It seems that inexpensive projectors are everywhere. Today we’re going to look at an LED-based projector in the $100 range, the DBPOWER T21 1800 lumen LED projector.

The kit came with an HDMI cable, composite video cable, power cord, height screw, remote and manual. A lens cap was already attached to the projector.

This table should give you a pretty good idea on the scaling.  I found the keystone correction dial to be quick and easy to use since it’s a physical adjustment, not pixel tweaking.

I would probably not use the DBPOWER T21 projector for projecting web page text or Powerpoint presentations from a laptop since the native resolution of the projector is only 800×480. In fact, the Amazon page “reminders” even indicates “Not recommended for PPT, word, excel or business presentations.”  I have no way to verify if the projector puts out 1800 lumens, so you need to be able to dim the room completely for best results.  If you can control your ambient lighting and you just need simple video, the DBPOWER T21 is an inexpensive, simple to use projector.

  2. We have one of these DBPower Led projectors at school. Can I project a series of pdfs through it? I’ve tried it through a USB flashdrive and USB connections through an older Dell laptop..and it doesn’t recognize either.
    If this won’t resad a pdf, is that the case with all projectors. Do I need to change all my files into jpgs? I’m new to the digital projector.document camera world… (I still use an overhead and transparencies.)
