I often leave our cars sitting for a while and have had to jump them.
This has helped when needed, although I now attach a small solar panel to keep them topped up.
When needed, this worked Great and helped provide the power i needed to jump start the car with hardly any effort at all…So Easy!
Only time i had an issue is when the battery was so depleted that the unit did not turn on as it did not detect voltage, but i was able to use another power source to “trick” it into turning on.
Ovewrall this is a Great investment so you dont have to reply on others to jump your car if needed.

It works until it doesn’t I’ve had it about 3.5 years used it twice went to make sure it was charged right before a road trip and it was dead and it wasn’t charging when plugged into a wall outlet. Other than that I would buy it again once I get the funds available to replace it.

Good product. I have an older Ford Econoline V8 Van from 1999. It’s not driven often event though the battery was replaced a couple of years ago. Went out to start it after about 2 months of non-use and the buzzer didn’t even sound when sticking the key into the ignition. I tried hooking up a trickle charger for a couple of hours and while that did provide some power, it wasn’t enough to turn the engine over. I ordered this, arrived same day, charged it up which took about 1.5 hours with a high-power Apple USBC charger. Placed on the dead battery, waited about 30 seconds and the van started right up. I noticed the charge on the battery of the charger reduced by about 50% so if you have a large engine or diesel, you may need the higher power unit. It met my needs, and I will carry it with me in the van. I wish the leads were a little longer, but they are long enough to reach the positive and negative terminals of the battery. I think it is reasonably priced if you have a regular 4,6,8cyl vehicle.

I’ve been having to jump start a car every few days because I need to move for street sweeping. It’s been going good and this unit started it every time without fail. Well, that was until today. The battery was totally dead. I connected this unit and saw that the lights were racing or moving, but when I turned the key, not thing happened. Even tried to jump start it from another vehicle. So I went back to my desk and started searching for something with more oomph. I started watching the video on the new product I was going to replace this one with because it has a feature called boost. Then I went and watch the video of the unit I had which is called GBX45 Boost X. It has a button on it called override. So I went out to the car hooked it up, pressed override for a few seconds and voila! The car started very easily. I turned off the unit and the car died, but that battery didn’t have enough time to charge, so I will hook up one of those trickle chargers tomorrow. Bottom line…. this is a great jump starter, once you read the instructions!

Der NOCO Boost X GBX45 ist ein absoluter Lebensretter. Mit 1250A Startstrom startet er mühelos meinen 6,5-L Benziner und sogar 4,0-L Dieselmotoren. Die UltraSafe Technologie schützt vor Funken, Verpolung und Überladung, was mir ein hohes Maß an Sicherheit gibt.
Die Vielseitigkeit als Starthilfe und Powerbank ist beeindruckend. Ich kann damit nicht nur mein Auto starten, sondern auch Smartphones und Tablets unterwegs aufladen. Das kompakte, robuste Design passt perfekt in mein Auto und ist wetterfest, ideal für den Außeneinsatz.
Die Bedienung ist kinderleicht und die zusätzlichen Funktionen wie die LED-Anzeige und Taschenlampe sind sehr nützlich. Der NOCO Boost X ist ein Muss für jeden Fahrzeugbesitzer. Fünf Sterne!

Excellent product, very versatile and easy to use. With a full charge I have been able to start my car several times and the charge has a great performance, I recommend it 100%

The NOCO brand seemed to come up in a lot of my searches on various car forums as being a popular choice and for good reason. The build quality is solid, it includes thoughtful features like a 3 mode LED light and in/out charging ports. It comes with charging cables and a storage bag. The device is easy to use and already came in handy on a dead car battery…hooked it up, turned it on, waited for the status lights to come on and an easy jumpstart. Very impressed.

PRO – Works great at jumping very low or even dead battery, as long as it’s not too far gone.
PRO – Compact and easy to use.
CON – Takes longer than 48 minutes to full charge on USB-C.
CON – Pressing “Override” button takes about 2/3 of the charge off the device.
This is an excellent portable jump starter that will get you back on your way. It’s easy to use and store.

My battery on my car was dead dead. Like, wouldn’t even lock with my key fob and none of my dash illuminated when I opened the door dead. I charged this up fully— took only an hour or so because it comes 75% charged— and looked up the instructions online. Between connection and starting the vehicle, perhaps 60 seconds had elapsed. My car is running, the engine turned right over like it was brand new: no clicking, no multiple attempts at jumping, no awkwardly maneuvering another car to get connected with traditional cables. Best part is, you can get multiple jumps per charge, as once I was done, all my lights were still showing fully charged. I will be recommending this to every person I know who doesn’t currently own one.
