NOCO Boost X GBX45 1250A 12V UltraSafe Portable Lithium Car Jump Starter, Heavy-Duty Battery Booster Power Pack, Powerbank Charger, and Jump Leads for up to 6.5 L Petrol and 4.0 L Diesel Engines

It works, buy it !!! This is an excellent bit of kit, it will start your car up with a completely flat battery with no effort whatsoever. It’s very small and packs in your glove box if you so wish. It’s so easy to use and changes up from a USB point so you can charge it while you’re driving. Don’t be fooled by its size. Would definitely recommend.

This NOCO Boost X GBX45 is a top-quality jump starter that feels well-built and reliable. It’s powerful enough to jump-start petrol and diesel engines with ease, making it a great emergency backup to keep in the car.I also purchased the carry case, which makes it much easier to store neatly in the boot without worrying about damage.One of the standout features is the built-in LED light, which is extremely useful for nighttime breakdowns or when you need extra visibility.If you need a compact, high-performance jump starter that’s easy to store and ready when you need it, this is a great choice.

Bought to overcome battery issues on my Peugeot Boxer Motorhome, arrived partially charged but charged anyway for peace of mind, uses USB charger, seems to charge fairly quickly, under 30 minutes, Have had to use once already on the van, easy to use, wires long enough and van started immediately, impressed, LEDs on unit went from green to amber so don’t know how many ‘jumps’ it may have, have recharged again just in case. The unit is quite compact and has a cloth bag, other accessories are available. Went for the slightly bigger unit as other reviews suggest to. Used on Peugeot Boxer 2.2 Motorhome.

Surprisingly compact considering the power it delivers. I bought it after a flat battery, and the breakdown guy used one. I opted for the GBX45 rather than the GBX40 for that extra bit of oomph and flexibility at a little extra cost. Petrol engines up to 6L and diesels up to 4L. Excellent bit of kit. Started my motorhome in an instant. Definitely recommended.

I originally bought this as an emergency boost for my Land Rover defender which is nearly 30 years old. However I’ve only used it on my 2012 Audi 2.0 tdi technik. On a full charge it will only start the Audi once when the battery is reading 12.3 volts. A modern Audi will not even activate the starter if there isn’t enough charge in the battery to turn the engine over and successfully start. That’s a minimum of 12.5 volts on my ‘12 plate. It does work but you’ll only get one go at starting the car on a charge. Recharge takes about 7-8 hours after one attempt. In conclusion this product works in a emergency but will only work once on a 2.0 tdi Audi. Generally Diesel engines need more current to start than petrol so that might improve things a little. That said, it’s good to have in the car in case you accidentally flatten the battery beyond starting voltage but not completely discharged.

Bought this to start my van (Peugeot boxer 2.2 diesel) charge it fully for a few hours, connected it to my van and using the override button, it started my very dead battery. From using it a few times, I would say you'll only jump start two to three vehicles before needing to change it which takes four to five hours.The GBX45 is well made with good strong crocodile clamps, the leads are good but could be a little longer.It's easy to use, not to expensive just a shame it doesn't come with a hard case.

This item is not what you expect. I bought it as a Booster for my classic car but thought I would opt for the Noco GBX45 as it was advertised to also be great at charging other devices such as iPhones. However in reality it won’t charge much at all 1 iPhone charge and it’s flat. Contacted Noco and they said that’s correct it is designed that way. I will return and buy a cheaper alternative which actually does what it is advertised to do. In my opinion this is not worth the money.

Bought this as my 2015 diesel astra had stood for 3 months through winter after having foot surgery.I was a bit skeptical at first, however endless good reviews gave me confidence to buyThe booster arrives approximately half charged, so charged it fully using my phone charger before use. Charging input is USB C. The booster comes with a usb to usb C lead, so will charge from any usb socket.The battery on my mk6 diesel astra was completely flat, not enough to work the central locking. My car was parked 200 yards away, so didn't fancy lugging such a heavy battery home to charge it.Connected the unit, had to use the manual over ride as the car battery was so flat.Left it about 30 seconds before attempting to start, I was expecting it to just about turn over, however it started instantly, and as it would normally.Bearing in mind that the standard battery is quite large, and 80Ah capacity, it's astonishing that it started the car so easily.Very well designed and pretty much idiot proof, and solidly built. There are cheaper alternatives, however I'd rather buy something decent, if a cheaper item doesn't do the job when in an emergency situation then it's money wasted.Chances are that I might not need it again, however keeping it in my car, I'm sure it will help someone else, or myself in the future.Very highly recommended indeed.
