NOCOBoost 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

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.

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.

Excellent battery booster / starter. I’ve tried others but this one is by far the best

Worked immediately after van left for 1 month without being used

Brilliant product but would like a little more detail about how to avoid the cancer / reproductive harm risk?!! Is this from general sensible use or just if I break it open & try to eat it?!!!

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

I bought this because my vehicle battery completely failed down to 0/5%. I did a bit of research online and found someone else who had a similar issues who had a similar problem whilst away on holiday and bought one of these and jumpstarted the vehicleeight times until they got a battery. I was about to get recovery to take me to the garage and realised it would cost me a small fortune for them to come and use one of these devices to get me going so got this one after lots of reading and it started like a dream the day I needed it to take it to the garage to get a new battery. It started the van on the day and saved me the recovery costs. Will keep this in my toolkit for that day when I stay somewhere too long and I run the batteries dry and it gets me out of trouble. Will update in the future if anything changes but this simply did the job. Really easy to connect through the engine engine portal on the right hand side and the negative can be anywhere that’s metal so comments about the leads being too short don’t really make sense.

I have a motor home with a 2.3L diesel engine which - depending on the time of year - can be parked up for a good few weeks at a time without moving. I got this because I was worried that I’d rock up at the compound during the winter months when the solar panel may struggle to keep the batteries charged and I’d struggle to start the van with a flat battery. It’s not happened yet.What did happen ( I now know ) is that the cab battery suffered cell damage so whilst away ( far, far from home) I couldn’t start the motorhome. Every time I needed to start it, I used the GB50 and it started in a few cranks. The alternator was generating enough leccy to keep the engine running once it was started but the battery couldn’t hold enough charge to start the engine. So each time I turned the ignition off, I used the GB50 to restart the engine. This means fuel stops, waste water dumps, stalling (?) etcSo I reckon I used the GB50 maybe 7 to 8 times before I got it to a local place that could diagnose and swap the battery out. Performed brilliantly. If I didn’t have the GB50 it would have been a recovery job and I’d have to cut the holiday short. People weren’t always around to give a jump start.So yes, if that battery is as ‘flat as a witch’s tit’ it’ll start it but also if the battery was totally bust like mine then it *still* started the van.I’d rather not be in the position to have to call on the GB50, but when I needed it it saved my holiday. So now I’m an advocate 😃What I would say though is that the distance between the HD leads is only good enough to reach between the posts of your batteries. In my case, I used specific designated jump start points in my engine bay ( Fiat Ducato - you must not jump start via the main battery due to ECU issues ) and these jump start points are further apart than the supplied leads will go so I used a jump lead as an extension to the HD leads as supplied. This shortness of terminal HD lead is the only grumble that I have.
