## 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.

### ⭐⭐⭐⭐⭐ My 2nd NocoBoost. They last a LONG time and perform great when you need them.
*by J***D on February 28, 2026*

I own a NOCO GB40 that has lasted many years 7 I believe. It is time to retire it finally. I use it for work at a small dealership and it never fails. One thing I will note from another review is that it WILL activate if the vehicle battery is totally dead. You have to hit the Boost / Override button. There are no real instructions with this unit, just a warning book in several languages. You can find user instructions under support on Noco's website. Just select support / boost jumpstarters, then your model. The unit is pretty self explanatory except the "boost" function. I expect to get many years out of this GBX45, and it has a few extra features. USB-C charging In-Out is a plus, as are the extra light modes. That being said the GB40 has started everything that I tried it on. I use this probably more that most customers will. I did have to replace the jump leads on the GB40, but this was after over 5 years use and rough handling at times. When not being used for work, it resides in my trunk. I have never needed it for my personal car, but I have helped several others over the years. There are several other devices on Amazon that are less expensive with more power supposedly, but why chance it when I know this one should last many years like my last one did. I also buy from trusted brands only when it comes to rechargeable lithium batteries of this size. It is not worth a fire risk to save a few dollars! Cheaply assembled Lithium batteries are noted for overheating while being charged. At work we have had two that swelled to the point of being unsafe to charge. Not the NOCO.
