Review: Great jump starter - Purchased this as we have many things that may require a jump start. It charges quickly and is very easy to hook up and jump start anything we need it for. It is a nice, compact size and comes with a carrying case. It works great and we would highly recommend it.
Review: It will Jumpstart a firetruck - Really impressed with this jumpstarter. I have owned this for a few years and have used it on various vehicles, it always works effortlessly. However a few weeks ago I had to put it to the real test. Our fire engine at my job had not been plugged in the night before and was reading around 7.5 volts on my meter, it wouldnt even turn over. It was a Sunday so no one was avaliable to come out and work on it. I figured I would give my noco a try. Our fire engine has an L9 Cummins with 4 giant batteries. I hooked it up and hit the boost button, waited a few seconds and started the truck. It fired right up! The noco had used about half of its battery and had the temperature light flashing for a while but it was able to do it. Once it cooled down it charged right back up. I wouldnt recommend doing this everyday with this sized battery, but it definitely has the beans to do it.

## Questions & Answers

**Q: BG45x is there a storage case for this model?**
A: The GBC101 protective case just released, and it is specifically designed for the GBX45.

**Q: What’s the difference between this and the ultra safe?**
A: The all-new GBX Series Boost X features NOCO's latest PX Lithium Technology allowing for maximum power delivery and faster recharge of the unit's internal battery. It adds in a 60-Second Timer to conserve power when jump starting. The GBX delivers more power and can be recharged between each use quickly with the new USB-C Fast Charge feature. We replaced the 12V XGC port with a more powerful USB-C port, capable of powering devices at 60W such as laptops, phones, and tablets.

The GB Series Boost features USB charging on all models with 12V fast charging available on the GB70 and larger models. The GB series can power USB devices up to 2.1A with the GB70 and larger models able to power 12V devices up to 15A via the 12V XGC port. Additionally, the GB70 and larger models can also be fast-charged using the NOCO XGC4 AC Power Adapter.

**Q: Can this be traveled by plane? I want to take one to mexico.**
A: 1) not allowed in checked baggage.
2) must be placed into a LiPo bag when in carry-on (these are available on Amazon) - these bags are designed so if a lithium ion battery gets overheated and transitions to a runaway state, it doesn't affect the other batteries you're carrying and or explodes (at least that's the goal).
3) Each airline has different rules for the individual and cumulative amperage for lithium ion batteries in carry-on baggage. These rules typically apply to a single bag, so if necessary you could distribute the batteries in multiple carry-on bags - and be aware, especially when traveling internationally, some airlines will make you pull out all the batteries and look to confirm that they're in the appropriate LiPo bags.

**Q: What is the mAh rating for the internal battery?**
A: Noco GBX45 ---- 8,600 mAh (milliamp hours) @ 3.7V (nominal cell voltage) = 31.82 Wh (watt hours) of battery capacity.

Equivalent to 2,150 mAh @ 14.8V (4 * 3.7V cells in series) = 31.82 Wh.

### ⭐⭐⭐⭐⭐ Just Buy it, its completely worth it
*by T***S on April 27, 2025*

Just go ahead and buy it, it’ll save you one day trust me. Let me tell a little true story basically I’m a bass head and I wanted a sub in my jeep so I took the kicker sub and amp I had in my truck and put it in my Cherokee unfortunately we did not reconnect the cable that travels from the alternator to the battery bus bar however the cable was on the post, the first sign of the problem occurred when the stop/start system was disabled shortly after driving away. I thought this was because the car detected the subwoofer was now drawing power so it disables the system so I ignored it. We did all this on Saturday evening and everything was going smooth, Until “Wednesday” came around. So I’m driving to work on the interstate in the first three warnings that came appeared were ABS, Stability Control, and my parking brake were all disabled. Forgot to mention my card did start mentioning something about a low power state but I didn’t know what that was about but now I know; Anyways I stop at a red light, and things start to get real problematic first my AC starts turning on and off and then my head unit blacked out. I put the card in park because I didn’t know what was going on. I opened the back of my jeep manually as the Rear powered door is also disabled. I glance over at my Subwoofer Amp (Kicker 800.1) and I see two lights on at the same time power and protect meaning the voltage in my car battery was below 10 1/2 V and I verified that with my multimeter as I work with AC units so I jumped my car battery off with a little bit of voltage from the pack and I was able to quickly get to work in the afternoon. It turns out I did not reattach the nut nuts for the battery lead meaning the car battery was never truly charging. If you’re thinking about buying a cheaper, one of these, you might want to stick with this brand as they are very reputable charge very quickly through USB-C power delivery, which is very handy. It is in my opinion the safest jump pack as you cannot short the output unless you override the pack, which I have done before sorry about that Noco, but I had to experiment. Sheep was work, but they’re usually made with cheaper batteries so they don’t hold a charge very well and they die pretty quickly so it might be only good for six or seven cranks. This jump pack also has many safety features and temperature protection. And it has a flashlight. I don’t know what else to say but I strongly recommend buying this jump pack. It’ll save you when you’re in a jam and it saved me from being stuck at a green light.
