I'm surprised this is the first comment. I have one that looks identical but with a different name. Your video was excellent, it showed the capacitor bank was able to charge even with an almost dead battery. With a battery that's too flat to start the car but not as flat as yours it only takes a few minutes. Good to see it will get you going in such a bad situation.
Just a word of caution though, since it uses the low remaining power to charge itself, it does drain your battery further. Once started, you can drive no problem, because the alternator is taking over, but keep in mind your battery is still low. You need to let the car run or drive it for at least an hour for the alternator to charge the battery enough if you what the car to start the next time. But it will get you out of trouble when your car is won't start out of the blue and there is nobody around to help you. I keep the batteryless jump starter in my car's trunk and it works even during freezing cold winter days. You definitely can't do that with battery powered jump starters. I would suggest using someone else's car or a wall outlet to charge it when possible, and if you've got a car battery charger at home, put it on charge once back home to ensure it get fully charged. I didn't do it and at one point point I needed to use the jump starter a bit too often, the more I jump started the car, the less the battery would keep a charge. Fortunately the battery was just a year old and managed to get it replaced under warranty. Note that this applies to jump starting in general, but since this one will drain the battery further to work, it's even more important
@@AlecKristi its always better to contect somthing like that as close as possible to source.. Maybe it will make charging time shorter next time if you try it from trunk.
@@Xv1p3rCr0 charging time will not change, as charging draws very low current. however, when you try to start - current will be lost on the way to the starter. so, it is much better to connect as close to the starter and as far from the battery as possible.
@@AlecKristi while that is true in starting,(that position) doesnt apply to charging for obvious reasons, resistance. Voltage and current is always used not only current.
@@Xv1p3rCr0 when charging, the unit uses a boost circuit that only draws a couple of amps at most. the voltage drop over the massive cable coming from the battery will be close to "nothing volts" ). so the charging time will not change whether you put it directly on the battery or under the hood.
It is lead acid. But it's not being charged by this box, this box is sucking out the rest of the juice left in it to charge itself, and then provides power to jump the car.

Ist it schumacher dsr 108 or 109?
Ist is

This device is amazing :)
Where did you attached the red cable, its that the + battery terminal? I don't see any battery car
BMWs usually have the battery in the trunk, this is the battery jump terminal which is under the hood.

What type of battery your car uses? Don't say its not lead acid, because lead acids can't be charged this rapidly

@@AlecKristi wow, get it now. Thanks
But it's not good for the battery too. You can charge it from some other battery too.
The connection is wrong…both jump starter cables should be connected directly to battery terminals.
incorrect. wires should always be connected to the vehicle jump points, not battery terminals.
Doesnt really matter, all goes to the same place'es anyways, lol.
