I had hunted for ages trying to find a projector for my campervan that would work on a power supply like 12 volt cigarette lighter or 5 volt usb charger, and this one finally fits the bill.
Charging is easy and you can run movies on it whilst it is charging too.
My 5 volt 2 amp usb charger ports work fine with this device.
Whilst the projector is charging up using the mini usb port and lead provided, you can still run an hdmi lead to it from a portable dvd player, or stream movies to it via your iphone for services like Youtube.
The picture size will depend on how far away you set the projector from your screen, but the options are very good on how you stand or mount it. There is a tripod threaded screw port to connect this up to a tripod if you want, or you could mount it to the ceiling and set the picture to flip or reverse etc, depending on your setup.
You really do need a dark setting to get a bright picture though. Trying this in daylight or with curtains drawn in the daytime, will definitely be affected by ambient light coming into the van, so don't expect the 100 ANSI lumen LED buld to give you a brilliant picture in anything less than darkness.
The resolution is lowish at 854x480, but for a campervan setup where it is unlikely you will have the distance to get a picture above 50 inches, this is not a problem, because at that size it looks perfectly clear and bright.
If you are planning to go bigger, then expect a more pixellated effect and lower brightness. This thing is not a 240 volt 3000 ANSI lumen home projectore.
The projector is very compact in size. It really is like a can of soda pop, and the 360 degree built in 5 watt speaker is powerful enough to be heard clearly in a smallish setting. There isnt much dynamic range of course, or heavy bass response, but it certainly isn't a feeble tinny transistor radio sound.
i have tested this indoors using my wi-fi connection, and got Amazon Prime video working on it fine, as well as You tube videos. I also connected a portable dvd unit to it via HMDI and it worked fine.
Picture was tested from a distance of about a metre, giving about a 30 ins picture, to 3 metres giving about 100 ins picture, and in the dark room it looked fine at either size.
Amazing bit of kit, that can also double as a Bluetooth speaker as well.
I would recommend downloading the Nebula application to your iPhone to control the projector, as the remote can be a bit fiddly when trying to type in mouse mode for searching to movies etc. The phone app makes this a lot easier to achieve.
Did a lot of research before I bough this having sent back a higher spec model due to the battery being rubbish.
The res is only 480 but is superb for my van which is why I bought it and I have a 40” drop down screen.
Comes pre installed with YouTube and Netflix. Contact nebula support and they will help you unlock the Google game store so you can get itv player, iPlayer, sky news, YouTube (which allows you to sign in) , and all the other apps you want like Disney and freeview etc.
mine was set up and running with all the apps within 10mins of getting an email back from nebula support.
I do like the remote control on the phone app but it takes some getting used to, but easy enough to navigate and you don’t have to worry about forgetting the remote.
USB mini plug for charging on the go with powerbank is brilliant and idea for my usage.
Ceiling mounted in the van, and can be viewed in daylight although obviously not ideal.
I paid £265 for this item and it’s well worth it as far as I’m concerned. Don’t expect 4k quality but for basic usage it’s fab.
After having an issue with the manual focus and emailing the support team, it was changed for a new one and is everything that I wanted it to be.
I had an anxious wait due to the postal strikes but was well informed of the progress by customer service. I`ve been well impressed with the product and would look to upgrade in the future.
Wished I spent a bit more on the better quality Capsules. No auto keystone or focus let's the device down. Should be removed from market now and the technology has moved on. It's no longer fit for purpose so it's being returned.
