Philips PPX4835 Pocket Projector, 350 Lumens, LED, 720p, HDMI, USB, 120" Display

First, you need to reset your expectations - this Philips PicoPix projector won't give you a usable image at a 150" screen size. While you could see something at that width, projected in a completely dark room, the low resolution and low contrast will result in an unacceptable picture. I found that I got a usable image up to about half that size - still not bad for such a tiny box.These portable projectors are good for doing office presentations to a small audience, and maybe viewing videos with uncritical eyes. The Philips is small, lightweight and has a number of adjustments that can be useful. I was glad to see keystone correction, which is needed when the projector is not perpendicular to the screen. There is also a menu setting to select the color of the wall, which changes the color balance of the light. There are only a few choices here and I didn't find any of them very effective. You can adjust brightness, contrast and saturation but it seemed that these controls tended to make the picture worse. There were some additional modes that just had me shaking my head: "flashlight", "SOS" and "Warning". These effectively turn this projector into a $20 LED flashlight with various hokey modes.I was pleased with the sound (through HDMI - the only input method, despite Philips' web page claiming others). At least as good as the typical notebook computer.I tried the Philips with PowerPoint presentations, videos and projecting the desktop from my Windows laptop. The PowerPoint was pretty good, as long as the font was big enough. Video was acceptable. The desktop was almost illegible, and I have the icons and text enlarged normally. Details were blurry, despite my best attempt at focusing (a small wheel on the side of the projector) - the focus adjustment was very tricky to get just right. Colors were good overall, but as I wrote earlier, contrast was low.The PPX4835 has a battery and it runs quite nicely on that. The battery can also be used to power a phone or tablet. Philips includes an HDMI cable (the socket on the projector is Mini-HDMI), a power adapter with folding prongs and a nice carrying case that holds the projector itself. There's a small "getting started" leaflet included, but when I went to the Philips web site listed to get a full manual, none was to be found. Nevertheless, it isn't hard to figure out how to use the projector.I am seeing a lot of these portable projectors on the market, all with inflated claims of screen width usability. As long as you temper your expectations, the Philips PPX4835 is a decent projector for smaller spaces/audiences. I can see it especially useful for business travelers who make presentations without needing to depend on the customer having a usable projector - as long as all the viewers can get reasonably close to the screen (no more than 10 feet away, I'd say.) As a bonus, if you're stranded on an island and have your projector charged, you can always flash an SOS to rescuers. (Or use it to find your dropped house keys.)Edit: April 18, 2016I contacted the support service for this projector and they sent me the full manual as a PDF. I neglected to mention earlier that the projector can be set to project as ceiling-hung or rear-projected. It also has a tripod socket on the bottom.It's interesting to note that while Philips' name is on the projector, it actually seems to be a product of a French company called X-GEM.

I was surprised at just how small the Philips PicoPix projector is. This is great for sales meetings, small group meetings or just having a fun movie theatre night. It comes with an HDMI chord, protective sleeve and power chord. The product description says that the projector is compatible with mobile devices, but you’ll have to buy an HDMI/MHL chord separately in order to use this feature. Another glaring omission is that this does not come with any owner’s manual or product guide. The projector is fairly easy to use, but it would have been nice to have a manual of some sort that explains different features or how to access them. I’m still wondering how I would replace the bulb if needed. It does include a quick start guide but you're almost better off figuring it out on your own.The image quality is pretty good, with features that include keystone correction, front/rear/ceiling/rear-ceiling projection options, wall color settings (white, yellow, pink, green, blue) and screen settings. There are a few options that seemed a little odd to include, mainly the flashlight and emergency beacon options. The audio is ok, but not the greatest. You might get better audio plugging an external speaker into the headphone jack. The tri-pod socket on the bottom is a handy feature and makes setting it up much easier without having to worry about leveling it on a desk or some other surface. The USB port is only for charging devices, but I don’t have much use for this option since I use it with my laptop.Overall, the PicoPix projector is a very small, very portable projector that does a great job.

In my husband's line of work, he's very familiar with the use of projectors, slideshows, video presentations, etc. He was really impressed with this little projector. It's not exactly truly pocket sized, but it's definitely small and convenient to carry with you. In its padded cloth travel case, it measures 4.5" x 4.75" x 1.5".The rechargeable battery is a very nice feature, so you can use it even when you aren't sure of access to electrical outlets. No embarrassing moments of trying to rearrange electrical cords, moving everything closer to the outlet, or asking someone to find an extension cord. Just charge it before you go, and you're set.The HDMI adapter cable worked well, since our laptop has an HDMI port. It can also hook up to our blu-ray player easily. The interface is simple, as well. The projected image was clear and bright. We watched youtube videos on the wall, to be honest. Laughing at them all. The speaker would possibly be an issue if you tried to use this in a large area, for a large audience, without additional audio hookups.My kids are plotting all the movies we can watch in weird places. I'm thinking of how simple it will be to share photo montages at future graduation events, weddings, etc. I have quite a few of those left in my future! I don't know what uses my husband had in mind, though he agrees with the kids and myself. I do know he was very impressed, and that says a lot!
