    • Just Buy it, its completely worth it
Just go ahead and buy it, it’ll save you one day trust me. Let me tell a little true story basically I’m a bass head and I wanted a sub in my jeep so I took the kicker sub and amp I had in my truck and put it in my Cherokee unfortunately we did not reconnect the cable that travels from the alternator to the battery bus bar however the cable was on the post, the first sign of the problem occurred when the stop/start system was disabled shortly after driving away. I thought this was because the car detected the subwoofer was now drawing power so it disables the system so I ignored it. We did all this on Saturday evening and everything was going smooth, Until “Wednesday” came around. So I’m driving to work on the interstate in the first three warnings that came appeared were ABS, Stability Control, and my parking brake were all disabled. Forgot to mention my card did start mentioning something about a low power state but I didn’t know what that was about but now I know; Anyways I stop at a red light, and things start to get real problematic first my AC starts turning on and off and then my head unit blacked out. I put the card in park because I didn’t know what was going on. I opened the back of my jeep manually as the Rear powered door is also disabled. I glance over at my Subwoofer Amp (Kicker 800.1) and I see two lights on at the same time power and protect meaning the voltage in my car battery was below 10 1/2 V and I verified that with my multimeter as I work with AC units so I jumped my car battery off with a little bit of voltage from the pack and I was able to quickly get to work in the afternoon. It turns out I did not reattach the nut nuts for the battery lead meaning the car battery was never truly charging. If you’re thinking about buying a cheaper, one of these, you might want to stick with this brand as they are very reputable charge very quickly through USB-C power delivery, which is very handy. It is in my opinion the safest jump pack as you cannot short the output unless you override the pack, which I have done before sorry about that Noco, but I had to experiment. Sheep was work, but they’re usually made with cheaper batteries so they don’t hold a charge very well and they die pretty quickly so it might be only good for six or seven cranks. This jump pack also has many safety features and temperature protection. And it has a flashlight. I don’t know what else to say but I strongly recommend buying this jump pack. It’ll save you when you’re in a jam and it saved me from being stuck at a green light. ... show more

    • GBX45… Good to have and not need, than to need and not have.
Review Image by Chris Chris
Bought this in Nov. 2023, initially i didn’t use it but one cold morning in February my truck wouldn’t start, so i finally was able to use it and worked immediately. No having to get another car in position, no setting up jumper cables, none of that! i used it again in April (without recharging from the first time) to jump my sister’s car and again worked immediately. This thing is awesome. Ive used it other times to help coworkers, charge my phone or other devices while camping etc and thing lasts forever. I recharge it every few months or before i go on a long road trip. Just buy the thing, will make a good birthday/ father’s day gift to those who are into cars or other mechanics. ... show more

    • Works great, even when not fully charged!
I haven't used mine yet (got another as a gift, too), but got the same exact model a friend has. I was leaving work, and my truck battery decided to die that day. I went to turn my key, and only a "click", not even enough to turn the starter at all. I got my friend from inside work to come out and give me a jump start (I had cables with me). Instead, he pulls this out of his car and hooks it up to my battery. I ask him if I wait a minute before trying to start it, he told me to try right away. My truck started up right away! He then told me his starter wasn't even completely charged (he hadn't charged it for a little while). That was it, I was sold! Having cables is great if someone else is around, but what about when nobody is around? This thing covers that! Powerful, and has the other features listed. The only thing missing was a charger. It has the cable, but not the plug. So if you don't have one for this, get that too when you order this (C type charger). ... show more

    • Reliable and very easy to use.
Works great! 1st day I had it in my trunk, a little old lady at the store had a dead battery. Her car started right up on the first crank. Have used it for other people a couple times more since then. Everyone said "oh I've got to get one of those!" Very easy to attach. No sparking. Must remember to push the override button for jumping dead car batteries. I plan to use this during power outages to recharge phones instead of using the generator. It came with a thin fabric bag that I didn't like much. I would have preferred a case. So I just kept the cardboard box it came in and use that to store it. ... show more

    • Trusty AF
I successfully used this to start my car almost every day for roughly a month while I was having issues with my car battery. Just kept it on a 100w usb c car charger while driving so it would keep its charge. It's reliable and very quick and easy to use.

    • Packaging needs better info. and more attention to detail
I was happy to receive this unit which replaced a 'factory reconditioned' unit I bought from Amazon at a discount that didn't work at all. NOCO is a great brand and I expect this will work fine. However, I do have two comments: 1) lack of a manual. There is a thick "Safety and Warranty Information" booklet in about 80 languages which I assume is required by some national laws. But let's face it: working with a car battery can be dangerous. Instructions are important even if it adds to mfg. cost. I did find their well-written manual online and printed out the relevant pages (4 pp.). A final gripe: the bag for the charger needs a string tie that for sure keeps the charger inside the bag. There is a string but in order to make sure things stay put you have to tie the string yourself or add a bungee thingee, which I did. ... show more

This is my fourth Noco product. I believe they are top notch. Used to crank cars trucks lawn mowers and boats. Thus far never failed. Also have their battery maintainer. Something missing from this particular order. Contacted Noco and they replied within the hour with plans to remedy the situation. Great customer service. ... show more

    • Saved my butt twice
I have only used this thing twice in around two years, but both times it was ready and started my truck no problem. To me, that's worth every cent. Charges quickly and must be well built because it gets thrown around in the back of my truck and shows no signs of wear.
