NOCOBoost GB70: 2000A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 8.0L Petrol and 6.0L Diesel Engines

The Noco GB Genius jump starter pack is unbelievable! With the inbuilt technology, it’s impossible to get the polarity wrong as it indicates the incorrect connections and just won’t work. You can even short the positive and negative clamps together with no sparks or damage done. I have a 3.5 litre V6 Mercedes that was left standing with the lights on (schoolboy error!) and it started it as if the battery was brand new. It’s also fitted with a super bright LED array with loads of different modes one of which is a rapid, side to side mode that would be great to place in the road on a dark night to change a wheel. It is fitted with both USB and 12v out and in ports enabling you to charge it off a cigarette lighter or a USB charging point.I realise it may be expensive to many folks but the feel of this thing and the ease of use puts it head and shoulders above everything else. It’s as solid as a house brick!My only slight criticism is its weight as it is around 4.5lbs. I never knew lithium could be so heavy.I hope this review helps with your choice; I cannot recommend it highly enough! If there was 10 stars I’d give them...UPDATE: having owned this for some time I’ve got to know it really well. A pal of mine has an old 5ltr, S500 V8 Merc that wouldn’t start. He keeps it in storage using a trickle charger which packed in without him knowing. I turned up with my Noco, wired it up and it started like brand new. This surprised my mate so much, he rushed out and bought one.One last point, my wife and I are about to buy a camper van and disappear across Europe for a couple of years. Although brand new, I will feel a lot happier having the Noco onboard. Having a camper van not start in some backwater could be a serious issue but would be easily sorted owning the GB70. So, for those with a camper van, put your mind at rest. Why take the risk?EDIT. Buy the carry case too, keeps the unit clean and protected whilst providing somewhere to store the charging leads.

The only jump pack you'll ever need.Fantastic build quality, really easy to use and can start any car you will come across. It charges easily in the car and in the home, with both cables supplied.Leads are short, but they are long enough to position safely within engine bay or battery compartment.Very safe as long as you follow the instructions.

Great unit, got me out of trouble multiple times when my EV 12v utility battery died. Easy to use and great quality.

good product needs charging when delivered. wrong charging cable but fine otherwise

solid quality booster, easy to use,the GB70 is a good allrounder choice.

After reading a few reviews that this item did not work I was unsure if I made the right decision. But with the thousands of positive reviews also I was looking into the main criticisms and decided to give it a go (as I believed a lot of the negative comments could be down to user error, not the product..Things to note:1. Make sure you have the leads are on correctly. (the right way round and connect to the car battery in the order it instructs ) you will know if it connected correctly as it indicates (read instructions!)2. once connected then turn on the device by pressing the main power button AND THEN press the "exclamation mark" ( ! )button - hold for 3 seconds - (until the product lights up once this is initiated)YOU MUST DO THIS if your battery is completely flat (as mine was) - This is a safety override and allows extra boost to start a completely flat battery.My vehicle is a 20-year-old - 3ltr Petrol V6 S-Type Jaguar and it has a parasitic drain that I cannot trace - I do not use it often and it was completely and utterly flat - no central locking (I had to enter using the key) no interior lights would illuminate no sound on turning the key in the ignition - dead!After connecting as above I waited approx 30 seconds and turned the key (I was not sure if it would start..) - IT FIRED UP FIRST TIME!Excellent! - This little boost pack will now stay in the spare wheel well in the boot ready for whenever it is needed - (I cannot say how many vehicles it would be able to start on a single charge but I checked the charge afterward by plugging the device back into the charger and it was still showing charge as on full power)I would recommend this product *****Purchase/Amazon issue: The first product I received via Amazon was a second-hand unit - it did not work, would not power up - it was not sealed and some of the connectors/ items were missing and had marks on it ... I sent this back and received a replacement the next working day- The replacement product was factory sealed and brand new. This is the product I used in the review above.

Excellent, started a couple of cars still got plenty of charge

Kept it charged up as per instructions and the only time we needed to use it, it didn’t work. Had for 5 years and not been able to use it. No good in an emergency, very disappointing. Now we have a traditional lead acid battery jump starter which has been excellent.
