NOCO Boost HD GB70 2000A UltraSafe Car Jump Starter, Jump Starter Power Pack, 12V Battery Booster, Portable Powerbank Charger, and Jump Leads for up to 8.0-Liter Petrol and 6.0-Liter 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.

Very good product

When it works, this jump starter is brilliant—plenty of power to get a dead battery going, even on bigger engines. I’ve used it a couple of times and it fired up the car straight away with no issues.Feel sturdy strong and durable has a nice carry case.Liked the safety feature that you can’t damage the NoCo or the battery if you place things the wrong way round.The downside is that it doesn’t hold its charge as well as I’d hoped. After a couple of weeks in the car, it had already discharged quite a bit. Not ideal if you’re relying on it for emergencies.Great for regular use or to keep topped up at home, but probably not the best choice if you want something to just sit in the boot “just in case.”

I bought a small jump starter before this one and it failed to even produce more than the familiar click you get when you have a dead battery. So I realised I needed one that was going to be adequate for the job in hand. Reviews and comparisons that included the NOCO GB70 were very positive and it came out on top. I ordered it and it arrived (about 50% charged) the following day when the battery in my 2.2L Range Rover Evoque (diesel) was completely flat again. It started it first time. I then had to start it a second time 30 mins later to get the car to Kwifit for a replacement battery. Again it started with no problem without even charging it.This is a heavy duty piece of kit which is very solid and well made. I am really pleased with it so far. The only negatives are that it takes up to 7 hours to charge via the USB connector provided. There is no mains adapter provided. This is not a reason not to buy it however as you do have a option to charge it from a cigarette lighter in the car (while you’re driving about ). I put the NOCO on charge via the cigarette lighter when I drove to get my replacement battery and it was 3/4 charged an hour and a half later. A second small point to mention is that the powerful integral LED light would be better placed at the opposite end of the unit so it points to the battery terminals rather than away from them!As it stands today I would highly recommend it.Additional info that may help....I also bought a volt meter that plugs into a cigarette lighter so you can monitor both the battery charge when the engine is off and with the alternator output while the engine is running. You don’t need to be technical to plug the meter in to see you have 12+ volts with the engine off and 14+ with it running. If it’s gradually dropping from 12 volts in normal use, the battery may be failing to hold its charge or the alternator is not charging it but bear in mind that multiple consecutive short journeys, with everything turned on in winter, will pull more out of the battery than the alternator can put back in.

Excellent piece of kit quick and easy to use
