Li Jump Starter

[Ronin]

Hi all,

A recent topic on recovery gear has me thinking about replacing my heavy and bulky JNC jump starter with a Lithium Ion booster. The JNC is rated at 425 cranking amps and it's hard to compare with the Li specs. I have a Tundra 5.7L and can't decide between the 1500amp Noco GB50 or the 2000amp GB70. It's $150 vs $200 - I understand the whole rationale about it's only $50 bucks more but I also don't like throwing away my money either. I'd appreciate thoughts from folks who actually have real life experience with the Noco's or similarly sized units.

Thanks!!

BTW- although I'm always happy to help others in need, my main concern is which product is appropriate for my
rig.

I Looked at both those units about 2 years ago and decided on the GB70. I wanted a unit that had enough power to start my 6.2 gasser when the battery was dead, not just low. Another plus is we can use it to charge cell phones several times if needed and still have enough charge left to jump the truck. It is quite a bit larger than the GB50 though, so that is something to consider. I've used the GB70 1/2 dozen times now on autos, my boat and lawn tractor with no issues, plenty of juice. Holds a charge very long time.

I bought my EcoJump model GDI-EXJMP1500/1520 at Costco.
Says it has 500A Peak Current and 200A Start Current.
It's the size of a thin brick.
It has worked great the several times I used it ,on other vehicles.
Also was great when I forgot to charge my cell.

This size is good for my needs and stores away in a small place.
I move it from vehicle to vehicle as needed.

I have become addicted to Project Farm YouTube videos.
Based on his testing I bought the Audew jump pack for all our family members and they have been used several times.
Highly recommend!

I bought an AntiGravity unit more than a couple of years ago. A little on the pricey side but I like that it holds a good charge for a long time without worry.

You want a jump pack that can still start the engine when IT is at a lower state of charge. Unless you go all foolish I don't think that you can buy too much Li-On capacity in a jump starter.

I don't want mine to be on a constant charge, but I do want to keep them topped off. To that end I've found a relay in the "sugar cube" form-factor that can be used to time how long the charge cycle lasts each time the ignition is turned on. The jumper starter and a rechargeable flashlight will both be out on that circuit as the initial test of the idea.

How many amps is your AntiGravity rated for?

Ronin: I have an older (10 years?) XP-1, rated 200 amps starting, 400 amps peak. Currently priced at $150, I think I paid just north of $100 at an offroad show. The XP-10, rated 300/600 amps, is close to $200 a pop, $220 for the HD unit. I bought some Costco units for the wife and kids to stow in their vehicles and they seem to work fine, also. You’ll want as much power as you can get if trying to jump a diesel, although my cousin has jumped his Chevy inline six 3.0 diesel with a smaller unit like the ones from Costco.

Good to know your XP1 is still alive at 10yrs old and you have real life experience using them. This is all new to me and it's hard to believe these little 2 lb units can jump start a truck. Thanks !!
