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

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.

Amazing device. Do all what suppose to do

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

Brilliant bit of kit.

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 had previously used one of these NOCO jump starters when we had some freezing temperatures a few weeks ago and it got my wife's 1600cc car started in the first attempt. I was so impressed with it I decidedto buy one for my 3 Litre car. Amazon delivered it for me the following day so we are both covered in the event of a flat battery or more freezing weather this year in future winters. Very pleased with the NOCO product and the Amazon overnight service.

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.

Brilliant bit of kit
