NOCO Boost X GBX155 4250A UltraSafe Car Jump Starter, Jump Starter Power Pack, 12V Battery Booster, Portable Powerbank Charger, and Jump Leads for up to 10.0-Liter Petrol and 8.0-Liter Diesel Engines

Have been using it for the last 6 months, so far its already paid itself off, jumped a couple of cars from I4 to V8's and it handled every single car with a breeze. Always carry it with me in the car. Battery can be used several times before it needs to be charged (Depending on the engine size & temp), just wished the portable case that's sold separately would have come with it as standard instead of the provided soft cloth pouch. And no charger is included, you will need to get the charger separately if you do not have one.

Excellent every body should have one can’t go wrong

Mine has arrived and is faulty, the amazon link sends you to the noco page, the service is awful and they are hard to get hold of, DO NOT BUY!

Excellent it off kit never let me down yet, use it a lot, farm tractors ect, could do with longer cables there is often no place to sit it on some tractors close enough to starter or battery

Bought this back in August and it has proved to be a great bit of kit, starting everything from our 1 litre Nissan Figaro to our Hummer h2 v8 6.2 lire, and everything in between. even totally dead batteries can be jumped, so impressed i've now bought a NOCO Battery charger

The media could not be loaded. So from the top I have a 3.0 diesel 4 cylinder Toyota Land Cruiser and it’s been a solid car run general but that car has been stood for 2 year with failed attempts at jump starting this thing has 2 battery's on but at one point I connected a van and car up to both batterys trying to jump start it no luck using this 4250amp booster on the primary battery it got that engine ticking over first click so yes it does what it says that all there is to say your viewing this jump start because you need a jump starter we’ll GET THIS ONE TRUST ME (reason for 4 stars it should have came with a fast charger for the price)

I purchased this Jump Starter pack for my 2.2 313CDI Mercedes Sprinter. I have purchased other cheaper packs before and found it to be a false economy as they rarely worked if left for a day or two after charging.This GBX155 starts my van even after being not used for a month and also at a faster rate than the van battery ever did, even when it was new.My friend is a farmer and uses the same pack to start his tractors.I absolutely love this product including the light so jumping in the dark winter mornings is no problem.The only disadvantage I would say is the weight, It's not lightweight, but wouldn't expect to to be to jumpstart large vehicles.

Bought this for an old Jag 4.2, super impressed how well it spins the engine over, should start anything that’s capable of starting. Seems to have plenty of reserves for quite a few attempts
