if I do not want to use the energy of the car, i can used a battery 9 V??

The lights use very little power at all. In fact I would say carrying the weight of the 9 volt would use more than running the lights off car power.

Not quite sure about that?! I run these on my scx10 jeep with a castle creations BEC and have the voltage set at 6.3v and haven't had an issue. .and they are quite bright...i guess you could if you wanted to tear them apart and add some 300ohm resistors in line with the leds then run the 9 battery

Its only a 5 Watt panel so no. Running something from a solar panel, without a DC battery, isnt practical anyway if you need any sort of a constant voltage.

A car battery is 12v. It's saying you need a car with a battery. Pretty simple

Yes, but because of the voltage requirements make sure you use the device while the vehicle is running or you risk quickly depleting the car's battery.

If you have an AC outlet in your vehicle you should be able to do it. I would recommend having the vehicle running, so as not to drain your battery. It only operates on AC.

No, Anything over a 5w panel and you want to run it through a charge controller first. You risk overcharging a battery (which will eventually kill it) if you don't, even 5w is pushing it unless its a 70ah+ size battery and it has a constant small draw from it (Like in a car where electronics are being run even when the car is off)

I use a 9v battery. You will need to adjust the battery connectors a little, as it tends to be a little wide.

You can leave it plugged in but be aware that due to the budget construction it has minimal protective circuitry and could have a short lifespan running constantly, and that many vehicles have powered OBD ports when not running so it will gradually drain your battery. Estimates for current vary but are generally between 50mA and 100mA which isn't a lot but is enough I wouldn't leave it plugged in for more than a few days without running the vehicle to keep the battery charge level acceptable.

Oh, whoops. I used mine while the engine was running with no problems. My 12-volt ports aren't powered unless my car is at least in accessory mode.If you're really afraid of your battery dying, you're probably ok using it with your car on. Just wait until your car is started before plugging it in (to prevent a surge) and make sure your parking brake is engaged.

Automotive Tools Distributor. It's their brand and no you cannot use electricity to power it. You need an air tank.

I'm 99% sure that you can just pull the 9V battery out and use it via a normal key if you didn't want to use the keypad.

Yes you can, but in the long run it's not good for the battery. It also has the car charger.

Don't remember. Earth to the body Of the car the unit than run power from battery to unit you will be fine ,

It works perfect when you practice without power, I love this stuff... But I want to take care of the 9V battery.

Don't use a car battery, get an AGM battery. They are more expensive but worth it.

Yes you can . I use it with a generator to keep the agm battery charged in my race car. Thank you

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.
