FLYSAIL Car Jump Starter, 800Amp Car Battery Booster Jump Starter for Up to 6.0L Gas or 3.0L Diesel Engine,12-Volt Portable Jump Starter Power Pack with Smart Clamp Cables, USB Quick Charge, Kit Bag

I bought this and it started my 2016 diesel that had been sitting for 6 months unused. Then it saved me again after a battery problem led to another day of non startingI bought another model which was more $$$ that did NOT work. Managed to dig this little badboy out and boom I'm back on the roadEven if I don't get much more use out of it.Zero complaints from meThe only gripe is the leads are too short. Wish they were longerTop notch item

Not used it yet looks the part.

Product as discribed although not used in practice yet. Use as a standby if required?The package was open/damaged? Photo taken.

This item wasn’t cheap but not the more expensive of devices. Came almost 75% charged and rapidly went to full charge within minutes. My car battery completely went flat due to freezing conditions and non use over a month. At first, I tried to jump start the car via another car and it didn’t do much.. then I charged up the car battery a little and then used the device after a few cranks and smoke.. I was back in business. Highly recommend this item. Can use this item to also charge USB devices standalone and has a bright torch.

Bought this as I had an intermittent fault on my battery and couldn't get it to the garage for checking for a couple of weeks. Very surprised at the small size and worried it wouldn't work but WOW ! From a totally flat battery to starting and it still had enough charge for another three boosts before needing charging. It can even be charged via cars 12v socket so it can be topped up whilst on your journey. Comes with a selection of phone chargers to so could be used whilst camping as well.

I have used this 3-4 times already on various cars (1.9 Diesel, 3.0 Petrol engines) and it worked fine. So cannot complain at the moment. Let's hope it stays that way, not that I intend to use it every 5 min either...Easy to use, light, and it works, so what's not to like?!

2 hours for 25% charging more than 7 hours for full charge. I have a trust in Amazon hope Amazon will solve this issue.

Great product.If you do not use your electric car regularly, the 12 volt battery that supports the electrics eg alarms, etcwill run down. This starts the car with the jump leads supplied, brillant torch, ports and leads for iphones, etc
