NOCO Boost Plus GB40

So I got one of these for my daughter.

While she is here I thought we would run-through-it so it wouldn't be the
first time if she ever needed to use it.

Can we 'do-this' with a fully charged car-battery?
That is hook it up, turn it on, crank her car even tho her battery is still good?
Am I going to start a nuclear-fusion-reaction by doing that?

 

Not sure about "feedback", but attaching is simple ... red to red, then black to black, then press power. Wait 10-30 seconds for some power to start flowing. Practice on a couple of pieces of wood that do not conduct, or attach to rubber parts near the battery.

You can show the other uses ... attaching cell phone to USB-A plug and press power.

 

Yes, it won’t hurt anything

 

Right, I'm yapping about hooking it up as if jumping her car and actually turning the engine over
while the thing is turned on - will doing this with a 'good-battery' mess anything up.

 

Cannot state for sure ... never done it. I like to not risk such things but others may say "no risk".

But there is little difference between pretending to attach red/red and black/black then turn it on and wait ... to actually doing it. But you do as you wish ... probably nothing will blow up.
