Portable Battery Jumper

[Klew]

Hey you guys,

I have been looking for a portable battery jump pack but not finding what I'm looking for without it costing a fortune. Has anyone out there found one that will jump my 7.3 Powerstroke (E-350 Diesel van). Thank you for everyone's help.

Well, they all just have a sm battery inside. The biggest ones I'm aware of have maybe a 27 Amp/Hr in them. NONE of them are going to run Glow Plugs for 30seconds and then have the reserve to crank a diesel over (replacing your Twin 850 Amp/Hr batteries).

So I guess it really depends on what you need it to do. If your batteries are starting to crank-down as you start and you need a little help maybe a big one will get you through... BUT, if you have two dead batteries you're not ever going to get one to "fill in" for them

When my alternator gave out I had a company come to jump it, after we couldn't get it to crank with the Napa truck. They brought a Sears Diehard jump box. ($100 or so new, the biggest one they sell) as soon as I turned the key he could watch the power gauge on it drop. It did turn over a few times... just real slow. In 5 seconds of slow cracking, his box was dead. He said he was jumping cars with it all day and my truck had a short, his box wasn't the problem. He left mad that my truck ended his day early. I even called to warn them what they were getting into. They claimed to jump a medium duty truck with it before.

If your batteries are dead, it's not going to work. Roadside assistance from my insurance company is like $5/ month. Mine has paid for itself in one use.

no such thing. i have one that i use in my fish tank. it will work on a 4 banger or even a v6 or a small 8. but after the glowplugs and then the starter, its not going to happen.

if its warm you can disconne/t the gpr and a booster may start the trcuk, but it will not run the gp's and turn the starter
