## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Compact beast with serious punch—starts dead batteries fast, charges gear, and built to last.
*by G***E on 21 September 2025*

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 ReviewIf 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.

### ⭐⭐⭐⭐⭐ Just keep it in your car and you’ll never get stuck anywhere, plus you can always help others out.
*by S***N on 30 April 2025*

It works, buy it !!! This is an excellent bit of kit, it will start your car up with a completely flat battery with no effort whatsoever. It’s very small and packs in your glove box if you so wish. It’s so easy to use and changes up from a USB point so you can charge it while you’re driving. Don’t be fooled by its size. Would definitely recommend.

### ⭐⭐⭐⭐⭐ Rugged booster with easy to understand UI.
*by B***D on 16 May 2025*

This Noco Booster is more expensive than equivalent products but the cost is justified by the rugged design and solid build quality and comprehensive UI provided by the various Indicators on the top of the unit.It is easy to use thanks to the modular design which allows the battery clips to be separated from the booster unit. A significant upgrade from the older and heavier lead acid based jump starters, being lighter and taking up much less space. Being able to recharge via USB-C makes the product much more flexible with no booster specific charger or cable to lose or break.After boosting/jump-starting a 2.0L petrol engine the booster seems to be at 2/3 capacity and takes 1-2 hours to charge back to 100% with a USB-C laptop charger.
