Wait....did you say you jumped a van with your drill battery?
I'll have to remember that one.

If you put a volt meter on it I bet you see more like 16-18 volts

I've done the same with a Milwaukee 18v drill battery and two short
wires. Works surprisingly well. Saved myself calling for a jump
several times when I left a van door open too long at a tower site.

just a lithium ion polymer battery, most don't have any protection
other than a fuse on the output, maybe the expensive ones have
some sort of reverse polarity shut off..

I’m not going to open it up, but my guess is it’s actually a
12V lithium battery stack with very high current capability.
There’s definitely some smart circuitry in there, but to
prevent connecting it wrong and to only apply voltage once
it’s hooked up to a battery.
Keep in mind these things are only for short bursts of current
to start the engine. I think the manual talks about letting
it rest for 15 minutes after 5 tries, and only getting 20-40
tries on a charge.
It does have a USB port for charging your cellphone, and a
built-in flashlight.
There are 2 ways to charge it, USB or the 12V power port (we
used to call it a cigarette lighter) on a vehicle. USB method
takes a long time.

You have to wonder how they do it. High voltage battery pack
with a huge DC-DC convertor or what? Does not seem possible
but my son has one and we use it on construction equipment all
the time.

I was skeptical of a lithium battery based device that fits in
a glove compartment being able to jump start a big V8, but I
picked up a NOCO GB70 at Autozone for my son and it worked as
advertised.
At $200 it’s not cheap, actually more than a spare battery and
a set of jumper cables. But this gizmo is a lot safer and more
compact. No sparks to set off a hydrogen explosion, and no
worries about reverse polarity or shorting the cables together.
He has an old Grand Prix GXP which is hard to turn over and
also seems to eat batteries every 2-3 years. Oh, and it’s
wicked cold out.
