NOCO Boost XL GB50 1500A 12V UltraSafe Portable Lithium Car Jump Starter, Heavy-Duty Battery Booster Power Pack, Powerbank Charger, and Jump Leads for up to 7.0L Petrol and 4.5L Diesel Engines

I bought this to primarily use with my Aprilia RSV1000... an old Italian 1000cc V-twin motorcycle renowned for starting issues in cold weather unless your battery is perfect (and I have a Noco Genius10 looking after the admittedly pretty old AGM one on this) and/or that you use the bike frequently.To be fair, this is overkill for this application given its claims to be able to crank an engine six times the size. And so it would prove. Every time I have left the bike for a couple of weeks out in the cold weather and it has refused to start under its own steam... I plug this in (using the highly recommended - if a bit expensive - Noco GBC007 cable if you also use a Noco Genius charger... but a Noco GBC002 will do if you don't) and as sure as eggs are eggs, it will start... even on those horrible 'wide open throttle' long cranking starts, this thing does the job easily. There appears to be way more than enough cranking amps available as the starter spins fast and long and the engine really doesn't have a choice but to fire.As I said, it may well be overkill for this and it's likely that the bike isn't really testing this at all... but in this application, this guarantees a started motorcycle. From fully charged, I've used it maybe a dozen times and it's still showing a green charged indicator so it's definitely not really being challenged. On a 3 litre diesel, probably a different story.Hard not to recommend it though. Easy to use. Compact. Looks the part. Starts the engine. Job done.

Great booster and works well.Tip: I connected the booster to my car battery and it would still not start. I eventually had to charge my battery and only discover afterwards, after watching a YouTube video; that if your battery is too flat, the booster will not tegister your battery on the first setting.Press the RED exclamation button and it overrides the 'protection' features and supplies a boost past the battery and directly to the starter which then starts your car.

Started my truck with no problem after the battery died overnight. Compact and easy to use. Holds a charge well and feels solid. A great backup to keep in the car.

I was going to by the 90 model but I like overkill so I went for the XL. I'm actually quite glad I did.I read the instructions and plugged it into my USB charger. It took 4.5 hours to charge which is I think what the instructions said it would be.I have always been a bit sceptical of these little car starters because they look so small compared to the big lead acid powered ones of old. But it does do the job and it does it pretty well. I was convinced when a friend told me that his "90" model started his 5 Litre AMG Merc but all the same I wanted the extra comfort zone for my high compression 4.2 Litre Audi RS5 so I bought this bigger XL model. This model is supposed to be able to start an 8 Litre car. Three times.It does the job perfectly, however I would question its ability to do it three times in a row without charging. I think that's pushing the boundaries of belief. For example, on my 20 HP Briggs garden tractor engine, the thing was flat after three 10 second cranking sessions. But crank it it did and had the petrol been actually going into the engine <grin> it would have started. And I've no doubt that as soon as I clean out the crud from its 20 year old carburettor, it will...I also bought the optional carry case which is a nice design and this whole thing will fit nicely in my glove box until it is needed.I only have one slight complaint: The crocodile clips to connect the battery ought to be on a longer leash. On a big engine you have a big battery and opening these out to the full extent of their Y makes it a very tight stretch on my battery.

Hi, I have received the item in good time and good condition, however there is no plug for me to charge the buster, I have a cable which doesn't fit anything that I have, how am i supposed to charge this item.

THIS DEVICE HAS SAVED ME LOADS OF TIMES AND EASY TO USE AND ALSO CHARGES PHONES ETC HANDY TO KEEP IN THE BACK OF THE CAR OR VANBUY ONE

Great piece of equiptment. Have used it a rew times and it does the job effortlessly.

This is a great tool to have handy , my car battery went flat...i tried to jumpstart it off a fully charged 95ah lead battery i had in the garage...and it really struggled! i even tried a second battery. unsure why but i just thought il get one of these as i have an automatic its always worried me.I intentionally drained my car battery totally flat till the point the door couldnt unlock and then clipped this on...and it started no issue.It took 5 or 6 cranks but it got there in the end on the first go. and all this and the battery level didn't move off 4 bar aswell so it probably has another 4 or 5 cranks in it at least.Used on a audi a5 2.0 b9 2017 car
