Projectors are exceptionally helpful for mobile presentations to groups of people.
Here are a few qualities to look for in a projector:
If traveling in the mountain areas, at higher altitudes projectors runs the risk of overheating much faster than at sea level or below the recommended altitude. Normally the projector can run for 4-5 hours before overheating. At high altitudes the timeframe is closer to 2-3 hours, but supposedly it can still be used. This appears to be a general rule for projectors and not specific to any model.
