Is there any way to add additional battery power? I need more than 1 hour run time on battery.

No, it runs approximately 1 hour and a half. Then you have to plug it into power

Not that I know of. But with extra cost and eight, you can get a 12V or other DC (e.g., automobile) battery plus an inverter. If you do that, be sure the inverter can provide the load needed by the projector.

I'm sorry but I don't that battery compatibleas far for charging time, if you run it completely flat it's about 6 to 8 hrs

Have you tried to fully charge the poweradd before using it. I had the problem when I first bought mine. When fully charged I get about 4 to 6 hours of more battery life.

I have to agree with the other responses, very happy with the run time and when it needs a charge it is not more than an hour.

As an add on to my earlier comment- I would suggest getting an auxiliary battery. You can find them on Ebay or Amazon for about 20 dollars or less.

I haven't try yet but I think you can't, it is better not charge device wile the battery is charging, since the battery just need 7 hours to be fully charged.

I might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

Yes you can, but I would go to a higher "ah" battery for much better performance.

Sorry, cannot help, I have not reached the end of the run time yet. I use it about 15 min a night only, tho.

Run time 10-15 mins. at full power Charge time around 1hr. You can upgrade the battery

same battery with a bit more amp hours, should work quite well for you. I don't run out of power any more with these in my pocket.

I need it to run the computer while I use it. the internal battery goes dead quickly (less than 1 hr) while using unplugged. Need it to power computer in use for 3 hrs using multiple applications.

use owners manual, if not, google, settings to adjust screen time,,, all in all, it's there to prevent battery run-down.

I don't know I hadn't thought of trying that, it has a 2 hour battery according to the instructions. But you can run it on AC also. Sorry I wasn't much help.
