NOCO Boost X GB75: 2500A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 8.5L Petrol and 6.5L Diesel Engines

Am tired of long jump leads floating around in the car and having to hope there is another battery to jump start something from so thought id buy one of these. Expensive but its always handy anytime I need it. Takes ages to fully charge but the charge holds for ages too so cant grumble at that. Very powerful, literally I put it on a completely flat battery, walked to the ignition and turned the key and it started first time, literally on there seconds !!!

Remarkable product, my battery was flat I connected this product to my car and the engine started within a quarter of a turn. Very well built.

Amazing product will start anything any time highly recommend started a works 4l truck no problem

I purchased this with the hope that I wouldn't actually need it... but it turns out I did need it and boy am I glad I had it.My campervan's (VW Transporter) battery died and I was stranded in the middle of nowhere. Luckily I had the NOCO GBX75 and after reading the fairly simple instructions I had it connected and the van started in no time. I am by no means mechanically minded, but it was so easy to use. There was also the added benefit of having safety protection in place which meant I was safe in the knowledge that I couldn't do real damage if I did something wrong.I even took my van to a well known brand garage, and whilst it was there the van battery failed and wouldn't start. They tried jumpstarting it with the equipment they had and couldn't. When they told me, I got the NOCO GBX75 out and started it straight away! The smug look on my face, and the embarrassed face on theirs was almost worth the price itself!

I’ve had this product for 12 months almost it’s seven days before the 12 month warranty is up. I’ve treated it perfectly and charged it within the guidelines. It’s been very lightly used. As of today it will not take a charge. From previous reviews I’ve heard this is an issue, they do not make it easy almost impossible to contact them directly except for leaving this review. I don’t even know how to do it. Hopefully someone from the company will contact me through this. It’s been a great product. Butt has failed prematurely in my opinion, only in Maldives and yeast within the guidelines.

It’s about time I write a review on this product. I use it every day four or five times a day as I do roadside breakdown. It’s a really powerful unit. Easy to use. There is only one downside to using this product. If the battery is fully flat that’s 0 V you cannot use it. The battery on the vehicle must have about 3.5 V in the battery to initialise the jump pack. I have started 1 L up to 3 L with no problem well my products.

Initially purchased to assist in starting a problem van as a temporary fix prior to sorting permanent solution.Very portable and allows for easy jump starting of a vehicle if battery is flat.Its been used on 3 different vehicles in very unexpected and different situations in as many months - who would have guessed it would be used so often.

Opened it, charged it used it. No issues here.
