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.

I haven’t touched my car for around a month until about 2 weeks ago. When I attempted to start it, I was having issues and it was not working properly. I had someone check and turns out the battery had died and I needed a jump starter. I purchased this and hoped it would work properly. When using it was easy to use, the lead length was good, I was able to easily use this product to jump start my vehicle with enough charge. It is a little heavy however for the build quality it is good. It comes with a bag and will be stored in the back of my vehicle incase anything like this happens again. Would recommend.

Very good jump start unit. Holds charge very well. Started my Ford 3000 tractor after being parked up all winter with a dicky battery.

Works a treat well worth it

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.”

Initially bought a smaller one …returned it with no problemsIt is very easy to use and has started my Campervan on numerous occasions when I have left the headlights on etc

Delivered fully charged, did what it was supposed to in seconds, it was perfect! Really happy with it and recommend it to anyone that is considering buying one!

Arrived with 25% charge, and was immediately fully charged up via USB until the top green light was on, indicating completely charged (unlike some other comments, it was fine fully charging via USB, although this took a few hours).Connected to the battery in my van (Renault Trafic 2.0 diesel).Turned the ignition key - and nothing, not even the instrument panel, came on.The only thing that happened was the Boost HD white LED on the NOCO turned on and off, accompanied by a clicking sound (no explanation in the manual of this behavior).Took the NOCO indoors, checked again it was fully charged, then tried my vehicle again - this time along with activating the manual override (press the "!" button for 3 seconds) - again, absolutely nothing - not even the instrument panel in the vehicle came on.I checked the vehicle battery with a known good voltmeter - and it was down to 3.8V - very low, but within the parameters of what NOCO claims it can start.I suspect the NOCO either has faulty lithium cells (which must be rather specialized to be able to deliver the rated current), or it has faulty high current circuitry (is there a high current relay in there that is clicking?).Whatever - it's not my problem to solve.It's NOCO's job to deliver a product that does what it claims - jump starting vehicles - or otherwise it's just a very expensive torch. The NOCO appears very substantial and physically of quality - it just did absolutely noting for starting my vehicle.I sent the NOCO back, and instead bought a CTEK MXS 10 charger - which has been able to fully recover the vehicle battery (so the vehicle battery is not defective) - and my van then started instantly on the first tweak of the key.The battery in the Renault Trafic is awkward to remove, and I don't have mains power where it's parked - so a jump starter was the most convenient solution - but the NOCO has proved useless in this case. The CTEK charger has now proven itself - it's very, very obvious why I avoided the NOCO chargers - I've had a big loss of confidence in NOCO products.
