and feels safe. I think everyone should have one of these in their vehicles, it's so much better than jumper cables for so many reasons! Easier, safer, and don't need another vehicle. Alternator goes out, you can still jump your way to a destination in many cases. Well worth the money and this is a reliable and user-friendly brand.

Product itself is nice and feels high quality. But after 2 months of having it and a singular use the device won't take charge anymore rendering it useless. In talks with noco warranty now...UPDATE: Had to pay shipping cost to warranty the item and after 3 weeks received a brand new one. Well GUESS WHAT!! The brand new one has the same exact issue out of the box. So now I'm out $150 for the item and an additional $30 for warranty. How is this company regarded as one of the best jump pack makers when they sell absolute trash like this?

This unit is amazing, very limited battery draw. Functions with no issues. Like the integrated light and usb port functions.

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!

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
