Info Bleg:


Has anyone owned or used one of THESE?




Comments?

The reviews are good, but I find it hard to believe that:


A: you can get 400 amps through those teeny tiny little battery clamps and cables (much less the connector)

2: you can even GET 400 amps out of a battery pack like that, even dead shorted.

III. you can get 10-20 starts out of such a small battery.

I mean, a huge capacity battery pack like that would be great for traveling to charge the assorted devices we use.  Lots of recharges. 12 AH battery will power a cell fone  for for a long time and all.....

And having a jump starter is never a bad thing.
But the jump starter part seems too good to be true. 400A...even once?

Yet, as I said, the reviews are really really good. Not all of the 375 5-star commenters can be lying or paid shills.....

Almost seems too good to be true...

I bought a similar but not that *exact* unit from my trusty Snap On dealer. I have used it several times. I am happy with it. I do find that the response to connecting up is not instant, and you have to wait a few seconds for it to crank the engine. So far , so good.

They work when the engine you are trying to start, starts quickly. There is not that much juice to crank and crank. The cables wire gauge and clamps are not for sustained cranking.
If you are going to use this for occasional engine starting or a power supply for a phone or computer it is fine.
If you are going to use it to start recalcitrant engines you would be better off with a very good set of jumper cables.
