NOCO Boost GBX75 Jump Starts a Pickup With No Battery Connected

I have been needing a new jump starter but there have been none that could handle my diesel truck or even some of the smaller displacement engines in our other vehicles. I had been considering the previous generation NOCO jump starters but still wasn't completely sold. Now, with the latest version and the capabilities the NOCO GBX75 has, I thought this might be able to start something with larger displacement. Additionally now that it can be charged using USB-C it can also be used as a large powerbank. I tested the included adapter to confirm that it does charge it at the advertised 60 watts and it is right at the specification. The light is very bright and should be very helpful when looking for the battery terminals in the dark. I wanted to create a worst case or at the very least a difficult test to verify the capabilities of the jump starter. Since none of my vehicles currently has a really degraded battery I decided to disconnect the battery on an early 90s Chevy pickup (4.3 liter V6) that hadn't been started in about 8 or 9 months. Although this is a smaller displacement gas engine I thought this would be comparable when my diesel trucks batteries get weak. Typically when my diesel truck has difficulty starting is when both of the batteries are down to 50% of the original capacity or essentially one battery (800 CCA). The Chevy uses a 750 CCA battery so I'm reasoning that this would be somewhat representative. In order to jump start when there is no detectable voltage you must press and hold the "OVERRIDE" button which has a red exclamation point (!) on it. I have included a video showing the jump start. Once I engaged OVERRIDE the ignition chime in the truck started as it normally does. The truck started as if there were a battery connected! I was pretty shocked at first but in a good way. I tried it another time the following day and I got the same result. After having completed the two "worst case" jump starts the battery showed three out of bars of capacity from a full charge. (Before I tested the unit I charged it to 100%.) So I imagine that it could do maybe 4 to 6 more jump starts of this difficulty. This is great because sometimes you may not be able to get a battery replaced immediately or fix a parasitic drain from a vehicle short. In this scenario I could continue driving as normal and recharge the jumper as needed. In short I definitely recommend NOCO GBX75. None of my previous traditional battery-based or lithium-based starters could handle this test.
