Can you run without the battery? Meaning, just with the plug into the wall? I saw one post where a guy said the battery wouldn't hold power for "a whole movie" and that you can't play through the projector while charging the battery. Another guy uses...

You can run the projector straight from wall power. The battery will charge when the projector is plugged into the wall and turned off. If the projector is turned on, the charging process is stopped and the projector runs entirely from the external power source. If the AC Adapter is then unplugged, the projector will switch to battery power. Optoma has sent me a replacement battery, and the life is now much closer to the advertised value(3 television episodes).

Yes, you can use without the battery. With the battery the recording time is not long , less than two hours .This product is very good , I'm very happy , buy it for very little $ 140 d and quality sound recording and video is spectacular .

I run it on the battery. The instructions that came with it said it is better to run off battery rather than run on the power adapter, although that does work too. Just used it in a small gig today and it worked great on the battery.

The battery will only last an hour or 2 when not plugged in. They state that in the owners manual and I have tested it myself. I will tell you though the monitor is amazing and I love it!! It is super easy to set up, has good night vision and great sound. I am very happy with it!

Hello. The battery cannot be bought. It is cased inside the unit. I found that the battery last quite a while. Can't tell you exactly because I charge it often. The battery is suppose to recharge itself when the dvd player is in use. I hope my experience helps you.

It can run attached to a power source but only with battery in. Thus you slowly destroy the battery's capacity to hold a charge. If you can remember to turn it off when not using, then battery will last. Don't buy it if you have a choice. I have three so far -- they only keep working about 6 months.

It is not recommended to run it while plugged in. Like most rechargeable products, it it intended to run from only the battery. Properly charge up the battery before use, let it discharge and then recharge.

Unfortunately it can't be run without the plug in wall adapter. I was hoping it could run off of USB power cord that is supplied with it but it turns out the USB attachment is only meant to power the LED's.

The unit can be plugged directly into the wall and run without batteries. That was a BIG deal for me and I could not find the answer to that myself. So glad to tell you... YES! And I highly recommend this unit. Also, you can charge both batteries at the same time.

I actually have not used the speaker with just the batteries on. I have been using it plugged in all the time.I am now curious to see if that happens if I tried it with just the batteries. It could a power saving mode.

I can only answer for the one that I own. I can plug it in and it runs just fine, especially when battery is low. If your battery is completely dead, with no chance of ever charging again, it probably has a short and it, theoretically, will NOT work when plugged in either due to the shorted battery. I hope somewhere in what I said you find the answer that you were looking for.

The battery life is about 2 and a half hours. It is sold with a wall charger. If you are watching something and the battery is about to die, it will flash a warning box so that you can plug in the wall charger and not interrupt your movie.

I was able to play music on a USB flash drive when running from the battery. If I plugged it in, the music would not play. However, I can play music on a MicroSD card when the speaker is plugged in or running on the battery. We use it to play calming music for our dogs when we are out of town, so being able to have the speaker play while plugged in was important.I hope that answers your question.

It has its own proprietary battery pack. You can buy extras on Amazon. I've used it to play movies onto the back seat of an airplane during flight, but one battery will get you through 3/4 of a movie. This works great! You do not need a computer to watch these movies, only a memory chip with the video on it, and an earphone. This is also great for hotel rooms at night projected onto you room wall to watch movies.

Neither it's a rechargeable battery. Always want it plugged in anyways. Lose lumens when u don't. Only lasts n hour anyways. Good if it gets pulled out that the projector won't shut off.

Hi, you can get a 3 hour movie in, but I think it's longer, just haven't watched beyond a major movie. Yes, while battery is charging you can use device.

Sorry for getting back to you very late...I plugged the AC adapter into the light and it did turn on, but this does not say that it is running off the adapter and not just the battery. I would suspect it was running off the adapter. I could experiment and drain the battery then do this again. I modified my light by replacing the internal 750mAh battery with two external 2000 mAh batteries. Each will keep the light going for about 1:45 mins for a total of about 4 hrs of use. That is good for my long ghost hunts.
