I think it's better to buy an $80 version of these, not sure why this one is worth so much. A few extra jumping amps?

Watch the review by project farm on YouTube. I'm very reluctant to buy one, but it is the best one available in 2023.

Many times it seems these jump starters purposely underrate the size engine they can handle to upsell.

I've used a $30 jump starter from TEMU and it works just as well as my $100 NOCO. It says rated for up to 2.0L engines but I've started a 4.7L V8 without any issues.

I'd buy a lower model and test it before spending too much, unless cost isn't a concern, in which case, have at it hoss. That said, I've also started questioning NOCO quality the past couple years. I had the battery on a slightly older but rarely used jump starter bloat, and a brand new Genius charger malfunction after the 2nd use : / Yes, this is anecdotal, but worth considering.

I also watched the Project Farm video. Most jump starters did not perform as advertised. The NOCO GB 155 was the class of the field. Starting larger diesel engines requires a lot of power the cheaper jump starters will leave you stranded while the NOCO crosses the finish line.

I have been a noco fan for a while
I personally got one for my dad, gb70. it worked great for a few years. I can't remember exactly when I bought it but just recently it started to give him problems. it shows that it is fully charged but it will not turn on when it's time to jump a vehicle.

also, I purchased a gbx155 for a family member during Black Friday on amazon in 2022. Luckily he told me that his did not want to charge at all a few days before his warranty expired. I immediately did a warranty claim and noco sent his replacement. Overall a good experience but I guess he got lucky that it died a few days before the end of the 1 year warranty.

I started searching on the gbx155 issue and apparently it's a known issue.
