Can you simply hook it up to an auto battery? Will 14.4v (auto) damage the unit?

Yes, you can. It only needs a 12 volt power source; which your car battery is.

You don't want to plug it into the cigarette outlet, it draws too much power for that and you'll blow fuses or fry the wiring. You'll want to hook it up directly to the battery.

You could use a Lith battery. When you get the unit test it immediately. The unit I received had a defective manual function.

Depends on where you are planning to wire it in. I would suggest you watch tutorials videos and buy a voltmeter. Everything else, you can do it!

Yes you can power the system by battery. Just be sure to use fresh batteries when installing them. The unit will have a visual and audible warning when the batteries are getting low to warn you to replace them.

You can just plug it in or do as I did. I bought a electric timer for $ 10 to plug the unit into. Works great.

I only use it in my home plugged into my house current so I don't know if it can operate on an auto battery. It does draw a considerable amount of current and sometimes causes my circuit breaker to go off when I try to run too things at the same time.I hope this helps you.

This unit comes with a DC 6V 500mA plug in. It also can be run using 4 - AA Batteries. I hope this helps.

Sorry Franz N. I'm not familiar with auto volts, why don't you ask the Briteleaf company or Amazon.

The output of the auto ranging power supply is 5 volts dc at 1.5A. If I really desired to run the picture frame from batteries, I would try it by hooking up 3 or 4 D cell batteries in series to a plug like the one that comes with the frame. The parts to do this should be available from Radio Shack. The skill to hook it up should be available at an above average Radio Shack, an old school TV repair shop, or an old school electrical engineer (possibly an independent cell phone repair store.)

Only do this with a DC-DC converter (12 to 5V) as the power cord that comes with this decreased the input voltage to this (via a voltage divider inside of the plug). It will run with 12V but this will decrease the life of the unit. A DC-DC converter can be purchased on Amazon for around $6.

I have never been successful using this unit to jump-start a completely dead battery. I needed it 3 times and ended up calling AAA each time. There is a circuit that looks for proper polarity before it allows current to flow. You can plug a device in the front port and you probably have 12 volts there. I don't see any point in replacing the battery as the polarity circuit makes this product useless. Worst automotive purchase I ever made.

Yes. It will work from 12v or 24v. Use a momentary switch or a rocker switch with it so you can turn it on and off.. or just hardwired it in and it will be on the whole time.

No. Just hook it up directly to the 12volt battery posts. I have owned mine for some time now and it works very well to keep my RV auxilliary battery charged.

No, you can't use it because it can handle only small load like 10mA. Car batteries' load is in the range of 5-10A. You will burn this tester in no time.

Depends how you wired the unit, I went directly to the battery and did not experience and ancillary side affects.

none. you have to connect the supplied plug to the 12 volts battery of your car.
