You know what that tells me…jump packs are a scam. They don’t need to be that friggin big.

40V into your 12V system - car will start but could fry you electronics on newer cars Maybe stick a high power resistor between the 40V and the 12 V batteries 🪫 🔋

As an electrician, we've had alot of vans in the field and always have 18V milwaukee batteries on them. It definitely works. The 18V batteries typically sit at 21V with no load, when the vans started it'll drop significantly to 12V to 14V. With that said, we've got the 12.0s that are 72WH. From fully charged, it'll go to a single flashing bar immediately after you start it. It may recover a few bars after it sets for a moment, but this is not something you should do on a regular basis. Jump packs are so big because they need a bank of batteries to handle the high discharge that a car requires to start. Doing this on a regular basis will fry your tool battery, trust me I've got a tote of old batteries at the shop that is almost full, a good half are jumping batteries. It's definitely good in a pinch, but it's not something you can do alot.

Myself and a couple of buddies were out ice fishing a couple of years ago and one of my buddies locked his keys in his truck with the key in the ignition, on acc….. so the battery was dead, but he had the fob in his pocket. We used a drill battery off my auger and some wire to back feed power through the trailer plug. We got enough through to unlock the truck then used the battery to jump it. We did feel pretty smart😂

Take it off before you blow your system! The reason this works is that the dead battery acts like a resistor in the circuit. That drops the voltage, and since it's current limited drops the total power. So you usually need to wait a tick. BUT if you pop in an over voltage you can overcome the resistor that is thr battery and turn the car on. BUT there is a problem. You are NOT using a voltage limited power supply. If you had say a 40 volt battery and a proper electronically controlled power supply you could up the voltage enough to bring the whole circuit to 12 volts even after the dead battery resistor. And bamn, just as good. The problem is that without that electronically controlled power supply you ARE causing an over voltage in the whole system and if you leave it too long you will release the purple smoke from the expensive car bits.

My jump pack has a tire inflator, usb connections for charging, and an attached flashlight that swivels. I wasted money 😒

Been doing this for 10 years. FYI it sometimes destroys batteries.

I wouldn't try 40v on anything I plan on driving every day! 12v yea, 18v maybe

Or, 8K Amps for $90, that jumps a diesel truck and comes with a nice carrying case? I'll spend the 90, but good to know
