NOCO Boost Max GB251: 3000A UltraSafe Jump Starter – 24V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 32L Gas and Diesel Engines

It's been a rough winter in North Dakota. Freezing temperatures left our truck batteries not wanting to hold a charge. This is heaven sent! No more waiting all day to jump them off of our pick up trucks battery. This works very quickly but one jump and you have to recharge it. It takes about 3 hours to fully charge. We use it for our 2015 Pete 579. It fits nicely in it's case and it's not as heavy as I expected it to be.

N/A

I received this item and opened it out of the box, and plugged it in to start charging it, it went to error after 30 seconds of charging, and would not charge anymore, returning, it’s crazy to pay this Much for the unit and it will not charge.

Every car owner must have

Worked exactly how it was supposed to.

Only used twice, but worked fine each time on large 24v diesel cat engine. Leads are a little short, which makes it harder to find a spot to put the booster while boosting. Case is really nice, like nicer then it needs to be for what its purpose is.

Works every time

I work for a major transit company as a bus mechanic. Grabbing the giant battery cart and walking it 300 yards to find the cart batteries were dead started to become frustrating. Got one of these on a good deal of the snap on truck. Jump starts Cummins 8.9L all day while only showing 4v on house batteries.
