Does anyone know the number of amps this projector draws? I am assessing if I can power the projector from my RV battery when no AC is available.

Even the company website doesn't list the amps used. A standard ac/dc adapter should work fine to charge the battery. You can also run it on the charging cord, but it will not charge the battery while doing so

The supply brick says 0.35 max (amps, presumably). It only puts out 3 A at 5 V, so the actual draw is probably closer to 0.2 A.

I tried to hook up with a USB 2 amp but finally just got a small invertor and plugged into my cigarette lighter plug.

.25A with the projector turned on; .08A if it's just charging. Measured it with my Kill-A-Watt.

Every type of projector come with instructions on how much hours it will last. I have used my nightly for about 2-3hrs for a given period of three months and have not had a single problem even unto this day. But I do suggest also that when using place it on a surge protector. I don't know how current fluctuate by you but it is a safe bet, than any rise or fall in electricity you can protect your investment. Hope this helps

Yes you can run the projector without the battery installed, my battery stopped taking a charge after 6 months.

Well,I guess you can use it in the desert,if you have electricity. It does have very sturdy ground stakes. It is very big.Its great.Worth the buy.If you buy a projector for it,remember to get external speaker or speakers. its not very loud without it.I would set it up befor you are actually going to set it up for people to watch a movie or something. There is adjusting you have to do to the projector to get a better picture.

Yes, it uses AC power. Mine plugs into a power strip which goes into the wall. I've never used a projector so I can't comment on that, but we get more than enough volume in our living room. If you like huge bass and massive volume though, you might want to spend a little more and buy a more powerful sound bar. This bar would be what I call an entry level product that improves TV sound substantially for casual listeners, but perhaps not enough for power listeners.

It would depend on the projector and it's power consumption. However, if it's an outdoor projector system, I really doubt it.

thank you all for your response. I now understand what I need, at least 8 amps power supply ...enjoy your weekend!!!! :_)

Sorry, I thought this was a different model. I have a different one (HD2VGAE2) which does not require outside power. sorry for the mix up. I have used the one I have to run a monitor and to connect to projectors and it works great but it will only do HDMI to VGA.

I've had it draw up to 2 Amps on a bench supply, and it'll burn through regular batteries very quickly so I imagine it'll pull more than just 2 amps if it's unchecked

Currently have it running through the USB port on projector. It does come with a plug adapter if USB is not an option.

Yes. I do this all the time. Keep in mind that as long as the projector is on it won't be charging the battery but it won't drain it either.

The battery in packs like this have a rating like "18 amp-hour" hinting it can supply 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, etc. Running the inverter will use a bit of energy itself, otherwise it just transforms the power to 120V where something needing 1 amp at 120V needs 10 amps at 12V (since both of those =120watts). I don't know exactly what your blue ray player or such uses, so the only way to know for sure is to measure them in use with something like the "kill-a-watt" meter. I doubt they need much energy, so if it's under 1 amp at 120V the battery should last at least 2 hours, but that's a guess.

joseph I did not check with my amp meter, however is your application special need like low draw will ??? otherwise for RVporch and interior use the draw is very low and I really like for RV use hope it helps gene

I believe it draws around 6 amps/hr. If you know (or can calculate) the total amps in your battery, you can divide it out to get approximate hours of use. In my camper using a deep cycle battery I can easily use on medium for two nights without a problem.

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).

According to the label on the wall wart that comes with the projector, the INput is 200mA @ 120V which calculates to 24 watts input maximum. The OUTput is listed as 6 vdc at 1.0 amp which calculates to 6 watts OUTput. Not much. I'm not sure what you want with a timer for . . . the unit has a timer internal set to 4 hours or so. It automatically shuts itself off. That information is available in the description on Amazon. I've had mine awhile now and still enjoy it.

Almost nothing. This isn't an active device. It just a reflective screen meant to be projected onto by an actual projector. The only power used is for the little motor that raise or lowers the screen.
