The GBX55 is NOCO's durability-first upgrade over the original Boost series. XGel battery technology, IP65 waterproofing, and a -40°F operational rating make it the definitive choice for outdoor adventurers, campers, overlanders, and anyone who stores a jump starter outside the climate-controlled vehicle cabin.

I have the gb50 and the volt is only at 12.4. I guess if your going to get the noco, it's best the get the gbx series.

The only downside is that it's designed specifically for 12 V vehicles, so it isn't suitable for larger commercial vehicles requiring higher voltage systems. Overall, if you want a reliable, compact, and easy-to-use jump starter with powerful performance, advanced safety features, and the bonus of a built-in power bank, the NOCO Boost X GBX55 is one of the best emergency tools you can own.

I don't see any thing working. Maybe it's not on a good connection. I guess I mean it's not having a good connection between the battery terminals. Oh, okay. I just did it and it just popped.
