WOW Jump boxes

[Dave O]

Unfortunately that one is no longer available but I would have to hope the technology has improved after all these years. So I'd look for something much newer if I was in your shoes. If you happen to be from the Long Island area I'd be happy to let you try it and another newer one I have for another car to see if either is powerful enough.

Thank you Steve I have a WolfBox 4000A in my Maverick but haven’t had the need on the Motorhome just thought if someone had any experience jumping a large diesel engine I might consider buying a JumpBox for that application

They're great!

I have a hulkman one,

https://amzn.to/4aydnk6

that I've had for the last few years.

I make sure to discharge them (by bringing them inside and charging other devices from them until empty) and slow charge them a couple times a year. I had some generic one years ago that ended up dying because I just left it charged up and unused for years. LiPo batteries don't like to be stored at 100% for years.

FYI. LiPo have a self discharge rate and should be topped off every few months.
ETA:You could plug the charge input USB wire into a USB charge port in your truck as the noco internal BMS will not over charge its battery.
The gb40 comes with Cig style USB plug that out puts 5v2.1w so it's USB wire can be used in any USB that has that output.

I thought these were a joke but we got one at work and it never failed to get a truck going, it would even start the diesel. I got one on a black friday special for $80 and keep it under the back seat.

I thought the same thing until I tried one and the rest was history lol

I wonder if the jump box you show would crank my Cummings diesel Motorhome?

Dave,
I'm thinking the one that I have would probably work for your diesel according to the description.
I did have to buy a larger amp charger in order to charge the jump box to 100%

The GOOLOO GT4000S is a 4000A peak, 12V portable jump starter capable of starting engines up to 12.0L gas or 10.0L diesel. It features 100W two-way fast charging, reaching 100% in 1.2 hours, and includes a 26800mAh power bank with USB-C and 400-lumen light. It operates in temperatures from -4°F to 140°F, offering a powerful, compact emergency solution.
Good luck and safe travels.

Backstory on why I own a jump box.
I joined the Forum bought my hybrid Maverick. First I started reading about the battery issues with the EcoBoost. Then I started reading about the battery issues with the hybrid. Because of the places I travel in Nevada, Utah, Idaho. I often times do not have cell phone service. Comes down to

Don't forget if you buy one. A regular USB charger will not charge it to 100%. You have to buy an optional higher amperage charger. I think the one I bought was like $30 I'll see if I can post a picture of it.

Agreed, especially since most of them are made in China.

I thought Schumacher was a good brand with offices in Mount prospect Illinois.
10 years ago I bought my first jump pack it was called Red fuel made by Schumacher. I had it stored in the back of my Yaris on top of the spare tire underneath the rear floor panel. When I went to check on the charge. The case was split. I notified Schumacher they told me to send it back and they sent me a new one. About a year and a half later the new one split.
I had folks tell me, 'You kept it in a hot car.' Doesn't do you any good when you're car craps out on the road and the jump box sitting at home in an air conditioned house.

A year ago last Christmas my nephew gave me this Stanley combination jumper and tire inflator. I like the tire inflator. I can set the pressure and it automatically turns off.
I jump started my neighbors 21-year-old Lexus V8.

I like the jf.egwo

3000amp combination jump starter and air compressor. Works well and holds a charge. Can't find it on Amazon anymore?

Plug it in to USB in rear of console which is on the ignition switch. The Noco has internal bms if you want to trust it. Or just use the rear USB charge port for a drive or two once a month.

Dave...they make a bigger Noco for twin battery diesel trucks. GB70 I believe. I've got the big one in my F250 and the little 40 in my Mav.

Thank you I will check it

Yeah they work amazingly well, and a lot safer than two drunk guys with jumper cables too. Not that I would know.

“Hold my beer”,
Hey Bob check this cool spark out when I tap the red and black together.
:’P
Never been let down by my cables in the very few times I’ve needed them and they are nicely rolled up inside my ditty bag under the back seat.
Seems when I need them it’s some other blokes car that’s dead.
I tend to maintain my battery and can see a problem before it’s a dead battery.

Thank you I will check it

I have a gb50 that I started my neighbors diesel with. I don't remember if it was her two battery for sure, I think so. In any case the larger battery in the gb70 would be a better bet.
ETA: IF you have deep pockets check out the GB500+ (on sale for $1,999.95) start up to 45 liter diesel!
