Great deal. This was arguably the very best unit in Torque Test Channel's test a couple months ago: https://www.youtube.com/watch?v=z4N5txe7oZA

I think this one is more powerful than my GB50, I believe the 1750A version is more comparable to this. I'm surprised it wouldn't be able to start a diesel though.
This unit displays something along the lines of an E2 "over current" error.

Just curious is that with the boost mode on? I noticed in Project Farm's video it also struggled to start a 5.9 diesel but I couldn't tell if the boost mode was on.

I'm not sure. Haven't personally tried it. SlickRain1963 might have some input.

Don't see item lists safety features on its description such as spark-proof, mistake-proof, reverse-polarity protection, etc...
Never tried, but will it spark when you accidently have the clamps touch?

Can confirm, just tried it this morning and it will not start a diesel.
I also want to say that I tried my Gooloo on my dead ram 2500 with the 6.7 Cummins and these do not work. The problem is the truck heats the glow plugs every time you try to start, even if they are already warm. Consequently the glow plugs kill the starter before it even tries to turn over the engine.

That's the one to buy for the most versatility and it was just $55 AC last Nov:

That is the one I bought too and can't see why this would be that much better but thought I would ask.
