Does it have only battery and no AC power? Is it possible to use it for up to 12 hours? what should I do?

This works with optional battery (purchased separately) for 90 min. It can work up to 12 straight hours on AC power. Just plug it in & run for 12 hrs.

You will need to purchase the battery it does not come with one. It runs about 90 minutes on a full battery charge. It also runs on ac. AC charges the battery and the unit can run for hours. I have not tried it for 12 hours. Over-all a nice compact and bright unit.

It comes with an AC power adapter. You can purchase the battery separately. I would plan for no more than 1 hour on the battery.

Mine came with a battery pack already inside. Is that weird? I bought one because all the reviews said it didn't have one. Now I have two.

Not sure about specs. Mine came with a battery. I've had no problems with it. Not an exceptionally long battery life, but I would say about 4 hours. Hope this helps.

8 hours is the correct answer. I love mine. Use outdoors where there is no electricity.

Mine came with an Ac cord. The description says it is battery powered, mine does not have a battery, just a cord. Sorry I can not help

It is not a portable unit and does not use batteries. It must use the power chord to operate.

It comes with direct battery connectors so I use those in two hour incriminates without the car running for 14hrs and it never died in the ac outlet it will shut off after about an hour or so. Hope that helps

Unplug it, let it drain conpletely. The recharge it. Make sure it is charging and charge it no less than 6 hours. I found the battery lasts a long time but needs about 30% to power up. Charging for 3 hours wasn't wasn't enough. If it doesn't work ten sed it back . It needs a good but of power to start

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

This unit is designed to use the energy as it is made. However, you can connect 12v batteries to this and recharge those for later use. In most cases this is the best way to utilize power long term. If you need to run the electronics for 1 hour, but only plan to ride for 30 minutes, the battery is the best way to accomplish this.

It's only battery operated. Mine hasn't worked right from the beginning. I would not recommend this product. Hope this helps.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

This is not right.The battery for this computer most can used about 5 to 6 hours.Your battery is bad and need to be replaced or return the computer.

I hit the return too quickly. The unit is not portable as it is powered by the USB cable, not batteries. You can get a USB to AC power connector. The cable is not very long, but at least it that way it won't be tied to a computer.

If your battery is completely dead,charge it 6 hours.I found this to be adaquate.Problem is at full charge battery will only last 20-30 minutes.

1) no. 2) I have used a battery pack and it charges the camera's battery just fine 1-4 hours and during this downtime you cannot use the camera till it is finished charging. After my purchase I contacted the company and asked several questions also made a few recommendations as a customer that could make the camera more user friendly etc. No response! I am currently researching for another camera that will fit my needs and use this one as a backup or spare.

I apologize to you for answering too late. Its not battery operated just only AC. Best Regards.

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.
