I’ve been seeing these tiny LED projectors at trade shows for probably close to two years now, and mostly my attitude has been “cute” but too dim to be useful. None-the-less, they have been getting a bit brighter, and I have received emails asking about them, so I turned to Mitsubishi, and asked about a review unit of their 2nd generation PK20. The Mitsubishi PK20 (link to specs) claims a “massive” 25 lumens, a spec that can only make me chuckle, as the first portable projectors (sub 20 pounds) back in 1994, even then, were 110 lumens. Today’s typical LCD and DLP entry level projectors are all over 1000 lumens. So, what, I thought, can anyone do with 25 lumens.
It truly surprised me, but, it turns out that the PK20 is actually bright enough for a lot of things, as you will see in the various photographs in this review. I had hoped to check out the PK20 with the optional battery pack, but, alas, the review unit came without one.
What it’s not, is a serious projector for getting up in front of 20 or 100 people for a presentation. That said, it definitely has enough horsepower for a presentation in front of a couple or three people, with some lights on, probably best at 40″ diagonal, although with lights very low, 60″ is doable.
And it is fun as a game player’s projector, hooked up to an Xbox, Wii or PlayStation… and shining it on a wall or screen. And, since I go camping in the Grand Canyon every year, I’m going to try what someone suggested – shining it on a wall of my tent, or on a sheet, at night – what for, I’m not sure (but maybe a movie played off my laptop, or maybe a music video (I take a good portable iPod compatible sound system with me.)
But enough rambling. Just one more thing. Despite all my misgivings before I started working with the PK20, I am most impressed. While I decided that it really wasn’t appropriate to give it our Hot Product Award, (hey, there are more expensive 2 pound projetors with 40 times the brightness) it is perfect for our far less frequently issued Special Interest Award. So, here it is: Mitsubishi’s PK20, in all of its palm sized, 1.1 pound glory.
i have a Mitsubishi Pocket Projector model PK20 and have lost the power cord and the computer in cord
The PK20 uses a standard HD15 connector cable to interface to a PC. You can buy those anywhere, Amazon, Best Buy, etc.
As to the power cord, if you can’t find a website that can sell one, and Mitsubishi can’t help you (they are still obligated by law to maintain replacement parts, even though they are now out of the projector business), you should be able to source what you need.
The projector or documentation will give you the voltage and current spec. You just have to find the appropriate power brick, For example it might call for 12 volt and 1.5 amp. (I”m just making that one up.) Once you find a suitable power brick, if the connector doesn’t match you should be able to find an adapter. If you are near a Fry’s that’s a great place to start. Radio Shack, while they are still around is another good place… -art
