## Description

From the manufacturer aplus content video GBX45 GBX55 GBX75 GBX155

Review: Works every time, and there’s been lots of times. - I bought this in October 2021, after my car battery had run flat at the train station after a weekend away, and the AA couldn’t get to me for at least 2hrs!! I have 3L diesel so needed something with some power. I’ve since used on my car 2 or 3 times, on a work colleague’s camper, and countless other vehicles, and not once has failed to perform. This truly is a great piece of kit, dead simple to use. No drama, no fuss, just does its job. I honestly don’t know how many jump starts it can do. For me, as a rule of thumb, I charge it back to full after I’ve used it, and I’ll periodically check it every 3 months or so, just for my own piece of mind. Expensive, I suppose yes, but the amount of times it’s got people going again, it’s money well spent tbh.
Review: Compact beast with serious punch—starts dead batteries fast, charges gear, and built to last. - Picked this up for van stash and roadside backup—wanted something that could fire up a flat battery without dragging out jump leads or waiting for help. The GBX45 delivers. 1250A peak current is no joke—started a diesel van and a 2.0L petrol car with zero drama. No sparks, no hesitation. Lithium build keeps it light, and the casing’s rugged—feels like it can take a knock. USB-C input/output means it doubles as a power bank too—charged a phone and a torch off it while camping. LED light’s bright enough for night work, and the clamps are solid—no flex or cheap feel. Good stash-ready gear for anyone who wants peace of mind on the road without the faff. 👍 Pros ✅ 1250A peak—starts most cars and vans easily ✅ USB-C power bank—charges phones and gear ✅ UltraSafe tech—no sparks or reverse polarity risk ✅ Compact and rugged—easy to stash in boot or cab ✅ LED work light—handy for night use or emergencies 👎 Cons ❌ Premium price—worth it if you want reliability ❌ No hard case included—store carefully ❌ USB-C cable only—no wall charger in box ❌ Not for heavy-duty trucks—check your engine size 🧭 Personal Review If you want a jump starter that’s compact, powerful, and built for real-world use, the NOCO GBX45 earns its spot. I’ve used it across van setups, roadside calls, and weekend trips—no drama, just clean starts and solid backup. Proper stash-ready gear for anyone who wants their battery sorted and their gear charged.

## Questions & Answers

**Q: Is it safe for motorcycles?**
A: Yes, but only if the motorcycle has a 12v battery (99% of modern motorcycles do). Some older bikes use a 6v battery and might be damaged using a 12v booster.

**Q: Not charging totally dead only used it once.i want a refund**
A: I do not know for sure.
I speculate this type of device can easily start a motorcycle size battery but would have difficulty starting a 3 litre car size battery.

**Q: charger bar wont go past 2 bars**
A: How are you charging it - and for how long?  It can take many hours with a slower, older charger.
No issues here.  I just checked mine that had been in storage for about a year and there was one light not showing which I was very pleased with.
No way is the one I have fake.

**Q: Would this be allowed in my carry-on case?**
A: Yes, the boost must be in a carry-on it cannot go in checked luggage
