LG PH300 has a native 1280x720 high-definition resolution with a 16:9 aspect ratio. This is great for playing video content. For a pico-projector, the PH300 also has very decent black levels (the contrast ratio is 100 000:1).
Pro Very small and light
This LG is only 2.5 x 3.5 x 4.5 inches in size. It weighs just one pound.

The lamp lasts for up to 30 000 hours, so you probably will never have to replace it. Replacement lamps for PH300 are hard to find anyways.

Pro Rather quiet fans
The fan noise is a high-pitch whiny noise: 26 dB in normal mode and 28 dB in high brightness mode. The projector is rather quiet, but you can still hear the fans buzzing.
Pro Comes with a battery

Cons
Con Poor sound quality

It is a single-chip DLP projector, so you might experience a rainbow effect on the screen every once in a while.
Con Poor colors
This is not the best pick for playing video content due to its poor colors. P300 is meant for presenting slides.
Con Noisy fans
The fan on AAXA P300 is rather loud, it's comparable to an overheating laptop.
