You may be able to use this as a power source and use a device like the "Wagan el9796 jumper" to move power into the dead car (or power AC chargers off the inverter going to the lighter).

There's several brands of devices like that Wagan one which are labeled for "jumping" cars and will actually "pump" power into the dead car thru the lighter plug (where other cables like the Clore ESA1 cable that are just wires with lighter plugs won't move much power to the car). The advantage of those lighter plug "jumpers" is that you don't need to open the hood and directly connect up cables (with some being afraid of connecting the cables wrong or standing in the rain). Yet there's several disadvantages of them including it takes 10-20 minutes to slowly "pump" the power into the dead car (it's not just plugging it in and instantly starting), the car battery must be a "good" one that accepts the power and can start the car (if the car battery is "bad" the slow charge won't start you), and you will burn some power doing the "pumping" of power (or running the AC inverter for AC chargers). Also some may forget to have the key in the "dead" car in "accessories" so power can go thru the lighter plug, but you don't want it in "run" until trying to start so the engine to minimize power used while charging. Those issues have given most of those devices a low rating, yet it makes sense to me that it takes the time to send low power thru lighter circuits, etc. So don't be surprised about those restrictions. Feel free to add comments if you have other questions about the device you have or such. see less You may be able to use this as a power source and use a device like the "Wagan el9796 jumper" to move power into the dead car (or power AC chargers off the inverter going to the lighter).

No, directly to the battery. It’s not possible to start a car through the cigarette lighter.
