Nebula Prizm II Full HD 1080p LED Projector

We got this projector for watching movies outside while car camping. Overall it's ok, but there are a few things you should know about as you make your buying decision. 1) there is only a power button on the projector. All the controls for input, screen adjustment (e.g. keystone) and controlling playback are on the remote, so you must not lose or damage the relatively small and thin remote. It uses 2 AAA batteries but there's no protected pocket in the case that keeps the buttons from accidentally being pressed during travel/storage, potentially resulting in a drained batter,y so you might want to pull out one of the batteries from the remote when you travel and leave it in the bag, not in the remote. A physical off switch for the remote would be a better design and avoid ending up somewhere with dead batteries and no way to control the projector. 2) the light level is ok, but not great. We had a difficult time seeing the projection at any time, other than complete dark/night. We were rear-projecting onto plastic film, which lost even more of the brightness, but holding up some paper in front of the projector still was difficult to see. We tried to use it during dusk and had to wait until it was dark until you could see the projected picture. 3) the sound is not very loud. We had the source turned all the way up (Samsung phone playing via USB-C to HDMI dongle) and also had the projector at max volume and it was just barely loud enough. I think you really want to have something with a separate amplifier if you're going to use this outdoors. The projector has a headphone jack but not bluetooth, so you may need to pair with the phone instead, but that could lead to audio sync problems, I don't have any way to measure the image processing lag of the projector, so it may be a minor or non- issue. 4) there is no picture size adjustment. The only way to control picture size is to move the projector further away from the screen. This sort of worked for us, but to get a larger picture meant moving the projector further away and we ended up with some objects getting in the way. It would have been nicer to have the projector closer and then manually adjust the image size from the projector. 5) the lens cap is very loose fitting rubber and is constantly falling off. It really needs to be tighter to protect the lens when moving it around or in/out of the bag. It falls off every time I move the projector. 6) the power brick is pretty large and barely fits inside the soft case. I was expecting the power supply to be built into the projector, but this projector has a separate power brick that uses a smaller barrel style connector to power the projector. ok, so that sounds like a lot of negatives, and maybe I'm using it in an unusual way, as a portable projector for mostly outdoor use. On the plus side, it's pretty small and takes and projects 1080p and is pretty easy to setup as long as you have the remote. the large rubber ring (square) on the bottom helps hold the projector in place and the front single leg pops-out quickly to set the right projection angle (there is no auto-keystone adjustment based on angle detection, so you will need that remote!). In a dark environment, it's decently bright so that you could watch a movie and if the area is quiet, you can definitely use the internal speaker. It's nice that it comes with a soft travel case and HDMI cable and the unit seems pretty well built and because it uses LEDs instead of a bulb, the life of the projector should be really long (think TV ownership timeframe... 10s of thousands of hours, not hundreds of hours) and doesn't get too hot. This is very important having had a portable bulb based projector in the past... bulbs require a long cool-down period, so you can't turn it off and fairly quickly put it all away. In fact, with a bulb projector, you really can't move the projector when the bulb is on otherwise you may damage the bulb filament... with the Anker Prism and it's LEDs, that's not an issue. I'm sure that lasers will be the future for the light source, but are too expensive now, so LEDs are a better option than bulbs. Overall, if the your use case fits with the above limitations, it's a decent projector. I'm not sure I'm going to keep it, but having the ability to put a movie up on a wall or screen quickly has it's advantages. Sadly, using it around dusk at the campgound was not a good fit.
