Summary:

While there's other projectors out there with better features in one area or another the Optoma PK320 delivers the whole package. It's a projector that covers everything a mini projector should be: Portable, light weight, bright, and highly connectible. We recommend it's use for business as you'll find it's software very compatible with all files you need to present and can be used as a standalone unit. A great buy!

When it comes to business you want that sweet combination of portability, light weight, good brightness and loads of connectivity options.

Most of the time, mini projectors fall down in one of more of these categories, but not so with the Optoma PK320. It’s a well rounded, modern and sophisticated mini projector that is the ideal road companion.

And when you’re at home it does a great job of being a home entertainment unit for impromptu movies with the family. Let’s take a closer look at some of the features…

Mini Projector Features

Optoma PK320 Mini Projector There’s very few bad points about this rigid mini projector and loads of positives.

Weighing in 8.3 oz. (235 grams) with the Standard Battery installed and being only 4.7″ x 1.2″ x 2.7″ (120mm x 30mm x 70mm) you can say that the Optoma PK320 is truly portable. In fact it sits in the palm of your hand.

This is great because for a business person on the go you need a unit that isn’t going to add a lot of weight to your carry on luggage or in your laptop back when going out to presentations.

Usually the sacrifice of this portability is brightness and image quality. Not so with the Optoma PK320, in fact it has a very high 100 ANSI lumen brightness rating and the image can project comfortably to 120″ (over 3m) and apparent can stretch to 150″ (3.8m). The contrast ratio is 3000:1 as well which should give quite vibrant colors in a range of lighting scenarios.

The standard resolution is Native WVGA (854 x 480) and can support a range of video inputs such as HDTV (720p, 1080i), EDTV (480p), SDTV (480i), NTSC, PAL. For PC compatiblity expect WXGA, XGA, SVGA, VGA, VESA, PC and Macintosh Compatible.

Optoma PK320 Mini Projector This mini projector has a very wide range of connectivity options thanks to a universal input with an included adapter. Included connectivity ports are:

  • Mini HDMI
  • microSD Slot
  • 24-Pin Universal Port for VGA
  • 2.5 mm AV Input (Composite Video and Stereo Audio-In)
  • Micro USB
  • 3.5 mm Audio-Out
  • DC Input

The software included is quite good as well with the ability to be completely untethered from your laptop or PC. Just insert your microSD card or USB stick and you can play the media direct with the onboard software. The software also comes in 15 languages.

Video compatibility for AVI, MOV, MP4, 3GP, CMB, FLV, WMV, ASF is supported. You can view JPEGs and BMP image files and you can also play your Office documents straight from the projector, Microsoft PowerPoint (PPT, PPTX), Word (DOC, DOCX), Excel (XLS, XLSX), Adobe (PDF) are all compatible.

There is also audio compatibility for AAC, MP3, ASF, FLAC, RA, OGG, WAV, WMA but I’m not sure why you’d want to play a song through this unit’s crappy 1W inbuilt speaker. Thankfully there’s an audio out port so you can plugin headphones or better yet a set of powered speakers. This should definitely enhance your presentations.

While we’re on negatives, the main gripe we had was the Lithium ION battery only lasts 90 minutes (on ECO) and 45 minutes on standard brightness settings. 45 minutes is pretty unrealistic and hardly enough to do a long presentation.

Thankfully, there is an extension battery available (here on Amazon) that adds another hour and a half to the standard 45 minutes bringing total battery life up to 2 hours.

The Optoma PK320 comes with a 1 year limited parts and labor warranty and a 90-day warranty on the battery.

Mini Projector Technology

Optoma PK320 Mini Projector The Optoma PK320 uses a Texas Instruments DLP lighting system with a super bright RGB LED light source. This delivers over 20,000 hours of lifetime from the lighting engine.

LED mini projectors are low power and therefore more environmentally friendly than their lamp driven cousins. LEDs do not contain mercury or other environmentally hazardous materials.

The unit only consumes 19 Watts peak with bright mode on and using multimedia functions.

Conclusion

While there's other projectors out there with better features in one area or another the Optoma PK320 delivers the whole package. It's a projector that covers everything a mini projector should be: Portable, light weight, bright, and highly connectible. We recommend it's use for business as you'll find it's software very compatible with all files you need to present and can be used as a standalone unit. A great buy!
