In a word, No.
Much too dim
Very low resolution
No VGA input
You would be wasting your money and your audience's time.
For Powerpoint to look half decent you want at least 600 ANSI Lumens brightness, but more is better. You can scrape by with a resolution of 800x600 though really 1024x768 is the accepted norm.
You can buy a reasonably competent projector for about £400. Spending more gets you better features, better quality, smaller, quieter, brighter.
If there's money riding on what you are presenting then the safest bet is to hire a projector for the day. Google is your friend.
