Neat Prius 12 volt jump start device

It's a neat device and PERFECT to Start Jump a stubborn Prius

 

Well maybe not.

I would really like to hear from someone who has actually used one to jump a dead battery.
While it might work for a hybrid that doesn't need THAT much to kick off the control systems, I'm betting it will be pretty much useless on a car with a conventional starter.

"this little device produces a 12 Volt output at a peak of 300 amps. "
Even if you actually believe that, which I don't, given its stated 6 amp hour capacity, it could supply 300 amps for about 1.1 seconds.....and then probably would melt into a heap.

And finally, this appears to be a brand new company.
I wish you luck.

 

While a 50C discharge rate is not good for the reliability of a LiPo battery, the actual calculation would be 1.1 minutes (not seconds), but then it would not quite pull that off due to heating issues. I will consider purchasing two of these to replace the 2 UPS batteries on my electric skateboard (a fun filled Engineering project by my freshman a couple of years ago).

But remember, WE ARE in a Prius related website and it's applications. For other heavy uses, I would't mind to exclude as a solution, even as an emergency.

 

Interesting product, should work great on the Prius. If I did not already have a portable jump start pack, I would buy one of these. Yeah, I know mine is big and bulky unlike the "JUMPR", but if I go out of town I simply put it in the back end along with all the other goodies.

I am sure someone will say but this is smaller, lighter and what have you. Yes, I agree with all of that. But for now I will stick with the product I have already spent my money on. Social Security and Disability does limit what I can do with my money.

Cool product though. I will bookmark it and maybe buy one later on to stick in the Prius. I like the fact it can be recharged off of the USB port also. Or at least I think it can be charged that way.

Thanks for the heads up!

This is a lot of BS to say it could jump start a Prius!

 

OK, let's see if I did the math wrong:
6 amp hours is 6 amps for one hour OR 1 amp for 6 hours; that part is easy.
300 divided by 6 is 50.
60 minutes divided by 50 is......well, damn, it appears that you are right.

You don't REALLY believe that little bitty thing can actually give up 300 amps for more than a flash though, do you......really ?? Even if the cells themselves would produce that much, the inter-cell connections would act very much like a fuse at that current load.

Most of the claims are pure marketing hype. I even wonder about the 6 amp hour rating.
I really doubt that it would produce 6 amps for more than a couple of minutes.
One amp for 6 hours; sure maybe.

And while it might appear to be enough to jump a 12 V on a hybrid, remember that the dead battery itself will sap off a good amount of current as it tries to re-charge.

I just ain't buying any of it.

 

This is easily believable especially for jumping a hybrid. This is high C Lithium Polymer battery. Tenergy makes 50C LiPo cells with burst of 70C. Reconfigure the cells and you can easily make a 12V battery pack with 600 to even 1000 amp continuous discharge rate. Recharging it would take a while though because high C charger is expensive.
Check out Batteries & Accessories>50~65C Discharge They have RC batteries with up to 130C burst. 2 of Turnigy nano-tech A-SPEC G2 5000mah 4S 65~130C Lipo Pack (US Warehouse) parallel will give you 650 amp continuous discharge and up to 1300 amp burst.

I jump started my dead Prius with an old DeWalt 12V NiCad battery with 14 AWG wire with 30 amp fuse. Surely a high C LiPo can easily handle the job.
