The power input is listed as 12V...Does it have an AC power supply/transformer? How does it get to 5amps from a car battery hook up?

Car batteries can supply up to 700+ cranking amps, but that is not the point. This device is going to use 5amps at 12 Volts. So you can hook it up via the cig lighter or wire direct. But I agree, this should have came with some documentation. It came with no specs or directions.

does not come with a power supply, I wish it did, still a great buy. best way is to run straight to car battery. Makes it a clear base when it pulls amps...

Yes, gets powered by the USB port. Yes and I have used a 12 Volt car adapter with multiple 5V outputs or any other 5 Volt usb adapter does the trick. No need to use the provided charger

yes it does! Input: AC 100V-240V 50/60HZ MAX 150MA DC 12-24V (CAR CHARGER) OUTPUT DC8.4V.....600mA Hope this helps!

Rarely are these things under represented as to features, but this one is. I just bought it, and the specs say it runs on DC from the car, but they don't say it includes an AC adapter, which it does. You do not need to purchase that.

There is a 3V DC 500mAmp power port, but the transformer does not come with it. I'm using it with rechargeable batteries--no problems so far.

Yes, it is 12V AC. However you need a min load to be hooked up to get an output (can't measure with a multimeter)

AC input 120-240v at 50//60htz DC input 12v- 24v (car charger) Output DC 4.2v Thats off the back of the charging unit.

That makes absolutely no sense. If you have a 12 volt winch hooked up to a car battery, why do you need a power supply to power the winch? You do realize that this converts 110 household current down to 13.8 volts, right?

This is not a battery, so does need a 12v power source to convert DC power to AC. You could use a 12v lead acid cell to make it portable I guess but then it would be quite heavy and a messy solution. Why not just get a jump starter emergency power source which is all in one neat package. With battery and inverter to AC all in one neat package. How long it lasts will depend on what you are plugging into it. No hair dryers LOL.

Since it uses 8 1.5v batteries you could use a 220v ac to 12v dc adapter (or a car lighter power tap) but you would need to wire it in yourself at your own risk. I have used it plugged (fused adapter) into a car lighter w/no problems.

it does not... but you can buy this from Amazon and you will be able to plug ANY AC Cord into it off your 12VDC Power supply-TsirTech® 175 Watt Portable Micro Power Inverter With USB Port --- 12v AC to 110v DC Car Plug Outlet Converter For Your iPod, iPad, iPhone, Android, Tablets, DVD Players, Laptops, Netbooks, And cellphones

It is rated at DC 12V. Not sure what "AC" power connection you're referring to. So, if you want to connect the wires to a cigarette lighter type plug, it will work fine.

This power supply will provide 12volts DC at 4 amps, that is 48 watts. I don't know what is required to run your car stereo with cd changer. What are its specs?

Yes, it takes between 100 and 240 Volts AC input at 50/60Hz @ 0.6A. The output is 12V @ 2.0A. Plus it comes with three different power adapter plugs. The regular one for North America of course, along with one for the UK and one for the EU. They just snap on the power plug. A nice universal power adapter. Hope this info helps.

It has both power supplies ...... Comes with power supply and takes AA batteries... It also comes with a USB power connector which will tie into a Computer or car cell phone charger Love it!

It is 120 volts AC ONLY! Standard wall plug, two prong. The 12 volt DC cig. lighter adapter is so that you can charge your car battery from inside the vehicle.

Looks like it plugs into a cigarette lighter in your car. I don't see any AC outlet nor do any of the reviewers mention 120V AC ouput. Hope this helps.
