Can you guess what's in the box?

A look inside the little inline box on a generic vehicle jump-starter lead.

Can you guess what's inside before you view the video?

I am feeling cheated, I borrowed a jump start pack recently to have a poke around and it has boring typical wires. I am very curious as to how these packs over-current protect as it blows my mind when I see them turning over an engine. I remember the lead-acid jump packs that were popular a few years ago. Every one I had died because, never found out why. Great video Clive!

That sounds quite neat. especially being LiFePO4 cells. Does it have over-discharge cut-off?

I picked up the Lidl's version of the jump start pack as I noticed something rather interesting about theirs - It uses LiFePO4 cells. Its capacity is rated at 8000mAh (3.2v) or 2000mAh 12V, 200A peak output. For €40 (clearance), it was cheaper than any equivalent 12V LiFePO4 battery as I wanted something lighter than the 12v 7Ah lead acid battery I typically use to power a portable water pump. It has an EC5 12V connector like others, so had a look at eBay to see what there is to fit it. Besides replacement battery clips, I found other adapters such as an EC5 to lighter socket and to bare wires for DIY, so will probably go for the bare wires along with an inline fuse. It's great that it can be recharged by USB.

I wasn’t expecting that!!

Yeah, I was thinking the same thing

Paul Smith

Yeah.. guessed right..surprised it was as good as it was

Guessing large diode for reversed connections, however I will be surprised to see that there is noting in it. Maybe fusible link

Vaughn B.

My eyes could be deceiving me but those diodes look to have a different number on each one.

I know this, I've read _Dune_! "Pain."

before starting, my guesses are "ferrite choke" or "bugger all"

Some kind of auto reset hopefully!

Guessing simply a fuse
