Have a question on a projector

Hi Everyone! I just started a great job. I have been doing presentations and I want to get a small projector that I can just get out on a moments notice. Sometimes I want to do quick ones inside somebody's office. I tried look on other sites but didn't get much help. I ran into this one on Amazon
Amazon.com: AAXA KP500-01 P4 Pico Projector, 80 Lumens, Pocket Size, Li-Ion Battery, 15000 Hour LED Projector, WindowsCE, Media Player, Black: Electronics
I was wondering what you guys think, I don't know much about projectors. Let me know what you know or other suggestions. Thanks in advance!

 

at 80 lumens, you will need to be in a Dark Room. All of the lights off.

If you are cool with that, then i would get the Optoma one;

If you are looking at projecting in rooms with light.. I would get something at least 1,000+ Lumens.. 2000+ if you are in a room with Sunlight, minimum.

ETA: if you need something In-Between, this isnt bad;

The ML500 is LED, and its fairly small/light.. Not Pico Sized.. but it will do.

 

I've had the Acer K11 for a year now, and it's still going strong. You do have to have the lights off to get maximum brightness, but at 300 (rated) lumens, it would atleast be an improvement over what you're considering.
Newegg and Amazon have it for $340/316. It's my first projector, but I love it, and use it for gaming and watching movies.
