One Jump Starter for 12V Trucks and 24V Heavy Equipment

Published 11/04/2026

Question:

I run a small construction company and we have several diesel work trucks along with some larger equipment that uses 24V batteries. I'm looking for a heavy-duty portable jump starter that can handle both instead of keeping separate units around. Do you have something powerful enough for this kind of use?

Hey Mike, yes we do! I recommend the NOCO Boost Max Jump Starter # 329-GB500 for your trucks and construction equipment. This is a commercial-grade jump starter that works with both 12V and 24V battery systems, so you won't need separate units for each.

It delivers 6,250 peak amps and can jump start gas or diesel engines up to 45 liters. You can switch between 12V and 24V depending on the equipment you're working with, and the built-in voltmeter lets you check battery voltage before attempting a jump.

What kind of heavy equipment are you running alongside your work trucks?

We have a couple of Freightliner dump trucks and a CAT excavator that runs on 24V. Most of our other trucks are 12V. Does the GB500 automatically detect which voltage to use, or do I have to select it?

@Mike you'll need to select the correct voltage on the # 329-GB500 before connecting it to the battery. It supports both 12V and 24V systems, but it doesn't automatically switch between them. That makes it a good fit for your mix of trucks and heavy equipment.
