The bottom of the projector has five, short rubber feet that keep it from sliding when you place it on smooth surfaces like cabinets or shelves. 

DBPOWER RD-820 Design review

It comes in either white or black, measures in at 6 x 8.2 x 2.6 inches and weighs just 2.18 pounds. The DBPower RD-810 has a sleek, simple design, and appeared well-made. It also definitely has the kind of dimensions that make it very portable. On the front of the projector you’ll find just the lens and a small checkerboard-style vent that we assumed was installed to prevent overheating. The top is equally as simple. It contains a dial to adjust focus as well as keystone correction, the DBPower logo, as well as a clearly labeled power button with an LED light. 


You’ll find a ton of different connection ports, including a USB port, an HDMI port, a headphone jack, an AV plug, an infrared LED and last but not least, a VGA port. There’s also a power switch as well as a plug to insert the power cord.


It has a native resolution of 800 x 400 pixels and a supported resolution of up to 1920 x 1080p. This maximum resolution won’t make much of a difference if you’re trying to watch any video files with a 4K image resolution, but for most standard HD videos it’ll do just fine.


It has a brightness of 5500 lumens which, for the price, is acceptable, but there are certainly more expensive, more powerful projectors available.

Contrast ratio

It boasts a contrast ratio of 1000:1. For those that don’t know what contrast ratio means, it denotes the ratio of light reflected from a solid white image to a solid black image. In the case of the DBPower RD-810, the white images will be 1000 times brighter than the black images. Again, this capability was good considering the price, but other, more expensive projectors can have contrast ratios of up 10,000:1.

Keystone adjustment – DBPOWER RD-820 review

When it comes to adjusting the shape of your image, you’ll find that the projector has a manual keystone correction of plus or minus 15 degrees. This essentially refers to the amount that you can adjust the shape of an image to fit a projection surface. For example, if a projected image is not perfectly rectangular you’ll need to utilize keystone adjustment. It can also project anywhere between 1.5-5 meters away from your desired projection surface and has an adjustable screen size of anywhere from 20-150 inches.

Image quality

It is capable of projecting in resolutions of up to 1920x1080p, and the projected image had a lot of sharpness and detail with very little distortion. We found that by using a more high-quality HDMI or USB cable, we got significantly crisper images and better projection. The image quality of the DBPower RD-810 is impressive, but could also be affected by the kind of environment in which you use it.


The speakers are LOUD. They’re definitely room filling and will suit pretty much every purpose. They sound a little tinny so if you have your own speaker setup you should use that. But if you’re transporting your projector to a location, the integrated speakers will do nicely.

Extra Long Lamp Life

With a lamp life of an incredible 50,000 hours, you can have several years of usage with reduced upkeep and cost of ownership. Utilizes LED light source and TFT LCD display technology ensures lower energy than conventional bulbs and also longer life up to 50,000 hours.


The remote is pretty simple and easy to use. It lets you further dial in contrast and brightness settings depending on your media and environment. Once everything is tuned, you really only need it for volume control.

Setup – DBPOWER RD-820 review

The unit offers tabletop or mounting options if I later choose to hang it from the ceiling. I used a tripod to easily adjust the height for my wife to display her project for tracings.

Connecting it to my Windows 10 laptop using the HDMI cable was “plug and play”. The projector mirrors my laptop screen. I streamed an Amazon Prime movie, played videos taken from one of my drones and looked at several pictures, all using my wall for a screen.

I connected a 2TB USB portable hard drive to the USB port. The remote control is used to select the media type (“Movie”, “Photos”, “Music“ or “Text”. Select the folder of the file to play. Highlight and select the file. I played MP4, MOV and AVI videos, JPG photos and MP3 music files. All worked flawlessly.
