Using Jump Starter To Open Frunk
 

Can you use a jump starter to plug into the 12v receptacle to provide current to open the frunk when you have a dead battery?

I'm reading the instructions for the jump starter and it seems to say that plugging in the male-male cable into the 12v receptacle is to charge the jump starter, not charge the car battery.

Anyone every use this method?

Yes
 

when my battery died I connected the negative to the door latch and used a Phillips screwdriver for the positive and it only took a second for all lights to come on....push the button and open frunk

What do you mean you "used a Phillips for the positive"? What exactly did you do?

Simple, connected the negative clip to door pillar catch....positive on a Phillips screwdriver ...touch tip of Phillips to center of lighter receptacle and you can open frunk

Just make sure you don't touch the sides of the lighter receptacle. Wouldn't the safer choice be to pull the little red tab in the fuse panel and connect the positive to it? That's what it was designed for.

Mine did not work, so I used the lighter outlet. A simple length of electrical tape will greatly reduce the danger of a short.

I wonder why it didn't work. I'm glad you had a back-up solution, though.

I only connected long enough to open frunk, I would not try to charge or jump from this method....in fact after I did this I made up a cable just for this emergency using an old cigarette lighter plug and cord. I used red heat shrink on the positive wire and made it 6 inches longer to avoid a short if used again.

OK, I can picture that now. And the electric tape is a smart move to avoid a short.

On the Jump Starter, do you have it in jump start mode or something else? Is there any concern about overloading the 12v receptacle circuit and blowing its fuse?

I actually used a small 15 amp battery charger, it is only going to draw a small ammount of current for a short time anyway
