With a brightness of 100 ANSI Lumens and projecting images of up to 150 inches, the PK320 extends the functionality and usability of Optoma's Pico line, allowing users to project in more situations. This product, which incorporates a cool metallic look, provides easy and flexible connectivity to a broad range of sources, including tablets, iPhones, DVD players, laptop computers, set top boxes and more.

  • PC Free with Microsoft Office Reader and 2GB memory
  • Truly portable-Palm-sized, lightweight and rechargeable MicroSD card slot for memory expansion
  • 100 Lumens-Project widescreen images of up to 150 inches diagonal
  • LED light source lasts over 20,000 hours while producing excellent color
  • Full assortment of I/O ports, including USB, VGA, HDMI and video, allow for easy connection to most analog or digital devices

Keep Moving

The PK320 supports use with an AC adapter or battery power. On battery, you can achieve typical battery life of over 90 minutes in Eco mode. An optional battery pack extends projection time further and allows you to use the PK320 at full brightness for up to two hours.

New Design Enhances Usability

The PK320 integrates a new and innovative user interface that allows users to access key features more quickly than before. Business users can get presentations going faster than ever before, while entertainment users can access media without keeping their audiences waiting.

LED Design Advantage

The PK320's LED technology delivers low power and silent operation. The same LED technology provides vivid color, durability and long life that make it attractive to price-sensitive small business and consumer users.

The LED light source has an estimated lifetime of more than 20,000 hours (equivalent to using the projector four hours every day for over thirteen years). LED is incredibly cost effective compared to lamp-based projectors. For example, users with a lamp-based projector would have to replace the lamp in the projector at least four times over 20,000 hours of usage-at a cost of over $800, compared to the completely maintenance-free LED lamp.

Leading the DLP Market in the Americas

Optoma Technology is the leading manufacturer of Texas Instrument's DLP projectors in North and South America. TI's DLP features multi-color processing to produce accurate and vibrant colors on the screen.

Green by Design

As part of the Optoma Project Green program, Optoma's Pico projectors, which incorporate LED technology, have been designed and manufactured for eco-friendliness.

Having never owned a pico projector before, I was intrigued by the idea of them. My old projector has a blown bulb, and instead of spending another $300 for a new bulb I decided I would give this a whirl. I spend a lot of time at work or traveling, so I wanted something to have handy if I ever wanted to play a game or watch a video on the go. I just received my pk320 today and here are my initial impressions:

1) Very small
2) Lightweight
3) Still feels durable despite 1 and 2
4) Bright picture....this one shocked me. In my living room with the lights on (granted this took place at night) I could clearly see the picture when projected onto a wall across the room. I imagine the result with my projector screen will be better.
5) Built in card reader and decoder work well. I loaded some avi's onto a memory card to test out how this would work. Not only did it work quickly, it also was able to find the avi's I nested within a folder.
6) Built in speaker works surprisingly well
7) Seems like optoma listened to some of the feedback from earlier models and included a remote and some accessories with this model.
8) Padded case seems nice

1) There is no keystone adjustment feature. This is actually a large issue, in part because of the size of this unit. If you put this on a table/desk/furniture/etc... there's a high chance you will not be directly centered from where you are projecting the image. The tilt up/down/to the side causes very visible distortion in the image shape. It's still watchable, but this seems like a huge oversight for a projector that cost $400+
2) Fan is loud when on "bright" mode (100 lumens). Fan noise is most definitely audible when the projector is running at 100 lumens.

I was very excited about this item for two reasons, its portability, and the fact that the bulb would last a very long time so I wouldn't have to worry about replacing it as I travel internationally. Unfortunately the projector started malfunctioning right off the bat. Within three months I had to replace the cord, it cost sixty two dollars. After I received the cord, within a month the new cord doesn't work correctly. I don't think there's anything wrong with the cord, it appears that at the junction point of the cord going into the projector is a malfunction in the design, as it does not want to sit straight for very long, causing it to not connect correctly, which causes the projection to cease in midstream. Can't watch things very long before this happens.

Also, within six months the pixels I think, the screen started showing one white dot, then after another month it was three, and after a year it's like sixteen white dots on the screen from the lens coat falling apart or something. Bottom line, within one year this thing is a piece of junk, and at four hundred dollars, it s a big disappointment.

I am on the road a lot visiting people in their offices or with small groups. I live by Powerpoint. Before the Optima PK320 Pico Pocket Projector, I was carrying a small laptop, a lightweight projector, a screen, and all the cords needed to power stuff and hook it together. I reduced my weight significantly by getting an iPod Touch and putting my presentations on it, but I was still burdened by cords, projector, etc. Enter the Pico Pocket Projector. It has the ability to project my presentations from a microSD card or usb stick and it can run from battery.

If I am doing presentations in a large room to a lot of people, I still need the big projector, but the PK320 is plenty bright enough for someone's office of small meeting room. Some of my meetings with people inspire ad hoc presentations. I have many preloaded on microSD card in the projector. Now I can whip out the projector and say, "let me show you...". Within seconds, I am able to shine the presentation on a wall. I carry a bright white piece of paper that allows me to throw a 50 inch image. The paper folds down to 8 X 10. No cords. No waiting for extensive warmups. The PK320 is ready to go quickly. Buttons on the top allow me to find the presentation I need quickly and easily. POW - I'm off and running.

I have received comments from some I have given presentations to that they were impressed with my preparedness. When I said, "I have a presentation I would like to show you." I merely reached in my pocket and pushed the power button while I was still talking.

The PK320 has 2 brightness modes. Most of the time, I find that I need the high brightness mode, which eats up battery life or depends on external power (from an external battery pack or wall power).

WOW for the size..... I absolutely love this thing 16ft from the projection surface I got a 112in view-able from this little thing (when plugged in it goes to 100 lumens) I did have to move a few things out of the way and take some things off the wall, just wanted to see how good it would come out. One of the other reviewers said that the hdmi and power were too close together to work, I did try a mini (it is a mini hdmi connection at 720/1080i) and I could get mini hdmi and power pluged into the projector...... of course I did not want to get another cable that I could only use on this thing, so I bought a hdmi to mini hdmi adapter for like $2 buks plug it on the end of any hdmi cable and pooof mini hdmi cable....... well it didn't fit with the power cable plugged in so I had to remove the bulk hard rubberized plastic off one side (x-acto knife) of the adapter then it work perfect. As for battery life I played 19 waves of survival mode on call of duty MW3 with the built in speaker and whatever the brightness is when running on battery (not 100 lumens) I died and put in back on the tv so I dont know how much further I could have gotten. It has a tripod mount I recommend getting a little $1.88 spider leg tripod 3in? or gorilla pod makes it sooo much easier to get that perfect rectangle screen........ when focusing the screen image find something with letters that are towards the center of the screen not the corners you will figure that out the bigger the screen gets, 92in screen size I would say is the best corner to corner diagonal large size, not bad ehh. This thing is crazy impresive with hdmi and 2.1 computer speakers plugged in.......... I dont think it can charge off of the micro usb port in the back but the power light indicator comes on when pluged in to a usb wall port......Read more ›
