NOCO Boost X GBX75 2500A UltraSafe Car Jump Starter, Jump Starter Power Pack, 12V Battery Booster, Portable Powerbank Charger, and Jump Leads for up to 8.5-Liter Petrol and 6.5-Liter Diesel Engines

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.

Great piece of kit

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.

Connected it to a car and it started smoking and set on fireWould not recommend at all I don’t even know if I have any warranty on this can’t find anywhere that says it has itIt was very lightly used barely ever used it I’m not using for commercial just personal use

This is the second booster pack i have bought, my first one is the bigger version with 4500A i have had it just over 2 years now and works fine, i bought this as i am sick of looking for mine because someone has borrowed it. Providing you keep it charged im sure it will not let you down, i only ever slow charge mine and can take 48 hours but well worth it and its always ready.

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.

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!
