It works! Not only that, but one year after it was charged...!
I used a Suaoki P4 before and was very disappointed that it never worked to successful jump start my (smaller) van. I now have a Transit Mk8 2018 2.0L & as a solo female who is building my van and plans to live in it soon, I wanted something reliable that could jump start me on the inevitable occasion that the battery got flattened (it always eventually does... no matter how careful you are for the most part) I did some research and settled on this one - I know it's somewhat overkill and I can't recall exactly what pushed me towards this model. Regardless I appreciate the neat design with the place for the clips. to clamp on for tidy storage. It was ~£185 at time of purchase and whilst not cheap I think it is well worth it. I have only charged this up once and then it has been tucked in my glovebox for a year until today. I'm not sure what happened but somehow my battery ended up completely flat with the engine not turning over at all. Thought I'd try this, thinking it probably wouldn't work... but it started instantly! Amazing! The battery not only has been stored for a year, but has contended with sub zero and over 40°C heat in the van at times. I can highly recommend. This was such a quick and faff-free solution that got me up and running quickly and without help. In a difference situation it could be a lifesaver. I think the GBX45 will be sufficient for most vans however & will save £50 or so.

Handy Product When You Need a Jump Start
Incredibly convenient and easy to use. After fully charging, attached it to my 3 litres diesel vehicle and started instantly, without even having to use manual mode. Really impressive for such a small device.

Great but not quite as tough as they say
Functionally great unit, almost idiot proof. Despite it's tiny size it has started my old Land Rover 8 times before it dropped one battery level. Charged it overnight using a normal usb wall socket no problem at all (and you can charge it from the car when you've started it). Only real gripe is that the plastic protecting the copper clips has already broken on two corners. It doesn't effect the function or safety but it doesn't bode well for something less than a week old. Overall though a great bit of kit

Impressive and gives confidence
We have a 2015 Mitsubishi Shogun 3.2 diesel which my wife loves. My children also have cars and always seem to park them in inaccessible locations before killing the battery expecting the jump leads to preform witchcraft. The thing is with short journeys and loads of electronic equipment in/on the car it kills the battery. My wife and young son have been stranded a couple of times waIting for me or the RAC to get to them due to a dead battery (1yr old yuassa with 5yr warranty, nothing up with it) I've been looking to get something to keep in the car just in case, this NOCO Boost X GBX55 is ideal as its good for all our car engine sizes. I ordered it on amazon (the cheapest place by miles) and expected it to be as good as all the reviews suggest. We'll it was delivered rapidly and well packaged (not excessive) from the minute I opened the box I knew I was in safe hands. Its very well made and of great quality. I have put it on charge and will see how well it performs when my wife or one of the kids next get stranded. I have no doubt it will do its job, some are moaning and I can only assume they have either not read the manual or have other issues. ....Update..... It works, a flat battery on a cold morning prompted a phone call to me from the wife in a panic she was going to miss a hospital appointment. I asked her to look in the boot for the noco booster which has been there forgotten about since we purchased it. Still fully charged might I add.... After a couple of minutes talking through what to do the car was running...Happy wife who said its one of the best things we've purchased. on the evening I just topped up the charge and its back in the boot if needed again. It's an expensive initial outlay but it's worth it in my opinion 10/10 for the noco GBX55, shame there is no hard case available....

Faulty product and no response from NOCO
I bought this product early 2024 and have only use the charger twice since. it is a very good product when charged. however after my second use, the battery went flat out. I tried charging using the charger and I had no luck because it did not charge. I bought other charger recommended for the product and I had no luck. I contacted NOCO via email as I had no other way of charging to see if they have a UK office I can send the product to for checking as nothing seem to charge my charger, I had no response. I am no impressed that a product I bought and cannot charge is with me and out of use. and I am extremely disappointed with NOCO. I would not recommend this product. on the other hand, I made have been sold a faulty product. I had to rate 1 star to submit otherwise its -0 star.

Robuuste en goede kwalteit startbooster. Geloof niet alle slechte verhalen over NOCO, dat zijn uitzonderingen die te veel zijn uitvergroot. NOCO is een van de meest bekende marktleiders in startboosters en maakt zeker geen rommel. Zelfs de Nederlandse ANWB pechhulp gebruikt dit merk! Ik heb met 1x opladen tot 4 keer en zonder enige problemen een 2.0 dieselmotor kunnen starten. Ook een dieselmotor met volledig lege accu kreeg ik gestart met de speciale lege accu functie. Het opladen gaat binnen 15-30 minuten als je een zwaardere USB-C lader met PD en goede USB-C laadkabel met PD gebruikt. (PD USB, oftewel USB Power Delivery (PD), is een universele snellaadstandaard voor USB-C-poorten die apparaten zoals smartphones en laptops sneller en veiliger kan opladen door de benodigde hoeveelheid stroom dynamisch aan te passen.)
