3M Mobile Projector MP220

The MP 220 is includes an impressive set of features. It is amazingly compact and lightweight, especially considering its outstanding brightness. The combination of being capable of running on batteries, plus having its own Android operating system and internal memory, enables you to use it without any cable connected to it which is really a great advantage.

The drawbacks of this projector have to do with its bundled software. While having an operating system and a file system is a real plus, the limited features of the software are somewhat frustrating. Mainly, the "documents to go" bundle, which can play PowerPoint presentations (in addition to opening other MS Office files) cannot play animations or videos embedded in the presentations which takes a lot of the fun of presenting dynamic contents.

Supported video formats are also limited. I had to convert my videos to 720p MP4 files to run internally.

Certainly, when you connect the projector to a laptop (using a separately sold vga-HDMI cable), none of these shortcomings are present, but then you no longer enjoy the possibility to just carry this miniature projector...

One open question I still have (I have sent a question to 3M support) is the size of the internal memory. It is advertised to be 2 GB, while what I see is 765 MB. In any case, if you want to present rich content locally, it is recommended to purchase a larger micro-SD card (up to 32GB is supposed to be supported).

Also, if you intend to run local presentations, I would recommend purchasing the remote control. Without it, you need to touch the projector whenever you want to go to the next slide.

A tripod is a must. I bought the Sunpack spider leg tripod which delivers what I need.

In summary:

The positive:

amazingly compact

very good brightness

runs on a rechargeable battery (supposed to support 2 hours of projection)

can run presentations and videos stored locally, without connecting to a video source

The negative:

limited capabilities when running local presentations

limited video formats when running locally

Additional considerations:

definitely purchase a tripod (or use one you have...)

a remote control is useful when running locally

additional cable is needed to run from other video sources (such as PC)

If you want project your Ipad or Iphone, you'll need cables and conectors!

But Amazon's or 3M's sites don't explain, just in manual.

Cable VGA and conector 30 pin to VGA.
