Review: Brilliant, powerful booster. 👍🏻👍🏻👍🏻 - I was a bit sceptical about this after calling the AA to start my Transit Custom about 6 times because of a battery drain somewhere, they struggled to start it with their booster. I ordered this and was amazed on how quick it started the van from completely flat, I couldn’t even open the doors with the central locking because it was so flat, put this on the engine earth and live terminal under the bonnet, really easy, then turned the key and it fired up instantly. I’ve used it twice now without having to re-charge it, I’ve also used it to charge my phone and it has a handy torch too. It’s excellent!!! Well worth the money.
Review: GREAT BIT OF KIT! - Great bit of kit, was skeptical at first. Been having issues with my battery in my Vauxhall Grandland X. Recently had a brand new battery fitted but battery keeps going flat after no use after a few days, possible alternator issue. Car wouldn't even get going on jump leads. Tried this on first attempt and didnt start, however it did try and turn over. What I didnt realise is, once plugged in, ALLOW MINIMUM OF 60 SECONDS before trying to start the car to allow the battery pack to pump some juice into the battery. Once I tried this, car started first time! One thing to note is that it will only jump start your car once before needing a recharge. But all in all, a great bit of kit in an emergency situations.

## 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

### ⭐⭐⭐⭐⭐ 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 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.
